While oxalates are rich in plant foods, the peas used in Clean Lean protein (Pisum sativum) have a reportedly low level of oxalates present. The pisane used is the protein fraction isolated from the rest of the pea, so there should be very small or no detectable levels remaining. If you are sensitive to oxalates or have a history of kidney stones, please discuss our products with your Healthcare Practioner. We do not test for oxalates in Clean Lean Protein.
Since we do not ferment or break down the bacteria, the pisane should be mainly amino acids, so it is unlikely that many purines exist in Clean Lean Protein.
