Great

It is a vitamin-like substance, aka vitamin B8. 10 years ago, a gynecologist prescribed it to me when planning a pregnancy, literally a month after taking it, I felt my ovulation, which was confirmed by ultrasound, after 3 months of taking it, I noticed how the quality of my hair changed and the pleasant bonus was that I lost weight in 3 months by 5 kg, although I didn't do anything else for this.I took it for about 6 months. 2 years ago, I started having health problems, I turned to a nutritionist and after passing tests, very low insulin and leptin were revealed, she diagnosed me with a violation of carbohydrate metabolism, I felt very weak, I did not feel full, after eating I constantly wanted to eat.The nutritionist picked up my nutrition and prescribed me to take at night starting with 1/4 teaspoon of inositol, this jar size was enough for me for a long time.

Neurotransmitter health

Inositol is very helpful for conditions such as anxiety, depression, and OCD. The body uses it in the manufacture of phospholipids required for neurotransmitters. If you are taking antidepressants or neurotransmitters such as 5-HTP, GABA, etc, you will find that inositol can enhance those. Dosing for those conditions is 12-18 grams per day.
