Magnesium comes in different forms and each plays a different role in your body, from mood to metabolism. In fact, magnesium is a hugely important mineral, playing a role in over 300 enzyme reactions in the human body, supporting muscle and nerve function, energy production and optimal brain function.

The NHS advises adults should aim for 300mg of magnesium a day to maintain optimal levels. Magnesium can be found in wholemeal bread, nuts, spinach and other dark green leafy vegetables.

Make sure you choose the right form if you are looking to magnesium for its relaxation benefits. Magnesium glycinate is one of the most common magnesium supplements used for achieving better sleep due to its combination with glycine, a sleep-inducing amino acid.
