I take 1500mg per day. One 500mg pill with each meal. I went up to 2000 but it was too high a dosage for me. I don't know if they make them in higher dosage, but I do believe I know why they make you take them this way....

If they have you take them throughout the day, then the medication is always working in your body. It's like someone with Diabetes. Once a day would be too much of a boost and a downer. Too much roller coster effect. Where as this way, it's a little at a time but constant. Your body will work better with the meds this way.

Hope this helps!
