Independent studies by private laboratories have shown that a large number of dietary supplement products do not contain the amounts of active ingredients that would be expected based on their labels. In addition, the FDA has found many products that are not accurately labeled contain ingredients that might be harmful or should not be found in such a product.
According to the FDA, recent examples include:
- Five of 18 soy and/or red clover-containing products were found to contain only 50% to 80% of the declared amount of isoflavones (the active ingredient claimed).
- One firm recalled dietary supplements because they contained excessive amounts of lead, which may pose a health risk especially to children and women of childbearing age.
- Another company recalled its folic acid dietary supplement, which is often taken by pregnant women to reduce the risk of birth defects, after it was discovered that the product contained only 35% of the amount of folic acid claimed on the label.

Olivol—The Heart of the Olive™
Olive extract provides highly bioavailable phenolic antioxidants.
Vitamin E—The Premier Antioxidant
Vitamin E is a family of essential fat-soluble nutrients (tocopherols) that act as powerful antioxidants. D-alpha tocopherol is the natural form shown to have the greatest nutritional and
biological value. Vitamin E plays a critical role in protecting LDL and cell membranes from oxidation, and works synergistically with other antioxidants to combat free radical damage. Emerging science has shown that other tocopherols also provide important biological activities and health benefits. These mixed tocopherols help leverage the health benefits of alpha tocopherol with other vitamin E compounds to provide a broad spectrum of antioxidant protection.
Carotenoids, provide a broad spectrum of antioxidant protection. Beta carotene (provitamin A) promotes healthy skin, a strong immune system, and helps maintain good vision.
A potent antioxidant, coenzyme Q10 (CoQ10) is essential for energy production in our cells. The body’s ability to synthesize or absorb CoQ10 declines with age, but taking USANA’s Mega Antioxidant can help you maintain healthy levels of this important nutrient.
Alpha Lipoic Acid
Alpha lipoic acid is a vitamin-like antioxidant that is both fat- and water-soluble. Easily absorbed
through the gut and transported across cell membranes, it offers protection against free radicals, both inside and outside the cell.
Bioflavonoids are a diverse group of naturally occurring plant compounds that exhibit a host of
biological activities, most notably powerful antioxidant properties that help complement, extend,
and synergize the activities of other antioxidants. In addition to synergistic activity from rutin, quercetin, hesperidin, green tea, and bilberry extracts, this diverse complex provides pomegranate and cinnamon extracts to provide broad-spectrum antioxidant support to further enhance and complement the effectiveness of antioxidants.
Complete Vitamin B Complex
Carefully proportioned B-complex vitamins, which are fundamental to energy production, metabolism, growth, and retention of normal homocysteine levels. The U.S. Centers for Disease Control has stated, "All women of childbearing age in the United States who are capable of becoming pregnant should consume at least 400 μg of folic acid per day for the purpose of reducing their risk of having a pregnancy affected with spina bifida or other neural tube defects.” Your daily dose of antioxidant should contain 1,000 μg of folic acid. Vitamin B12 is necessary for metabolism and the formation of red blood cells. It has been generally accepted that older adults are at greater risk of developing a vitamin B12 deficiency than younger adults. However, new research suggests that the prevalence of vitamin B12 deficiency in young adults may be greater than previously thought, and those who do not take a supplement containing vitamin B12 are twice as likely to be vitamin B12 deficient as supplement users, regardless of age group.

Minerals and trace elements represent less than one half of one per cent of the total nutrients we
consume every day. Yet without them, our bodies would be unable to efficiently use the carbohydrates, proteins, and fats in our diet. Many vitamins and enzymes need a mineral co-factor to function properly.
A component of hundreds of enzymes, zinc is involved in carbohydrate, fat, and protein metabolism. Zinc maintains healthy immune functions, helps in connective tissue formation, and helps maintain healthy skin.
Selenium is an essential component of the glutathione peroxidase antioxidant system, which helps combat the effects of free radicals.
Magnesium is essential for the formation and maintenance of healthy bones and teeth, which is where 70 per cent of the body’s magnesium is found. It is involved in the metabolism of carbohydrates and amino acids and plays an important role in neuromuscular contractions. It is also an activator of hundreds of enzymes that are essential for life.
Today’s poor diets and unhealthy lifestyles often put stress on the body’s blood glucose control
mechanisms. Chromium is an important component of the glucose tolerance factor (GTF), which helps retain healthy glucose metabolism, provided it is healthy to begin with. Healthy insulin and glucose levels are beneficial for weight management and sustained energy levels throughout the day.
Iodine is a crucial component in the production of thyroid hormones, which regulate metabolism, growth, reproduction, and the synthesis of protein. Supplemental iodine is especially important for people on a vegetarian diet, those who avoid seafood, or those who must restrict their salt intake.
Copper is a critical component of the enzyme superoxide dismutase (SOD), which is an important
antioxidant in cell cytoplasm, and acts as a catalyst in the formation of hemoglobin. Copper is also
essential for collagen synthesis.
Manganese is an important co-factor in the development and maintenance of bones. Manganese is an activator of numerous enzymes, and helps the body to metabolize carbohydrates, fats, and proteins.

A partial quote from subject article :
According to survey results from the 2009 "Life…supplemented" Healthcare Professionals Impact Study, 87 percent of nurse practitioners agreed that dietary supplements can play an important role in improving or maintaining the health of their patients. Additionally, 100 percent of nurse practitioners surveyed reported having a conversation about supplements with a patient, including 55 percent who indicated that they had initiated the conversation.
