Inositol Powderstar rating 5DeaFebruary 20, 2007Jarrow's Inositol Powder is part of my daily routine to combat depression which is due to a chemical imbalance that I haven't been able to correct with diet and exercise. It works beautifully. The powder form lets me adjust as needed . . . another big plus. Over time, I find I'm using less (was using 1 T, now use 1 t) and can use every other day. I first heard about Inositol for this in Christiana Northrup's The Wisdom of Menopause.
