Is it possible that Magnesium supplements can cause insomnia?
I have been taking magnesium citrate (100mg twice a day) at 9 am and 3 pm. After 4 days on it a developed insomnia for about 3 days in a row. I am not sure if it is magnesium, but I have taken on 2 different weeks and it has been the same story. It is supposed that magnesium helps with insomnia, but I am not sure in my case. Any comments?
Magnesium definiciency and overdose symptoms are the same. Try a lesser dose - the RDA is 6mg/kg of body weight. (Ie - if you're 100 lbs which is 45.45 kg, you would need 272 mg.) Remember that you also get Mg from food sources, and the FDA doesn't require Mg to be listed on the list (some good sources are milk, beans, avocados, yogurt, spinach…etc.)
