Key Benefits

  • Type I collagen from wild-caught cod for everyday support.

  • Sustainably sourced from pristine North Atlantic waters.

  • With guar gum, which contributes to the maintenance of normal blood cholesterol levels.

Nourish your daily routine with Dr. Mercola’s Wild Caught Marine Collagen. As we age, our natural collagen levels decline—this supplement offers a simple way to top up with Type I collagen, the most abundant form found in skin, bones, and connective tissue. Each serving delivers 1.5 grams of marine collagen in a convenient tablet, making it easy to fit into your day.

Sourced from wild-caught cod, this formula is a sustainable alternative to mammal-derived collagen. It also features guar gum, which contributes to the maintenance of normal blood cholesterol levels when consumed in sufficient amounts. Choose a pure, responsibly sourced collagen to help you feel your best, every day.
