If you’ve resolved yourself to the fact that magnesium is missing in our food and you are ready to buy a dietary supplement, here are 4 qualities you should look for in a magnesium formula.
- Read the label
Many magnesium products contain compounds that are not easily absorbed – or only provide a small increment of elemental magnesium. The 3 most popular magnesium formulations are magnesium citrate, magnesium oxide, and magnesium glycinate. In one clinical study, amino acid chelates like magnesium glycinate demonstrate somewhat higher bioavailability than inorganic compounds like magnesium oxide which is only absorbed by 4%. The bioavailabilities of magnesium aspartate, magnesium citrate, magnesium lactate, and magnesium malate fall somewhere in between. In a clinical trial of 16 subjects, magnesium chloride absorption was found to be the highest of all magnesium forms.
- Look for purity
The manufacturer’s certificate of authenticity guarantees purity from chemical toxins and heavy metals. Some magnesium tablets contain titanium dioxide, an insoluble whitening agent. Although “Generally Recognized as Safe” by the US Food and Drug Administration, titanium dioxide has been linked in research to cancer and neurological damage.
- Ingredient safety
Be aware of magnesium brands that offer elemental magnesium levels that in one serving exceed magnesium’s established upper limit of 350 mg per day. This is a red flag for consumers indicating that the formulas have not been developed by a doctor or by properly following FDA guidelines.
- Calculate the value
Consider magnesium citrate or magnesium glycinate. Often these tablets or capsules will come in 400 mg servings. But, these are just magnesium compounds wherein the ions of each element constantly ionize apart and then bind together. When they are bound together they are can’t be absorbed into the cells. With this type of product, the highest cellular absorption is probably about 20%. So, you think you’re getting 400 mg when you’re really only getting 80 mg! The rest goes down the toilet! And of that 80mg, only a fraction gets into the cells because it’s not a stabilized ion of magnesium.
ReMag checks positive on in all these categories. Plus, its proprietary pico-ionic structure of stabilized magnesium ions means it is absorbed 100% at the cellular level. That may sound like scientific jargon, but what it translates to is “magnesium without the laxative effect.”
