There are a few things to keep in mind when making an informed decision about which dietary supplement to choose. The National Institutes of Health acknowledge that you will likely make your decision based on price, quality and availability, but you can also get a recommendation from your doctor or registered dietitian.

First, a Word on Supplement Safety

This may come as a surprise, but the Food and Drug Administration does not approve supplements for safety or efficacy before they hit the market, although it does set something called Current Good Manufacturing Practices (CGMPs), which include requirements for preparation and storage.

The best you'll get for peace of mind is to look for products that have testing done by an independent group. Three groups that test for supplement quality are NSF, Consumer Lab and USP.

The USP verified mark is set by United States Pharmacopeia and ensures the supplement is tested to contain what is on the label in the stated potencies. This mark also checks for harmful contaminants and makes sure the supplement breaks down so it can be properly absorbed by the body.

Consumer Lab also checks for identity, strength, purity and if the supplement disintegrates appropriately in the body.

NSF is an independent public health testing laboratory that not only tests dietary supplements but also bottled water and home and commercial products.

If you see the words "standardized," "verified" or "certified" on a supplement label without a seal from one of these three groups don't get too excited — these words are not regulated and do not guarantee product quality or consistency, according to the National Institutes of Health.

For fish oil supplements, there is no official quality testing standard in the United States, so Nordic Naturals adheres to guidelines set by the European Pharmacopoeia Standard (EPS), Council for Responsible Nutrition (CRN) and the Global Organization for EPA and DHA Omega–3 (GOED) when manufacturing its fish oil.

Nordic Naturals uses wild-caught fish for its supplements, which have been used in more than 50 published research studies.

What to Remember When Choosing a Supplement Brand

  • Do your research before heading to the store.
  • Look for third-party testing.
  • Check for allergens on the label.
  • If necessary, get a recommendation from your doctor or a registered dietitian.

Do You Need a Supplement?

If you are a healthy adult, chances are you don't need a supplement. You can get all the vitamins and minerals you need daily by eating a balanced diet rich in whole foods: protein (plant or animal), fruits, vegetables, grains and dairy. Whole foods also give you healthy nutrients, such as antioxidants, that you can't get from a supplement, according to the Academy of Nutrition and Dietetics.

Some people may need to supplement their diet with a specific vitamin or mineral, and this is usually recommended by a physician or dietitian. For example, if you are recovering from surgery or illness, have problems absorbing nutrients or if you are on a calorie-restricted diet, you may need a supplement.

In addition, if you have increased nutrient needs such as pregnancy or are engaged in high-intensity sports, you may not be able to satisfy your nutrient needs with food alone. And those following a special diet, such as vegans, may need B12 supplementation because they don't eat animal or dairy products, according to September 2017 research published in the Journal of the International Society of Sports Nutrition.

Individual vitamin or mineral supplements should only be taken when you have consulted with your health care provider. Some vitamins are harmful if taken in excess, and some are simply not needed and will be excreted without being absorbed.

Warning

You should always consult with your doctor before taking a supplement to ensure it does not interact with any medications you may be taking.

Final Reminders on Supplement Safety

Dietary supplement companies are not permitted to market their products as a cure or treatment for any condition. If you see a statement like that on the label, it's wise to put the product back on the shelf.

In addition, the National Institute on Aging notes that you should avoid supplements with ingredients you don't need, and you should remember that just because a supplement has a higher dosage of a nutrient doesn't necessarily mean it's the better choice for you.
