Why we like Ritual Synbiotic+ as best overall

Ritual Synbiotic+ is a comprehensive gut health formula. Ritual sets themselves apart from other supplement companies with their supply chain transparency and dedication to sustainable practices. They take this same approach when creating their supplements.

Synbiotic+ is a 3-in-1 formula with prebiotics, probiotics, and postbiotics. Prebiotics feed the friendly bacteria in your gut. ( 3 ) Probiotics are the source of friendly bacteria. ( 3 ) Postbiotics are substances that support the well-being of the microorganisms. ( 4 )  Grouped together, these substances are called synbiotics.

Your gut microbiota, or the makeup of the organisms that live in your large intestine, has a significant influence over your health. ( 5 ) It helps with digestion, makes nutrients, and supports the immune system. Researchers also find that the balance of good bacteria to bad bacteria in the gut can affect weight and risk of chronic diseases like obesity and Type 2 diabetes. ( 5 )

Certain strains of microorganisms may have the potential to help people with obesity lose weight and fat. ( 2 ) Synbiotic+ contains some of the strains linked to weight loss— Lactobacillus rhamnosus and Bifidobacterium species. However, in many of the researches studies we reviewed, participants who lost weight while taking probiotic supplements also followed a calorie-restricted diet, an exercise program, or both. ( 2 ) This research suggests that probiotics may help you reach your weight goals if you also eat a balanced diet and get regular physical activity.

Synbiotic+ has a special capsule that protects the microbes, ensuring as many organisms as possible reach the colon. Our testers said they had no problems swallowing the capsule and liked the minty taste.

Bowel regularity and improved bowel health are additional potential benefits of Synbiotic+. One of our testers said she had more regular bowel movements and less bloating with trigger foods while taking Synbiotic+. Another tester also saw improvements in digestion but was unhappy about the price so she stopped taking it.

At $54 a bottle, Synbiotic+ is on the higher end of what we’ve seen for probiotics. However, it’s one of the most comprehensive supplements we’ve come across. Buying this 3-in-1 probiotic means you only need one supplement, not three.

Another drawback of Synbiotic+ is its use of proprietary blends, a secret recipe for a mix of ingredients in the supplement. With a proprietary blend, supplement makers only have to list the ingredients in the blend, not the amounts. Without knowing the dose of individual ingredients, you can’t determine any potential risks or whether you’re getting the most effective dose. ( 6 )

What customers are saying

Customers on Amazon say the supplement is easy to take and gentle on the stomach. Some customers also say the price is too high and they have received damaged merchandise.

“These have made me feel so much better. Not to be TMI, but my toilet and I are finally friends and not enemies. They can be a bit pricey, and you get the occasional fishy burp, but I wouldn’t trade them for the world.”

Jay, Amazon

Stephanie, another verified customer, says it’s the best probiotic she’s ever tried.

Mary FE is a verified Amazon customer who didn’t tolerate the supplement. “I love their vitamins so I thought I’d give these a try. Very disappointed. Very expensive. I’ll stick to my old synbiotic that gave me zero issues.”

Why we like Transparent Labs Probiotic as best for constipation

Transparent Labs Gut Health Probiotic is our pick for the best probiotic for constipation and weight loss due to its choice of probiotic strains. Transparent Labs’s probiotic formula has 10 well-researched strains that offer several health benefits.

Your gut is home to trillions of microbes. ( 3 ) Lactobacilli and Bifidobacteria are the two most studied groups of bacteria in our microbiome, each with numerous species, and research shows they affect the immune system, skin, digestion, and heart health. ( 3 ) Transparent Labs Probiotic contains both of these strains.

A microbiome with low levels of these strains may affect the digestive system. Studies show that people with chronic constipation have lower levels of these two strains in their gut, but supplementing with probiotics that have Lactobacilli and Bifidobacteria species can help. ( 7 )

Certain strains of Lactobacilli, including L. acidophilus , are unable to fully break down fructose and glucose and may cause weight gain. ( 2 , 8 ) However, some studies show that Lactobacilli and Bifidobacteria can help improve body weight, lower body mass index (BMI), and decrease waist circumference in adults who are overweight or obese. ( 9 ) While these are promising results, the authors of the study recommend more research to confirm their findings.

