A more recent review of randomized trials found that some studies showed benefit of soy supplements on hot flashes; the therapeutic dosage ranged from mg of isoflavones daily. In October 2017, after review of additional scientific studies since the health claim was authorized, the FDA proposed a rule to revoke the claim because numerous studies presented inconsistent findings on the relationship between soy protein and heart disease.
