Experts in Collagen products with a holistic, inside-out approach to beauty & wellness.
Founded in 2003 by elite athlete James Greenwell the Proto-col range was born out of personal experience. Competing in international modern pentathlon, James tore an Achilles tendon late in his career. Collagen was instrumental to his recovery. After retiring from elite sport, he launched the Proto-col brand with a collagen supplement and a wealth of ideas.
With over 17 years of research and expertise in collagen supplementation, Protocol designed their skin & body supplements with specific Bioactive Collagen Peptides®, each with a unique molecular size to target specific areas in the body: Collagen Beauty Supplements to improve skin, hair, nails & cellulite. Collagen Supplements for Joints - targeting cartilage tissue, and their latest innovation Complete Collagen offers twice the science to benefit both skin & connective tissues, which keep your body flexible and mobile.
The true digestibility of the Bioactive Collagen Peptides® is 98.4%. Their unique single helix structure (a narrower shape than other collagen peptides) is absorbed almost intact by the gut cells. Their strong peptide bond is resistant to digestive enzymes that break down weaker peptide bonds. As a result, you consume more collagen and trigger your body to produce its own collagen. The delivery format does not impact the bioavailability of their collagen supplements. Whether you prefer their collagen capsules, collagen tablets, or liquid collagen, they will all work the same way.
