Magnesium is involved in over 300 enzymatic reactions in the body, supporting muscle function, nervous system health, energy production and sleep. Despite its importance, most people in the UK do not get enough magnesium from their diet alone.

This supplement uses a blend of magnesium bisglycinate and magnesium oxide. The bisglycinate form is magnesium chelated to the amino acid glycine, which improves absorption and has a calming effect on the brain. Glycine itself supports sleep quality and relaxation. The oxide component increases the total elemental magnesium per capsule, giving you 133mg of magnesium in each one.

Bisglycinate is one of the best tolerated forms of magnesium. Unlike magnesium citrate, which can loosen the bowels at higher doses, bisglycinate is gentle on the stomach and suitable for long term daily use.

This form is particularly well suited for anyone experiencing stress, poor sleep, muscle tension or cramps. It pairs well with vitamin B6 and vitamin D, both of which support magnesium absorption and utilisation. Most people notice improvements in sleep quality and muscle tension within 1 to 2 weeks, with broader benefits for mood and stress resilience developing over 4 to 8 weeks.

Take 1 capsule with breakfast and 2 capsules with dinner.

This provides 399mg of elemental magnesium daily, which is within the therapeutic range recommended by nutritional therapists for stress, sleep and muscle support.

Splitting the dose across two meals improves absorption and reduces the chance of any digestive sensitivity. The larger evening dose supports the calming and sleep promoting effects of the glycinate form.

If sleep is a particular concern, an additional 2 capsules can be taken 30 minutes before bed. This increases the total daily magnesium to 665mg, which is appropriate for short term use when sleep quality needs additional support.

Magnesium levels build gradually in the body. For best results, maintain consistent daily use over at least 4 to 8 weeks.

Magnesium: glycinate vs citrate vs malate vs threonate?

Magnesium comes in several different chemical forms when sold as a supplement, and they are not interchangeable. They absorb at different rates and have different evidence bases for specific uses. Glycinate is well tolerated and absorbed via a different gut pathway than oxide, making it the typical default for general supplementation, sleep, and anxiety. Citrate is well absorbed but has a more pronounced laxative effect at higher doses. Malate fits energy metabolism contexts. L threonate is brain penetrant for cognitive applications. A 2022 systematic review in the journal Nutrition confirms that direct head to head trials comparing forms for specific clinical outcomes remain limited.
