Why 5g of our collagen is enough+
Many collagen brands rely on 10g+ serving sizes with fillers for higher volume. Our highly bioavailable collagen peptides have been clinically studied from 2.5g, so we include 5g per serving— twice the clinically studied amount, without unnecessary bulk.
Limited Edition+
Our Watermelon Juice is a limited-edition summer flavor, crafted to be enjoyed during the hottest months of the year. Once this seasonal batch sells out, we can't guarantee when— or if— it will return, so grab yours while it's here.

More than a pretty juice
Collagen is the main protein that gives your skin its structure and strength. Drinking it daily is clinically researched to support your body's natural collagen production — leaving skin firmer, more hydrated, and visibly smoother with fewer fine lines.
Skin Firmness & Elasticity
Supports the natural collagen production that keeps skin firm, plump, and resilient — especially after 25, when production slows.
Hydration From Within
+28% measured skin hydration over 30 days of daily use — the kind of glow you can see, not just feel.
Hair, Lash & Brow Strength
Supports fuller-looking hair, stronger nails, and better-looking lashes and brows over time.
Joints & Gut Support
Beyond beauty: supports joint strength, gut lining, and bowel regularity. A quiet wellness upgrade.
Beauty Sleep
Did you know that glycine — one of the primary amino acids in collagen — is associated with deeper, more restorative sleep? Wake up to better skin and better-looking hair, gradually but unmistakably.
100%
increase in skin firmness for the look of fewer wrinkles*
Small, but Mighty
Never Junky Collagen
We hydrolyze our collagen into ultra-fine peptides with no fillers or unnecessary additives, delivering 2× the clinically proven effective dose in every serving—so you get maximum efficacy without oversized servings or wasted ingredients.
Less is More
Most collagen brands need 10g per serving to achieve results. Thanks to our ultra-pure, highly bioavailable collagen peptides, clinical research has shown effectiveness at just 2.5g.

Did You Know?
After 25, you lose about 1% of your collagen every single year.
That's the firmness, bounce and glow slowly slipping. The good news: drinking it back is the easy part when it tastes like banana milk.
To replenish your body’s natural collagen decline, you need the right amino acids—delivered in a low Dalton size that’s easy for the body to digest and use.
