26 Clinical Trials Prove It: Collagen Really Works for Anti-Aging

The Meta-Analysis That Changed Everything

For years, skeptics questioned whether oral collagen supplements actually work. Can swallowing collagen peptides really improve your skin? Or is it just expensive marketing?

Now we have the answer—and it comes from one of the most comprehensive reviews ever conducted.

What the Research Revealed

In 2023, researchers analyzed 26 randomized controlled trials involving 1,721 patients to settle the question once and for all. Published in the peer-reviewed journal Nutrients, this systematic review and meta-analysis examined the effects of hydrolyzed collagen supplementation on skin health (Chen et al., 2023).

The results were definitive:

Skin Hydration: Significantly improved (Z = 4.94, p < 0.00001)

Skin Elasticity: Significantly improved (Z = 4.49, p < 0.00001)

In scientific terms, a p-value less than 0.00001 means the results are extraordinarily reliable—there's less than a 0.001% chance these improvements happened by coincidence.

What "Significant Improvement" Actually Means

This wasn't about subtle changes that required a magnifying glass to notice. Study participants experienced:

• Measurably increased skin moisture levels

• Improved skin's ability to bounce back (elasticity)

• Visible reduction in the appearance of wrinkles

• Better overall skin texture and appearance

And these weren't short-term studies—many participants saw continued improvements over weeks and months of consistent supplementation.

Marine Collagen Showed Particularly Strong Effects

While the meta-analysis examined various collagen sources, marine collagen demonstrated especially promising results for skin health. This aligns perfectly with what we know about marine collagen's superior bioavailability—when your body absorbs it better, you see better results.

The Nordic Nutrients Promise

Our Pure Marine Collagen delivers the same type of hydrolyzed collagen peptides used in these clinical studies:

✓ Highly bioavailable 3 kDa peptides

✓ 5,000 mg per serving—clinically relevant dosing

✓ Type I collagen—the predominant collagen in human skin

✓ Wild-caught Nordic sources—pure and sustainable

This isn't just another beauty trend. It's science-backed skin care from within.

When 26 clinical trials and 1,721 participants agree—collagen works.
