You probably need magnesium. Read this to find out which kind you should use.


By Theron Hutton MD


Magnesium is a vital mineral that plays a role in numerous bodily functions, including the regulation of muscle and nerve function, heart rhythm, and bone health. It is also involved in energy metabolism and protein synthesis. As such, magnesium supplements are often used to treat or prevent magnesium deficiency, which can lead to a range of symptoms including muscle weakness, fatigue, and irritability.

There are several different types of magnesium supplements available on the market, each with its own unique set of properties and potential applications. These include:

  1. Magnesium oxide: This is the most common form of magnesium supplement, and is often used to treat constipation due to its high fiber content. It is also sometimes used as a dietary supplement to boost magnesium intake.

  2. Magnesium citrate: This form of magnesium is highly bioavailable, meaning it is easily absorbed by the body. It is often used as a treatment for constipation due to its laxative effects.

  3. Magnesium glycinate: This form of magnesium is bound to the amino acid glycine, which may make it easier for the body to absorb. It is often used to treat muscle cramps and spasms, as well as anxiety and insomnia.

  4. Magnesium threonate: This form of magnesium is thought to be able to cross the blood-brain barrier more easily than other forms, making it a popular choice for those seeking to improve brain function. It is also sometimes used to treat anxiety and depression.

  5. Magnesium chloride: This form of magnesium is often used topically, as it can be easily absorbed through the skin. It is often used in the form of transdermal patches or creams to treat muscle pain and cramps.

In general, it is important to consult with a healthcare provider before taking any dietary supplement, including magnesium. This is especially true for those with kidney disease or other medical conditions, as well as for pregnant or nursing women. It is also important to follow dosage instructions and not exceed the recommended daily intake of magnesium, as excessive intake can lead to diarrhea, nausea, and other side effects.
