8 Types of magnesium: Which one is right for you?

Magnesium is crucial in numerous bodily functions, making it an essential mineral for overall health and well-being.

Research indicates that magnesium supplements can significantly boost exercise performance, especially in older adults and individuals with a magnesium deficiency [1].

Additionally, epidemiological studies suggest that diets high in magnesium are linked to reduced rates of various diseases. However, clinical trials on the effectiveness of magnesium supplements for treating specific conditions have yielded mixed results [2], [3].

The discrepancy may be due to the combined benefits of multiple nutrients found in magnesium-rich foods compared to the isolated effects of single-nutrient supplements.

With various forms of magnesium available, it can be challenging to determine which one best suits your needs.

Which type of magnesium is best?

When choosing the best type of magnesium, the answer largely depends on your specific health needs and goals. Each form of magnesium offers unique benefits, making some more suitable for certain conditions than others.

Let’s discuss eight different types of magnesium, highlighting their key benefits and who they might be best suited for. 

1. Magnesium citrate

Magnesium citrate is a popular magnesium supplement known for its high bioavailability, meaning it is easily absorbed by the body. This form is often used to support digestive health, particularly in relieving constipation [4]. 

Additionally, magnesium citrate can aid in muscle relaxation and overall magnesium replenishment.
