Inositol

Inositol is a carbohydrate compound structurally similar to glucose and is sometimes referred to as vitamin B8, though it is not officially recognized as a vitamin. Widely found in foods such as fruits (especially cantaloupe and citrus), beans, grains, and nuts, inositol also occurs naturally in the human body where it is involved in cell signaling and the function of neurotransmitters. Supplement makers typically use myo-inositol, the most abundant form, sourced either through fermentation or extraction from plant sources. In supplement formulas, inositol is valued for its potential to support mental clarity, emotional balance, and relaxation without being a stimulant. It is commonly included in blends targeting brain health, stress management, and metabolic support. When reviewing a supplement label, check for the specific form and dosage to ensure it suits your intended use, as inositol may be combined with other nutrients to maximize its effects.
