Femarelle is a dietary supplement that is a mixture of DT56a (a tofu extract) and flaxseed powder, that may act as a selective estrogen receptor modulator (SERM). In 2008 an application was submitted to the European Food Safety Authority to market Femarelle with a health claim, namely that it can reduce the risk for osteoporosis and other bone disorders; the EFSA found that "the food/constituent for which the claim is made, i.e. Femarelle®, has not been sufficiently characterised" and that " a cause and effect relationship has not been established between the consumption of Femarelle® and increased BMD, increased bone formation, or decreased risk of osteoporosis or other bone disorders in post-menopausal women."
