Hello msteve666,
with regard to the need for supplementation & dosage of CoQ10, this is what Al Sears MD has to say, after he researched the nutrient at the The Wellness Research Foundation....................
"I suggest you supplement with a minimum of 100 mg a day. If you have high blood pressure, heart disease, high cholesterol, gingivitis, age related memory loss, chronic fatigue or are a vegetarian, increase your dose to 200 mg per day."
