Inositol - from natural sources

How does it work?

Inositol works by helping the body use insulin, which is made by the pancreas then enters the bloodstream. Insulin is critical for our cells to take in glucose (sugar) and produce energy.

After a meal, the body breaks down glucose in the bloodstream. Increasing glucose in your blood tells your pancreas to make insulin. For insulin to work, it has to bind to the insulin receptor on the surface of the cell. When insulin binds to its receptor, it “unlocks” and releases secondary messengers. These secondary messengers tell the cell it is time to take in glucose from the blood.

So the nutrient, functions as a secondary messenger. Basically, they help the cell take in glucose from the blood. It is a messenger for serotonin and dopamine, these are neurotransmitters that send signals from the brain to other systems in the body. Low levels of inositol disrupt this signaling, maybe a factor in mood disorders and issues with mental health.

Inositol and Female Fertility

Inositol may also have fertility benefits for women, ample studies show that inositol normalizes menstrual cycles and helps restore ovulation.


Inositol benefits people with type 2 diabetes because of its effects on insulin signaling.

Inositol and PCOS

Inositol is an important supplement for women with PCOS (polycystic ovary syndrome).

Inositol can help address issues like failure to ovulate, high blood pressure levels, high triglyceride levels and high testosterone levels.
Myo-inositol can also help with promoting fertility and helping restore insulin sensitivity.

Inositol decreases testosterone levels and promotes regular menstruation and ovulation in women with PCOS.

There are various inositol doses that have been studied in scientific research. Dosage of inositol taken should be carefully considered with the condition for which it is needed. It's highly recommended to consult a health practitioner first before taking inositol and follow recommended dosages stated on the label of the supplement.

It is worth noting, that Dr. Abram Hoffer had much success with similar patients, using Inositol Hexanicotinate ( Niacin - B3)

In a 4-week, double-blind, crossover study (21 subjects), inositol at a dose of 12 gm per day and imipramine (a tricyclic antidepressant) were equally effective in reducing the frequency and severity of panic attacks in individuals diagnosed with panic disorder

Obsessive-compulsive disorder (OCD).
There is some research that shows that people with OCD who receive inositol orally for 2-3 months experience improvement.
