I have been taking inventory of my bottles of vitamins, and wondering, do I really need all of them? I logged on to the Office of Dietary Supplements (yes there is one) and started some research. Here is some information I found:
First of all, the definition of a dietary supplement, (what I call vitamins) is that they are any products that people add to their diets in the form of vitamins, minerals, herbs, and amino acids. By law, companies that make these products cannot claim they prevent, treat, or cure disease. For example, a product cannot claim that it can “cure cancer” or “help you lose weight”.
You shouldn’t take dietary supplements instead of eating healthy foods. If you are having surgery, taking other supplements or medicines, or have health problems, dietary supplements may be harmful. You should check with your doctor before using a supplement especially if you are pregnant or nursing a baby, taking other medicines or supplements, have diabetes, high blood pressure, or any other health problems. Dietary supplements are regulated similarly to food regulations. This means the FDA does not approve dietary supplements before they are sold. The FDA can only take action against products that are not safe or products that make false claims after they are for sale.
Tips for searching the web for information on supplements – Ask yourself these questions:
Who runs the website? What is the website trying to do? Is it telling you about the product or just trying to sell it? Where does the website get its information? Are there studies that back it up? Is the information up to date? Check the dates to see when it was posted or updated.
For me, I am whittling down my vitamin intake to vitamin C, vitamin D3, and a multi-vitamin/mineral a day.