The creators of Transparent Labs Gut Health Probiotic engineered their formula to promote a healthy gut microbiome and the benefits that come with it. It contains 100 billion colony-forming units (CFUs).

Probiotics are measured by CFUs. Most supplements have between 1 and 10 billion CFUs but can go higher. However, according to the Office of Dietary Supplements (ODS), part of the National Institutes of Health (NIH) that explores the science of dietary supplements, more CFUs doesn’t mean better results . ( 3 ) In fact, different stains can have different levels of proven support. The CFUs in the Transparent Labs Gut Health Probiotic may go beyond what you need.

In addition to its formulation, we also like Transparent Labs Probiotic because it’s third-party tested for banned substances, is gluten-free, and has no artificial ingredients.

At $46 for a 30-day supply of probiotics, this supplement is on the average-to-high end for probiotics. You need to take it on an empty stomach, which you may find inconvenient if you forget to take the supplement before you eat. You can also only buy the supplement from the company’s website, so you can’t shop around for the best price.

  • Our product testers said the capsules were easy to swallow and small enough that they could take two at a time.

  • This probiotic is a great choice for people who want a total body supplement that supports their nutrition and fitness goals.
  • Legion offers a subscribe-and-save program that lowers the price of their probiotic to $45.

Why we like Legion Biome as best prebiotic combination

Legion Biome contains four ingredients that are hand-selected and dosed based on scientific research. It’s a 2-in-1 formula, combining a prebiotic and probiotic to nourish and promote the beneficial bacteria in the gut that can help with weight loss.

The probiotics in Legion Biome include Bifidobacterium lactis , Lactobacillus plantarum , and Bacillus subtilis .

B. lactis nurtures the gut, helps make certain nutrients, and counteracts the effects of toxic substances in the gut to reduce inflammation. ( 1 ) Bifidobacteria species are also linked to weight loss, alone or with other probiotics. ( 2 )

Lactobacillus plantarum improves absorption of nutrients, plays a role in the production of short-chain fatty acids that help maintain the microbiome, and may aid weight loss. ( 1 ,2 , 10 ) When taken by itself, it may lower body weight and improve waist circumference. ( 2 )  However, in another study we reviewed, the participants also decreased their caloric intake while taking the probiotic. ( 11 ) This suggests that while probiotics can support weight loss efforts, a calorie deficit is still an important element.

Bacillus subtilis supports immune health and may help with appetite control and metabolism by improving the body’s absorption of protein. ( 12 )

The prebiotic in Legion Biome is xylooligosaccharide, a carbohydrate naturally found in fruits, vegetables, and milk that supports the growth of the good gut bacteria. It is believed to be effective at a lower dose, so you get more of the benefits with fewer side effects.

Legion Biome is made with all-natural ingredients and lab tested for potency and purity. You can see the most recent third-party lab test results on Legion’s website.

At $50 a bottle, or $1.67 per serving, Legion’s probiotic has a higher price point than other supplements, but it’s a high-quality supplement that’s third-party tested for safety and potency. This means it contains what it says on the label. It’s not clear if it’s allergen-free or suitable for vegan, gluten-free, or dairy-free diets.

Our product testers had no problem taking the two capsule doses, saying it was easy to swallow. The instructions are specific and recommend taking the probiotic first thing in the morning with food.

What customers are saying

Most customers at Amazon give Legion Biome positive reviews. They say it helps with bloating and gas, improves digestion, and benefits overall health.

Verified Amazon customer Courtney A. says the capsules are easy to swallow and tasteless, and haven’t affected her regularity in any way.

Some customers said they didn’t notice any changes in digestion after taking Legion Biome. Others reported gastrointestinal problems.

Martyn B., a customer on Amazon wrote, “I deliberately chose this brand as it has a very good reputation and lots of satisfied customers, but unfortunately after trying these for a few days I ended up with a lot of gas.”

