If you, too, have been slow to embrace collagen supplements, consider this: “Collagen is really critical to our health because it makes up 30% of all of the protein in our bodies,” explains Josh Axe, D.N.M, a clinical nutritionist and author of 2019’s The Collagen Diet, who notes that production of the multitasking amino-acid chains starts to decline around age 25. “By the time you’re in your mid-50s, your body is producing 50 percent less collagen,” Axe continues. The way to help replenish those reserves, he says, is to consume it—whether by simmering bones into a savory stock (à la Marco Canora’s celebrity-favorite Brodo) or reaching for the new and best collagen supplements now flooding the market. Read on to learn everything you need to know about collagen supplements—from hair, skin, and nails benefits to the best products shop.

“Collagen is a structural protein, rich in amino acids, abundantly found in the body,” nutritionist Dr. Charles Passler tells Vogue. “Skin, cartilage, bones, connective tissue, and tendons use collagen for structural support.

True collagen supplements are made from animal or fish proteins and contain short chain amino acids, peptides.” Promising everything from thicker hair and stronger nails to plumper skin, collagen powders are on track to reach $7.5 billion by 2027, Business Insider previously reported. The sector is led by brands such as the Chicago-based Vital Proteins, which became Instagram-famous when it partnered with Kourtney Kardashian on an organic blueberry-and-lemon–flavored powder sourced from pasture-raised cows in Brazil.

What are collagen supplements actually supposed to do for the body? To get the scoop (pun intended), we’ve tapped Valerie Agyeman, a dietitian and host of women’s health podcast Flourish Heights, who shares all the purported benefits—from healthier hair and stronger nails to improved muscle mass. A breakdown, below:

• Youthful-looking skin: “Collagen supplementation may help improve skin elasticity and hydration by supporting the body's natural collagen production, but there are many factors when it comes to the overall health of your skin, therefore a collagen supplement may not be a quick fix to keeping that skin feeling and looking youthful,” she explains.
• Stronger nails: “Anecdotally, some individuals have reported that collagen supplementation strengthened their nails, reducing brittleness and breakage,” Agyeman says. “The research is mixed but it may potentially support nail growth and overall nail health by providing essential amino acids.”
• Improved muscle mass: “Collagen plays a role in muscle structure and function, aiding in muscle repair and growth,” she notes. “Supplementing with collagen if needed may support muscle mass maintenance, which can be beneficial if you are highly active.”
• Improved cardiovascular health: “Some research suggests it may indirectly benefit cardiovascular health by reducing arterial stiffness,” says Agyeman. “However, more studies are needed to fully understand collagen’s impact on cardiovascular health.”
• Better sleep: “The research on the calming effects of glycine, an amino acid found in collagen, and its potential to improve sleep quality is mixed, some individuals claim it made them fall asleep quickly or stay asleep for longer,” she explains.

“The most important thing when choosing a supplement, is making sure the supplement doesn’t contain any unnecessary additives and fillers,” Passler says. “Multiple types of collagen exist and each has a specific function in the body. I prefer a supplement that has more than one type of collagen and is made to be easily absorbed.”

• Types of Collagen: There are 28 types of collagen overall, but five main ones to look out for. For cosmetic benefits (i.e: youthful, glowing skin) look for Type I, which is what impacts the skin, bones, and ligaments. Type II is found in cartilage, so this is beneficial to support joint health. Type III is found in the muscles and organs, and works in tandem with Type I to support skin health.
• Form: You’ll notice that collagen supplements vary in form—think powders, capsules, and liquids. Choose which works for you based on your diet, activities, and general supplement preferences.
• Third-Party Testing: Because the FDA does not regulate collagen supplements in the U.S., you may want to find something that has been third-party tested; this means the supplement’s ingredients have been evaluated by a third-party, and can stand up to its claims.

This is not to say that the results are immediate. “Do you ingest collagen and look in the mirror and give yourself a thumbs-up? No, it doesn’t work like that,” admits Bobbi Brown, the beauty mogul and founder of wellness brand Evolution_18, whose collagen-based offerings were carried at Walmart. But real, perceptible benefits can often be achieved in a few months, Brown is quick to add. Passler says that those who experience joint and muscle pain can see results faster than those interested in the aforementioned cosmetics benefits. Overall, expect at least six weeks to see—and feel—a difference.

“Inside-out beauty is more important than ever,” agrees One Ocean Beauty’s Marcella Cacci, who launched her marine-based skin-care line in 2018 with a five-piece lineup, which includes complexion-boosting collagen supplements that deploy skin-healthy vitamins found in tomatoes and pomegranate extract. Similarly, this inside-out approach led Kate Hudson to develop what she calls her “dream product”—the InBloom Beauty Aura that she indulges in each morning, a step she revealed in her installment of Vogue’s Beauty Secrets.

It’s certainly an appealing premise—if not entirely in line with our increasingly plant-oriented diets. “It’s almost impossible to find the quality of the collagen you are using or exactly where it came from,” Brooke Russell, Ph.D., a vice president of operations at ECM Biosurgery, says of the powders, which are sourced from the bones, skin, or connective tissue of animals like cows or fish. “Most of the time, you don’t really know what is in there.” New York City-based dermatologist Pat Wexler, M.D., isn’t entirely sold either. “There are no negative side effects—but there is a lot more research to be done,” says Wexler, cautioning that many of the studies have been paid for by the companies producing the supplements.

Generally speaking, research suggests that 2.5 to 15 grams of collagen per day is suitable for the American diet. Passler caveats this by stating that those prone to kidney oxalate stones should avoid over 10 grams of collagen per day. (This is the only instance in which someone could take too much collagen.) In any case, it’s best to stick to the serving size of your chosen supplement and, as always, consult your trusted health service provider.

“Collagen is broken down, absorbed in the gut, and used as building blocks for the listed expected benefits. Incorporating a high quality collagen supplement, in addition to a healthy diet and lifestyle, is a great way to look and feel your best.”
