It is not advisable to abuse this mineral because, in high doses, it is toxic, manifesting itself in the form of mental stupidity, weakness in muscles or problems of breathing.

- Do not take magnesium supplements if you have kidney problems, congestive heart abnormalities or are taking any medications. Its use in combination with certain antibiotics (tetracycline) inhibits their effectiveness.

- Certain components block the absorption of magnesium: Excessive calcium ingestion, oxalates rich foods (spinach, rhubarb, amaranth or wormseed), the alcohol ingestion, foods very rich in fiber, like bran.

- Magnesium, when it is taken in the form of supplements, needs calcium so that both minerals are complemented and work well.
