Key benefits for your daily routine
Give your body the building blocks it needs with Youtheory® Advanced Collagen. Each serving delivers a generous 6,000 mg of hydrolysed collagen peptides, plus vitamin C to help maintain your skin, bones, and connective tissues—so you can feel your best, inside and out.
Collagen is a key protein found throughout your body, but natural levels decline as we age. This formula is designed to help you stay on top of your daily wellbeing, with vitamin C contributing to normal collagen formation for the healthy function of skin, bones, cartilage, gums, teeth, and blood vessels.
Youtheory’s collagen is produced using a natural cold-enzyme process, resulting in pure, low-molecular-weight peptides for easy absorption. Sourced from trusted farms in France, Brazil, and the USA, every batch is made in their Southern California facility to ensure quality from start to finish.
Founded in 2010 by Darren and Patty Rude, Youtheory has grown from a collagen specialist to a leading name in science-backed supplements. Their mission is rooted in integrity and quality, with a commitment to sourcing pure ingredients, rigorous testing, and giving back to communities worldwide.
At Healf, we carefully select every product through our three-step process: Discovery, Expert Validation, and Community Testing. So you can shop with confidence, every time.

I definitely see a difference in my nails. My nails used to break all the time and now they are growing stronger by the day.
Good collagen . I will purchase again!

I have been taking this collagen for a number of years. My hair and nails grow fast. Also, my skin is super soft without have to moisturize it. I love this collagen.
