How do we know what is safe when choosing vitamins? I did a post about vitamins and mentioned that I take Flintstones. Maybe Flintstones are not the best choice for an adult but I like them, they taste good. I try and eat lots of fruits and green veggies but thought that a daily supplement with lots of vitamins and minerals can give me what I might miss.

I received a comment from someone that got me thinking about what else is in the bottle of Flintstones besides the vitamins and minerals. I did look at the back of the bottle and saw a lot of strange ingredients that I know nothing about. So, I'm not advocating taking Flintstones to anyone. Just to make that clear.

If you are thinking about taking dietary supplements such as vitamins, herbals or botanicals as alternative or complementary cancer treatments you need to consider your choice carefully. Few governmental standards are in place to control the production and ensure the safety, effectiveness, and quality of dietary supplements. So, it falls to you, the consumer, to gather truthful information about using these products safely.

The American Cancer Society website lists guidelines for choosing dietary supplement products:

• First, speak with your doctor or other health care provider about any supplement you might consider taking. He or she can probably tell you if the supplement has any risks to your health and if the supplement is safe to take with other medications you may be taking.

• Find information on the product written by recognized medical experts or government agencies. Bring this information to your doctor's attention. You can start on the Web by visiting the National Institutes of Health's Office of Dietary Supplements at http://dietary-supplements.info.nih.gov/ and clicking on Health Information."

• When you shop for supplements, look for the USP notation on the package label.

• If you are shopping for a botanical supplement, make sure to find a product that uses only the effective part of the plant. Avoid botanicals that have been made using the entire plant, unless the entire plant is recommended.

• Remember that a product described as "natural" is not necessarily safer or more effective.

• Consider the name and reputation of the manufacturer or distributor. Is it a nationally known name? Large companies with a reputation to uphold are more likely to manufacture their products under strict, quality-controlled conditions.

• Does the label provide a way to contact the company if you have questions or concerns about their product? Reputable manufacturers will provide contact information on the label or packaging of their products.

• Contact the manufacturer and ask about their quality control procedures and manufacturing processes.

• Try to avoid mixtures of many different supplements. The more ingredients, the greater the chances of harmful effects.

• Avoid supplements priced significantly lower than comparable products; they are likely to be of lower quality.

• Avoid products that claim to be "miracle cures," "breakthroughs," or "new discoveries," to have benefits but no side effects, or to be based on a "secret ingredient" or method. Such claims are almost always fraudulent, and the product may contain potentially harmful substances or contaminants.

• Avoid products that claim to be effective treatment for a wide variety of unrelated illnesses.

• Avoid products that claim to be safe or effective based solely on testimonials.
