Our Story

we were the first and we stayed true

withinUs was the first to bring premium marine collagen to North America. We sourced the very best ingredients because we never believed in doing it any other way.

We knew competition would follow.

That was never going to change who we are.

It still does not.

FAQ

the details matter

Is withinUs® a Canadian Company?

Yes. withinUs® is Canadian-owned and operated, founded in Vancouver, BC by Tami Nasu, a third-generation Japanese Canadian who brought the first Health Canada-licensed premium marine collagen peptide to North America over a decade ago. Independent and women-owned since 2013, with no outside investors.
withinUs® products are regulated by Health Canada and licensed with NPNs.
Thank you for choosing to support a Canadian brand.

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 gging?

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.
