Dietary Supplement Regulation

Dietary supplements can be defined as products that are meant to augment your dietary nutritional needs, contains one or more ingredients like, vitamins, minerals, amino acids, and herbs. Dietary supplements are also intended to be taken orally and must be labeled as dietary supplements.

Once upon a time, the Food and Drug Administration (FDA) regulated dietary supplements the same way it regulated foods. However, all that changed in 2007 and their new manufacturing practice ruling makes sure that all supplements:

  • Are accurately labeled
  • Do not contain impurities or contaminants and
  • Are produced in a quality manner.

The FDA provides strict guidelines to manufacturers for the claims about the effects their products have on the body. So if a manufacturer makes a claim about his new product, they must notify the FDA so that the product can be reviewed.

The FDA regulations are there to ensure that dietary supplements are as safe and as efficient as the manufacturers claim.


Who Should Take Dietary Supplements?

Before you start any dietary supplement, remember that they were designed to supplement your diet and not as a replacement for nutritious foods. The complex nature of foods and all the benefits healthy eating patterns offer is something science has yet to be able to reciprocate. However, a lot of people require supplements because the required dose of minerals and vitamins they need can be hard to get in adequate amounts from your diet alone.

Dietary supplements are most beneficial to:

  • Nursing Mothers
  • Pregnant women
  • Senior citizens
  • Strict vegetarians
  • Those with chronic ailments like cancer, kidney, cardiovascular, or bone disease
  • People with food allergies or intolerances

Benefits of Dietary Supplements

If you’re not getting enough essential nutrients from your meals, supplements may help to bridge the gap in the number of nutrients required by your body. However, dietary supplements can never take the place of a healthy balanced diet.

Several studies have shown that nutritional supplements can be beneficial to your overall health and even helps in managing certain health conditions.  Calcium and Vitamin D for example, are vital in keeping your bones healthy as well as in reducing bone loss. Folic acid reduces the risk of certain congenital disabilities, and Omega-3 fatty acids may help some people with heart disease.
