The B-vitamin family is big. Niacin, thiamin, riboflavin, and folic acid are all members you’ve surely heard of. But what about inositol?
Considered a part of the vitamin B-complex, inositol is found in meats, citrus fruits, nuts, beans, and whole grains, and is also produced by the body. It’s a fundamental ingredient of cell membranes and is necessary for healthy nerve, brain, and muscle function. Inositol is also essential in the communication that occurs between the body’s cells.
Studies show that inositol may help improve mood. One double-blind controlled study found that 12 grams of inositol daily for four weeks showed significant benefits for depressed patients, compared to placebo. Other studies show that it may help with hair growth, nerve function, weight loss, and healthy cholesterol.
Although deficiency is uncommon, heavy consumption of caffeine, or the use of some antibiotics, may cause a shortage of inositol in the body. There is no RDA for inositol, but it’s generally recommended that 500mg be consumed daily.
