Take one dose per day, first thing in the morning on an empty stomach
along with a B6. Try 1500mg and see how you feel. You can take
up to 4000mgs but many find it works best at a more moderate dose. It will give you back your mental and physical energy. Do some aerobic exercise, too. Anything that gets your heart and breathing rate up like fast walking, jogging, bicycling, stairmaster, etc. I'd also suggest taking a mega-mineral supplement with lots of magnesium, zinc and phosphorous.
