Marine vs. Bovine?+
Marine: Type I collagen with smaller peptides for skin-focused benefits.
Bovine: Type I & III collagen for comprehensive support of skin, joints, and gut health.
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.

Why Banana Milk

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

— Sally, Founder of Crushed Tonic
UPGRADE YOUR DAILY COFFEE

Your latte just became skincare.

Creamy Korean banana milk, sweetened with allulose for the same rich, nostalgic flavor— without ton of sugar.

Skip the powdered creamers full of fillers
Get rich, creamy banana milk flavor while adding 5g of premium marine collagen to every cup.
Sweet without artificial sweetener
Instead of heavy creamers loaded with artificial sweeteners, oils, gums, and empty calories, stir in our low-sugar banana milk or 0-sugar, 0-calorie allulose-based banana milk (naturally derived from fruits).
Identical taste
Sugar-free banana milk leaves a slight cooling sensation and a slightly lighter flavor, but the creamy Korean banana milk taste is still very much there. Most people can barely tell the difference.

The latte that loves your skin back.

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.
Collagen for Beauty Sleep
Dd you know that glycine — one of the primary amino acids in collagen — is associated with deeper, more restorative sleep? Drinking collagen as a wind-down latte and let your body do the rest. Wake up to better skin and better hair.

“” Most asked

0-sugar v low sugar?

0g

Low-sugar is sweetened with 3g of cane sugar, while 0-sugar is sweetened with allulose — but the taste is identical. Same creamy, lightly-sweet taste you already love. You'd never guess the sugar is gone.

Taste test

Real reactions to the sugar-free sip — see for yourself.

Why Allulose?

Not a fake sugar. Naturally rare one.

Allulose is a real sugar — the kind that shows up in tiny amounts in figs, raisins and maple syrup. Your tongue reads it as sweet, but your body barely uses it for energy. So you get true sugar taste at virtually zero calories, with no chalky, chemical aftertaste.

What it is

  • A real, naturally-occurring rare sugar
  • Found in figs, raisins, maple syrup & jackfruit
  • Tastes like sugar — clean, no aftertaste
  • Passes through without feeding you calories

What it isn't

  • Not aspartame, sucralose or saccharin
  • Not a lab-made artificial sweetener
  • Not a sugar alcohol like erythritol
  • Not the metallic aftertaste you're bracing for

Straight from nature's pantry

The same rare sugar your favorite whole foods already carry.

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.

FAQ

Does the sugar-free version taste as good as the low-sugar one?+
Yes! It’s almost identical. Since it’s sweetened with allulose instead of sugar, you may notice a very slight cooling sensation and a slightly lighter flavor, but the creamy Korean banana milk taste is still very much there. Most people can barely tell the difference.

I’m diabetic. Which banana milk should I choose?+
Our Banana Milk is already low in sugar, but if you're looking for a completely sugar-free option, try our Sugar-Free Marine Collagen or Sugar-Free Glycine. Both are sweetened with allulose, delivering the same creamy Korean banana milk flavor without the sugar.
Amount and serving size?+
1 sachet (14g) per day. Each box has 30 servings. We deliver 10g per sachet.
Marine vs Bovine?+
Marine is Type I only. Bovine is Type I and III. Both hydrolyzed to 4,000 Daltons.
Why should I trust your collagen?+
Every batch is third-party tested by an ISO-certified lab for heavy metals, pesticides, and contaminants.
How long to see results?+
Skin hydration from week 4. Visible glow weeks 6-8. Full dermal remodeling: 90+ days.
Can I take it if pregnant?+
Generally considered safe, but always consult your healthcare provider first.
How is it sustainably sourced?+
Wild-caught fish and grass-fed bovine with full traceability.
What is the clinically proven dosage?+
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. We still include 5g in every sachet—that's 2× the clinically proven effective dose—so you get exceptional efficacy without unnecessary fillers or oversized servings.
