Better together
Magnesium enhances the potential of other nutrients, like vitamin D and calcium.

So your body can put that nutritional goodness to the best use.

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.
Like a lot of good things in life, Magnesium⁺ is a long-term commitment rather than a quick fix. But even if you don’t feel the difference immediately, that mineral powerhouse is getting to work behind the scenes.
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.
Make it a daily habit, and Magnesium⁺ will continue to support your overall health. You might even notice the benefits our reviewers describe.
