Overview of Dietary Supplements

According to the National Institute of Health and as defined by the Congress of the United States, a dietary supplement is a product that is intended to supplement the diet; contains one or more dietary ingredients (including vitamins; minerals; herbs or other botanicals; amino acids; and other substances) or their constituents; is intended to be taken by mouth as a pill, capsule, tablet, or liquid; and is labeled on the front panel as being a dietary supplement

In today's fast-paced world, many people do not have time to sit down and properly eat a meal or plan-out a balanced healthy diet. Poor food choices, lack of exercise and a general sedentary lifestyle in front of the computer or TV have negatively affected the health of millions of people.  Supplements can help these people improve their health by providing much-needed nutrients and vitamins.

Labeling of Dietary Supplements


If we use this definition, a lot of dietary supplements in today's market should be disqualified. But they are not. Unfortunately, many products that saturate the shelves, claim to do more than just supplement the diet. They claim to diagnose, cure, mitigate, treat, or prevent a disease. Such claims may not legally be made for dietary supplements. 

The Food and Drug Administration (FDA), the United States governmental body that is responsible for protecting and advancing the public health regulates label claims. The label of a dietary supplement may contain one of three types of claims: a health claim, nutrient content claim, or structure/function claim.

Since 1994, the FDA also reviews products for their safety before they are marketed for human consumption. However, unlike drug and food products, and contrary to popular belief, the FDA does not need to approve dietary supplements for safety or effectiveness prior to them reaching the marketplace. Rather, like Napoleonic Code, once a dietary supplement is marketed, the FDA has to do the extraordinary task to prove that the product is indeed not safe in order to limit its use or remove it altogether from the market.

The label of a dietary supplement must be truthful and clear. If the label does not meet this criteria, the FDA is able to remove the product from the marketplace or sanction the manufacturer. There are three general items that the FDA requires that appear on the dietary supplement label:

General Information

  • Name of the product
  • Net quantity of contents
  • Name and place of business of manufacturer, packer, or distributor
  • Directions for use

Supplement Facts Panel

  • Serving size
  • List of dietary ingredients
  • Amount per serving size
  • Percent of Daily Value
  • Total weight of the blend
  • Components of the blend in order of predominance by weight

Other Ingredients

  • Fillers
  • Artificial colors
  • Sweeteners
  • Flavors
  • Binders

Quality Control and Standardization

Quality control is of utmost importance. It is difficult to determine the quality of a dietary supplement or its formula simply by reading its label. That is why certain measures need to be in place in order to assure consumers of the product's safety and put their minds at ease.


The degree of quality control depends on the manufacturer, the supplier, and others in the production process chain. Furthermore, dietary supplements are not required by federal law to be tested for safety or effectiveness before they are marketed or sold. Therefore, there is no set standard, just recommendations and guidelines that may or may not be followed. For example, the Good Manufacturing Practices (GMPs) issued by the FDA. The GMPs help guarantee the identity, purity, strength, and composition of dietary supplements by regulating the amount of and types of ingredients included in the formula, the possibility of contamination, and the improper packaging and labeling of a product.

So, how can you as the consumer know which products are legitimate, safe and composed of quality standardized ingredients? There are a few quality control measures that manufacturers can implement to all but ensure that the end product that the consumers receives is of premium quality and passes industry standards for safety.

  • Third Party Monitoring and Testing
  • Risk-Free Money Back Guarantee

Third party monitoring and testing performed by independent monitoring companies is a great way to guarantee that QA is in place. These organizations evaluate each company by first tracking its reputation and customer satisfaction. Then by verifying the quality of the company's products by checking its standardization process. This can be an expensive step for manufacturers, since if any contaminants or irregularities are found, then all of that batch of products must be disqualified and disposed of. That is why, many companies skip this step, hoping to skid by. In this case, the consumer is in jeopardy and at risk for poisoning or other adverse effects. Although dietary supplements are not required to be standardized in the United States, we think it is a good idea to buy from a company that implements this important step. An additional popular measure that goes a long way to show the vested interest of a manufacturer and how confident it is with its production is, whether or not, it offers a risk free money back guarantee. This type of promise is a good indication that the manufacturer stands by its products and its quality. If a supplement you are buying from does not offer this, take this as a warning sign and select another company. Choosing wisely can safeguard your health. Companies can also evaluate dietary supplements for their potential health benefits and risks by reviewing existing clinical trials, investigating consumers' feedback, conducting in-house laboratory studies or observational studies. All of these approaches serve as good indicators for patterns of use and the extent of their effects upon health.
