A lack of magnesium in the diet can cause or exacerbate common conditions such as migraines, attention deficit disorder (ADD), PMS, depression, asthma, fibromyalgia, tremors and allergies. It may explain why many people suffer from more than one of the above problems, which have all been linked to magnesium deficiency.
Magnesium deficiency symptoms may include overactivity of nerve and muscle impulses leading to tremors or nervous system irritability. Cramps may also be a sign of a lack of magnesium along with muscle spasms or weakness. A lack of magnesium can affect calcium metabolism leading to serious problems for those prone to osteoporosis or soft, weak bones. Magnesium deficiency is also a cause of elevated blood pressure which can lead to an increased risk of strokes. Disturbed sleep patterns and poor memory are other known symptoms.
