Bay,
This is from the Power Surge treatments and recommendations article.
http://www.power-surge.com/recommend.htmMagnesium (500 mg - 1,000 mg. per day): Recommended: 500 mg. of magnesium daily as needed for palpitations or migraines (500 mg. at a pop), even for anxiety and depression. Magnesium, a much under-rated mineral, has finally come into its own as one of the most beneficial minerals you can add to your diet. I once heard a nutritionist say, "If it spasms, give it magnesium," which is why magesium is excellent for palpitations and migraines and could be helpful to those who experience internal shaking. Magnesium is also known as the "anti-stress mineral" and has been known to help improve depression, promote cardiovascular health and keep teeth whiter. Magnesium may be helpful with menopause, mood swings and PMS symptoms. A study performed involving 32 women found that magnesium taken from day 15 of the menstrual cycle to the onset of menstrual flow could significantly improve premenstrual changes in mood. Studies of large populations have shown that the more magnesium people take in, the lower their blood pressures. This is partially due to magnesium. I recommend magnesium on Power Surge for things like migraines and palpitations. It's a very underrated mineral. Magnesium is extremely effective in lowering the blood pressure. It may reduce palpitations, strokes and heart attacks. It can decrease migraine headaches and increase the effects of a low sodium diet. The amount would be about 800 mg a day and you can obtain it in fresh fruits and vegetables. You will find 400 mg. daily in the recommended dose of Power Surge's Active Women's Multi
