Magnesium is the fourth most abundant mineral in the human body. It is involved in more than 300 enzymatic reactions, including those that convert food into energy and those that regulate the nervous system. And it has a specific problem: sustained stress depletes it at a rate that diet alone cannot always replenish.
What magnesium does in the body
Magnesium has several roles recognized by EFSA with official claims:
- Contributes to normal energy metabolism: it helps convert what you eat into usable energy for the body.
- Helps reduce tiredness and fatigue: when levels drop, that feeling of always running on half-empty appears.
- Contributes to the normal functioning of the nervous system: it regulates the transmission of signals between neurons.
- Contributes to normal psychological function: its deficiency is associated with increased irritability and difficulty managing stress.
Why stress depletes magnesium
When the body activates the stress response, it releases cortisol and adrenaline. These hormones increase urinary excretion of magnesium — meaning the body eliminates it faster. At the same time, chronic stress raises the body's need for magnesium to keep the nervous system in balance. The result is a cycle: more stress, less magnesium; less magnesium, harder to manage stress.
Magnesium and B vitamins: why they go together
Vitamins B3, B5, and B6 share with magnesium the role of supporting energy metabolism and the nervous system. B6 in particular contributes to normal psychological function — something key on the most demanding days. That's why in divain ZEN ADAPT they come together: they complement rather than overlap.
Magnesium forms and bioavailability
Not all magnesium supplements are absorbed equally. Magnesium oxide, the cheapest form, has very low bioavailability. Forms like citrate, bisglycinate, or malate are better absorbed and cause fewer digestive issues. If you're choosing a supplement, the type of magnesium matters as much as the dose.
How much magnesium you need
The reference intake in the EU is 375 mg per day for adults. ADAPT provides between 19% and 38% of the daily reference value, as a complement to what you already get from your diet — not as a substitute.
Who it's for and who it's not for
It is suitable for adults with sustained stress, chronic tiredness, or a diet low in leafy green vegetables, nuts, and legumes. At high doses it may have a laxative effect. It is not recommended for people with kidney failure without first consulting a healthcare professional.
