Muscles that stay clenched, tension that never drops, evenings without real recovery — where is your magnesium going?
MAG-COMPLEX by VitalisPro brings four forms of magnesium into a single capsule: bisglycinate, citrate, marine and oxide. Magnesium contributes to normal muscle function, to the normal function of the nervous system and to the reduction of tiredness and fatigue.
- ✓ Contributes to normal muscle function — for the muscle that will not let go after a long day or after training
- ✓ Contributes to the normal function of the nervous system and to normal psychological function
- ✓ Contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism
- ✓ Why all four together? A single form gives you a single advantage. Bisglycinate and citrate for digestive gentleness, marine and oxide for magnesium content — here you get all four in one capsule.

Magnesium, explained plainly
What is MAG-COMPLEX 400 mg by VitalisPro?
MAG-COMPLEX is a food supplement delivering 400 mg of magnesium per capsule, split evenly across four forms: bisglycinate, citrate, marine magnesium and oxide. The shell is a cellulose vegetable capsule, and the box holds 60 capsules for a net weight of 24 g.
Magnesium is one of those minerals the body does not manufacture: the only source is food. Between refined products, coffee, long stretches under pressure, hard training, and the heat and sweating of a Moroccan summer, securing that intake day after day becomes a genuine issue.
The difference lies in the formula itself. Most supplements rely on a single form of magnesium, yet each one behaves in its own way: bisglycinate is chelated to glycine and known for its digestive gentleness, citrate is an organic salt whose absorption has been studied, marine magnesium arrives with a natural mineral entourage, oxide is a concentrated mineral form. VitalisPro chose to bring all four together in one capsule rather than favour a single one.
Magnesium contributes to normal muscle function, to the normal function of the nervous system, to normal psychological function, to normal energy-yielding metabolism, to the reduction of tiredness and fatigue, to electrolyte balance and to the maintenance of normal bones. The product is ONSSA authorised under approval CAPV.2.299.23, and reaches you with cash on delivery anywhere in Morocco.
The actives and their role
| Component | Per capsule | Role |
|---|---|---|
| Magnesium bisglycinate | 100 mg | A form chelated to glycine, known for its digestive gentleness. Magnesium contributes to the normal function of the nervous system. |
| Magnesium citrate | 100 mg | An organic salt whose absorption has been the subject of comparative studies. Magnesium contributes to normal muscle function. |
| Marine magnesium | 100 mg | Drawn from sea water, this magnesium arrives with the mineral entourage of its origin. Magnesium contributes to electrolyte balance. |
| Magnesium oxide | 100 mg | The densest of the four in elemental magnesium, for intake measured by weight. Magnesium contributes to the reduction of tiredness and fatigue. |
| Total magnesium | 400 mg | Four forms in a single capsule, for gradual intake and better digestive tolerance. |
| Vegetable capsule (cellulose) | — | A fully plant-based shell, with no animal gelatine. |
| Magnesium stearate (plant origin) | — | A plant-derived processing aid that keeps the dose consistent from one capsule to the next. |
1 to 2 capsules a day with a large glass of water, without exceeding the recommended dose. With minerals, what counts is consistency rather than the first few days: plan a two to three month routine. At one capsule a day, a box of 60 covers two months; at two capsules, one month. Every component is declared exactly as it appears on the box.
Why does magnesium concern your muscles and your nerves?
Magnesium acts as a cofactor in several hundred enzymatic reactions: energy production inside the cell, protein synthesis, nerve signal transmission, and the contraction-and-release cycle of muscle. A reference review published in Scientifica details that cross-cutting role (Schwalfenberg & Genuis, 2017).
On the nervous side, a systematic review in Nutrients revisited the work on magnesium, subjective anxiety and stress; it notes encouraging signals while underlining the need for better-controlled trials (Boyle et al., 2017). A controlled trial was also run in older adults reporting difficulty falling asleep (Abbasi et al., 2012): we cite it as a research reference, not as a promise of results.
That leaves the practical question: why four forms? Because magnesium salts do not behave alike. A randomised, double-blind study compared the bioavailability of magnesium citrate with other preparations (Walker et al., 2003), and marine magnesium sources have been assessed for bioaccessibility and digestive tolerability (Dowley et al., 2024, Methods). Combining all four is a bet on complementarity rather than on picking a winner.
What the European framework for nutrition claims recognises is clear: magnesium contributes to normal muscle function, to the normal function of the nervous system, to normal psychological function, to normal energy-yielding metabolism, to the reduction of tiredness and fatigue, to electrolyte balance, to normal protein synthesis and to the maintenance of normal bones. A food supplement accompanies a varied diet and a balanced lifestyle, it does not replace them. To discover the rest of the range, browse the Sleep and Stress & Anxiety Management sections.
What you are looking for, and what supports it
| This is you if… | What magnesium contributes to |
|---|---|
| Your muscles stay clenched after training or after a long working day | Contributes to normal muscle function and to electrolyte balance |

| You start the day tired despite the hours you slept | Contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism |
| You train regularly and lose a lot through sweating in the heat | Contributes to electrolyte balance and to normal protein synthesis |
| You once tried a magnesium that sat heavily on your stomach | Four forms spread out, including bisglycinate known for its gentleness, instead of a single heavily dosed form |
| You want a formula declared with no grey areas | 400 mg per capsule, four forms with their dosage, a vegetable capsule, and an ONSSA authorised product |
How to use it
1 to 2 capsules a day with a large glass of water, preferably following the guidance of a qualified health professional, without exceeding the recommended dose.
No timing is imposed. Many prefer to take it with dinner or late in the day, so it becomes an evening marker; those taking two capsules usually split them morning and evening. What makes the difference is daily consistency.
Plan a two to three month routine. A box of 60 capsules covers two months at one capsule a day, one month at two — which is why many order several boxes at once. Store the product in a cool, dry place away from light, and check that the seal is intact on delivery.