  • Nutricost Probiotic Complex provides two months’ worth of probiotics in one bottle.
  • At $19.95 a bottle, or $0.33 per serving, Nutricost’s probiotic costs less than the market average.
  • This supplement is best for adults who want a simple but effective probiotic to replenish the friendly bacteria in their digestive tract without the high price.

Cons

Why we like Nutricost Probiotic Complex as best affordable

Nutricost Probiotic Complex provides the beneficial microbes your gut needs without a high price. One bottle costs $19.95 and has a two-month supply of capsules. The dose is one capsule a day, so you pay $0.33 per daily dose. By far, Nutricost Probiotic Complex is the most affordable gut friendly probiotic on our list and half the price of most probiotics on the market. You can save even more with a subscription.

Additionally, Nutricost Probiotic Complex has many of the same friendly strains of bacteria found in other supplements, including Lactobacilli and Bifidobacteria. Research suggests these strains may help with weight loss efforts and keep you regular. ( 2 , 10 )

One of the ways probiotics can help with weight management is by increasing production of the hunger-controlling hormone glucagon-like peptide 1 (GLP-1). ( 2 ) This hormone is made in the lower part of the digestive tract. ( 13 ) It slows down the movement of food, keeping you full longer. It also activates the satiating center in the brain, letting you know you’re full. Nutricost’s probiotic may influence your appetite, helping you eat less to support your weight goals.

Nutricost keeps their probiotic formula simple and clean. The supplement is non-GMO and gluten-free. It’s suitable for people who follow a vegetarian diet, but may not work for those on a vegan diet because probiotics in supplements are often grown in a dairy starter culture. ( 14 )

Each batch of Nutricost Probiotic Complex is third-party tested at an independent and accredited lab. The supplement has a CFU count of more than 50 billion. However, you may not get the full dose of microorganisms since the capsule isn’t enteric coated, so it may not fully protect the microbes as it travels through the stomach and small intestine.

What customers are saying

Amazon customers rate Nutricost Probiotic Complex favorably. They like the price and note that it helps calm the stomach and support sleep.

Verified Amazon customer DS says, “Great product for a reasonable price.” Other customers agree.

Verified Amazon customer with the username C says Nutricost probiotic helped them recover from colon surgery. “I had part of my colon removed a year ago and had to wear an ostomy bag. In January, 22 they put me back together and my body works better than ever thanks to an excellent surgeon and the Nutricost Probiotic. I highly recommend this product.”

Some customers were concerned about how to store the supplement. One customer reported having an allergic reaction.

Why we like Biotics 8 as best men’s

Many factors influence the gut microbiome, including genetics, diet, and sex. Though in the early stages of research, studies show that the specific strains of microorganisms in the gut differ in males and females. ( 15 ) Biotics 8 is a specialized probiotic supplement made for men to improve health and performance.

The probiotics in Biotics 8 were hand-picked based on scientific research and effectiveness. It has a proprietary blend of 10 live strains of friendly bacteria, including strains of Lactobacilli and Bifidobacteria to support digestion, the immune system, and body composition.

Biotics 8 also contains a yeast called Saccharomyces boulardii to reduce inflammation in the colon and help prevent or ease diarrhea. According to research, S. boulardii may keep the lining of the digestive tract healthy and help maintain the balance of good bacteria and bad bacteria in the gut. ( 16 )

People with obesity are more likely to have lower levels of vitamin D, which your body needs to make hormones, keep bones strong, and support immune health. You can get vitamin D from sun exposure or foods like fortified milk, eggs, and fatty fish, but most people have a hard time getting enough without supplementation. ( 17 ) With 10 micrograms of vitamin D, Biotics 8 can help you meet your daily vitamin D needs.

However, if you take another multivitamin supplement , check the label to see how much vitamin D it provides so you don’t get an excessive amount. According to guidelines, 100 micrograms  (4000IU) a day is the tolerable upper limit (UL), or the level that when consumed over extended periods is not linked to problems. ( 17 )

Biotics 8 also contains digestive enzymes and chicory root, a prebiotic. It’s not clear if the supplement has an enteric coated capsule to ensure you get the full dose of probiotics.

