People are drinking collagen powder for its anti-aging benefits, but how safe is it?

“Collagen is a structural protein made up of amino acids that’s found naturally in the connective tissue of our bodies, such as our skin, hair, muscles, bones and even blood vessels,” Keri Gans, registered dietitian nutritionist and author of The Small Change Diet, tells Yahoo Lifestyle. “It is essentially the ‘glue’ that holds our body together, enables us to move and find stability.”

Adds Joshua Zeichner, MD, director of cosmetic and clinical research in Mount Sinai Hospital’s department of dermatology, “Collagen is the main protein in our skin that provides structure and support.”

And it’s that structure and support that plays a role in keeping skin looking smooth, firm, and wrinkle-free.

But collagen production slows down as we age, which is why many people are turning to consuming collagen peptides (also known as hydrolyzed collagen) in the hopes that the supplements will reverse or at least stave off skin aging.

“The hope for ingestible collagen is that it helps strengthen our skin to improve the appearance of fine lines and wrinkles, as well as enhance skin texture,” Zeichner tells Yahoo Lifestyle.

But does consuming collagen powder actually do anything?  Possibly.

The true benefit of ingestible collagen is unclear, Since collagen is a large molecule, it is broken down by our gut into smaller pieces. The smaller pieces and individual amino acids may serve as building blocks for new collagen production.

Many individuals believe the numerous health claims in regards to collagen. There are claims that it can reduce constipation, improve gut health, improve sleep, decrease anxiety, reduce joint pain, eliminate food cravings and has anti-aging properties.

What are the benefits?

Although more research is needed, there are some studies that have looked into collagen supplements’ potential benefits   particularly for easing joint pain and help reduce joint deterioration in athletes.

It may also help with brittle, fragile nails. A small 2017 study in the Journal of Cosmetic Dermatology found that consuming collagen peptides daily for 24 weeks helped prevent nail breakage, increase nail growth, and improved the appearance of brittle nails.

How safe is it?

The only harm is to your pocketbook, as many of the collagen powders are pricey. However, it’s important to read up on the source of the supplement’s main ingredient. The collagen found in supplements is typically sourced from cow (bovine) hides, as well as chicken cartilage, but in some cases they can be made from fish or eggs, which can be dangerous for people with those food allergies.

As with any supplement, one should read the label closely to make sure it doesn’t include any allergens that they are sensitive to, also, if on any medications a person should discuss with their doctor or a registered dietitian before implementing in their daily diet.
