8. Best for Skin: Revive Collagen Enhanced Plus

This travel-friendly collagen option is a favorite of Ariana Yaptangco, Glamour senior beauty editor. “Since I started taking this marine collagen supplement, I’ve noticed my hair looks shinier and my nails feel stronger. Jury’s out on whether or not it’s because of my new haircut or the fact that I’m taking an break from gel manicures, but something tells me it’s a little bit of both. In addition to collagen, these sachets include essential vitamins like vitamin B6, B12, C, and D3 to support overall health. Think of it as killing two birds with one stone.
