Magnesium Glycinate: Frequently asked questions

What types of Magnesium Glycinate are there and what determines a good product?

There are a few different types of Magnesium Glycinate, but the most common ones you’ll see on store shelves are magnesium glycinate chelate and magnesium glycinate malate. Both have been shown to be effective for reducing stress levels in research studies. The difference between them is that one has an extra amino acid attached (malic acid) which may help with absorption and bioavailability. However, there isn’t much evidence showing this makes any real-world differences so it doesn’t really matter too much which type you choose as long as they both contain at least 50% elemental Mg by weight (which means if your supplement says 100 mg per serving then it should actually contain at least 200 mg of actual Mg).

The quality of a magnesium glycinate supplement is determined by the purity, bioavailability and price. A good Magnesium Glycinate should be pure with no fillers or additives. It must also have high bio-availability to ensure that your body can absorb it easily without any side effects such as stomach upset or diarrhea. Lastly, you want to get the best value for money so look out for deals on Amazon when buying online.

Who should use a Magnesium Glycinate?

Anyone who is looking for a natural way to boost their magnesium levels. This form of Magnesium has been shown in studies to be easier on the digestive system than other forms, making it ideal for those with sensitive stomachs or conditions like IBS and Crohn’s disease. It can also help people get more out of their daily diet by helping them absorb more nutrients from food sources that are rich in magnesium such as nuts, seeds and leafy greens.

Based on what criteria should you buy a Magnesium Glycinate?

Quality products should have the following features: no additives, 100% pure Magnesium Glycinate and manufactured in a GMP certified facility. The product must also be free of artificial colors or flavors. It’s important to check if it is made from organic ingredients as well because non-organic supplements may contain pesticides that can cause side effects such as nausea, vomiting and diarrhea.

When buying Magnesium Glycinate, you should look out for the quality of the materials used. It is important that your chosen product has been manufactured from high-quality ingredients to ensure its effectiveness. Also, pay attention to how long a manufacturer has been in business so as to determine whether it can be trusted or not. There are many companies selling low-grade products these days making false claims about their effectiveness and quality just to get more sales which is why we recommend staying away from them at all costs.

What are the advantages and disadvantages of a Magnesium Glycinate?


Magnesium Glycinate is a highly bioavailable form of magnesium that has been shown to be absorbed better than other forms. It also provides glycine, an amino acid which helps with sleep and relaxation.


The only real disadvantage of a Magnesium Glycinate is that it’s not as readily absorbed by the body. This means you need to take more per day than other forms, but this also makes them less expensive and easier on your stomach.
