The Biological Value (BV) is a measurement of how much nitrogen is absorbed by the body. Whey protein has the BV of 100. That means your body absorbs all of the nitrogen. Nitrogen is essential for the production of protein in your body. Whey Good protein is a blend of instantized and micro-filtered Whey Protein concentrate, Whey Protein isolate and hydrolyzed whey protein concentrate. Your body can only absorb a certain amount of nitrogen at once. By blending different proteins with different profiles your body is being fed an optimized physiological function of protein. Enhanced Support Arabinogalactin (AG) is a soluble fiber derived from the Western Larch trees, which has been studied for its ability to support digestion and immune support. AG also functions as an aid to friendly pro-biotic bacteria growth, through its effect on pH in the colon. The addition of these soluble fibers to Whey Good protein make this a reat product for a healthy lifestyle. Fructooligosaccharides (FOS) How can FOS increase the absorption of nutrients? FOS acts as a pre-biotic nutrient to bifidobacteria and lactobacillus, located in the large intestine. The good bacteria help maintain and stabilize intestinal flora. Studies indicate that FOS supports digestive enzymes in the digestive tract, potentially leading to better absorption of nutrients. Whey the difference.
