No known specific symptoms of deficiency
As with all other nutrients, a wide variety of foods, preferably for the most part unrefined, is the best health protection. It would be difficult to develop an inositol deficiency without also developing a number of other deficiencies.
Inositol is found in cereals (particularly the bran portion) and vegetables in the form of phytic acid, a combination of inositol with phosphorus.
In research studies, inositol supplements have been found to:
- Improve diabetic neuropathy
- Reduce symptoms of clinical depression and anxiety
Preferred form and suggested intake
The usual form of inositol supplementation is lecithin, which contains large amounts of inositol. Lecithin can be bought in granules and sprinkled on food or in hot drinks. The usual dosage is 1-2 tablespoons per day.
There is no known unsafe dosage of lecithin.