One downside of Biotics 8 is that you have to take three capsules daily. Instructions on the bottle suggest starting with one capsule and slowly increasing to the recommended three capsules a day over the first 10 days. This gradual introduction may prevent unwanted side effects like gas or bloating.

Biotics 8 is expensive and double the average market price for probiotics, with a retail price of $79.99 for a one-month supply. The company offers a discount and gives you a free month’s supply when you buy two months’ worth of pills at one time.

What customers are saying

Outside vendor reviews for Biotics 8 are limited.

Customers on Trustpilot had concerns about ingredient source. The website says the probiotic is made in the USA, but the product ships from the United Kingdom. Another customer was unhappy with the timeliness of customer support, saying it took two days for a customer service rep to respond to an email.

Non-GMO verified
Vegan certified
Gluten-free
Priced below average market cost
Cons

Uses a proprietary blend
May cause unwanted side effects like gas or abdominal pain

Why we like Sports Research Daily Probiotics as best non-GMO

We chose Sports Research Daily Probiotics as the best non-GMO probiotic for weight loss because it’s non-GMO verified, third-party tested, vegan, and gluten-free. It has a delayed-release veggie capsule that ensures most of the microbes make it to the large intestine alive.

GMOs are foods whose genetic coding is altered using various forms of technology. GMO plants allow farmers to continuously spray crops with herbicides without harming the plant they grow for food. Herbicides contain toxic substances, and overspraying may increase levels of these toxins in the food we eat. ( 18 ) Looking for non-GMO items reduces exposure to toxins and the risks they bring, like the potential for developing cancer. ( 18 )

At $24.95 a bottle, Sports Research Daily Probiotics costs less than the average market price for probiotics and is one of the least expensive supplements on our list. With subscribe and save, the price drops $21.21, or $0.71 per capsule.

However, Sports Research uses a proprietary probiotic blend of various friendly strains of microorganisms that provides a total 60 billion CFUs. Because it’s a proprietary blend, the CFUs for each individual strain are unknown. The prebiotic in the supplement is also a proprietary fiber inulin blend that includes inulin, organic acacia senegal gum, and organic apple fiber. It’s unclear how much of each ingredient is in the blend.

Another concern we have about Sport Research’s probiotics is storage. The supplement maker highlights that it has a long shelf life when properly stored. But they don’t give clear instructions on how to store the supplement with this statement. They say it’s shelf-stable and in smaller print in another area, they say “best stored refrigerated.”

If you don’t store probiotic supplements properly you risk harming the microorganisms, making them less effective. ( 19 )

What customers are saying

Sports Research Daily Probiotics has more than 5,000 reviews on Amazon. Customers like the quality of the supplement and that it’s easy to take.

“These daily probiotics have been a true lifesaver for my easily irritable gut!”

Another verified customer on Amazon who goes by “ejt07” says, “High quality and got everything moving in the right direction. Have tried several in the past that may not have been the right ‘mix’ for me but these things work.”

Negative reviews center around side effects like gas and bloating and lack of improvements in symptoms. Verified Amazon customer Mundioppa writes, “I am still having a gas problem. It does not seem to work well.”

Why we like YourBiology Gut+ as best women’s

YourBiology Gut+ is a complete gut health supplement for women with probiotics, prebiotics, and digestive enzymes. It also has 10 micrograms of vitamin D.

The proprietary blend of bacteria has 10 strains of gut-friendly microbes, including strains of Lactobacilli , Bifidobacterium , and Saccharomyces boulardii . Unlike other supplements with proprietary blends, YourBiology lists CFUs for each strain.

The blend may help rebalance the gut microbiome and improve immune health, digestion, energy, and focus. YourBiology also says its formula helps women feel lighter and slimmer by curbing the appetite and improving bowel movements.

The formula contains the prebiotics inulin and fructooligosaccharides (FOS). FOS are hard-to-digest carbohydrates found in foods like onions, asparagus, and bananas. They may trigger IBS symptoms in some people, but short-chain FOS may improve symptoms in other individuals. ( 20 , 21 ) If you have IBS, you may want to talk to your doctor about probiotic supplements before adding them to your routine. However, the levels of FOS and inulin in this product are very low.

