What is Inositol (Vitamin B8)?

Inositol, also referred to as Vitamin B8, is a water-soluble fatty lipid that is necessary for the formation and maintenance of healthy cells. It is classified as a nonessential nutrient because it can be synthesized by intestinal bacteria within the body from glucose.

Inositol directly precedes phospholipids (Wikipedia), a major component of cell membranes. It ensures proper electrical energy and nutrient transfer across the cell membrane. It also has lipotropic capabilities acting in the export of fats from the liver

Inositol is found in many foods - in cereals with high bran content, nuts, beans, meats, and in whole grains and fruit, especially cantaloupe and oranges.

The body needs inositol in small amounts daily to stay healthy. The most common natural form of it is myo-inositol. Inositol is present in all body tissues, with the highest concentrations in the brain, heart and lens of the eye.

Deficiency is rare. The body manufactures inositol and it is present in a wide variety of foods. However, long term use of antibiotics increases the need for inositol.

Caffeine destroys and depletes this nutrient. High caffeine intake can lead to deficiency. Those who use caffeine products often may want to consider inositol supplementation.

Benefits of Inositol

Inositol plays a role in the health of cell membranes especially the specialized cells in the brain, bone marrow, eyes and intestines. The main task of the cell membranes is to filter and regulate the contents coming in and out of the cells to ensure healthy function.

Inositol triggers the release of calcium in cells. It also acts in the movement of fats within cells. Its most important role seems to be in the central nervous system, where it serves to help transmit messages between neural cells along neural pathways. Inositol appears to be available in greater concentration in the cells in and around the central nervous system, including brain cells and retinal cells, and in other specialized cells such as bone marrow and intestinal cells. It is also found in high concentration in mother’s milk.

Purity and Concentration of Inositol

This pharmaceutical-grade carbocyclic polyol inositol contains no fillers, additives or anti-caking agents.

Potential Side Effects of Inositol

Inositol is safe at suggested serving sizes. Side effects, including nausea, vomiting, dizziness and headache, are generally seen only at higher serving sizes.

To avoid side effects do not take more than the recommended serving size (a scant 1/4 teaspoon) unless directed to do so by a qualified health practitioner.

This product is not recommended for use by pregnant women or those with ADD, ADHD, and schizophrenia.

Suggested Use of Inositol

The suggested serving size for inositol is 500 milligrams taken twice daily, depending on individual needs. You can see the full bulk density/volumetric conversion chart for Inositol here. A serving size of 1/4 teaspoon is equal to 684 milligrams (mg), so a "scant" 1/4 tsp will give about 600 mg. Similarly, a serving size of 3/16 teaspoon will equal 513 mg.

When using inositol, choline, a lipotropic that supports the B vitamin complex, should be taken in the same amount.
