I am currently taking 2-3 60mg capsules of soy isoflavones, spread out through the day. This keeps the tinnitus somewhat quite. Higher doses of the soy isoflavones keeps it completely quite for a few hours every day and the tinnitus at a low sound level the rest of the day. But, I had ER positive breast cancer and was told not to take soy products. Since the tinnitus gets really bad at times and I can not concentrate, when not taking the soy, I have chosen to take the least amount of soy I can and hope that the taurine capsules that I am taking will kick in, in about 3 weeks. This will allow me to get off the soy products.