YourBiology Gut+ is gluten-free, dairy-free, and soy-free and suitable for vegan diets. It’s also third-party tested for ingredients and quality and doesn’t require refrigeration.

Like other probiotics on our list, YourBiology Gut+ is expensive, retailing for $80 for a 30-day supply. That’s double the average market price for probiotics. The brand’s website frequently offers a discounted price of $65. YourBiology encourages buying in bulk, offering two free bottles when you buy three at one time. This can save you about $160.

Our product testers liked the clear, detailed instructions for starting the supplement. You take one capsule for the first four days, then two capsules for the next four days, reaching the recommended daily dose of three capsules by day nine. Our reviewers believe the gradual introduction prevented unwanted side effects.

  • Seed’s Daily Synbiotic contains proprietary blends and a long list of ingredients that consumers should review before purchasing.

Why we like Seed DS-01 Daily Synbiotic as best for belly fat

Seed DS-01 Daily Synbiotic is a popular 2-in-1 probiotic and prebiotic supplement for adults. The makers of DS-01 Daily Synbiotic only use clinically studied strains of bacteria in their formulas. Their adult probiotic supplement, DS-01 Daily Synbiotic, is a broad-spectrum formula with 24 strains of microbes, each selected for its benefits.

Probiotics aren’t a replacement for lifestyle changes that lead to a healthier weight, but a supplement may support your efforts. Seed DS-01 Daily Synbiotic contains strains of microbes shown to support weight loss. ( 2 ) This includes several strains of Lactobacilli and Bifidobacteria , the two species that may produce the best results for improving body weight, whether taken individually or together. ( 2 )

That said, no supplement, food, or exercise gives you the ability to pick and choose where you lose weight. Diet, activity levels, genetics, and overall health all influence which areas of the body slim down the fastest. To reduce body fat, you need to create a calorie deficit that forces your body to burn fat for calories (energy). ( 22 ) In turn, you get smaller all over, not in just one specific area.

Seed DS-01 Daily Synbiotic stands out from other supplements because of its broad-spectrum proprietary blends that support digestive health, skin health, heart health, and micronutrient synthesis. It also has Indian pomegranate, a prebiotic well-tolerated by people with IBS.

Seed’s probiotic is gluten-free, allergen-free, and vegan. It’s also third-party tested for safety. The dual capsule design features an outer prebiotic capsule and inner probiotic capsule. It’s engineered to improve survival of the microbes and ensure your body receives optimal doses once the capsule reaches your large intestine.

Though we find the formulation of Daily Synbiotic impressive, it contains a lengthy list of microorganisms. Individual probiotic needs vary and depend on health history and usual diet. Our experts recommend carefully reviewing the list and discussing the supplement with your doctor to determine the potential benefits before starting.

At $50 for a 30-day supply, Seed’s Daily Synbiotic is higher than average for a probiotic supplement. But given its broad-spectrum formulation and high-tech capsule, we think it’s a good value.

What customers are saying

Most reviewers on Amazon find the supplement effective, though some report unwanted side effects.

“I have been using Seeds DS-01 probiotics for a few weeks now and I couldn’t be happier! Not only does it work but it surpasses the effectiveness of other probiotics I’ve tried in the past.”

Natalie is another verified customer with a positive review. “These capsules are really easy to take and have been keeping me regular.”

Why we like Renew Life Ultimate Care Probiotic as best for gut health

Improving gut health is one reason many people take probiotic supplements. Help with weight loss efforts is a side benefit. We selected Renew Life Ultimate Care Probiotics as best probiotic for gut health and weight loss because of its formulation.

Renew Life’s probiotic formula contains strains of microbes that may improve the balance of good bacteria to bad bacteria, promote digestive health, and improve bowel regularity. The gut-benefitting strains include Lactobacillus rhamnosus , Bifidobacterium infantis , Lactobacillus acidophilus , and Bifidobacterium lactis . ( 3 , 7 )

Some of the strains that benefit the gut may also help with weight loss. Additionally, Renew Life Ultimate Care Probiotic contains other microorganisms linked to reductions in body weight, including Lactobacillus gasseri , Lactobacillus casei , and Lactobacillus plantarum . ( 2 )

The combination of strains in the supplement may play a role in how well it helps with weight loss. A randomized, placebo-controlled clinical trial found that a synbiotic supplement with L. acidophilus , L. casei , and Bifidobacteria may improve body weight in adults who are overweight or obese. ( 23 )

Renew Life Ultimate Care Probiotic also has a delayed-release capsule to improve potency and quality. One capsule supplies 150 billion CFUs, a very large dose. ( 3 ) But more doesn’t always mean better.

