What is Collagen?

In 2020, in the United States alone, consumers are expected to spend $293 million on collagen supplements, up from just $50 million in 2014, according to market research firm Nutrition Business Journal.

Collagen is often called the body’s scaffolding.

“It’s the glue that holds the body together,” says New York dermatologist Whitney Bowe, author of The Beauty of Dirty Skin: The Surprising Science of Looking and Feeling Radiant from the Inside Out.

“As we get older, we break it down faster than we can replace it,” she says, noting that we begin to lose about 1% of our collagen per year in our mid-20s and lose as much as 30% during the first 5 years of menopause.

And a 2019 review of eight studies including 805 patients concluded that “preliminary results are promising for the short and long-term use of oral collagen supplements for wound healing and skin aging.”

NOT ALL COLLAGEN CREATED EQUAL

Since collagen is a supplement, it is not regulated. Best collagen powder is derived from free-range, cage-free, grass-fed, antibiotic-free animal sources.

My recommendation is to get collagen supplement that was manufactured outside of US.
