Answer: Only after you take CoQ10 (ubiquinone) does your body convert it to the active form, ubiquinol. Taking 100 mg of ubiquinol (sometimes labeled as CoQH-10 or CoQH2-10) compared to 100 mg of CoQ10, may yield a bit more active compound in your body. In short, you may be able to take a little less ubiquinol than CoQ10 to get the same result.
However, more important than whether you take CoQ10 or ubiquinol is that fact that both are fat-soluble compounds, so to significantly improve their absorption, it is important to take them with a fatty meal or in a formula that includes solubility enhancers.
More information about CoQ10 and ubiquinol and their solubility-enhanced formulas is found in the CoQ10 and Ubiquinol Supplements Review, which includes our test results and quality ratings of dozens of products, as well as ingredient and price comparisons.
