If you’ve spent any time on social media recently, you’ve probably found yourself wondering whether you should be taking a magnesium supplement. There’s no shortage of influencers listing all the benefits that different types of magnesium supplements have – from boosting brain function to helping ease anxiety and improving sleep.

Indeed, magnesium is an essential mineral involved in hundreds of processes in the body. It helps muscles and nerves work properly, supports energy production and contributes to the maintenance of strong bones and teeth.

Magnesium is also important for maintaining a healthy heart rhythm, regulating blood pressure and blood sugar levels. Many people don’t get enough from their diet, so supplements can be useful in some situations.

But when you look closely at the research, there’s little evidence to suggest that any one type of magnesium supplement has unique benefits over another.

One of the most talked about types of magnesium is magnesium glycinate, often promoted as the best option for sleep. This form combines magnesium with glycine, an amino acid that may improve sleep on its own.

While some research does show that magnesium may improve sleep, these trials do not show that glycinate is any better than other forms. Glycinate’s main advantage is that it’s gentle on the stomach and well absorbed, which may make it easier for some people to tolerate.
