I’ve been taking this collagen for years because without it I have bad neck and back pain. When taking collagen regularly (one scoop every morning in my coffee) I feel so much better. I also love that this is a source of protein. Wonderful product!

Excellent product! The quality is great, and it really works — dissolves very well and gives me energy every day. For the past few years, I’ve only used WithinUs collagen, but the combination with creatine is a real game changer. On top of that, the delivery was super fast. Highly recommend!

I have taken this one for about 2 years, before that I was taking another brand and it wasn’t good. It was hard to dissolve in your beverages. Didn’t feel and results. I started taking to help with my ankles which always ache. My ankles are better , but my hair is so much nicer and grows so much quicker now. I have a subscription every two months I receive the 100 serving size.

We Were First. We Stayed True.

withinUs was the first to bring premium marine collagen to North America. From the beginning, we committed to sourcing the highest-quality ingredients because we never believed in doing things any other way.

We knew others would follow, and they did. But competition was never going to change who we are, what we stand for, or the standards we set for ourselves.

It still doesn't.
