Dietary and Natural Supplements
FDA regulates dietary supplements processing, manufacture, labeling, and packaging under the Dietary Supplement Health and Education Act (DSHEA), which was passed in 1994 as an amendment to federal food regulations.9 Companies who manufacture dietary supplements are obligated to provide proof of safety of their products, and they are required to make sure label claims are truthful and non-misleading. For supplements that do not have a novel dietary ingredient, which is a dietary ingredient not sold to the government prior to October 15, 1994, manufacturers are not required to submit proof to FDA about a products safety, before or after marketing. FDA has pursued enforcement actions against dietary supplement products for safety problems, manufacturing violations, and improper marketing or misbranding, including the use of prohibited disease claims. While structure/function claims, which describe the effect of a substance on bodily structure or function (e.g., helps improve memory), are allowed, disease claims or claims that a product can diagnose, cure, mitigate, treat, or prevent disease (e.g., reduces pain and stiffness associated with arthritis) are prohibited on dietary supplement labels and require FDA approval and evidence to be used on the labels of approved drug products. DSHEA is intended to strike the right balance between providing consumers access to safe dietary supplements they can choose to help maintain and improve their health and giving the FDA the regulatory authority to take action against supplements and supplement ingredients that prevent safety problems or if they make false or misleading claims or are otherwise adulatory or misbranded.
I think The Food and Drug Administration is trying to, in our provisions, for qualifying health claims, whether for traditional foods or for dietary supplements, that there is no issue with the claims, as long as there is substantial scientific agreement; otherwise, there might be claims that might be made, depending on the extent of scientific evidence so far. In Australia, most dietary supplements are regulated in a complementary medicines category, including vitamins, minerals, herbs, aromatherapy, and homeopathic products, though some products can be considered foods of specialty purposes and regulated by food authorities. Many products are considered to constitute dietary supplements that are a significant component of patient care, including products for treating vitamin and mineral deficiencies, and supplements for use in pregnancy. Nutrients obtained through foods and supplements can have a variety of health effects.
For some individuals, supplements can be a helpful way to obtain nutrients that they might not otherwise have. Supplements are not for everyone, but older adults and others may need them to get nutrients they might otherwise be lacking. You probably do not need supplements if you are a healthy adult eating a variety of foods, including fruits, vegetables, whole grains, legumes, low-fat dairy products, lean meats, and fish. Whole foods, like whole grains, fruits, vegetables, and legumes, provide dietary fiber.
Supplements cannot duplicate all of the nutrients and benefits found in whole foods, such as fruits and vegetables. Whole foods are complex, providing all of the micronutrients that your body needs. So, too, do you reap the benefits of the other antioxidants and nutrients found in foods. If your vitamin C levels are low, and you are having difficulty getting enough from food that you eat, talk to your doctor about taking a supplement.
Taking nonsteroidal anti-inflammatory drugs may reduce your vitamin C levels If you regularly take these medications to treat your OA, you may need to take a vitamin C supplement. There is no evidence to suggest taking vitamin C supplements will help cure or prevent osteoarthritis (OA). Eating foods rich in vitamin C is important for your overall health, particularly if you are at risk of high blood pressure.
In some cases, excess vitamin and mineral intake can be harmful or produce undesirable side effects; thus, maximal levels are needed to assure safe supplementation with foods. Excess Intake – The population prevalence of excess intake is estimated as the proportion of the population whose nutritional intake exceeds a permissible upper limit. Reverting to Text This is particularly the case with vitamins and minerals identified as the nutrients of the shortfall, such as calcium and vitamin D. Although supplementation is highly prevalent, insufficient intake of micronutrients is still prevalent in high-income countries, where diet patterns are generally energy-rich, yet nutritionally inadequate. Metabolomics could be helpful to understand future supplement nutrient bioavailability. Continued efforts are needed to further clarify the potential differential roles of nutrients from foods as opposed to supplements for health promotion in general healthy populations and among individuals or groups with particular nutrient needs, including individuals living in low- and middle-income countries.
Supplements might have greater effectiveness at reducing noncommunicable disease risk in particular ethnic groups or individuals with lower food-based micronutrient intakes. With a recent rise in the percentage of individuals reporting following restricted eating patterns, such as the ketogenic, paleolithic, vegan, and vegetarian diets, supplementation is needed for assessment of supplementation for meeting the needs of these particular populations. Unlike many nutrients that are aggregated across a large number of foods and beverages, nutrients from supplements typically come from 1 or 2 products for an individual, most manufacturers offer similar labeled dosages across products (e.g., vitamin D is typically available in 400, 1000, or 2000 IUs, but not 1100 IUs), and individuals typically consume the same amount on the days they take them. These only apply to supplements containing vitamins and/or minerals, in which those products are regulated as foods, and address the supplement ingredients, including safety, purity, and bioavailability. Dietary supplements are included under the health functional foods (HFF) category in South Korea, regulated by the Ministry of Food and Drug Safety (MFDS) according to the HFF Act, in order to promote safety.
