What to look out for when buying magnesium


4 things to watch out for

There is a staggering amount of different magnesium supplements on the market. If you type “magnesium” in the Health category on Amazon, you will get more than 8,000 results! How to choose the one that will be the safest and most effective from so many? This article will help you in your search.

1) Evaluate the form

Many magnesium products contain magnesium compounds that are not easily absorbed – or provide only a small amount of elemental magnesium. The three most popular magnesium compounds are magnesium citrate, magnesium oxide and magnesium glycinate. A clinical study shows that amino acid chelates such as magnesium glycinate have a higher bioavailability than inorganic compounds such as magnesium oxide, which has an absorption rate of only 4%. The bioavailability of magnesium aspartate, magnesium citrate, magnesium lactate and magnesium malate lies somewhere in between. The clinical study of 16 subjects found that the absorption of magnesium chloride was the highest of all forms of magnesium.

2) Seek purity

Some magnesium tablets contain titanium dioxide, an insoluble bleaching agent. Although it is “generally recognized as safe” by the U.S. Food and Drug Administration, titanium dioxide has been linked to research on cancer and neurological damage.

3) Check the safe dosage

Many brands of supplements contain levels of magnesium that exceed the upper limit of 350 mg of magnesium per day in a single dose. This is a red flag to consumers, indicating that the formulas were not developed by a physician or using FDA guidelines. (Or EMA in Europe).

4) Calculate the magnesium value

Take magnesium citrate or magnesium glycinate. These tablets or capsules are often supplied in 400 mg doses. However, it is only a magnesium compound, with ions of each element constantly ionizing, and then binding together. When bound together, they are not absorbed into the cells. The best cellular absorption rate for this type of product is about 20%. You think you are receiving 400 mg when in fact you are only getting 80 mg!


I hope this list helps you narrow down your search and find the best product. And if you want to make it easy, choose ReMag Magnesium. It meets all four of the above criteria.
