Ultrafiltered whey protein concentrate and cross-flow microfiltered whey protein isolate (CFM WPI). It's fortified with the patented protein enzyme matrix Aminogen. Scitec Nutrition uses a superior form of whey protein concentrate that is produced through an advanced proprietary low-temperature ultra filtration process that concentrates native whey proteins. CFM is an advanced process that uses a high-tech ceramic filter to carefully isolate the whey protein from fat, lactose, denatured and damaged whey. By using this process, the purest, most natural, low fat undenatured whey protein is produced. Sci-Pro features a variety of nutritional and functional properties and is the richest source of branch chain amino acids of all the protein types. BCAAs are cannibalized first since they are an important source of energy during exercise and play a crucial role in protein synthesis.
