Fortagen provides the optimum amino acid pattern. This powerful vegan protein formula has a net amino acid utilization of nearly 100%. In other words, nearly all of amino acids are used for synthesizing and supplying the body with protein.

Each serving is 10g of active ingredients, which research suggests is equivalent to over 50g of protein from an ordinary whey supplement, or over 70g of protein from plant-based vegan protein powders.
