The 9 Best Collagen Supplements, According to Dietitians

ishonest / Chloe Jeong

Collagen is ingredient, but it can have real benefits. “Collagen is a structural protein known to support your skin, bones, muscles, tendons, and ligaments,” says Breanna Woods, MS, RD, a dietitian based in Indianapolis. “As we age, our body naturally produces less collagen. Research supports that taking a collagen supplement may improve joint mobility, skin integrity, and muscle strength (when combined with resistance training).” Plus, a study in Nutrition Journal found that collagen supplementation helped improve symptoms of osteoarthritis, too.

As far as the beauty industry is concerned, though, you may be hearing more about collagen supplements for their skincare benefits—some research has shown that taking a collagen supplement can help improve skin hydration, elasticity, roughness, and density.

To get the scoop on the best collagen supplements out there, we asked nutrition experts for their top picks. Note, though, that you don’t need supplements if you’re getting collagen from food sources. “As always, the priority should be to get nutrition from food,” notes Woods. “Although collagen may have benefits, supplements are expensive and not totally necessary.”

What to Look For in a Collagen Supplement

Hydrolyzed collagen

Samuels recommends looking for supplements that are formulated with hydrolyzed collagen, which indicates that it’s easier to digest and is more quickly absorbed after ingestion.

“It’s also high in the amino acids glycine and proline which are essential for building new collagen in your muscles, bones, and gut,” she adds.

Grass-fed, pasture-raised, and antibiotic-free

When shopping for a collagen supplement, Samuels also stresses the importance of choosing a product that’s made from grass-fed, pasture-raised, and antibiotic- free animals to ensure you’re ingesting the healthiest collagen possible. “The collagen shouldn’t contain any additives or fillers,” she says. “Dietary products are not regulated by the FDA, so it’s important to be mindful of the source of your ingredients to avoid excessive exposure to antibiotics, pesticides, and other potentially harmful substances."

Third-party verification

Samuels also recommends looking for products with third-party verification to ensure that the product lives up to its claims and contains the ingredients it says it does. “These companies also ensure there aren’t any additional ingredients in the product that aren’t listed on the label,” she says. She suggests looking for verifications by the following credible groups: NSF International, UL, and US Pharmacopeia.

As with any supplement, check with your doctor before taking one, but if you get the thumbs up, here are the best collagen supplements out there.

Here’s the perfect product for a pescatarian who doesn’t want to consume bovine collagen. “There are many different types of collagen on the market, however, there is a huge difference between bovine and marine collagen,” says Cynthia Barrett, PT, DPT, founder of Wellness Couture in New York City. “Indigo Marine Collagen is fished in the wild and processed in the United States to ensure strict quality controls. It also consists of smaller peptides or smaller protein molecules than bovine collagen sources, which means it’s more efficient in the body.” The product contains Types I, II, III, and IV of collagen.

Final Verdict

There are many collagen supplements on the market right now, but our favorite is Ancient Nutrition's Multi Collagen Peptides Protein Powder Pure. Additionally, marine collagen products are available for people who do not want to consume bovine collagen—if that's you, opt for Indigo Marine Collagen Pure.

“Emerging research using nutritional supplements containing hydrolyzed collagen is beginning to show additional anti-aging, collagen-boosting promise in the skin,” says Joan Salge Blake, EdD, RDN, a nutrition professor at Boston University and host of the podcast Spot On! Additionally, research using Verisol shows a decrease in the wrinkles that appear around your eyes.

Yes. However, according to Woods, most collagen supplements have a pretty long shelf life. “Even after the expiration date, the dry nature of powders means they don't technically spoil or become unsafe to eat," she says. "However, the quality of the collagen will likely decrease, which may impact its effectiveness.”

“Consistency is key for results,” says Woods, who recommends taking one serving per day. “A lot of people like mixing it in their coffee, smoothie, but you can add it to any beverage. You can also add it to oatmeal or baked goods. However, it's not necessary to take collagen with food.”
