Magnesium plays established roles in the nervous system, including in nerve signalling and the communication between nerves and muscles. It contributes to normal nervous system function and normal psychological function, which reflects how important it is to the way the brain and nerves work day to day.
For a fuller overview of forms, dosage and safety, see our Magnesium Supplements Guide.
How Magnesium Works in the Nervous System
Within neurons, magnesium acts as a natural regulator at NMDA receptors, moderating calcium entry and helping to keep excitatory signalling within normal bounds. This regulatory role is why magnesium is often discussed in the context of calm rather than stimulation.
Laboratory research suggests magnesium may also interact with GABA receptors, part of the brain's main inhibitory system. Most of this evidence comes from laboratory and animal studies, and how much it matters for a healthy person's mood or concentration is not well established.
Why the Bisglycinate Form Matters Here
Magneva's bisglycinate formulation is magnesium bound to glycine, an amino acid that itself acts as an inhibitory neurotransmitter. Chelated forms are generally better absorbed than magnesium oxide, and bisglycinate is often reported to be gentle on digestion. It has not been shown to be better absorbed than magnesium citrate.
Because magnesium is a nutrient you need every day, a form you can take regularly without stomach upset is a practical choice. Magneva also includes vitamin B6, which contributes to normal psychological function and to normal nervous system function.
What to Expect
Magnesium contributes to normal psychological function and to the reduction of tiredness and fatigue. A supplement is most relevant when your diet does not supply enough; if your intake is already adequate, extra magnesium may make little noticeable difference.
Individual experience varies considerably depending on baseline dietary intake, age, activity levels and overall health.
Who Might Consider Magneva
Magneva is intended for adults wanting nutritional support for normal nervous system and psychological function. It may suit people whose diets are low in leafy greens, nuts, seeds, legumes and whole grains.
If you have a diagnosed neurological or mental health condition, or take any prescription medication, consult a qualified healthcare professional before use. If you are experiencing persistent low mood, anxiety or memory changes, please speak to a doctor rather than relying on supplementation.
Safety
- The NIH upper limit for magnesium from supplements is 350 mg a day for adults. Magneva provides 350 mg, so do not take it alongside other magnesium supplements.
- Possible side effects include loose stools, nausea and stomach cramps.
- If you have kidney disease, speak to your doctor first.
- Magnesium can reduce the absorption of some antibiotics (tetracyclines and quinolones) and bisphosphonates. Separate them as your doctor or pharmacist advises.
In Summary
Magneva delivers 350 mg of elemental magnesium (from 1,590 mg magnesium bisglycinate) with 1.9 mg vitamin B6 in one vegan tablet a day, in a generally well-tolerated chelated form made under an FSSAI licence. Its role is nutritional support for normal nervous system and psychological function.
