IT HAS OFTEN BEEN FALSELY REPORTED THAT VITAMIN C CAUSES KIDNEY STONES
Truth and Lies About Vitamin C, Kava Kava, St. John’s Wort, Beta Carotene, and more…
(Editor’s note: This month we bring you the first segment of Dr. Rona’s feature on Nutrition Myths, which covers the first two items on his Top Ten list. To see the complete Top Ten, click on the link at end of article.)
This list of nutritional medicine myths hasn’t changed much in nearly 40 years. I hear about one or more of them every day in my private practice. The people making the erroneous assertions tend to be very dogmatic in their views. The source of these misleading facts is most often practising medical doctors untrained in nutritional medicine, or those who are just plain out of date. These are the most widely known fake news items in natural medicine that diehard. Although there are others not listed here, what follows is my current top ten.
Vitamin C Myths
- causes DNA damage (leading to cancer)
- protects cancer cells from being destroyed by chemotherapy
- causes or exacerbates gastric ulcers and diabetes
- causes thrombosis (abnormal internal blood clotting)
- causes rashes, nausea or other gastric upset, abdominal cramps, headaches, and fatigue
- interferes with the metabolism of other nutrients (e.g. sodium and iron) causing either overload or depletion
- is only a vitamin (micronutrient); typical daily diets supply “enough” ascorbate
NUTRITION MYTH #2: Herbs, Vitamins, and Minerals Can Be Toxic
First of all, whole herbs are plants and NOT drugs. If you extract one ingredient from any herb and concentrate it and patent it, then yes it becomes a drug. Drug companies are famous for using herbs as a source for new drugs. For example, some companies have extracted THC from marijuana, then concentrated it and patented it as a drug. The fact that this extract doesn’t work as well as the whole plant is of no concern to drug companies. Adverse drug reactions are the fourth leading cause of death in North America. None of these fatal reactions involve commonly used herbs or other supplements. Conventional medical doctors and their prescription drugs kill more patients in one day than any natural therapy ever did.
This is not to say that herbs are free of side effects, just that there is no evidence that they come anywhere close to the danger posed by prescription and over-the-counter drugs. Poison control center statistics from the U.S. have shown a total of zero deaths in the past 30 years from any vitamin, mineral, herb, amino acid or nutritional supplement. The myth of nutritional supplement toxicity is therefore unwarranted, yet continues to die hard. Some herbal remedies like St. John’s Wort can interact with numerous drugs but, once again, reports of toxicity are nonexistent and exaggerated by big pharma and medical sources. As many have now stated, “Where are the dead bodies?”
A few years ago, there was much concern about the mildly relaxing herb known as kava kava. In fact, it was taken off the market in Canada due to concerns about liver toxicity. These reports were later shown to be unproven so kava was put back on the market and you can get it now from any health food store.
At one time, beta carotene supplements were accused of causing lung cancer. The study that made this ridiculous argument was later debunked because cigarette smokers were used as study subjects in order to make this erroneous conclusion. There have also been false reports of the absurd belief that folic acid can increase cancer risk. All these myths are completely without evidence.
I frequently recommend 10,000 IU of vitamin D to adults who have low blood levels, fail to get enough sun exposure, use sunscreen on a daily basis due to cancer fears, and who have been advised by doctors to stay out of the sun. Often, these patients will go back to their family doctors who quickly scare them about vitamin D causing liver toxicity, kidney stones, and other horrible side effects at doses over 1,000 IU daily. The patients then return to my office and we re-check the blood levels of vitamin D and, of course, they are still too low, below the acceptable reference range.
There is zero evidence that vitamin D or any fat-soluble vitamin is toxic at the 10,000 IU therapeutic dose. If one is on blood thinning medication and a long list of drugs, there are indeed drug-nutrient interactions, mostly evidenced by a depletion of nutrients by the drugs and not the other way around. For example, statin drugs used to lower cholesterol will deplete vitamin D and coenzyme Q10. For more information on this see my article in the March 2017 issue of Vitality (https://tinyurl.com/l4ykpjl).
Yet another piece of false news is that vitamin E causes high blood pressure. When subjected to scientific scrutiny, this turns out to be completely false. In fact, one study (Archives of Neurology 2000; 57:1503-1509) concluded that the reverse was true: taking vitamin E if you have high blood pressure reduces the risk of stroke. And if your blood pressure is normal, vitamin E has no effect on it or your risk of developing a stroke.
