Neil was interviewed about CoQ10 for a trade magazine

* How would you rate consumer awareness of the health benefits of CoQ10? Neil: There is actually a fair amount of consistently positive press on CoEnzyme Q10 (CoQ10), with a significant part of that because of this antioxidant nutrient’s role in cardiovascular and heart health. Many cardiologists recommend CoQ10 to their patients and popular books, such as by Dr. Sinatra, promote the healthful effects of CoQ10 to at-risk people. I would go so far as to suggest that CoQ10 has picked up some of the wide popularity as a heart nutrient that vitamin E had several years ago (but lost due to consumer confusion caused by unwarranted negative publicity). The fact that CoQ10 is so obviously safe, versatile, and useful has propelled it to a high place on the list of cardiovascular nutrients. * What is driving consumer interest in CoQ10 products? Neil: The multiple roles of CoQ10 in the human body make it uniquely useful in protecting cells and energizing essential processes such as heart action and immunity. Energy supports the constant pumping of the heart muscle, but also supports immune functions and antioxidant activity. Lack of energy is a common complaint heard by doctors, and active people need good sources of energy, so nutrients that promise to improve the energetics of the body are always in demand. In addition, new technologies to improve the historically poor absorption of CoQ10 have expanded the product category as prices have moderated, which is a perfect place for people selling CoQ10 to be in. Tell us more about CoQ10: Neil: Ubiquinol doubles as an antioxidant, and like other antioxidants the body can convert from one to the other and back again. Although Ubiquinol lacks much in the way of human clinical trials, supplemental Ubiquinone mostly converts to Ubiquinol during transport from the gut to the circulatory system. Ubiquinol is the primary form of the nutrient that circulates in the body. Ubiquinol converts to Ubiquinone to stimulate the production of cellular energy. CoQ10 is a fat-soluble nutrient and therefore should only be taken with meals containing significant amounts of fat. That has traditionally been the main limiting factor in absorption. Blending CoQ10 into an oily base to make softgel capsules is somewhat superior to dry capsules because a little oil is provided, but again there just isn’t enough oil in a capsule to make a big difference when the nutrient is not dissolved into the oil. When CoQ10 is completely dissolved into an oil, forming a crystal-free solution, it does make it several times more absorbable. But all oily solvents are not created equal! Some manufacturers use the synthetic chemical polysorbate 80 as the base and main ingredient in the softgel capsule, whereas others use only natural citrus or coconut oil fractions to do the same job because we prefer to have natural bases.

Selective facts produce poor journalism (or science).

Selective facts produce poor journalism (or science). For example, the Women's Health Study had a 7% reduction in major cardiovascular events with vitamin E, a number that was not significant. But there was a significant 24% reduction in cardiovascular death in the vitamin E group. Would you characterize that as a failure for vitamin E? The media did. Yet, the authors of the study admitted that, "This was largely attributable to fewer sudden deaths in the vitamin E group (38 vs 51 among women assigned to placebo) and fewer deaths from other cardiovascular disease (ie, deaths due to cardiovascular diseases other than ischemic heart disease and cerebrovascular disease, 20 vs 34, respectively)." The Williams College ginkgo study in JAMA allowed participants to miss up to 6 daily doses over a 2-week period (nearly 50%!) before they were eliminated for non-compliance. It also tested only one brand of ginkgo (Ginkoba) on healthy volunteers for only six weeks, with results (by convention) not applicable to other brands. This was an obvious attempt to see whether a quick, drug-like effect could be obtained from a short course of supplementation. Longer term studies are more authoritative, especially if compliance is better. The CoQ10 statement is laughably wrong: "Coenzyme Q10 has not been carefully tested to see if it is safe and effective. Because coenzyme Q10 is sold as a dietary supplement rather than a drug, it is not regulated by the US Food and Drug Administration." This is a complaint that the FDA does not test individual dietary supplement products for potency or approve individual label claims. The agency does have the longstanding right to veto dietary supplement label claims and to remove any mislabeled or adulterated product from the national market. This contrasts with the FDA's explicit approval of drugs and drug claims, though the agency doesn't test individual pharmaceuticals for potency or safety, either. Of course, the FDA would take issue with their supposed inability to regulate dietary supplements. They even claim the opposite on their web page. Note the first 4 words: "FDA regulates dietary supplements under a different set of regulations than those covering "conventional" foods and drug products (prescription and Over-the-Counter). Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), the dietary supplement manufacturer is responsible for ensuring that a dietary supplement is safe before it is marketed. FDA is responsible for taking action against any unsafe dietary supplement product after it reaches the market. Generally, manufacturers do not need to register their products with FDA nor get FDA approval before producing or selling dietary supplements.* Manufacturers must make sure that product label information is truthful and not misleading. FDA's post-marketing responsibilities include monitoring safety, e.g. voluntary dietary supplement adverse event reporting, and product information, such as labeling, claims, package inserts, and accompanying literature. The Federal Trade Commission regulates dietary supplement advertising." regarding the CNN report: http://www.cnn.com/2007/HEALTH/04/09/chasing.supplements/index.html
