Jarrow Formulas Inositol is a dietary supplement containing pure pharmaceutical-grade inositol. The powder form ensures an easy and convenient dosage. Inositol shows many positive properties for the body, e.g. it supports fat and carbohydrate metabolism, normal liver function and may improve hormonal and metabolic parameters in women with polycystic ovary syndrome (PCOS).
Inositol, also known as vitamin B8, belongs to the group of vitamin-like substances – compounds with similar effects to vitamins. Inositol occurs in the form of several isomers, of which myoinositol is biologically active.
An essential component of cell membranes
Inositol is part of phospholipids, and more specifically – phosphatidylinositol, which is a component of cell membranes, including brain and liver lipids. Inositol is believed to help in supporting cognitive functions and improving mental well-being. It may also have a protective effect on the liver.
Optimal glucose and insulin metabolism
Inositol in the form of inositol triphosphate (IP3) is a second signaling molecule, transmitting, among others, insulin signal. IP3 results from the cleavage of phosphatidylinositol diphosphate present in cell membranes. Inositol indirectly leads to increased expression of GLUT-4 glucose transporters, which are found, among others, in muscle tissue and are dependent on the action of insulin. This leads to an increase in glucose uptake from the bloodstream and, consequently, to a lowering of sugar levels and reduction of insulin resistance.
Help in the fight against PCOS
Polycystic ovary syndrome is one of the most common causes of menstrual disorders and infertility in women. PCOS is usually accompanied by insulin resistance. Inositol, by improving glucose-insulin metabolism, supports the regulation of hormonal and metabolic parameters in PCOS. It may also restore proper ovarian function and reduce symptoms such as hirsutism, as proven in numerous clinical studies.
In summary, Jarrow Formulas Inositol is a preparation recommended primarily to improve insulin sensitivity, as an adjuvant in impaired glucose tolerance, to women with PCOS, to improve cognitive functions and well-being, as well as to support liver health.
Inositol dissolves in water and is considered a safe, nontoxic substance which can be used for a long time. It is worth knowing that caffeine depletes the body of inositol. As a result, individuals drinking two or more cups of coffee daily are particularly susceptible to deficiency.
The recommended daily dosage is from 200 to 4000 mg. It is recommended to divide it into 2-3 doses and take them at intervals of several hours. For the best absorption, the supplement should be taken during a meal. The powder has a pleasant, naturally light sweet flavour. You can dissolve it in water and drink it.

Inositol is an organic compound from the group of B vitamins soluble in fluids, present in the natural or synthetic form, synthesized in plants, such as brewer's yeast, beans, grapefruit, cabbage, sprout of wheat, melons and animal (liver). Along with choline is included in the lecithin. It affects the cell nutrition of the central nervous system (brain) by reducing the level of LDL (bad cholesterol), this makes it applicable in treatment of Alzheimer's disease and atherosclerosis. It has a calming effect. There has been a beneficial effect of inositol on the skin and hair reported.
Myo-inositol - the most frequent naturally occurring stereoisomer of inositol, a 6-carbon sugar with pro-health properties, also called vitamin B8. Its sources in food are mainly citruses, legumes and nuts. Human organism has the ability of its endogenous synthesis, it is the component of phosphatidylinositol, which is a precursor for some hormones (including insulin) and secondary transmitters responsible for processing intercellular signalization.
Supplementation with myo-inositol demonstrates the ability to increase insulin sensitivity, thanks to which it may be successfully used by people dealing with insulin resistance. It also reduces hyperandrogenemia. Due to these scopes of effectiveness, myo-inositol is recommended to women with polycystic ovary syndrome and it is indicated as the most effective form of reducing the symptoms of PCOS. It is conducive to proper menstrual cycle.
Moreover, myo-inositol demonstrates positive influence on mental functions. It is conducive to well-being, may have anti-depressant effect and reduce anxiety attacks. For this reason, it is used as an additive to energy drinks.
For therapeutic purposes, myo-inositol is most frequently used with folic acid.
