At this point, collagen has spent a decent amount of time as a buzzword in the beauty space, accepted by many people as an additive that will improve skin .

Collagen makes up one-third of the protein in the human body, according to research, and weve gotten used to the idea of people using collagen fillers at the dermatologists office.

But now that collagen supplements have hit the map, companies like Vital Proteins offer collagen powders that can be added to water, lattes, baked goods and more, supposedly benefiting hair, skin and nails , and aiding the health of joints and ligaments .

The idea behind the suddenly trendy product is that you get access to amino acids, which come into your bloodstream and then your body can create its own collagen, said nutritionist Julie Rothenberg of Floridas JuliENERGYnutrition.

Health and fitness influencers on social media, like Lara Dominianni (@_littlemissfoodie ), Atilla Toth (@atilla ), Kaitlyn Bristowe of The Bachelorette, and Kourtney Kardashian, who partnered with Vital Proteins for her Pink Moon Milk Collagen Latte, have touted the effectiveness of the brands collagen powders.
