A daily intake of 50 to 100 milligrams of Coenzyme Q10 is appropriate for all adults under 60, states Dr. Sinatra. While there is no official recommended daily value, individuals taking a statin drug or seeking greater heart support can take 100 to 200 milligrams daily.
CoQ10 is a naturally occurring antioxidant synthesized inside the body, which is also found in many foods. Available as a supplement, CoQ10 comes in two forms: ubiquinol, the antioxidant form, and ubiquinone, the oxidized form that is later converted into ubiquinol, states Dr. Weil.
CoQ10 production declines with age, so increased dosages upward of 300 milligrams may be beneficial for adults over the age of 60, recommends Dr. Sinatra.
