These Collagen Powders Improve Skin, Nails, and Joints With One Daily Scoop

Collagen isn’t just the body’s most abundant protein—it’s the biggest wellness supplement on the market. Slathered on in wrinkle creams, popped in capsule form, sprinkled into nutrition bars, it’s everywhere—and collagen powders, in particular, are the increasingly popular and versatile way to get it in.

Think of collagen as a strong, flexible glue. It helps hold together tissues like skin, muscles, bones, ligaments, tendons, cartilage, blood vessels, and cornea, explains Rachel Jones, M.S., R.D.N., chief nutrition officer at GNC. And with the help of protein-rich foods like fish, poultry, meat, soy, and legumes, the body produces it naturally. However, that production slows with age and can be compounded by habits like smoking, drinking alcohol, and lack of sleep and exercise, according to Harvard’s T.H. Chan School of Public Health.

In turn, research shows that collagen supplements (derived from that of animals including fish, chicken, and bovine) may keep levels optimal while also promoting skin elasticity, bone health, muscle strength, and joint flexibility. However, further research is needed to determine its bioavailability (a.k.a. how well it’s actually absorbed) in supplement form, adds Amy Lee M.D., chief medical officer of Lindora L.L.C. and head of nutrition at Nucific.

Still, the existing evidence shows enough promise to get most wellness enthusiasts on board—plus, scooping a flavorless, finely milled powder into a morning smoothie makes it pretty easy to try. If you’re curious about adding one to your morning routine—just keep scrolling.
