Where Your Collagen Comes From. And How It Gets Absorbable.
Collagen is only as good as its source and its processing. Ours starts in a pasture and ends as peptides small enough for your body to actually use.
Grass-Fed Bovine
Sourced from pasture-raised cows. The hides and connective tissue are naturally rich in Type I & III collagen.
Whole Collagen
Raw collagen is a large triple-helix protein. Too big for your gut to absorb efficiently on its own.
Hydrolyzed
Enzymes break the helix into small peptides. This is also why the powder ends up completely flavorless.
Absorbed
Small peptides pass into your bloodstream and deliver the amino acid building blocks where your body needs them.
Why Type I & III. Not Just "Collagen."
Most labels say "collagen" and stop there. We don't. There are 28 known collagen types, but two of them do nearly all the structural work in your body. Those are the two in this tub.
Type I · The Framework
The most abundant collagen in the human body. It forms the structural scaffolding of your skin, bones, tendons, and ligaments.
- Skin elasticity and firmness
- Strong hair and nails
- Tendon and ligament structure
- Bone matrix support
Type III · The Support System
Found alongside Type I in fast-repairing, flexible tissue. It supports the structures that keep you moving and recovering.
- Muscle tissue structure
- Blood vessel walls
- Gut lining integrity
- Recovery-phase tissue repair
Types I and III make up roughly ninety percent of the collagen in your body, and your natural production declines every year starting in your mid-twenties. Hydrolyzation breaks our peptides down small enough for your body to actually absorb and put back to work.
Three Ingredients. Each One Earns Its Spot.
Hydrolyzed Bovine Collagen
Grass-fed, pasture-raised Type I & III peptides broken down into easily absorbable amino acids, including glycine and proline, the building blocks of skin, joint, and connective tissue health. Bonus: it also delivers 10.5g of protein per serving to support your recovery.
Hyaluronic Acid
A compound your body already makes to retain moisture in skin and cushion joints. Paired with collagen and vitamin C, it supports skin hydration and joint lubrication from the inside.
Vitamin C
Your body cannot synthesize collagen without it. Vitamin C acts as an essential cofactor in collagen formation, which is why we built a full daily value into every serving instead of hoping you take it separately.
What Collagen Actually Does For Your Skin.
Your skin's structure and bounce come from a scaffold of collagen fibers in the dermis. That scaffold thins as natural production drops. Here's the difference it makes.
The Science Behind The Scaffold
Everything above traces back to one idea: collagen is the structural protein your body builds connective tissue from. Here is how a hydrolyzed, grass-fed source fits into that natural process.
Broken Down Small
Hydrolyzed collagen is already cleaved into short peptides and free amino acids, mainly glycine, proline, and hydroxyproline. That small size is what lets the body absorb them through the digestive tract and carry them into circulation.
Supplies The Raw Material
Those amino acids are the same building blocks your body draws on for its own collagen-rich tissue: the dermis beneath your skin, along with tendons, ligaments, and cartilage.
Rounded Out By Cofactors
Vitamin C is a cofactor the body uses in forming collagen, and hyaluronic acid is the molecule tissue uses to hold water. That is why both are built into every serving.
Skin gets its firmness, stretch, and moisture-holding capacity from the collagen scaffold in the dermis. The body's natural collagen levels decline gradually with age, which is why many people choose to add a clean, absorbable source to their daily routine.
Your Morning Coffee Just Became Your Recovery Protocol.
Scoop
One scoop delivers the full 10g dose. No measuring, no math, no proprietary blend guesswork.
Stir Into Anything
Dissolves fast and clean in 8 to 16 oz of any liquid. Best in warm or hot drinks: coffee, tea, or blended into a protein shake.
Taste Nothing
No flavor, no odor, no texture change, no color change. If you can taste your collagen, it wasn't hydrolyzed right. Ours disappears.
Zero sugar. Zero sweeteners. Keto and fasting friendly. It adds function to your drink, not calories worth counting.
