Magnesium Bisglycinate · Magnesium bound to the amino acid glycine (chelated form)
The form of magnesium that actually reaches your brain, without upsetting your stomach.
Helps with
In plain language
Magnesium participates in over 300 biochemical reactions in the body.
The bisglycinate form = magnesium bound to two glycine molecules (an amino acid).
Glycine has a calming action on its own, and bisglycinate protects the stomach and reaches the brain more easily.
Natural source:
Magnesium is a mineral found in green leafy vegetables, seeds, nuts and legumes. The modern diet delivers it in insufficient amounts, 70% of Europeans are below the recommended intake. The bisglycinate form is bound to the amino acid glycine, the most bioavailable form for the brain.
Why magnesium bisglycinate is in Corti-Glow
Most people don't get enough magnesium from food, insufficient intake leads to difficulty falling asleep, cramps and tension.
The bisglycinate form does not loosen the stomach like oxide or citrate.
The glycine (from the bisglycinate) supports the GABA system, the same mechanism that calms the brain in the evening.
How it works on the body
Relaxes the muscles
Magnesium regulates calcium channels. Without it, muscles “hold” too much calcium, which is where cramps come from.
Supports GABA receptors
GABA (gamma-aminobutyric acid) is the calm neurotransmitter in the brain. Magnesium increases its sensitivity, the brain relaxes.
Regulates melatonin
Magnesium participates in the conversion of serotonin into melatonin, the sleep hormone. Without enough magnesium, melatonin is not produced optimally.
Reduces cortisol
Magnesium deficiency increases cortisol. Adequate levels keep the nervous system calm.

How it works with the other ingredients
Not just 7 supplements in one box. Every combination has a specific mechanism, here's why the formula is what it is.
Combination
+ L-Theanine · 200 mg
For calm focus without drowsiness
Mechanism
A classic synergy: L-Theanine increases the production of GABA (the calm neurotransmitter). Magnesium opens the GABA channels, the receptors that must “catch” GABA. Without magnesium, the increased GABA doesn't reach its target. Without L-Theanine, the opened channels have nothing to catch.
End benefit
A double calming effect, physical (muscle relaxation from magnesium) and mental (calm mind from L-Theanine).

The research
Abbasi et al. (2012)
Journal of Research in Medical Sciences
Participants
46 adults with insomnia
Dosage
500 mg magnesium daily, 8 weeks
Result: Significant improvement in sleep onset time (measured via a standardized insomnia index). Reduction in cortisol (the stress hormone).
Boyle et al. (2017)
Nutrients
Participants
Meta-analysis of 18 clinical trials
Dosage
Various forms, 150–500 mg
Result: Magnesium supplementation reduces subjective anxiety. The strongest effect is seen in individuals with a magnesium deficiency.
Schuette et al. (1994)
Journal of Nutrition
Participants
Controlled absorption study
Dosage
Comparison of forms
Result: The bisglycinate form showed the best absorption and the fewest side effects compared with oxide and citrate.
