No to both questions. The FDA has removed or prevented the introduction of dietary supplements that were shown to pose hazards for the public. Dietary supplements have shown a tremendous safety record, as would be expected for health-promoting products. In fact, food is more of a hazard than dietary supplements could ever be. Also, established and reputable dietary brands, such as Schiff, have internal guidelines that prevent questionable or unsafe products from being considered. Warning and Caution statements appear on dietary supplement product labels if there are any contraindications known. Few, if any, Americans routinely eat a “good” diet, as shown repeatedly by U.S. Government surveys. Variable intake of essential nutrients may be good enough to prevent classical nutrient deficiency diseases, but practically every health condition has been linked to inadequate dietary intake of healthy foods. Dietary supplements contain healthy substances derived from foods, and should be thought of as part of a healthy diet. Furthermore, there is now considerable scientific evidence that optimal intake of some nutrients, like vitamin E, is impossible even from a healthy diet. In other words, more is better for some nutrients. Since over half of all Americans take some type of dietary supplements, it is obvious that most Americans believe they need to improve their diets, and dietary supplements are a good way.
