These days, we don’t just want to feel OK. We want to feel absolutely, positively amazing—and look the part, too.

Aging gracefully depends on how you nurture your body. Today, a trove of studies shows the importance of following a nutrient-dense diet, being active and taking dietary supplements to support a healthy aging process. One of the clear standouts to help along the way: collagen, an antiaging nutrient that rose to stardom in Japan decades ago and now is making its prowess known here in the United States, thanks to innovative, research-backed products and an understanding that what goes inside your body supports your skin, hair and nails.

“In Asia, collagen supplements have long been a craze, and even before [collagen supplements], the tradition of consuming certain foods to rejuvenate the complexion is an old one,” says Naomi Whittel, founder of Reserveage Nutrition. “Asian diets are rich in collagen from foods like homemade bone broth from skin-on, bone-in chicken.”

Found plentifully just about everywhere in our bodies—from our skin, hair and nails to our bones and joints—collagen is an important protein for staving off wrinkles and keeping our joints healthy. The problem? As we age, we start to lose it. A notable decline in your collagen production starts at age 25, which means relying on your body’s stores simply isn’t enough.
