Is Your Multivitamin Toxic?

Is Your Multivitamin Toxic?

In episode #11 (season 2) of CSI: Crime Scene Investigation, a woman poisons her husband with the chemical sodium selenite. Strange as it may sound, this exotic murder weapon, and it’s close cousin, sodium selenate, are listed as “nutrients” on the labels of most mass-markets vitamins. Even though both sodium selenite and selenate are classified as dangerous and toxic to the environment by regulatory bodies such as the Environmental Protection Agency (EPA) and the European Union, they are the primary forms of the mineral sold on the mass market today. In fact, most mass-market vitamins contain chemicals that the EPA does not allow in our public drinking water at levels above 50 parts per billion per liter. According to the EPA’s Maximum Contaminant Level (MCL) standards, the highest allowable level of selenium in public drinking water is 50 parts per billion (equivalent to 50 micrograms, dry weight). To get a sense of how small an allowable limit this is, 50 parts per billion is equivalent to a tablespoon of water in an Olympic-size swimming pool.

How can vitamin manufacturers advertise something as being a “nutrient” when the EPA—out of concern for our health—has barred it from our drinking water at all but exceedingly minute levels? Have sodium selenite/selenate really been shown to be toxic? A brief perusal of toxicology reports from the Hazardous Substances Databank (toxnet.nlm.nih.gov) and PUBMED (pubmed.gov) shows that both forms can be carcinogenic and genotoxic and may contribute to reproductive and developmental problems in animals and humans. The question is not whether these minerals have toxicity, but rather, at what level they overwhelm our capacity for their detoxification and/or biotransformation into non-toxic metabolites?

A word should be said here about the differences that exist between inorganic minerals and biologically active ones:

The selenium that is found in foods like brazil nuts, mustard seeds, and fresh produce grown in selenium-rich soil is infinitely different from the biologically inert forms being put in some multivitamins. In fact, i.e., sodium selenite/selenate can cause cancer, whereas the selenium found within food, or laboratory chelated forms like selenomethionine have all been shown to prevent and combat cancer.

The basic principle that explains this difference is that when you isolate a nutrient or vitamin out of the food complex within which it is naturally found, and where it is inseparably bound to thousands of known and unknown food factors (e.g., enzymes, protein chaperones, glyconutrients, etc.) it is no longer as beneficial to life. This is especially true in the case of vertebrate mammals who are equipped to get their minerals from the plants they ingest or through the biotransformation of inorganic minerals to organic ones by microflora in their gastrointestinal tracts.

The primary reason that sodium selenite/selenate are preferred by some vitamin manufacturers over safer, more beneficial forms like chelated or yeast-grown selenium is because it is more profitable to use raw materials of lower quality.

“You get what you pay for” is a saying that almost always rings true for dietary supplements. Buying industrial waste products, or chemicals that are considered hazardous waste, and repackaging them as “dietary supplements” can be extremely profitable.

Indeed, this is not the first time in American history that such a hoax has been perpetuated on the public. The FDA-approved use of fluoride in our drinking water and the use of radioactive cobalt-60 culled from nuclear reactors for the IRRADIATION OF conventional food illustrates how industrial waste products with known toxicity are eventually converted into commodities or technologies “beneficial to health.” Whereas initially these substances have very high disposal costs for the industries that excrete them into our environment, the liability is converted — through the right combination of lobbying, miseducation and “checkbook science” – - back into a commodity, with the environment and consumer suffering health and financial losses as a result.

Unfortunately, inorganic forms of selenum are not the only problem with mass-market vitamins. Take the multivitamin Centrum, for instance, whose manufacturer Wyeth is one of the most powerful pharmaceutical companies in the world. This vitamin contains the following chemicals:

Chemical: Amount Found in Centrum/ EPA Maximum Allowed Limit in 1 Liter of Drinking Water

1) Sodium selenite : 55 mcg/ 50 mcg

2) Nickelous sulfate: 5 mcg/ 100 mcg

3) Stannous chloride (tin): 10 mcg/ 4 mcg

4) Ferrous fumarate (iron): 18 mg/ .3 mg

5) Manganese sulfate: 2.3 mg/ .05 mg

6) Cupric sulfate: .5 mg/ 1.3 mg

In the left hand column above you will see the quantities of inorganic minerals found within each dose of Centrum. In the right hand column are the maximum quantity allowed by the EPA in one liter of drinking water In the case of stannous chloride (tin), ferrous fumarate (iron) and manganese sulfate there are significantly higher doses in Centrum than are considered safe for human consumption in a liter of water. Although the others listed are at levels well under the EPA’s allowable limit, it is simply amazing that they are found in a product for human consumption at any quantity given their known toxicity.

So, if these chemicals are toxic, how can they be marketed as beneficial to our health?

As of today no law forbids the use of these substances in dietary supplements, despite laboratory research demonstrating their toxicity in animals, and epidemiological and occupational data demonstrating their actual or potential toxicity in humans. This is due to the widespread acceptance in the U.S. of a a chemical and drug industry-friendly “weight of evidence” standard for toxicological risk assessment. Rather than using the “precautionary principle,” which dictates that a substance that is suspected of being harmful should be duly regulated in order to minimize the public’s exposure, the “weight of evidence” paradigm requires a panel of government appointed experts must evaluate all available toxicological data, and must come up with a consensus that the evidence, unequivocally, demonstrates the substance in question poses a serious health risk. Until such an assessment can be made, a number of substances with obvious toxicity are “innocent until proven guilty” and can be portrayed by irresponsible and/or uneducated manufacturers as being beneficial to human health. It is sad and ironic that at a time when smaller dietary supplement manufacturers are being accused of being “unregulated” and having poor quality standards (even when they are incurring great costs by using vastly superior ingredients) that massive pharmaceutical companies who have every resource at their disposal are allowed to market toxic chemicals to consumers under the banner of USP (United States Pharmacopeia) or “pharmaceutical grade” quality, and get away with it.

Ultimately, we need to use common sense in our purchasing decisions and realize that sometimes companies will intentionally mislead the public—with the complicity of regulatory bodies like the FDA—and will advertise a product that has no health benefits; or worse, may actually detract from our health. The fact that Centrum may or may not be “the #1 doctor multivitamin brand” is irrelevant, considering that one does not ordinarily go to a doctor to seek wise counsel on nutrition. It is simply not their specialty.

The irony is that billions of dollars in health care cost —and the suffering these costs represent—could be saved every year if Americans took the simple step of taking a good multivitamin every day. It is advisable to look for product manufacturers that use high quality ingredient, including those from whole foods, as they are easier for our bodies to absorb and to utilize and therefore contribute more significantly to filling the voids in our diet.
