Purely Potent Our Original formula is made with natural marine collagen. Nothing else. Activated Collagen Our marine collagen is activated through a natural hydrolysation process. So our peptides are small in weight – and high in impact. Enzymes break raw collagen down into a low-weight peptide powder (from 300,000 Daltons to as low as 2,000). It’s bioavailable with an absorption rate over 90% and highly effective. Heat Stable Natural Marine Collagen is heat stable. Whether you stir into cool water or your morning coffee, it’s just as effective. Sustainably Sourced Natural Marine Collagen is made from sustainably sourced fish skin. More specifically, our collagen is made using the discarded skin of both wild and responsibly farmed fish (to avoid placing too much demand on one species). Tried and Tested Every batch of marine collagen is tested for heavy metals, mercury and other contaminants. So it’s not just effective, but safe.
