I'm pretty sure that what they say is in this is actually in it, with one possible exception: I'm wondering if they used racemic equol instead of pure S-equol as was in Brotzu's original formula. The problem with this would be that the R- and S- forms have different mechanisms of activity from what folks here have said, and the R- form specifically is the one that might give anti-androgen type side effects. I also think the S- form is more efficacious for what it's actually purporting to do.
One thing that speaks against the idea that they used racemic is the price of Trinov, which is high. Some/most of this can be due to the liposomal delivery mechanism (liposomes are expensive to create iirc), but I believe some of it also is due to having to produce pure S-equol, which is also more costly to produce than R-equol or a racemic mixture. It would really be ashame though if this product's possible efficacy as seem in Brotzu's original formulation was in any way lessened by some sort of cost-saving measure on the part of Fidia.
