Inositol.
Inositol or myoinositol is a biological molecule found on the external layer of  cell membranes. Although its chemical structure is very similar to vitamin B complex, it is not classified as such, because it is synthesized in the human body. Thus, inositol is not considered essential for the function of organs or systems. Nevertheless, inositol has been traced in all tissues and significant concentrations in heart, lens of the eye and brain have been measured.
Inositol helps the liver to process fats, since, along with choline, it contributes to formation of lecithin, a phospholipid that is necessary for the above procedure.
It has been reported that inositol prevents excessive hair loss and it helps in nerve transmissions, cell membrane function, estrogens release, cholesterol control and muscle function.
Inositol has been recommended and used with a quite wide range of effects in treatment of mental and behavioral conditions, such as obsessive-compulsive disorder, depression, anxiety, bipolar disorder, panic disorder, Alzheimer's disease and attention deficit disorder. It has also used with controversial results in treatment of insomnia, liver medical problems, constipation, diabetic neuropathy, eczema and in prevention of cancer.
Sources of inositol.
Inositol is contained in seeds, beans, lentils, nuts, whole grains, chickpeas, wheat, cantaloupe, oranges, citruses, bananas, brown rice, oat flakes, raisin, molasses, brewer's yeast and liver.

Inositol deficiency and toxicity.
This can occur after prolonged antibiotic courses, heavy coffee drinking and because of a diet low in inositol. There are some indications that inositol deficiency may be related to diabetes, anxiety and depression. Increased bad cholesterol level, eyes disorders, eczema, constipation and excessive hair loss may be signs of inositol deficiency.
No toxic effects have been reported but diarrhea is quite likely to occur in excessive dosage of inositol.
Recommendations for inositol.
Supplementation dose is usually 500mg on a daily basis, although, under certain circumstances, physicians may recommend up to 500mg twice a day. No RDA has been specified for inositol.
No significant clinical side-effects have been identified, even when a therapeutic dosage of inositol reaches a level equivalent of fifteen times the normal daily intake. However, increased dosage of the nutrient may impair the absorption of iron, calcium and zinc.
Safety has not been established in young children, pregnant or breastfeeding women and people with severe liver and renal conditions.
In general, inositol supplementation is not considered necessary for preventive purposes in healthy people. |
