Ubiquinol supplement health benefit, dosage, comparison to ubiquinone by Ray Sahelian, M.D. Is it superior to CoQ10? What is the right dosage, how often should you take it?

Ubiquinol is the reduced form of coenzyme Q10. Long term human research regarding its benefit versus regular CoQ10 have not been done, therefore it is premature to make any claims that a ubiquinol supplement is preferable to regular CoQ10 supplement or vice versa. There have been hundreds of studies in humans with CoQ10 and hardly any with ubiquinol. This does not mean the latter is not of medical benefit, we just don't know as much about it yet.
   CoQ10 cycles between ubiquinone and ubiquinol in the production of energy in mitochondria.

Buy Ubiquinol pills

Buy Ubiquinol 50 mg or Coenzyme q10 products of high quality.

The owner of the health food store where I buy my supplements is a pretty knowledgeable guy and when I stopped there today to pick up more CoQ10 he said he was pushing the folks that buy CoQ10 towards ubiquinol. The small print on the bottle says it is a reduced form of CoQ10 for enhanced absorption. Do you think it is indeed as good as (or maybe better) than CoQ10 as an antioxidant / energy enhancer (what I use it for) or a cholesterol lowering / diabetes controlling supplement (what my husband uses it for...we both take 50 mgs/day, 7 days a week.
   It's going to take a few years of additional clinical trials before we can be more knowledgeable regarding their benefits and differences.

Role in animals
Ubiquinol is the two-electron reduction product of ubiquinone (coenzyme Q10 or CoQ10 and functions as an antioxidant in both mitochondria and lipid membranes. In humans and most mammals, including dogs, the predominant form of coenzyme Q is coenzyme Q10, whereas the primary form in rodents is coenzyme Q9 or CoQ9.

Safety, side effects, risk, danger
Study on safety and bioavailability of ubiquinol (Kaneka QH) after single and 4-week multiple oral administration to healthy volunteers.
Regul Toxicol Pharmacol. 2007. Pharmacology and Toxicology Group, Life Science Research Laboratories, Kaneka Corporation, 1-8 Miyamae-machi, Takasa-cho, Takasago-shi, Hyogo, Japan.
The safety and bioavailability of ubiquinol, a naturally occurring lipid-soluble nutrient, were evaluated for the first time in single-blind, placebo-controlled studies with healthy subjects after administration of a single oral dose of 150 or 300mg and after oral administration of 90, 150, or 300mg for 4 weeks. No clinically relevant changes in results of standard laboratory tests, physical examination, vital signs, or ECG induced by ubiquinol were observed in any dosage groups. Following single or multiple-doses of ubiquinol in healthy volunteers, significant absorption of ubiquinol from the gastrointestinal tract was observed, and no safety concerns were noted on standard laboratory tests for safety or on assessment of adverse events for doses of up to 300mg for up to 2 weeks after treatment completion.

Studies and research
Ubiquinol and the papaverine derivative caroverine prevent the expression of tumour- promoting factors in adenoma and carcinoma colon cancer cells induced by dietary fat.
Biofactors. 2005.
High consumption of dietary fat promotes colon carcinogenesis. While this effect is well known the underlying mechanism is not understood. Fatty acid hydroperoxides (LOOH) arise from unsaturated fatty acids in the presence of oxygen and elevated temperature during food processing. An approach was made starting from the assumption that LOOH are present in dietary fats as a result of boiling. LOOH undergoes homolytic cleavage in the presence of iron. We studied their effects on gene expression in colorectal tumour cells using linoleic acid hydroperoxide (LOOH) as model compound. Addition to the medium of LT97 adenoma and SW480 carcinoma cells enhanced the production of hydrogen peroxide. Both cell lines were observed to increase VEGF and COX-II expression based on mRNA. Expression of VEGF was inhibited by caroverine and ubiquinon.

Questions
Q. I read your article on coenzyme Q10, and was wondering what your thoughts are about an article on ubiquinol on the Life Extension Foundation website that claims this, "In what may be the most significant breakthrough in the history of the dietary supplement industry, Japan’s largest CoQ10 producer has discovered a way to deliver the highest concentrations of the most biologically active form of coenzyme Q10 to the bloodstream. This improved form of CoQ10 not only absorbs up to eight times better, but also has demonstrated unprecedented anti-aging effects compared to placebo and compared to the coenzyme Q10 you are using now. This novel CoQ10 compound ubiquinol could revolutionize how a number of age-related disorders are both prevented and treated. In order for the ubiquinone form of CoQ10 to be properly utilized, it first must be reduced in the body to its active metabolite known as ubiquinol. While most ubiquinone is naturally reduced to ubiquinol, the optimal way to supplement with CoQ10 would be to ingest it in its ready-to-use ubiquinol form. After years of painstaking research, Japan’s largest producer of coenzyme Q10 has developed a patented method to stabilize ubiquinol so that it can be swallowed in a capsule for utilization by cells throughout the body. The ramifications of widespread use of this novel form of CoQ10 are profound. For the first time, it may be possible to achieve the sustained high blood levels of biologically active ubiquinol CoQ10 needed to delay certain manifestations of aging and its related disorders."
   A. In order to make claims that a particular supplement is better than another version, human studies have to be done head to head for at least a few months or preferably a few years. Such studies have not been done with ubiquinol and CoQ10. Hence, the claims made above are premature and appear to be more marketing than science. We are not saying that ubiquinol is not beneficial. We are just saying that it is premature to make any such claims when not even one good human study has been done, and it appears that the claims are being made by those who want to sell ubiquinol. It is possible that too high a dose of ubiquinol in the body may actually be harmful or throw body chemistry off balance.

Q. I noticed that your webpage about ubiquinol states that there have been no studies indicating that health benefits of ubiquinol might be superior to ubiquinone.
There is a Cardiologist, Peter Langsjoen, MD, in Tyler, TX, who has been studying CoQ10 and recently conducted a clinical trial, supplementing ubiquinol, in patients with CHF, with very impressive results. Perhaps there are no head to head clinical studies directly comparing ubiquinol to ubiquinone yet, but the results Dr. Langsjoen reports considerably exceed beneficial effects previously observed with ubiquinone supplementation. The article says, "Ubiquinol, only available in supplement form since late 2006, is the active antioxidant form of Coenzyme Q10. CoQ10, a vitamin-like substance found in every cell in the body, plays a vital role in cellular energy production and protects cells from free radical damage. In the first clinical trial evaluating ubiquinol effects on late-stage congestive heart failure, cardiologist Peter Langsjoen found that critically ill patients who supplemented with ubiquinol for just three months experienced a 24 to 50 percent increase in their hearts' ability to pump blood. In some cases, patients' plasma levels of CoQ10, which are key to overall heart health, more than tripled. At the start of the study, each of the patients evaluated had a life expectancy of less than six months. However, all demonstrated significantly improved heart function by the trial's end, and survived past initial expectations.
   A. It would be helpful to see a head to head comparison.
