HPRC Fitness Arena: Dietary Supplements
Vitamin B12 is one of the eight B vitamins and is water-soluble. Our bodies do not store vitamin B12 so we must consume it daily. It is an important nutrient that helps make DNA, the genetic material in cells, and is essential for normal functioning of the brain and nervous system. Good food choices for vitamin B12 are beef liver, clams, fish, meat, poultry, eggs, and other dairy products. Read the Office of Dietary Supplement’s Vitamin B12 Fact Sheet for additional information.
We know about colas, coffee, tea, and chocolate, but caffeine can also be found in some over-the-counter drugs and herbal dietary supplement products. Energy drinks contain caffeine, and some also contain guarana, a plant with high amounts of caffeine. Yerba mate, green tea extract, and kola nuts are also sources of caffeine, and can be found in weight-loss and performance-enhancing dietary supplements. Be sure to read labels for hidden sources of caffeine.
The marketing and selling of dietary supplement products has become a 20-billion-plus industry. Consumers are bombarded with ads, and some people turn to them as “healthier” choices to prescription and over-the-counter medications. Consumers should seek products that have been properly manufactured and should be aware of potential interactions with medications.

Tainted dietary supplements most often occur among products typically marketed for weight loss, sexual enhancement, and bodybuilding. They can have deceptive labeling as well as undeclared, harmful ingredients. The question is: How can consumers protect themselves from these products?
The Food and Drug Administration (FDA) has recently taken some steps to help consumers look out for potentially harmful dietary supplement products. Consumers and healthcare professionals can receive notifications from the FDA by subscribing to the RSS feed. The Commissioner of Food and Drugs also sent a letter to the dietary supplement industry reminding them of their responsibility to prevent the sale of tainted products in the United States. The FDA has also made it easier to report to the FDA about tainted products.
Some of these tainted dietary supplement products contain active ingredients of FDA-approved drugs or other compounds that are not classified as dietary ingredients. These products can have serious side effects, including death. The FDA has identified roughly 300 tainted products that are not legal dietary supplements and are warning consumers about the serious side effects of these products. Consumers should be cautious of:
- Product ads that claim to “melt your fat away,” or claim that “diet and exercise [are] not required,” or products that use the words “guaranteed,” “scientific breakthrough,” or “totally safe.”
- Products that use numerous testimonials about “results seen” from using the product.
- Any product that is labeled or marketed in a foreign language. Consumers should not buy or consume these products.
- Products that are marketed as herbal alternatives to FDA-approved drugs.
- Products marketed and sold on the Internet.
There have been some recent voluntary recalls due to FDA investigations of dietary supplement products. Some of these have included weight-loss products that contained the prescription drug ingredient sibutramine. Sexual enhancement products have also been recalled for containing the undeclared drug ingredients sulfosildenafil and tadalafil. Other products marketed as supplements have been identified as containing various prescription drug ingredients.
It is important that consumers be aware that, under the Dietary Supplement Health and Education Act of 1994, companies do not need FDA approval prior to marketing such products. Thus, generally speaking, the FDA does not approve dietary supplements.
Consumers need to be savvy when they make product purchases, and when in doubt, check with a healthcare professional or registered dietitian to determine if you need a dietary supplement product and to help determine what could be a tainted product. If it looks too good to be true, chances are it is. For more information, read the “FDA’s Beware of Fraudulent ‘Dietary Supplements’.”
CNN.com is reporting on a new government study which reports more than half of American adults take at least one dietary supplement. But despite their popularity, many experts remain skeptical of their effects.The study, sponsored by the Centers for Disease Control and Prevention's National Center for Health Statistics, found that more than 40 percent of Americans used supplements from 1988 to 1994, but by 2006 more than half were doing so. Multivitamins were found to be the most commonly used supplement.

Red 40, Yellow 5, Yellow 6, and other dyes are artificial colorings allowed in foods in the U.S., yet there is a long-standing debate over whether food dyes contribute to hyperactivity in children. The Food and Drug Administration’s (FDA) Food Advisory Committee met the last week of March and determined that there is not enough evidence to support the link between food dyes and hyperactivity in children. For now, there will be no warning labels on food products containing dyes.
