WHEY PROTEIN is a 100% natural protein concentrate of whey and is specially ultrafiltered under low temperature to be low in fat, lactose and carbohydrates. WHEY PROTEIN is a rich source of glutamine-rich biologically active proteins. Fifty-one percent of the proteins found in whey are from BLG (Beta-Lactoglobulin), 20% of whey is alb (Alpha-Lactalbumin), 10% Immunoglobulin, 10% Albumin, and 7% minor fractions (Beta-Microglobulin, lactoferrin, lactoperoxidase, lysozyme, lactolin and relaxin). Albumin is of particular interest to researchers because of its elevated concentrations of glutamylcysteine, a precursor to the antioxidant glutathione.
WHEY PROTEIN supports muscle development because it is the richest natural source of BCAAs (Isoleucine, Leucine and Valine), important fuel components of muscle tissue. BCAAs are depleted from muscle tissue following strenuous exercise, which can cause catabolic loss of protein. BCAAs suppress proteolysis which is the breakdown of muscle tissue. BCAAs are important as a metabolic fuel for muscle and other tissues by their involvement in the alanine cycle (a process of energy production from BCAAs). BCAAs have been known to enhance performance in moderate as well as intense exercise by improving endurance. Each scoop (23 grams) of WHEY PROTEIN provides a total of 4. 6 grams of BCAAs. No other source of protein provides as much BCAAs as whey.
Jarrow FORMULAS® 100% all natural WHEY PROTEIN is rich in glycomacropeptides, which are biologically active proteins that improve the digestion and absorption of nutrients and growth of bifidobacteria.
WHEY PROTEIN is manufactured using a vegetarian rennet enzyme and is specially processed to concentrate and preserve glutamine. Predigested whey, such as that found in peptides and hydrolyzed whey products, resultsin a loss of glutamine. Therefore, Jarrow FORMULAS® whey is not hydrolyzed. Also, WHEY PROTEIN is extremely rich in essential amino acids that raise the biological efficiency of the protein.
Jarrow FORMULAS® WHEY PROTEIN is certified to be Grade a quality and does not contain pesticides or herbicides and is negative for antibiotics (each batch is tested for antibiotics).
