Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical...

Ubiquinone is the form of Coenzyme Q10 that the body synthesizes, and ubiquinone is the form of Coenzyme Q10 that has been extensively tested for safety, absorption, and efficacy in clinical trials. More and the reduced form called ubiquinol. What do the terms oxidized and reduced mean? Basically, they are terms from chemistry. The oxidized form is the Q10 molecule that has donated electrons. The reduced form is the Q10 molecule that has accepted electrons. Together, the two forms make up a redox pair, and the point about a redox pair is that the body converts the two forms back and forth.
Lately, there has been a lot of advertising hype for the ubiquinol form of Q10.

Each Q10 molecule is like a light switch
In the human body, the Q10 molecules are oxidized and reduced repeatedly and are thus transformed back and forth multiple times. Each Q10 molecule is switched back and forth in the body in just the same way that a light switch is turned on and off, you could say.
Whichever form you take as a supplement to your diet, each Q10 molecule will change its form many times in the body before it wears out.

Dr. Sinatra’s study of Q10 absorption
The American cardiologist Dr. Stephen Sinatra, the founder of the New England Heart Center, was curious about the claims for the ubiquinol form of Q10. So, in 2013, he recruited 12 volunteers to participate in a Q10 absorption study. He measured the participants’ blood serum Q10 levels at the start of the study and at the end of each month of the study.
In the first month, he gave six participants 200 mg of ubiquinoneUbiquinone, the oxidized form of Coenzyme Q10, expressed as Q10 or CoQ10, is absolutely essential for the mitochondrial ATP energy production process.

More every day, and he gave the other six participants 200 mg of ubiquinol every day. In the second month, the participants got no Q10 supplements at all. Then, in the third month of the study, Dr. Sinatra switched the roles, and, each day, he gave 200 mg of ubiquinol to the first group and 200 mg of ubiquinoneUbiquinone, the oxidized form of Coenzyme Q10, expressed as Q10 or CoQ10, is absolutely essential for the mitochondrial ATP energy production process.

More to the second group.
At the end of the study, he found that all 12 of the study participants had achieved excellent increases in blood serum Q10 levels and that all of the participants had achieved approximately the same increased blood levels of Q10. He concluded that there was no good reason why he should begin recommending the more expensive and less stable form of Q10, the ubiquinol form.

Above it says “cut the capsule open and check the color. If you cut into a ubiquinol capsule and the liquid inside is yellow, then you know that you have paid extra money for ubiquinol that has already reverted to the ubiquinone form.”
I have a bottle Solgar ubiquinol capsules which I opened several months ago. When I cut one open today, it was milky but also yellow. I guess this means the ubiquinol is converting to ubiqinone as you descibe. Does this conversion only happen after the bottle has been opened or, assuming the bottle is within the expiry date, has it started to occur to any significant degree in a sealed bottle?
Hello, Ali,
Dr. Judy tells me that the ubiquinol, which is quite unstable by nature, is difficult to get into the capsules without at least some of its becoming oxidized. It has not been unusual for Dr. Judy to find oxidized Coenzyme Q10 in ubiquinol capsules.
It seems that people buy ubiquinol capsules primarily for one of two reasons: 1) they have accepted uncritically the marketing claims that ubiquinol is absorbed better than ubiquinone (not at all proven at this writing) or 2) they think that they need to take ubiquinol because the Coenzyme Q10 in the blood is predominantly in the reduced form. But the Coenzyme Q10 in both ubiquinone and ubiquinol capsules will be absorbed as ubiquinone in the small intestine and then converted to ubiquinol in the lymph.
Neither of the two reasons that I have listed above makes sense to me. There is only one producer of the ubiquinol raw material in the world today. There are a few competitors producing the ubiquinone raw material. Accordingly, the cost of the ubiquinol raw material is considerably higher on the world market than the cost of the ubiquinone raw material. And ubiquinol products are being marketed hard in the United States in these days (withut adequate documentation of solid research). It is a curious situation.
Thank you for your question, Ali. It provokes some thinking, you can see.
