- Every batch tested for heavy metals. No added sugar, artificial colors or fillers.
“If we can’t explain why an ingredient is in there, it isn’t.”— The founders of UNDONE
I’d tried three collagen powders before this and never stuck with any of them. Too sweet, or clumpy in coffee. Someone in a perimenopause group mentioned UNDONE's Collagen Foundation as the all-in-one formula that works for them, so I gave it a go. One scoop goes straight into my morning coffee and dissolves completely. 9 weeks in, my skin doesn’t feel tight and dry by the afternoon anymore, and I’m lifting heavier than I was in spring. It’s the first supplement I haven’t forgotten about.142 reactions

Why women choose Collagen Foundation
We stripped it back to what works, and we print all of it on the label.
What women are saying
Four things to look for in your first 12 weeks*
Once your body has the foundation, it shows up in everyday moments. Here’s what the ingredients are there to support.
Skin that holds hydration
Collagen peptides plus vitamin C support skin elasticity and hydration, the two areas the research looks at most.
Strength you can feel
Creatine at the amount used in studies supports muscle strength, alongside resistance training.
Recovery that keeps pace
Magnesium bisglycinate supports normal muscle function and energy metabolism, so consistency feels easier.
Moving the way you like
Collagen peptides also support joints and connective tissue as part of an active life.

The research behind the formula
Why these four ingredients, at these amounts? Each one earns its place because published studies support it, and the amounts follow what those studies used. More is not better. The right amount is.

Unlike a collagen-only powder, Collagen Foundation supports you from the inside out.
Collagen peptides are the building block. Vitamin C is what your body needs to turn them into its own collagen.
Creatine supports the muscle building, and magnesium supports the recovery. All-in-one formula for feeling like yourself every day.
Collagen declines every year after 25

A daily foundation for the way you want to age: strong, active, and well.

One simple habit can do so much.
No capsules to count, no five-bottle routine. One scoop in the drink you already make.
What most women can expect, week by week
Consistency is the whole plan. Here is how the ingredients work over twelve weeks.
Building the habit
One scoop becomes part of your morning. Magnesium supports normal muscle function while your routine settles in.
Creatine fills up
With daily use, creatine stores in muscle build up. This is when strength support becomes most relevant to your routine.
Structure and support
Collagen turnover is gradual. Daily intake with vitamin C keeps supporting your body’s own collagen formation.
The foundation is set
Twelve weeks is one full cycle, which is why we built the 12-Week Ritual. This is the point to judge how it fits your life.

One formula, built on what the research supports.
Aging well starts on the inside.
