Hormonal alteration is the main problem when it comes to soy-based protein supplements.
While soy is rich in essential amino acids, it is also packed with phytoestrogens (. Phytoestrogens, when ingested, mimic the estrogen hormone and can send the endocrine system on a roller coaster. Not to mention the fact that up to 95% of the soy used to make protein supplements is genetically modified. Genetically modified soy contains a chemical called glyphosate, which is responsible for hormonal imbalance, miscarriage, and even birth defects in newborns. The daidzein and genistein found in soy can cause erectile dysfunction, decreased libido, and breast enlargement in men. Whey protein is known to increase the production of a hormone called IGF-1, or insulin-like growth factor (1).

If the patient agrees to stop taking supplements and hormone studies do not normalize within six to nine months a referral to endocrinology is indicated. When large amounts of protein supplements are consumed for an extended period of time there is a greater risk of developing kidney disorders. Secondary testicular failure (hypogonadotropic hypogonadism) due to the use of sports supplements is an exclusionary diagnosis and referral to an endocrinologist may be necessary. In contrast bodybuilders and athletes lead a very active lifestyle and therefore may need proteins up to 1 to 1.5 g per pound of weight for better muscle growth and recovery. Kidney deterioration kidney stones and kidney failure are the likely side effects of taking excessive amounts of protein supplements.
