Life Extension's Ultra Soy Extract lists exceptionally high quantities of Daidzein, Genistein, and general Isoflavones, each at 3125mg, plus 250mg of Soynatto Fermented Soyfood. While soy isoflavones are compounds derived from soybeans that may contribute to well-being, particularly for those interested in phytoestrogen support, the stated dosage for individual isoflavones is very unusual and potentially misleading for typical intake levels.
The product's focus seems to be on delivering a potent soy-derived complex, including fermented soy, which may enhance bioavailability. However, without further clarification on the actual active component yield from the 'soybean extract' and the specific forms of the 3125mg components, it can be difficult for a user to understand the true functional dose. This ambiguity is a consideration for consumers seeking precise supplementation.
