Bioavailability is the proportion of a drug or other substance which enters the circulation when introduced into the body and is able to have an active effect. Clean Lean Protein has high bioavailability.
Older studies have shown an absorption rate of around 89% of the protein. That compares well with any other protein. It also has a PDCAA (protein digestibility corrected amino acid score) of 1.0 which is the same as the gold standard proteins of egg and whey.