The probiotic is gluten-free, non-GMO verified, and soy-free. But like many probiotics, Ultimate Care Probiotic is an expensive supplement at $70 for 30 capsules, so it may not fit all budgets. On top of the price, you must keep the supplement refrigerated, making it harder to safely purchase online or carry with you and take at a convenient time.

There’s no mention of how Renew Life keeps the supplement cold during shipping, but some customers say that the supplement isn’t always shipped with a cold pack.

What customers are saying

Most people who purchase Renew Life Ultimate Care Probiotic have positive things to say. They like the quality of the supplement and how easy it is on the stomach.

“These are incredibly effective. This probiotic contains strains that others do not.”

Username “GB,” Amazon

Jonathan, another verified customer on Amazon says, “This is the best and I mean the best probiotic on the market. I am a little worried that ordering it from Amazon means risking the cultures dying off by not being in the appropriate temperatures, but if you can get your hands on this, you will be touching the best probiotic there is. I have never had such a dramatic increase in energy from any other probiotic.”

Some customers aren’t happy about the high cost and that it isn’t always delivered cold. An Amazon customer who goes by “me” writes, “It’s an expensive probiotic and only works if cold. I’ve gotten it three times and only once had it come with a cold pack. It’s not worth the risk the seller does not pack it properly.”

What you should know

Unbloat is a comprehensive formula consisting of probiotics, prebiotics, digestive enzymes, and nutrients that may help manage inflammation. It also contains herbal supplements to help with bloating.

  • Our product testers had a hard time following the very specific instructions on how to take the supplement. The label says to take two capsules within 30 minutes of eating and to take an extra pill when eating hard-to-digest foods.
  • One bottle of Unbloat contains 30 servings (60 capsules) and costs $65.95, or $2.20 per serving. It’s on the high end of pricing for probiotics, but similar to the price of many other probiotics on our best list.
  • This is a good supplement choice for someone looking to ease bloating and gas.
  • Our product tester pointed out that it may take up to eight weeks to see benefits.

Why we like Unbloat as best for bloating

While time is the primary treatment for bloating, taking a probiotic can help. We like Unbloat because it contains a number of ingredients that help digestion, including digestive enzymes, peppermint, fennel, and ginger, along with probiotics linked to weight loss.

Fennel is a home remedy for gas and bloating and the top bloat-fighting herb in the blend. The herbal supplement contains antispasmodic agents that support intestinal motility, easing the  bloated feeling. ( 24 )

Many people turn to peppermint oil as a natural remedy to ease IBS symptoms, abdominal pain, and indigestion. Some research shows that taking enteric coated peppermint oil capsules may help these symptoms. ( 25 )

Unbloat also contains milk thistle, an herbal supplement people use to treat liver and gallbladder concerns and indigestion. It’s not known how well it might help with bloating. ( 26 ) However, the digestive enzymes in Unbloat may also reduce side effects from hard-to-digest foods like beans and broccoli. And, the supplement contains the strains of Lactobacilli and Bifidobacteria , which are associated with weight loss.

Unbloat is gluten-free, vegetarian, and non-GMO-verified. However, it doesn’t seem to have third-party testing for quality or safety. Unbloat comes with a higher price tag, retailing for $65.95 a bottle, but is still within the average range for the probiotic market. You can save about $6.75 per bottle when you subscribe to Unbloat’s quarterly delivery plan, getting a three-month supply every 90 days.

Our product testers found the instructions for when and how to take Unbloat difficult to follow. The company recommends taking one pill within 30 minutes of eating and adding an extra pill when eating food that’s extra rough for digestion.

