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.
Bovine: Type I & III collagen for comprehensive support of skin, joints, and gut health.
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.
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.

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.

FAQ
Can collagen help with acne?+
Yes - collagen peptides support the skin barrier and reduce inflammation, which can positively impact acne-prone skin.
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.
