Clean Lean Protein does not contain detectable quantities of phytoestrogens. Phytoestrogens are estrogens that occur in some plants. Foods containing phytoestrogens include beans, soy products, peas, lentils, some whole grains and seeds like flaxseed, rye, and millet. While there are very low levels in some legumes, the isolation process we use in our protein removes any significant amounts from the sustainable grown European golden peas leaving highly purified naturally derived amino acids.
