Level-1 is comprised of the Level-1 Matrix which is an ultra bio-available, sustained assimilation protein formula consisting of Cross-Flow Micro-Filtrated Whey Protein Isolate, Low Temperature Micro-Filtrated Whey Protein Concentrate, Low Temperature Processed Milk Protein Concentrate, and Sodium Caseinate. The Level-1 Matrix is specifically formulated to deliver the highest quality, premium proteins in a sustained release which mimics the protein assimilation rates of whole food. Level-1 uses only proteins that have been low-temperature processed to take extra precaution to not denature or damage delicate protein fractions.
