WHAT IS COLLAGEN?

Collagen is the most abundant protein in your body.

It’s the scaffolding that keeps skin smooth, joints flexible, and hair and nails strong.

From your mid-20s, your natural collagen production begins to decline — about 1% less each year. Over time, this leads to visible changes:

Fine lines and wrinkles
Loss of skin firmness
Brittle nails and thinning hair
Stiffer joints

The slowdown is natural, but you can support your collagen levels — if you choose the right type of supplement

TYPES OF COLLAGEN

Walk into a store or scroll online and you’ll see countless options.

But here’s what most don’t explain:

Collagen type matters

Type I: Makes up ~90% of your skin, bones, and tendons.

Type II: Found mainly in cartilage.

Type III: Supports skin, blood vessels, and organs.

Collagen form matters

Collagen in its natural state is too large for your body to absorb.

That’s why the most effective supplements use hydrolyzed collagen peptides — collagen broken down into tiny chains your body can easily use.

Collagen source matters

Marine collagen from fish skin or scales is primarily Type I, with a smaller molecular size than bovine collagen, making it more bioavailable.

Bovine collagen (cow) typically contains Type I and III.

Chicken collagen is mostly Type II, used for joint health.

THE SCIENCE OF

EFFECTIVE COLLAGEN

Research shows that daily intake of 2.5 g or more of high-quality hydrolyzed marine collagen peptides can:

Increase skin hydration
Improve firmness and elasticity
Reduce the appearance of wrinkles
Support strong nails and healthy hair

Marine collagen — especially from fish skin or scales — has a smaller molecular size than bovine collagen, which makes it easier for the body to absorb.
