WHERE DOES NATURE MERGE WILD-CAUGHT COLLAGEN COME FROM?

We source our collagen exclusively from wild-caught, deep-sea white fish from the cold waters of the North Atlantic. Unlike farm-raised fish or bovine sources, our collagen is free from antibiotics, growth hormones, and land-based contaminants.

WHAT ARE THE MAIN BENEFITS OF MARINE COLLAGEN PEPTIDES?

Marine collagen is primarily prized for its superior bioavailability; because it has smaller particles (peptides), it is absorbed up to 1.5 times faster than bovine alternatives. Regular intake is scientifically linked to improved skin elasticity, significant reduction in fine lines, and increased dermal hydration within 4 to 8 weeks.

IS YOUR COLLAGEN TESTED FOR HEAVY METALS LIKE MERCURY?

Yes. A major pain point with marine supplements is the risk of toxins found in low-quality environments. Nature Merge is sourced from wild-caught North Atlantic fish, which are naturally lower in contaminants than farm-raised fish. We provide a public Certificate of Analysis (COA) for every batch to guarantee our product is third-party lab-tested for heavy metals and purity.

WHAT IS THE DIFFERENCE BETWEEN TYPE I, II, III, AND IV COLLAGEN?

While 90% of the body’s collagen is Type I (skin, bones, hair), a "Full-Spectrum" approach is essential for total health:

Type I & III: Work together to support skin firmness, muscle repair, and gut health.

Type II: Essential for joint support, making up the cartilage that cushions your knees and elbows.

Type IV: A rare but critical component for the basement membranes in your skin layers.

HOW MUCH COLLAGEN SHOULD I TAKE DAILY FOR RESULTS?

Clinical studies suggest that a daily dose between 5g and 10g is optimal for noticeable changes. While some effects on skin hydration can be seen in as little as 4 weeks, joint and bone health benefits typically require 3 to 5 months of consistent daily use.

The Nature Merge Difference

Sourcing Without Compromise

We source exclusively from wild-caught, cold-water white fish from the pristine North Atlantic waters of Nova Scotia, Canada.

The Full-Spectrum Advantage

(Types I, II, III, & IV)

While competitors stop at Type I and III, our formula provides comprehensive support for skin elasticity (Type I), joint cushioning (Type II), vascular health (Type III), and cellular basement membranes (Type IV).

Superior Bioavailability(<3 kDa)

Our collagen is enzymatically hydrolyzed into tiny peptides with a molecular weight under 3 kDa.

Does it have a fishy taste?

No. Through advanced processing, we have neutralized the sensory profile of the fish. The result is a completely unflavored, neutral-tasting powder that dissolves instantly into coffee or smoothies without clumping or aftertaste.

My skin has changed so much already

My skin has changed so much already. I suffered from dry skin as well as dry eyes. This collagen has helped to soothe both problems. It mixes easy, and has no taste.

Best on the market!

I have been using this for 2 months with great success so far! Great taste and I appreciate the testing for heavy metals. I can enjoy this collagen with confidence.

shake addition

A high quality addition to an existing shake. It blends seamlessly, without detection of change in taste or consistency.

Love it!

I absolutely love this collagen- I put it in hot coffee and hot teas. It is odorless and tasteless and has the texture of powdered sugar which is different than any other collagen I’ve tried. My hair and skin are glowing and I think I can thank the collagen for that in part! Thanks for making a great product, I’m a big fan!

Love that is has no flavor!
