PrimaGround’s marine collagen is sourced from wild-caught North Atlantic cod skins — the cleanest, lowest-mercury collagen substrate we’ve tested. Each batch is hydrolyzed into peptides between 2–5 kDa, the molecular weight range with the strongest evidence for gut and dermal bioavailability.
One scoop delivers 11g of pure type I and III collagen alongside 18 amino acids, including the glycine and proline your body uses to rebuild connective tissue, skin matrix, and joint cartilage.
What’s inside
- 11g hydrolyzed marine collagen peptides per scoop
- Type I & III (the types found in skin, tendons, bone matrix)
- Wild-caught Norwegian cod, single-origin, MSC-certified
- Heavy-metal tested below ND limits every batch
How to use
Stir one scoop into coffee, smoothie, or 8oz of water. Tasteless and unscented — it disappears into anything liquid. Most users notice nail and skin changes around week 6; joint feedback typically takes 8–12 weeks of daily use.
What it isn’t
This isn’t bovine, porcine, or chicken collagen. It isn’t bone broth powder. It isn’t blended with flavoring, stevia, or ‘beauty complex’ fillers that obscure the actual dose.
