The magnesium your body actually uses: science, dosage, and differences that matter

Magnesium is one of those minerals that we take for granted.

We hear it in advertisements, in supplements, on social media… but rarely is something fundamental explained: not all magnesium is the same , nor does the female body use it in the same way.

And that's where the problem begins.

Why magnesium matters so much in the female body

Magnesium is involved in more than 300 biochemical reactions : from energy production (ATP) to muscle relaxation, hormone synthesis, and the regulation of the nervous system.

In women, their role is even more critical:

• During the luteal (pre-menstrual) phase , magnesium levels tend to drop, which aggravates symptoms such as irritability, fatigue, or anxiety.

• During periods of high stress or poor sleep quality , magnesium is depleted more quickly due to chronic activation of the HPA (hypothalamic-pituitary-adrenal) axis.

• In athletes or active women , it is lost through sweating and accelerated metabolism.

In summary: women have a higher risk of functional deficit , even with balanced diets.

The common mistake: thinking that “any magnesium” will do

Most supplements on the market use cheap and poorly bioavailable forms (such as magnesium oxide).

The body only absorbs about 4–5% that way.

That's why we designed a formula that combines three complementary types of magnesium , with different functions and absorption rates, to cover the neurological, muscular, and cellular aspects.

SANA's smart combination: three forms, three ways of action

Shape	Main action	Characteristics
Magnesium Bisglycinate	Muscle and nerve relaxation	Chelated form with glycine, highly bioavailable and gentle on the digestive system. Promotes calmness, rest, and muscle recovery.
Magnesium Citrate	Metabolic and digestive balance	Highly absorbable organic form. Promotes enzyme function, energy metabolism, and helps regulate intestinal transit. Its acidic profile improves magnesium bioavailability and cellular utilization.
Magnesium Acetyl Taurate (ATA Mg®)	Cognition, mood, and neuronal protection	Patented formula. The only magnesium that effectively crosses the blood-brain barrier. Supports neurotransmitter synthesis and protects against oxidative stress in the brain.

ATA Mg® — the magnesium that reaches the brain

Magnesium Acetyl Taurate (ATA Mg®) combines magnesium and taurine —an amino acid with neuroprotective properties— forming a stable and highly lipophilic complex.

This allows magnesium to cross the blood-brain barrier , something that common forms cannot achieve.

Studies show that ATA Mg®:

• Improves mitochondrial function in neurons.

• It increases the concentration of intracellular magnesium in the brain.

• It reduces neuroinflammation and stress-induced anxiety.

• It promotes memory and synaptic plasticity.

In women, this effect is especially relevant: cyclical hormonal changes alter the availability of magnesium in the brain, affecting the balance between GABA and glutamate—the neurotransmitters of relaxation and arousal. ATA Mg® helps restore this balance.

Optimal dosage and synergies

The recommended doses of magnesium for adult women range between 300–400 mg/day , although in situations of stress, training or luteal phase higher amounts may be needed (up to 500 mg/day).

SANA's Triple Magnesium contains a total of 375 mg of elemental magnesium, distributed among the three forms in physiologically effective proportions:

• 45% bisglycinate

• 35% citrate

• 20% acetyl-taurate

This combination ensures gradual release and total absorption of over 90%, according to available literature.

What you can notice (based on the evidence)

The most frequently reported benefits of combined and bioavailable supplementation include:

• Less physical and mental fatigue.

• Less premenstrual tension.

• Better sleep quality.

• Greater mental clarity and a sustained sense of calm.

• Reduction of muscle cramps or cervical stiffness.

In summary

Magnesium is not just another supplement.

It is the mineral of stability : nervous, muscular, energetic and hormonal.

And when used correctly — designed for how the female body works — it stops being “a relaxing pill” and becomes a real tool for biological regulation.
