Marine Collagen Peptides Pro | Unflavored
Collagen synthesis declines 1-1.5% per year starting in your early 20s. Type I collagen — the type marine peptides deliver — makes up 90% of skin, tendon, and bone structural protein.
The Proksch RCT (2014) showed 20% improved skin elasticity at 8 weeks with 2.5g/day marine collagen peptides. This formulation delivers the clinically-effective dose in an unflavored, easy-to-mix form.

What's NOT in this formula
No fillers. No artificial colors. No proprietary blends hiding underdosed ingredients. No GMOs. No gluten, soy, dairy.
Every ingredient is disclosed at its exact dose — the same dose used in the published clinical trials our research cites.
Rebuild from within — one clean scoop at a time.
You move through the world with intention. Your joints carry your ambitions, your skin tells your story, and your gut quietly drives everything. Marine Collagen Peptides Pro is formulated for those who refuse to let time outpace them — delivering the structural protein your body once made effortlessly, now when it needs it most.
Sourced from wild-caught, deep-sea fish, our hydrolyzed Type I collagen peptides are broken down to a low molecular weight for superior absorption. Once absorbed, these bioactive peptides signal fibroblast cells to ramp up the body's own collagen synthesis — supporting skin elasticity, joint cushioning, and intestinal wall integrity at the cellular level.
Designed for the longevity-focused individual aged 40 and beyond — the biohacker, the active professional, the person who reads labels and demands answers. If you stack your protocols thoughtfully and expect your supplements to earn their place, this is yours.
Why we made it
- Deep-sea purity — wild-caught, sustainably sourced with no fillers, flavors, or additives
- Superior bioavailability — hydrolyzed to under 5 kDa for rapid gut absorption and cellular delivery
- Joint & skin resilience — clinically studied peptide sequences shown to support collagen synthesis and elasticity
- Effortless integration — unflavored, dissolves fully in hot or cold liquids with zero taste or texture
What's in it
- Hydrolyzed Marine Collagen Peptides (Type I) — 10g per serving: Derived from wild-caught deep-sea fish skin. Low molecular weight (~2–5 kDa) ensures efficient intestinal absorption. Type I collagen is the most abundant collagen in human skin, tendons, ligaments, and bone matrix.
- Hydroxyproline-rich Dipeptides (Pro-Hyp, Hyp-Gly): The specific bioactive sequences released during hydrolysis. Research indicates these peptides stimulate dermal fibroblasts and chondrocytes, directly upregulating the body's endogenous collagen production.
- Glycine (naturally occurring, ~2g per serving): The dominant amino acid in collagen. Supports gut lining integrity, liver detoxification pathways, and neurotransmitter balance — contributing to the broader longevity profile of this formula.
How to use
Mix one scoop (10g) into 8–12 oz of your preferred hot or cold beverage daily, ideally with a vitamin C source to support collagen synthesis.
Common questions
Why marine collagen over bovine?
Marine collagen is predominantly Type I — the same type that dominates human skin, tendons, and bone — and its smaller peptide size gives it a measurable absorption advantage over bovine sources in peer-reviewed comparative studies. For skin and joint-focused protocols, it is the more targeted choice.
How long before I notice results?
Most clinical trials on hydrolyzed collagen peptides show measurable changes in skin elasticity and joint comfort markers between 8 and 12 weeks of consistent daily use. Collagen remodeling is a slow biological process — think of this as infrastructure investment, not a quick fix.
Is this product third-party tested?
Yes. Every batch of Marine Collagen Peptides Pro is tested by an independent ISO-certified laboratory for heavy metals, microbial contaminants, and label-claim accuracy. Certificates of Analysis are available on request. Clean label is not a marketing claim here — it is a production standard.
Where this comes from, what we test for
Radical transparency is the only way to translate the published trial literature into a buying decision. Below: the form, the trial-validated dose equivalence, the production method, and the QC tests on this batch.
Hydrolyzed Marine Collagen · 10 g per serving
Source: wild-caught North Atlantic fish skin (not farmed, not tilapia). Hydrolyzed via enzymatic process to peptides in the 2–5 kDa molecular weight range — the size that crosses the gut barrier intact and reaches dermal and connective tissue. Dose: 10 g daily, the lower bound of the 10–20 g range used in the König et al. 2018 skin elasticity trial and the Zdzieblik et al. 2017 joint comfort work.
Amino acid profile
High in glycine (~22 percent), proline (~13 percent), and hydroxyproline (~10 percent) — the three amino acids endogenous collagen synthesis is most rate-limited by. The amino acid signature is not matchable by whey, casein, or plant protein isolates.
What we test for
Heavy metals below USP <232> limits — critical for any marine-sourced ingredient given ocean contamination baseline. Microbiology per USP <2021>/<2022>. Identity confirmed via amino acid profile match to type I collagen reference. Unflavored — no maltodextrin, no artificial sweeteners, no fillers.
Try it for 90 days. If you don't feel the difference, we'll refund every cent.
Cellular-level benefits take 60–90 days to compound. A 30-day window isn't honest — so we built our guarantee around the science. Give the protocol the time the research actually requires, and judge it on real results.
