Guys, I would be careful with magnesium. From personal experience, I took magnesium citrate (normal dosage) for a month. I will admit, like Bryan said, its probably great for general health. It greatly reduced my PVCs and stomach upset. It also I think lowered my anxiety. But there was a great price to pay. I believe this supplement set me far back in terms of hair and scalp health. Within one month, my hair thinned out considerably and my scalp felt like it was on fire. Terrible itch.
I did a search online, and this may be the reason:
"Studies have shown that supplementing with 30mg of Zinc and 450mg of Magnesium per day can elevate testosterone levels up to 30%!"

Its very strange, I stand behind magnesium completely for heart and stomach upset. But I think it hurts hair badly. Just my experience, I could be totally wrong, but it seemed like more than coincidence as soon as I got off, my scalp returned to normal.
Of course, at the same time, I was taking another new supplement called Lyco-Mato, however I can't see how this would hurt hair since it lowers DHT and has been proven in Harvard studies to help with Prostate cancer. But I got off it at the exact same time I got off magnesium
I actually bought magnesium and lycopene together at the store. Took the recommended dosage for a month. Body felt better but, scalp and hair went to hell. Got off both at same exact time, and things returned to normal.
I should mention that during that time I was on a high glycemic diet (lots of white rice, rice spagetti, basically any rice product) so maybe that was the true culprit all along. Who knows.