Our testers also pointed out that the website says it takes six to eight weeks to see the benefits

What customers are saying

Customers on Amazon have mixed reviews about Unbloat.

Verified customer Jackie says Unbloat is a game-changer and plans on ordering more.

Lizzie L. also likes Unbloat, remarking, “While this hasn’t been a miracle where I immediately noticed a difference, I definitely noticed enough of an incremental improvement. I definitely feel less bloated and feel like my body is better processing regularly.”

Another verified customer on Amazon who goes by “RCP” wasn’t happy with the supplement and said it caused stomach pain and bloating.

What you should know

Better Body Co. Provitalize is a women’s probiotic aimed at relieving menopause symptoms, easing belly bloat, and assisting with weight loss.

  • Provitalize contains a mix of probiotics and herbal supplements to rebalance the gut microbiome and eliminate bad cholesterol.
  • At $49 a bottle, or $1.63 per serving, Provitalize comes with a higher-than-average price tag but is similar in cost to other probiotics on our list.
  • Provitalize is for women looking for a natural approach to managing menopause symptoms.
  • While Provitalize claims to improve fat breakdown, there’s no evidence that the ingredients in this supplement increase fat metabolism.
Pros
Vegan-friendly
Free of stimulants and caffeine
All-natural ingredients
Contains strains of bacteria linked to weight management
Cons
Herbal ingredients may cause unwanted side effects
Falls on the higher end of the price range

Why we like Better Body Co. Provitalize as best for menopause

Better Body Co. Provitalize has a simple formula with all-natural ingredients and good manufacturing practice (GMP) certification.

Provitalize has a short list of probiotics that can help with bloating, digestion, and gut health, including Bifidobacterium breve , B. lactis , and Lactobacillus gasseri . It provides 68 billion CFUs.

L. gasseri, in particular, may help decrease body weight, waist circumference, and belly fat—common concerns during menopause. ( 2 ) In a randomized, double-blind, placebo-controlled trial, volunteers with a BMI between 25 and 35 received 10 billion CFUs of L. gasseri for 12 weeks in combination with a 200-calorie deficit and increased activity. The participants showed improvement in visceral fat, the unhealthy fat in the belly that surrounds the vital organs. ( 27 )

For menopause, the other probiotics help with bloating, digestion, and gut health.

The herbal supplements in Better Body Co. Provitalize include moringa leaf for its anti-inflammatory and antioxidant effects and turmeric and curry leaf for joint health. ( 28 , 29 )

We also like Provitalize because it’s made from all-natural ingredients without additives or fillers, and it’s GMP-certified. Additionally, the supplement is vegan and free of gluten, caffeine, and other stimulants. Most probiotics are stimulant-free, but it’s likely Provitalize calls this out because of its inclusion of herbal supplements and focus on weight management.

The makers of Provitalize claim that the supplement reduces gas, improves body composition, and boosts energy. However, the ingredients may cause unwanted side effects like an upset stomach from the moringa leaf. The turmeric may also interact with medications like aspirin or ibuprofen, increasing risk of stomach upset. Talk to your doctor before adding any supplements like Provitalize to your routine.

The Better Body Co. menopause probiotic is priced above the market norm at $49.00 for a 30-day supply. You can save about $9 a bottle by ordering a 90-day supply upfront.

What customers are saying

More than 33,000 people on Amazon have rated Provitalize. A large percentage of people have favorable things to say, but a few customers report that it doesn’t work as claimed.

“Bought one bottle to try. Is expensive, but seems to work. I have lost 4 lbs already. No dieting. Just not as hungry. No need for the miralax anymore. Sleeping all night even though I just take one in the morning.”

Loretta K., Amazon

Verified Amazon customer Lizette M. was hopeful when they received the supplement, but reported that it aggravated their IBS.

How we test probiotics for weight loss

We know how hard it is to eat a balanced diet all the time, so we turn to supplements to fill in nutritional gaps. Choosing the right supplement that fits your goals and needs can make a world of difference. When selecting the best probiotics for weight loss, it’s important to take into consideration the ingredients, dose, how it helps, and how it makes you feel.

