First, take magnesium MALATE CAPSULES, not the TABLETS, with lemon juice first thing in the morning and last at night. This will greatly increase magnesium absorption, lemon juice, taken with all supplements.
Then make your own magnesium oil, just add epson salts or magnesium chloride to the oil. Let it sit all day, then start using it.....
It is cheaper to make than to buy, especially if using epson salts!
