Tense all day, wired at night, tired the next morning?
Maybe you have tried magnesium before and felt nothing, or felt it mostly in your stomach. MAG-COMPLEX puts four forms in one capsule: the gentleness of some, the strength of others. In the evening the tension eases, the night gets quieter, and the next day starts with energy to spare.
- ✓ Contributes to the normal function of the nervous system and to normal psychological function — the foundation of demanding days
- ✓ Contributes to normal muscle function — for muscles that stay tight at the end of the day
- ✓ Contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism, morning to night
- ✓ Four forms, not one: easier on the stomach than a single, heavily dosed form

Magnesium, in plain terms
What is MAG-COMPLEX 400 mg?
MAG-COMPLEX is Alphavital’s magnesium complex: 400 mg of magnesium per capsule, split across four forms (bisglycinate, citrate, marine and oxide) inside a 100 % vegetable capsule made from cellulose. One box holds 60 capsules (net weight 24 g).
Your body cannot make magnesium; it has to come from food. White bread, coffee, high-pressure weeks, training and the sweat of a Moroccan summer all eat into that supply.
Each form has its own strength: bisglycinate and citrate are gentle on digestion, marine and oxide bring more magnesium per milligram. Alphavital chose to combine them instead of picking one. Four forms in one capsule means the intake is spread out and easier on the stomach.
In practice, this is the magnesium for packed days and short nights. Sleep badly and the next day starts tired; let the tension drop in the evening and mornings feel lighter, with energy that lasts into the evening.
The actives and their role
| Component | Per capsule | Role |
|---|---|---|
| Magnesium bisglycinate | 100 mg | A chelated form bound to glycine, valued for how gently it sits in the stomach. |
| Magnesium citrate | 100 mg | An organic magnesium salt studied for its good absorption. |
| Marine magnesium | 100 mg | Magnesium of marine origin, naturally accompanied by other minerals. |
| Magnesium oxide | 100 mg | A mineral form concentrated in elemental magnesium. |
| Total magnesium | 400 mg | Four forms combined for a gradual intake and better digestive tolerance. |
| Vegetable capsule (cellulose) | — | A 100 % plant-based shell, free from animal gelatine. |
| Magnesium stearate (plant origin) | — | A plant-derived processing aid that keeps the dose consistent from one capsule to the next. |
The components are listed exactly as they appear on the box, with nothing undeclared added.
How does magnesium act on nerves and muscles?
Magnesium is a cofactor in several hundred enzymatic reactions across the body: cellular energy production, protein synthesis, nerve impulse transmission, and the contraction and release of muscle. That conductor’s role is summarised in a reference review published in Scientifica (Schwalfenberg & Genuis, 2017).
On the nervous side, a systematic review published in Nutrients examined the body of work on magnesium, subjective anxiety and stress; it reports encouraging signals while calling for better-controlled trials (Boyle et al., 2017, Nutrients). Magnesium has also been the subject of a controlled trial in older adults reporting difficulty falling asleep (Abbasi et al., 2012, J Res Med Sci) — research presented here for information, not as a promise of results.
Why four forms rather than one? Because no two magnesium salts behave alike. The bioavailability of magnesium citrate was compared with other preparations in a randomised, double-blind study (Walker et al., 2003, Magnesium Research), while marine-derived magnesium sources have been assessed for bioaccessibility and digestive tolerability (Dowley et al., 2024, Methods). By bringing bisglycinate, citrate, marine and oxide together, MAG-COMPLEX plays on complementarity: the gentleness of chelated and organic forms, the concentration of mineral ones.
What EU law on health claims (Regulation (EU) No 432/2012) allows, finally, is clear and sufficient: magnesium contributes to the normal function of the nervous system, to normal muscle function, 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. Nothing more, nothing less: a food supplement accompanies a varied diet and a balanced lifestyle, it does not replace them. To explore neighbouring formulas, the Serenity & Sleep and Vitamins & Minerals sections gather the rest of the range. If you would rather have one very gentle form for the evening, see our Magnesium Glycinate, and our guide to magnesium forms explains what sets each one apart.
What you are looking for, and what supports it
| This sounds like you if… | What magnesium contributes to |
|---|---|
| Your days run back to back under pressure and winding down at night is hard | Contributes to the normal function of the nervous system and to normal psychological function |
| Your muscles stay knotted and your legs feel heavy after effort or late in the day | Contributes to normal muscle function and to electrolyte balance |
| After a short night you wake up tired, and energy is missing from the morning on | Contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism |
| You train hard, you sweat a lot, or the heat weighs on your intake | Contributes to electrolyte balance and to normal protein synthesis |
| Standard magnesium supplements sit heavily on your stomach | Four forms combined — including bisglycinate, valued for its digestive gentleness — instead of a single form |
| You want to know exactly what you are taking | 400 mg per capsule, four forms declared to the milligram, a vegetable capsule, and an ONSSA certified product |
How to use it
Take 1 to 2 capsules a day with a large glass of water, preferably following the guidance of a qualified health professional, and without exceeding the recommended dose.
Most people take it late in the day or with dinner: the majority feel the relaxation about 30 minutes after the first capsule, just in time for the evening. On two capsules, one in the morning and one in the evening works too. What counts is consistency.
Plan for a two to three month routine. A 60-capsule box lasts two months at one capsule a day, one month at two. Store it in a cool, dry place away from light, and check that the seal is intact on delivery.
The Alphavital transparency certificate
Batch-by-batch control consistent quality from one box to the next, in line with the sanitary safety standards in force.
A formula declared to the milligram bisglycinate 100 mg, citrate 100 mg, marine 100 mg, oxide 100 mg — that is 400 mg of magnesium per capsule, exactly as printed on the box.
100 % vegetable capsule a cellulose shell, free from animal gelatine; the only other ingredient is plant-origin magnesium stearate.
Seal and storage every box is sealed; store in a cool, dry place, out of reach of children.
