"If it's easy, I'll stick with it. I throw this in my coffee every morning and don't have to think twice about it."

People usually take it for:

  • Supporting skin elasticity and hydration
  • Joint comfort, which has its own separate research

This one couldn't be easier. I stir it into my morning coffee and move on with my day. Some research says collagen may help skin stay firm and hydrated, and may help achy joints, when you take it every day.

Why I like it: It's the easiest habit in my whole routine, and easy habits are the ones I keep.

Does collagen actually work for skin?

A 2023 review pulled together 26 studies with 1,721 people. Collagen helped skin hold more water and stay more stretchy, compared with a fake pill, and how long people took it changed the results. Good to know before you buy: another review found the stretchy-skin results showed up in studies paid for by companies, and didn't show up in the independent ones. Bigger independent studies are still needed. The 2023 review of 26 studies → Other studies have looked at collagen for knee pain from arthritis. The knee pain review →
