Magnesium deficiency causes an unhealthy balance of phosphorus and calcium in saliva, which damages teeth. High-dose calcium with or without vitamin D without a balancing amount of magnesium triggers a cascade of events leading to bone loss. Magnesium blocks the neuroinflammation caused by calcium deposits in the brain.
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.
