Dietary SupplementsIn the United States, dietary supplements are substances you

eat or drink. It is also a product intended for ingestion that contains a "dietary ingredient" to add further nutritional value to (supplement) the diet. A "dietary ingredient" may be one, or any combination, of the following substances (U.S. Food and Drug Administration, 2015): a vitamin a mineral an herb or other botanical an amino acid a dietary substance for use by people to supplement the diet by

increasing the total dietary intake a concentrate, metabolite, constituent, or extract

These supplements can be found in many forms such as tablets, capsules, softgels, gelcaps, liquids, or powders. “Some dietary supplements can help ensure that you get an adequate dietary intake of essential nutrients; others may help you reduce your risk of disease” (U.S. Food and Drug Administration, 2015).

FOOD AND DRUG ADMINISTRATION (FDA)“The FDA regulates both finished dietary supplement products and dietary ingredients. Moreover, the

“FDA regulates dietary supplements under a different set of regulations than those covering "conventional" food and drug products. Under the Dietary Supplement Health and Education Act of 1994 (DSHEA)” (U.S. Food and Drug Administration, 2015).

FACTS: Manufacturers and distributors of dietary supplements and dietary ingredients are prohibited from

marketing products that are adulterated or misbranded.  In short, this means that these companies are responsible for evaluating the safety and labeling of their products before marketing to ensure that they meet all the requirements of DSHEA and FDA regulations (U.S. Food and Drug Administration, 2015).

The FDA is responsible for taking action against any adulterated or misbranded dietary supplement product after it reaches the market (U.S. Food and Drug Administration, 2015).

Although dietary supplement manufacturers must register their facilities with FDA, they are not required to get FDA approval before producing or selling dietary supplements. It is the responsibility of the Manufacturers and distributors to ensure all claims and information on the product label and in other labeling are truthful and not misleading (U.S. Food and Drug Administration, 2015).

Under FDA regulations at 21 CFR  part 111, all domestic and foreign companies that manufacture, package, label or hold dietary supplement, including those involved with testing, quality control, and dietary supplement distribution in the U.S., must comply with the Dietary Supplement Current Good Manufacturing Practices (CGMPs) for quality control (U.S. Food and Drug Administration, 2015).

The manufacturer, packer, or distributor whose name appears on the label of a dietary supplement marketed in the United States is required to submit to FDA all serious adverse event reports associated with use of the dietary supplement in the United States (U.S. Food and Drug Administration, 2015).

FDA regulates dietary supplement labels and other labeling, such as package inserts and accompanying literature. The Federal Trade Commission (FTC) regulates dietary supplement advertising (U.S. Food and Drug Administration, 2015).

WARNINGS AND SAFETY

Many supplements contain active ingredients that can have strong effects to your body. It is best to be alert to the possibility of unexpected side effects, especially when taking a new product (National Institute of Health, 2011). Supplements are most likely to cause side effects or harm you when you take them instead of prescribed medicines or when you take many supplements in combination (National Institute of Health, 2011). Above all, some supplements can increase the risk of bleeding or, if a person takes them before or after surgery, they can affect the person's response to anesthesia (National Institute of Health, 2011). To add, Dietary supplements can also interact with certain prescription drugs in ways that might cause problems, for example:

Vitamin K can reduce the ability of the blood thinner Coumadin to prevent blood from clotting (National Institute of Health, 2011).

St. John's Wort can speed the breakdown of many drugs (including antidepressants and birth control pills) and thereby reduce these drugs' effectiveness (National Institute of Health, 2011).

Antioxidant supplements, like vitamins C and E, might reduce the effectiveness of some types of cancer chemotherapy (National Institute of Health, 2011).

Always keep in mind that some ingredients found in dietary supplements are added to a growing number of foods, including breakfast cereals and beverages; therefore, taking more than you need is always more expensive and can also raise your risk of experiencing side effects (National Institute of Health, 2011). More importantly, be cautious about taking dietary supplements if you are pregnant or nursing.

IMPORTANT: If you suspect that you have had a serious reaction from a dietary supplement, let your health care provider know. He or she may report your experience to the FDA. You may also submit a report to the FDA by calling 800-FDA-1088. In addition, report your reaction to the dietary supplement company by using the contact information on the product label (National Institute of Health, 2011).

WARNINGS AND SAFETYDon’t fall for fad weight-loss claims, FTC warns

Dated January 10, 2014

The Federal Trade Commission this week cracked down on four marketers of those weight-loss products, announcing that they will have to refund consumers a total of $34 million. The products were (Consumer Reports, 2014). Sensa, a food additive ($26.5 million) LeanSpa, which promoted acai berry and “colon cleanse” weight-loss

supplements ($7.3 million) L’Occitane, which claimed that its skin cream would slim users’

bodies ($450,000)(Consumer Reports, 2014)

HCG Diet Direct, which marketed an allegedly unproven human hormone as a weight-loss treatment (financial penalty was suspended, since the company is unable to pay, the FTC says) (Consumer Reports, 2014) .

DIETARY SUPPLEMENTS PROS Disease Prevention

“Different types of dietary supplements can help prevent certain diseases and other medical conditions. For instance, folic acid taken during pregnancy can help to reduce the risks of the baby developing any birth defects. There are various other dietary supplements that help prevent the risks of simple to serious health conditions” (Health Research Funding, 2014).

Nutrient Deficiencies Correction“Nutrient deficiency can lead to severe medical problems

like bone fragility, anemia, nervous system abnormalities, and poor immune system. If you have developed nutrient deficiencies such as Vitamin B12 and iron deficiency, dietary supplements can help reverse the medical conditions effects to your general health as well as help to prevent them from developing” (Health Research Funding, 2014).

DIETARY SUPPLEMENT CONS Not A Food Replacement

Dietary supplements are not food replacements. They do not contain the complex constellation of vitamins and nutrients that foods contain, including phytochemicals. Phytochemicals are obtained from eating whole foods such as fruits, grains, and vegetables. Getting your essential body minerals and nutrients from foods is still better compared to relying on dietary supplements (Health Research Funding, 2014).

Potential ToxicityThe more the better is a rule that is untrue to dietary supplements. Fat-

soluble vitamins E, D, and A can accumulate to toxic levels within the body if taken in doses exceeding the recommended daily allowance (Health Research Funding, 2014). Also, botanicals and herbs can accumulate to toxic levels if you have underlying healthy conditions including liver disease and chronic kidney (Health Research Funding, 2014).

Side Effects Some dietary supplements can cause adverse side effects that may interact

with your prescription medication. Make sure that the dietary supplement you are taking is prescribed by your doctor, or made by a reputable health product manufacturer to ensure that you keep away from potentially dangerous side effects and interactions (Health Research Funding, 2014).

Dietary SupplementsThe Band Aid Approach

Some consumers mistakenly view supplements as a way to make-up for their poor diet!

Experts call this the Band Aid approach-where you think you can eat poorly and just take a vitamin and you’ll be equal to another person who eats well and exercises and takes care of their health and gets regular check-ups! (Health Research Funding, 2014).
