I heard it wasn't? It's the isoflavones that I am afraid of. Might consider whey protein instead except that it tastes so bad (from what I remember using it a couple decades ago).
Soy supplements can have phytoestrogens (which as you say are the isoflavones) so it wouldnt be the best supplemental protein to use. Have you tried casein? Casein protein is superior to whey and burns much slower. Using whey and casein together is best because you'll burn whey quickly for an energy spike and then the casein kicks in and keeps protein blood level up for much longer than whey alone will. It is usually considered okay to eat soy foods like soy burgers, tofu, edamame etc. in moderation but soy supplements should be avoided until better research comes about. There are other protein sources out there. Protein supplements have come a long way as far as taste as of recent years and since they have gotten popular among the bodybuilding set, they have gotten better tasting. They are likely better than you remember.
