Sweet Cream Soda Collagen

Meet the cream soda you grew up loving— but upgraded with collagen and with fraction of the sugar. Our nostalgic twist on your collagen ritual— this dreamy blend captures the sweet, fizzy magic of Korean cream soda with a delicate touch of coconut.

Just mix it with sparkling water to recreate the iconic “Milkiss” soda we all loved growing up— only now, it’s supercharged with beauty-boosting marine collagen to help you glow from the inside out. Creamy, sweet (with fraction of the sugar of normal soda pops), and refreshingly light, it’s your childhood favorite reimagined with functional benefits.

Sweet, creamy and fizzy in sparkling water, like "milkiss" soda.

Why Banana Milk

"I couldn't find a collagen that delivered on both taste and quality. So I created delicious flavors around premium, highly hydrolyzed collagen peptides— because your daily skincare ritual should be something you genuinely enjoy."

A beauty drink

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.

The Science, Minus the Snooze

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.

  • Actually 3rd Party Tested

    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.

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.
