The Difference Between CoQ10 and Ubiquinol

Question:
What is the difference between CoQ10 and ubiquinol?

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 contains fats or other 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.

For a long time, I took 100 mgs of Ubiquinol CoQ10 and I still had low levels when I had my blood tested. These supplements are just too expensive to take more than 100 mgs so I resorted to the cheap 300mgs CoQ10 from Costco. For the first time, I had higher than normal levels of CoQ10. Ubiquinol, for me, was a waste of money.

I gave plain old uniquinone with no absorption enhancer to adults between 55 and 70 years old (unpublished study). I told them to take it with a meal that had at least 170 Calories from fat. After 9 days, plasma levels of CoQ10 increased substantially. I did not compare to any of the established enhanced CoQ10 products. However, the plasma values I got looked fairly close to what people report with the "super" CoQ10 products.

What brand was it? jarrow sells powdered CoQ10 caps at a good price
Right now I'm taking Healthy Origins CoQ10 200 Mg. Was taking 100 Mg. before but the 200Mg. gives me more energy

I've tried Ubiquinol but for some reason it makes me feel strange

What I wonder about is the quantity of CoQ10 to be taking and when. Most of the supplements in your review are 100 mg with recommendations of 1 to 3 a day. With the Costco 300 mg being "the most bang for the buck," I'm wondering if that's the "best" way for an 80 year old man to go. Are there any significant trade-offs between taking 100 mg 3 times a day versus the 300 mg once a day, so long as it's taken after a meal that includes a reasonable amount of fat?
