Pseudovitamin B8 is added to multivitamins for its potential improvement of mood.
Formerly referred to as vitamin B8, inositol is naturally produced by the body and involved in multiple processes, the most important of which is:
- Cell signaling. Inositol is a component of several messenger molecules that help control key cell processes such as growth.
Vitamin B8, or inositol, as it’s more correctly called, was once a part of the vitamin B family. The classification has long been retracted since vitamin B8 was shown to be produced by the body from glucose, and thus not truly an essential nutrient.
Inositol is a sweet-tasting compound that exists in 9 different forms, the most relevant one being myo-inositol. In addition to its endogenous (inside the body) production, most people consume inositol in common foods such as citrus fruits, dairy, beef, whole grain breads, and dark leafy greens such as spinach.1
Inositol plays a big role in cell signaling—the communication between cells and various molecules that influence their function—and is also an indispensable part of nerve, brain, and muscle function. It has also been used by medical practitioners for an array of purposes, including breaking down fat, increasing insulin sensitivity, and decreasing liver problems, although it seems to be added to multivitamins mainly for its ability to enhance mood.
