I take 500mg of Taurine every Mon/Wed/Fri. I started at daily but seemed to become ineffective. I stopped for a few days then took it again and it worked again so, now it's basically every other day. I also take L-Carnatine 500mg Tue and Fri, Zinc and Magnesium on Monday, and CoQ10 100mg twice daily. Of course every person is different so you need to experiment. The most important thing, monitor yourself, there are those heart rate/O2 monitors and wrist-cuff blood pressure monitors available for about $15 each on that big online reseller named after that river in S. America. I have tried Hawthorne Berries but didn't help me, Saw Palmetto which helps for those special intimate times if your a guy. I gave up on Coreg, just gave me the shoots and chronic cough. Lasix also just makes me stupid/confused but I don't have a water retention problem anyway so that one was pointless. Just on Enalapril and Metoprolol extended release. Keeping my pressure in the 120-140 over 58-72 range with a HR in the 68-85 range. I have CHF with EF 10-15%, member since 1997 :) along with COPD down to 25% lung function. Good luck to you!
