My response to Bill O’Reilly’s program “Suzanne Somers' 'No Spin' on Vitamins”

,On Friday, February 19, 2010, Bill O’Reilly discussed recent legislation introduced by Arizona Senator John McCain (the Dietary Supplement Safety Act; S.3002) to impose new regulations on dietary supplements (vitamins, etc.) with Suzanne Somers. He made several points that are quite reasonable: that there should be warnings on labels, that we should know what is in the products, that manufacturers should be registered with the FDA, that ingredients should be disclosed, and that the FDA should have recall authority. I heartily agree with these common sense statements but need to point out that these elements are already mandated by current federal regulations that simply may be inadequately enforced. As in other fields, a few shady operators ignore laws when profits can be made by cheating. The answer to the occasional scofflaw is strict enforcement of existing law; without enforcement, both current and new laws would be equally worthless. But Mr. McCain’s proposed new law will severely decimate law-abiding companies in a misguided effort to import an unpopular regulatory scheme from Canada that gives unelected government bureaucrats absolute power over already-regulated vitamin products. Canadians now cross the border to buy American vitamins because their own government arbitrarily delays entry of new products for years at a time, miserly approving only 42% of products that have been submitted with all the required safety and efficacy documentation. Current laws can accomplish Mr. O’Reilly’s goals, if they are enforced. Dietary supplement manufacturers are already registered with the government, are already required to submit label claims to the FDA, are already prohibited from making medical claims for dietary supplements, and are already required to identity-test and list all ingredients on product labels. Ingredients that have been on the market for many years are already pre-approved by the FDA and all new ingredients must be specially pre-approved before going to market. All mislabeled products are considered adulterated and subject to mandatory recall. A recent adverse event reporting law promptly lets the FDA know of virtually any problem requiring medical attention in order to trigger recalls and new label warnings, This does not sound like an unregulated industry, even if enforcement can be improved in some areas. What we don’t want is the FDA, an agency that is cozy with pharmaceutical interests, to have complete power over every new vitamin formula that is merely a variation of already-approved ingredients. That kind of permanent government takeover will strangle an important health industry that in a free market added jobs and exports during the recession. Vitamins help Americans meet basic nutritional needs in a cost-effective manner without government funding and may have actually decreased some Medicare spending, according to the conclusions of authoritative Lewin Group reports. Understand and enforce the current laws before proposing a virtual federal takeover of an industry that is law-abiding, has welcomed recent regulations that have empowered federal authority over it, and would suffer great harm from a huge increase in unnecessary government interference. Think about it: If you were driving on the highway at 55 miles per hour and occasionally some jerk speeds by at 90, would dropping the speed limit to 45 correct the problem? Of course not. It obviously makes more sense to station additional cops along that stretch of highway to enforce current traffic laws than to collectively punish all drivers. Why is enforcement of vitamin laws any different? Target the outlaws, not the innocent! Neil E. Levin, CCN, DANLA www.honestnutrition.com

Unbalanced Fox news report misleads about vitamin-mineral safety

Unbalanced Fox news report misleads about vitamin-mineral safety By Neil E. Levin, CCN, DANLA I watched the special health report on vitamins and minerals on FOX-32 (How Do Vitamins and Minerals Really Affect Your Body? on 2/12/08, see link below), but was disappointed that the report exaggerated the risks of vitamins and minerals and minimized their benefits without any mention of the common deficiencies that exist in the American population. For example, the report cautioned about vitamin E causing blood thinning, but the Food and Nutrition Board of the Institute of Medicine has set an upper tolerable intake level (UL) for vitamin E (alpha-tocopherol) at 1,500 IU per day, which “is the highest dose unlikely to result in bleeding problems;” though the Institute has also said that the danger of the vitamin inhibiting clotting was not convincing. In other words, taking about four times the most common strength of even a hi-potency vitamin E capsule might be a problem in terms of affecting clotting, but this potency is higher than is available as a dietary supplement and one that people are unlikely to try without specific medical advice. Yet, somehow, the far more common danger of a vitamin E deficiency was completely ignored. This, despite the fact that, according to dietary data from the National Health and Nutrition Examination Surveys, ninety percent or more of the adults studied had usual intakes below the current Estimated Average Requirement. Why is a theoretical overdose problem even mentioned in the report, especially with no balancing mention of known deficiencies and benefits? What happened to fair and balanced reporting? And what are the benefits of vitamin E supplementation? An NIH-supported USDA -Tufts University study published in the medical journal JAMA reported, “…we observed a protective effect of vitamin E supplementation on upper respiratory tract infections, particularly the common cold,” for nursing home patients taking 200 IU of vitamin E daily. And Annals of the New York Academy of Sciences reported that, “The results of this clinical trial show that vitamin E supplementation significantly reduces the incidence rate of common colds and the number of subjects who acquire a cold among elderly nursing home residents.” Zinc was also mentioned in the FOX report as a possible overdose candidate, but levels required to reach the negative side effects mentioned are between 150-450 mg per day, again requiring a consumer to take several capsules to achieve this. The highest potency I have ever seen (in 35 years) was 75 mg, though 15-50 mg products are relatively common. Yet the median intake among American adults is just over 2/3 of the Daily Value, making deficiencies far more common than overdoses. Again, the FOX report ignored the common, greater danger in favor of sensationalizing a remote possibility of overdosing. Zinc is essential for many biochemical reactions in the body, and is most notably associated with immune function and wound healing. Yet isn’t FOX essentially warning people against taking zinc, hinting that they may be in danger but without any hint of the true risks and benefits? A dietician in the report stated that there is no proof that taking extra vitamin C shortens or prevents colds. That should come as news to the researchers at the University of Pittsburgh Medical Center. Publishing results of a Review Study in the medical journal American Family Physician in February 2007, these physicians reported that, “Thirty trials involving 9,676 cold episodes showed a statistically significant decrease in illness duration with vitamin C taken before onset of symptoms…. Likewise, 15 trials involving 7,045 cold episodes demonstrated a decrease in severity scores and in days confined to the home.” While there is some little evidence (not none) that vitamin C can prevent the incidence of colds, there is significant evidence that it can shorten the duration and severity of colds. Don’t you think that the FOX report is irresponsible by highlighting rare nutrient overdoses while ignoring common deficiencies? Also, why would one person’s opinion that vitamin C is worthless against colds trump the collective evidence of 30 clinical studies that met the strict criteria of a review study? Given these gross errors, I suggest that FOX assigns fact-checkers to review all medical and health reports. Let’s put an end to the flawed practice of naively taking the word of health professionals who appear not be up-to-date on what’s published in the medical literature. This is most important when demonstrably false blanket statements are made that inappropriately dismiss the safety and efficacy of essential nutrients that are known to be deficient in most Americans’ diets.
