What Exactly Are the Benefits of Collagen Pills? Two Experts Weigh In

"Collagen is the most abundant protein in the body, making up about a quarter of our weight," Jennifer Herrmann, a Beverly Hills dermatologist at MFC Dermatology, says. "It's considered the key structural component of bone, blood vessels, cartilage, tendons, and skin."

Considering how pervasive—and vital—collagen is to our overall health, it's not something that usually garners much interest. Instead, it's easier to notice what happens when collagen production lessens. We complain about the lines circling our eyes and lips, the small folds that appear above our eyebrows and below our necks, and the brittleness of our hair and nails. This transformation can start as early as our 20s, so it's especially important to get a handle on this protein's longevity as soon as possible.

While the most straightforward solution for boosting collagen in the body can be found in a diet that contains adequate protein, it's also not uncommon to take collagen pills to help, too. "Ingestible collagen bolsters the body's natural production by being absorbed through the bloodstream and reaching the underlying layers first, offering a longer-term solution," says Fern Olivia, founder of Thyroid Yoga.

Herrmann and Olivia agree that if you're eating enough protein, then you probably won't see any other results by also taking collagen pills. But if you are curious about how collagen pills work, we asked both women to describe their benefits and potential issues when taken regularly. Olivia also recommended her favorites, in case you're looking to give this trend a try.
