Magnesium helps relax the spastic blood vessels that cause pain and numbness of the fingers. Pain, inflammation, muscle spasm, muscle tension, and scarring can all be treated with magnesium. Magnesium reduces lactic acid buildup that can result in post-exercise pain. Serotonin balance is magnesium-dependent. Deficiency of serotonin can result in migraine headaches and depression. Magnesium deficiency contributes to atherosclerotic kidney failure. Magnesium deficiency creates abnormal lipid levels and worsening blood sugar control in kidney transplant patients. It’s important for kidney patients to receive magnesium that is absorbed directly into cells. Magnesium prevents muscle tension that can prevent restful sleep. Also, sleep-regulating melatonin pathway production is disturbed without sufficient magnesium.
