Magnesium supplements

Magnesium supplements are used to treat deficiencies of this vital nutrient as well as to boost the functioning of nerves, muscles, and bones. This nutrient can also be part of dietary supplements designed to improve bone strength or immunity.

Choosing vitamin supplements

Many people who use magnesium supplements also use other vitamins supplements as well. The specific nutrients you choose depends on your specific health condition and general state of health. Common supplements that are used in conjunction with magnesium include calcium supplements, omega-3 fatty acids, and zinc supplements. In some cases, magnesium is combined with other nutrients in a single supplement. Calcium-magnesium supplements are a common combination because both of these nutrients work together to build strong bones. In some cases, vitamin D is also included in the same supplement. Other dietary supplements contain magnesium in combination with chelating agents that help improve absorption.

Using magnesium supplements

Magnesium supplements are available in tablet, capsule, and softgel form. These are typically taken up to three times a day during meals to help make it easier to digest the supplement. People with gastrointestinal disorders may need to take a specific dose of magnesium every day. Magnesium also boosts the uptake of potassium and calcium supplements, so people taking these may also need magnesium supplements. This nutrient may also help lower blood pressure, so magnesium supplements may be used for this purpose as well. Your doctor can help you decide whether and when to take magnesium supplements.
