This combination of coenzyme Q10, hawthorne (Crataegus oxycantha), potassium, taurine, & magnesium provides the heart muscle with nutrients for healthy functioning.* Co Q10 is a vital element for the heart.* Cells of the heart muscle have a high metabolism & need Co Q10 as an energy-producing cofactor.* Co Q10 also serves as an antioxidant.* Numerous studies on Co Q10 show its benefit in cardiovascular function.* In a 73-subject study with Co Q10 supplementation at 120 mg daily, improvements were observed after 28 days.* Taurine is an essential nutrient cofactor for cardiac function & the most abundant amino acid in the heart.* Research indicates supplementation with taurine supports already normal levels of cholesterol, probably due to taurine's ability to help convert cholesterol to bile acids.* In addition, taurine aids in the regulation of intracellular calcium levels, which helps protect the heart muscle & support cardiac function.* Flavonoid compounds in hawthorne appear to strengthen blood vessels & support cardiac function; whereas, flavonoids in Ginkgo promote blood flow.* Hawthorne has been shown to be supportive of good cardiac health by helping to maintain already normal blood pressure, heart rate, & exercise capacity.* The flavonoids in hawthorne & Ginkgo act as antioxidants & may improve artery function, which promotes dilation & blood flow.* Magnesium & potassium are minerals necessary for proper cardiovascular function.
