What it does in your body
Vitamin B6 (pyridoxine hydrochloride) is a water-soluble vitamin essential for normal nervous system function.
Involved in over 100 enzymatic reactions, primarily the synthesis of neurotransmitters.
The body does not store it, it needs to come from food or a supplement every day.
Natural source:
Vitamin B6 is found in chicken, fish, bananas, potatoes, avocado and nuts. Pyridoxine hydrochloride is the stable and well-researched form of B6 used in dietary supplements.
Why vitamin b6 is in Corti-Glow
Why this ingredient specifically, not an alternative.
B6 is essential for the synthesis of serotonin, dopamine and GABA, the neurotransmitters of good mood.
Many women have a mild B6 deficiency, especially under chronic stress or with hormonal contraceptives.
1.4 mg in one sachet covers 100% of the Reference Daily Intake (RDI) — exactly what is needed.
How it works on the body
Mechanism, step by step.
1Serotonin synthesis
B6 is a cofactor in the conversion of tryptophan → 5-HTP → serotonin. Without it, low mood.
2GABA synthesis
Also a cofactor for glutamate decarboxylase, the enzyme that makes GABA (the calm neurotransmitter).
3Regulation of hormonal activity
Vitamin B6 contributes to the regulation of hormonal activity — an authorized health claim (EFSA), important in the days before your cycle.
4Hemoglobin production
Participates in hemoglobin synthesis, directly related to energy and concentration.

How it works with the other ingredients
7 ingredients. Each pair with a specific mechanism.
Not random supplements in one box. Every combination has a biological reason.
Combination
Vitamin B6 + Myo-Inositol
+ Myo-Inositol · 2000 mg
For cycle and sugar cravings
Mechanism
Vitamin B6 contributes to normal psychological function (authorized claim, EFSA), while myo-inositol (2000 mg) is among the most-studied ingredients for the days before your cycle. Low mood then comes from two fronts — hormonal and mental.
End benefit
A more stable mood in the luteal phase (the second half of the cycle). Less of an “impossible” week.

Frequently asked questions
About vitamin b6.
Isn't 1.4 mg too little?+
1.4 mg is 100% of the Recommended Daily Allowance (RDA). The high doses (50–100 mg) in trials are therapeutic, for PMS. In Corti-Glow the dose is for daily maintenance. If you have severe PMS, consult a doctor about a higher standalone dose.
What is the effect of B6 for women?+
Vitamin B6 contributes to the regulation of hormonal activity and to the reduction of tiredness and fatigue. Those are its authorised EU claims, and beyond them we will promise you nothing.
Can there be too much B6?+
Yes, over 200 mg daily for months can cause neuropathy (tingling in the hands/feet). 1.4 mg is a safe dose for daily intake.
