Since I'm a diabetic, I have to be careful of my feet and legs for neuropathy amongst other things. When I started to get leg cramps, I read online that magnesium malate aided in the relief of muscle cramps. I found this item with good reviews and purchased two bottles on sale and noticed a positive improvement: less frequent muscle cramps. In fact, I haven't had a muscle cramp since I've begun consuming this particular magnesium product. I take two capsules at night two hours before bedtime with water, tea or juice. I'm a happy customer with this product. Thank you BioEmblem for a very good product.
