The result is premium-quality lactose-free whey protein that is ready to be utilized for muscle repair and energy. Additionally Nutri-Burn contains plant enzymes that help break down protein molecules into smaller better-absorbed amino acids. Nutri-Burn also contains one gram of prebiotic fiber (scFOS) per serving to help support gut health.Mix 2 rounded scoops of Nutri-Burn powder with 1216 oz. cold water or mix to taste.
