In discussing their findings, doctors said that those who were most likely to have healthy hearts had CoQ10 levels of at least 516 nanomoles per liter of blood (nmol/L) or vitamin B6 levels of at least 59.7 nmol/L. This was not an “intervention” study, meaning doctors did not give participants any supplements to take, but instead observed the levels of CoQ10 and vitamin B6 already in the body. Doctors now suggest more study to help determine the exact benefits of giving CoQ10 and vitamin B6 supplements to those who are healthy, and those with heart disease, and to determine the most beneficial dose of these natural nutrients.
