Myo-inositol is a key cell membrane component and messenger in our neuro-communication system that signals release of serotonin and norepinephrine.* It also triggers other cell functions related to glucose and fat metabolism.* Controlled clinical trials using several grams of inositol daily have shown a positive benefit on mood and emotional stability in specific clinical applications.* Each 1/4 teaspoon contains 700 mg of pure myo-inositol with no added ingredients.
