Most people in the United States take one or more supplements either regularly or occasionally. Dietary supplements come in forms of vitamins, minerals, antioxidants, enzymes, herbal products, and many others. The preparation can be a tablets, capsules, soft gels, powders, and liquid. Because there are so many varieties out there, choosing the right kind of supplement may be challenging. Here are a few basic tips to consider before you decided to start consuming one.
Do some preliminary background check
Research the benefits and possible side effects of the particular compound you’re planning to take. Always consult a health care professional beforehand. Dietary supplements are products intended to supplement the diet. They are not drugs and, therefore, are not intended to diagnose, treat, cure, or prevent any diseases. Do not believe whatever claims the manufacturer made before doing some research of your own. Some supplements promise to help make us thinner, smarter, stronger or faster without making any other changes in lifestyle. If it sounds too good to be true, it probably is.
Consider the effectiveness of the supplement
Find out how much you need to consume in order to bring out the health benefits for your body without risking the side effects. Many popular products include ingredients in miniscule quantities, just so a much-publicized ingredient can be listed on the label, or vice versa, they include a very high amount of a particular ingredient while in reality our body only needs a minuscule amount. A good, but not perfect guide is to look up the recommended daily allowances (RDA) of that product. However, keep in mind that a product’s chemical formulation and how it is prepared affect how our body is able to take in the ingredients. This is called bioavailability. A high-dosed product, but low bioavailability is not very effective.

Be aware of safety and risk issues
The term ‘natural’ doesn't always mean safe. Many supplements contain active ingredients that can have strong effects in the body. Always be alert to the possibility of unexpected side effects, especially when taking a new product. Dietary supplements can also interact with certain prescription drugs in ways that might cause problems. Watch out for other catch phrases like ‘clinically tested/proven’ and ‘pharmaceutical strength’. Unlike drugs, which must be approved by the FDA before they can be marketed, dietary supplements do not require premarket review or approval by the FDA and the manufacturers do not have to provide any evidence about the claims they made before the product is marketed.
Look for quality assurance
Since the quality of nutritional supplements can vary widely, one strategy is to choose an established brand name, or one that's recommended by a health professional. Not every product uses high quality raw materials, or is manufactured according to accepted good manufacturing practices. Besides the FDA, several independent organizations like U.S. Pharmacopeia, ConsumerLab.com, and NSF International offer quality testing and allow products that pass these tests to display their seals of approval. These seals of approval provide assurance that the product was properly manufactured, contains the ingredients listed on the label, and does not contain harmful levels of contaminants.
