Banana Milk Collagen
Tastes like a frosty banana milkshake
By your mid-20s, natural collagen production starts to slow — and your skin, hair, and nails show it first. Quality collagen can help support those changes — but most powders are chalky, poorly absorbed, and full of fillers.
Ours is different. We worked with Korean flavor scientists to create a collagen drink that tastes like nostalgic banana milk — smooth, creamy, and actually enjoyable — with clinically backed benefits for skin and hair.
Halal and kosher certified, zero artificial coloring, lab-tested, sustainably sourced, and engineered for maximum absorption.
Now available in low-sugar and zero-sugar options, with your choice of marine collagen, bovine collagen, or our vegetarian glycine formula.

Marine vs. Bovine?+
Marine is Type I only with slightly smaller peptides. Bovine contains Type I and III for broader-spectrum skin, joint, and gut benefits. Both hydrolyzed to 4,000 Daltons.
Why this collagen actually works+
Hydrolyzed to 4,000 Daltons — small enough to absorb directly through the gut lining. Third-party tested for heavy metals. Zero fillers or binders.
Clean ingredients+
Halal and Kosher certified. No artificial coloring or flavoring. Sterilized and filtered twice. Truly flavorless.
Full amino acid profile+
Hydroxyproline, Methionine, Arginine, Lysine, Histidine, plus Proline, Leucine and Glycine.

바나나 우유 · authentic Korean banana milk flavor, made in Korea
Why Banana Milk
“I'm Korean. Banana milk is the taste of my childhood — so I had the flavor made in Korea, the way it's supposed to taste, and built it around collagen that actually absorbs. Not a supplement you choke down. Skincare you look forward to.”
— Sally, Founder of Crushed Tonic
Why Korea
The country that perfected skincare.
01
Korea leads skin
The world already trusts Korea with its skin — it's to skincare what France is to wine.
02
A Korean founder
Sally grew up with these flavors and this beauty culture. Lived, not researched.
03
Flavors made in Korea
The banana milk tastes authentic because the flavor itself is made in Korea.
04
Skincare you drink
So this isn't another supplement — it's inner beauty, in a glass you crave.

Tiny peptides, big glow.

It actually shows up
We hydrolyze our collagen into tiny peptides that slip through the gut wall instead of getting wasted — so more of it reaches your skin.
⚡
No waiting around
At 4,000 Daltons, these peptides absorb fast — roughly double what a lot of collagens manage.

Glow you can see
Better absorption means real payoff — skin, hair, nails. +28% hydration in 30 days, clinically proven.

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.
