What makes TruMarine® Collagen the gold standard?

TruMarine® is the only marine collagen of its kind available in North America. Sourced exclusively from wild-caught fish in the deep, clean waters of the South Pacific, not farmed, not from fish skin, and not all marine collagen is sourced this way. Ultra-pure, Premium Select Grade, and clinically proven to deliver 1.5x greater bioavailability than other leading brands, meaning your body absorbs and uses significantly more of what you take.

The result is a clean, highly bioavailable collagen that supports skin health, hair, nails, joints, and bone density over time.

Is TruMarine® Collagen clinically proven?

Yes. TruMarine® Collagen has been studied in controlled, double-blind clinical trials with proven results. Its low molecular weight means your body absorbs it more efficiently, delivering the key amino acids that support your body's natural collagen production.

Clinical research supports its benefits for skin health, bone strength, joint comfort, and more.

Studies:

1. Dietary Collagen Peptides Ameliorate the Mood Status of Fatigue and Vigour

2. Comparison of the quantity and structures of hydroxyproline-containing peptides in human blood after oral ingestion of gelatin hydrolysates from different sources

How does TruMarine Collagen support healthy aging?

Your body's natural collagen production begins to decline in your mid-20s. TruMarine® works by delivering key amino acids that support your body's ability to produce and maintain collagen over time.

Studies show that even 5 grams daily can support visible improvements in skin hydration and elasticity in as little as 4 to 8 weeks, alongside long-term benefits for joint comfort, bone density, and connective tissue strength.

Easy to use

Virtually tasteless, odourless, and dissolves clear. Add it to anything without changing the way it tastes.

Our favourite ways to use it: coffee, tea, smoothies, yogurt, oatmeal, juice, soup, lemon water, baked goods, and protein shakes.

Serving size: 1 scoop or stick pack daily.

Storage: Keep in a cool, dry place. Seal tightly after each use.

Caution: If you are pregnant consult a healthcare practitioner prior to use. Discontinue use if you experience any adverse reactions.
