I can not say enough good things about magnesium breakthrough. I was highly skeptical about the products ability to actual provide relief from every day stressors as I've tried numerous products over the past 10 years. I followed the loading protocol and by week 2 I started noticing a drastic difference. The best way I can explain is normally I have these long "spikes" surrounding my mental state. These "spikes" get bumped and jostled by every little thing that occurs throughout the day, causing a stress response almost immediately. by week 2 these "spikes" had dulled and by the end of loading program they have all but disappeared. I'm currently on a maintenance dose I'm able to go through my day truly not stressing the small stuff and it is amazing. I still get caught up in it from time to time but hey, that's what mindfulness practice is for. Thanks bioptimezer for developing such an amazing product.

I’ve been trying different probiotics and digestive enzymes since 2005. In 2007 I underwent emergency removal of my gallbladder. I’ve finally found what I’d been looking for with Bioptimizers!! I still must watch what I eat, but I have more options now! If you follow their directions, the products work! I take the P3-om, Masszymes and HCL.
