Why this product
Collagen production declines every year after 25. Daily supplementation has measurable effects.
Hydrolyzed collagen peptides — unlike whole collagen — are broken into small peptides that pass through the gut wall intact and enter the bloodstream. Once circulating, hydroxyproline-containing dipeptides directly signal fibroblast cells to produce new collagen. This mechanism is well documented across multiple clinical studies. mCollagen provides the peptides in their correct ratios, from a clean grass-fed source, with nothing added.
"Collagen is the most overlooked supplement in most people's protocols. Everyone focuses on muscle protein — but connective tissue health determines how long you can stay active. I've taken it daily for 15 years."
— Charles Barber

What's inside
One ingredient. Full amino acid profile.
Grass-fed bovine collagen peptides
Hydrolyzed for maximum absorption — broken into dipeptides and tripeptides that pass through the gut wall intact and signal collagen synthesis in the bloodstream. At 6g protein and 24 calories per tablespoon, it adds meaningful protein with a minimal calorie load.
Glycine
The most abundant amino acid in collagen. Primary building block for gut lining, liver detoxification, and new collagen fibre formation.
Hydroxyproline
Unique to collagen. When hydroxyproline-containing peptides appear in circulation, they directly trigger fibroblast collagen production. This is the primary mechanism behind supplementation research.
Proline
Structural amino acid that provides the rigid backbone of collagen fibres. Essential for collagen stability and connective tissue formation.
8 essential + 10 non-essential amino acids
mCollagen delivers a full amino acid profile — including all 8 essential amino acids. At 24 calories and 6g protein per tablespoon, it adds meaningful protein without loading calories.

Supplement facts
What you're getting, in full

HOW TO USE
Easy to incorporate. Impossible to skip.
1
In coffee or tea
Add 1–3 tablespoons to your morning drink. Dissolves fully — no change to taste or texture.
2
Post-workout
Collagen synthesis in joints and tendons peaks within 60 minutes of exercise. Taking collagen in this window, with a source of vitamin C, maximises the benefit.
3
In soups, sauces, or baked goods
Heat-stable and flavour-neutral. Stirs into any warm liquid without clumping or gelling at room temperature.
Suggested daily amount
1 tablespoon (7g) as a daily minimum. 2–3 tablespoons for active recovery or visible skin improvement goals.


What it does
Three things most people notice first
Skin elasticity and firmness
Multiple peer-reviewed studies show hydrolyzed collagen supplementation increases skin elasticity and hydration within 8–12 weeks of consistent daily use. The peptides stimulate fibroblasts — the cells that produce collagen and elastin.
Joint comfort and cartilage integrity
Collagen is the most abundant structural protein in joint cartilage. Regular supplementation supports cartilage structure and reduces post-exercise joint discomfort over time.
Gut lining support
Glycine — the dominant amino acid in collagen — is a primary building block of the intestinal epithelium (gut lining). Consistent collagen intake supports barrier function and reduces permeability.
What sets mCollagen | Grass-Fed Collagen Peptides apart
mCollagen vs. standard collagen supplements
Most collagen products use grain-fed or mixed-source bovine with undisclosed origins. mCollagen is exclusively US grass-fed, pasture-raised — with a higher glycine and proline content that matters for both joint and gut applications.

WHERE MCOLLAGEN COMES FROM
US grass-fed, pasture-raised. No GMO, no glyphosate.
Sourced exclusively from cows raised on pasture in the USA — not imported, not grain-fed. Grass-fed cattle produce collagen with a superior amino acid profile: higher glycine and proline content compared to grain-fed sources. Free from GMOs, glyphosate, added hormones, and antibiotics. Lab tested for purity on every batch.
