"VERY IMPORTANT" is how Khalsa describes this energizing antioxidant. "It works on different areas of the brain and increases mental energy," he says. "It makes you more alert." According to Gonzalez, current studies are looking at whether high doses (up to 1,200 mg daily) can help patients with early-stage Parkinson's disease, a degenerative condition in which impaired delivery of dopamine in the brain affects movement. Khalsa cites an earlier study that found some benefit at doses of 1,200 mg daily, especially when combined with at least 100 mg of alphalipoic acid, a cell nutrient.
HOW to use it: For better energy and prevention of cognitive decline, Khalsa suggests taking 100 to 300 mg per day; you should triple that dosage if memory loss has already occurred. Patients taking statins should supplement, he adds, since the drugs deplete the body's store of coenzyme Q10.
