Why are you cutting the pill with Magnesium Oxide?
This got a good rating on [...], but it contains Magnesium Oxide, which is junk. Basically a placebo, with 4% bioavailablity. I would not buy this again - it's just a way to cut the pill's cost - the Oxide form of Magnesium is also of course the cheapest. Go with Doctor's Best, instead. Much better form - The Chelate is the way to go with pill-based Magnesium. Only Epsom Salt baths (Magnesium Chloride) exceeds it in bioavailability (and even that is still only at 50%.
