Frequently asked questions

Research shows that magnesium glycinate (what we use in our formula) is the most absorbable magnesium compound—meaning your body can put it to the best use.

It’s particularly effective for supporting sleep, psychological function, muscle health, and nervous system function. It’s also kinder to your digestive system, so you can top up magnesium levels without too many trips to the loo.

Yes—our bodies can’t produce magnesium and lots of adults are deficient.

The European NRV is 375mg. Each Magnesium⁺ capsule contains 150mg of elemental (active) magnesium sourced from magnesium glycinate. So, a single serving (2 capsules) of Magnesium⁺ delivers 300mg of elemental magnesium, providing 80% of your recommended daily intake. Sorted.

Magnesium⁺ supports over 300 of your body’s biochemical functions, keeping your engines running around the clock. So you can take it at any time of of day, with or without food. Since magnesium is known for its relaxing, calming properties, some people prefer to take it before bed.

Playing a key role in over 300 of your body’s biochemical functions, magnesium contributes to your sleep, energy, muscle function and recovery, psychological function, nervous system, bones and teeth, and cell division.

    Amazing results

    I've always had issues with waking up many times in the middle of the night. This on top of heavy workout would cause muscle pain would make it even worse. I've now been using it over a month and I almost never wake up until the morning, no more muscle pains either. My deep and REM sleep went up significantly as well. I wake up refreshed every morning even with less than optimal sleeping time. I wish I knew years ago that magnesium would help me.
