There are many proteins out there that are much better sources, like Whey Isolate. Soy contains estrogen precursors and isoflavones, which negatively affect people with thyroid conditions.

Plant proteins are incomplete, meaning they lack certian amino acids which are essential for tissue buildup. If you insist on being vegan and cannot get a complete protein, take the soy with an amino acid supplement. Other than that, it's pretty useless.