Our goal is to give you all the information you need so you can confidently choose a probiotic formula that aligns with your needs.

You can read our full supplement testing methodology here.

Efficacy—40%

Consumers turn to dietary supplements to achieve certain health goals. Efficacy is the core criteria of our supplement evaluation process. We want to know if the supplement delivers on its promise and that there’s scientific evidence to back up claims.

Here’s what we look for:

  • Clinical evidence
  • Dose efficacy
  • Synergistic effects
  • Proprietary blends

Safety and side effects—35%

Consumer safety is a top priority. When evaluating the best probiotics for weight loss, our testers take a close look at every ingredient and formulation for potential health risks, adverse effects, and safety. Consumers should be confident in knowing that the supplement they buy provides the benefits they desire without unwanted side effects. We evaluate:

  • Reported side effects
  • Third-party testing
  • Manufacturer accreditation
  • Artificial sweeteners

Value—20%

Price is important because it affects buying decisions. But to us, value isn’t about finding the cheapest supplement. It’s about finding products that offer a return on investment, meeting individual needs using quality ingredients that are safe and effective.

Our factors in this rating include:

  • Total price per bottle
  • Price per serving

Customer experience—5%

When evaluating customer experience, we look at how easy it is for customers to find and buy the product and the type of support they get from the supplement maker afterwards. This category influences customer satisfaction, loyalty, and the likelihood of repeat purchases.

Our factors in this rating include:

  • Ease of purchase
  • Shipping and returns
  • Customer support

How to choose the best probiotics for weight loss

When choosing the best probiotic for weight loss, review the probiotic strains in the supplement. Not all strains of probiotics support weight loss and research is in the early stages.

Some of the strains of microbes linked to weight loss include: ( 2 )

  • Lactobacillus gasseri
  • Lactobacillus casei
  • Lactobacillus rhamnosus
  • Lactobacillus curvatus with Lactobacillus plantarum
  • Different strains of Lactobacillus acidophilus
  • Lactobacillus acidophilus with Bifidobacterium infantis
  • Lactobacillus acidophilus with Lactobacillus casei and Bifidobacterium

This list is preliminary, and as we learn more the types of probiotics that support weight loss may change.

You also want to look at dosage and storage. Most clinical studies looking at probiotics and weight loss used doses ranging from 1 million CFUs to 50 billion CFUs. ( 2 ) Probiotics are live microorganisms and lose their potency if not stored properly.

Also, look for third-party testing to make sure the supplement contains the ingredients listed on the label and is safe. ( 30 ) Some supplements display third-party testing certifications on the label, while others provide testing information on their website.


Probiotic foods to help with weight loss

While supplements are convenient, you may get more benefits eating probiotic foods on your weight-loss journey. These foods contain other nutrients not available in a supplement that benefit overall health.

Probiotic foods are fermented foods. Fermentation is a food preservation process used for thousands of years. ( 31 ) It involves introducing a microorganism—yeast or bacteria—into a food to prevent spoilage.

Probiotic foods that may help with weight loss include:

  • Yogurt
  • Kimchi
  • Kefir
  • Sauerkraut
  • Miso soup
  • Tempeh

Check the label for storage instructions. This is important for keeping the microorganisms in the food alive. Look for products made without artificial ingredients to reduce the risk of side effects like headaches or stomach upset. We also recommend looking for foods low in added sugar to limit intake of nonnutritive calories.


FAQs

What probiotic is best for weight loss?

No single probiotic is best for weight loss. Research shows certain strains of Lactobacilli such as L. gasseri and L. rhamnosus , as well as Bifidobacteria, may potentially support weight loss and reduce fat mass, but more research is needed.

How quickly do probiotics work for weight loss?

According to the available research, it can take up to 12 weeks to see noticeable changes in weight and fat mass with probiotics. ( 2 ) Eating a balanced diet and getting regular exercise while taking probiotics may help you get better results.

Which probiotic is best for losing belly fat?

Studies show that L. gasseri i s the best probiotic for losing belly fat. In a small study, a group of volunteers taking 10 billion CFUs of L. gasseri experienced a decrease in abdominal fat over the 12-week study period. ( 27 )
