If you think collagen is just a fancy wellness buzzword, think again. Collagen is the most abundant protein naturally found within your body; it's essentially the substance that holds your body together. That connective tissue that makes up your muscles, ligaments, bones, tendons, and skin barrier? Yup, it's mainly collagen. Collagen is also what gives youthful skin that desirable bounce and glow (hence collagen-laden creams). But natural collagen production levels decrease as we age, contributing to dry skin, fine lines, sagging, and wrinkles, not to mention sore joints. Enter: Collagen powder.

How does collagen powder work?

Collagen powders are made from animal (typically bovine or marine) or plant tissues that have been processed and hydrolyzed into peptides to allow for easy absorption. Collagen studies have shown that regular and long-term intake of collagen in powder or supplement form can help curb signs of aging, as well as strengthen bones and make wounds heal faster. 

With consistent use, you're likely to see better skin elasticity but also less joint pain as well as stronger hair and nails. (One important note: Side effects from collagen powder and supplements are rare but possible—and present most commonly as digestive problems—so stop taking collagen if you experience anything unusual.)

Ahead, our favorite collagen powders of 2022.
