Dietary supplements can help you consume the right amount of different nutrients. They’re usually available in pill form, and you can buy them over the counter (OTC). You can get supplements that contain many common vitamins, like vitamin A or D, and minerals, like magnesium. You can even get multivitamins that contain various nutrients.

Many people can get adequate amounts of these nutrients from natural sources in their diets. But sometimes, this still isn’t enough to get the recommended amounts, which is where dietary supplements come in.

But with so many brands and types of supplements available, it can be difficult to decide which is best for you. There are different strategies that can help you choose high quality vitamins and supplements.

How are supplements regulated?

The Food and Drug Administration (FDA) regulates foods and medications, making sure they’re safe and effective for the general public. However, the FDA does not have the authority to approve dietary supplements in the same way.

That said, dietary supplements must still adhere to certain laws and regulations. For example, supplement manufacturers need to ensure that their products reach certain safety standards, such as ensuring they don’t contain any dangerous ingredients or impurities.

They must also display a label that lists all the ingredients in the supplement, as well as the serving size and the number of servings. Manufacturers must ensure that the labels are truthful about the contents of the supplements.

The FDA can also still play a role in ensuring the safety of dietary supplements in different ways, including:

  • inspecting the manufacturing facilities
  • monitoring reports of adverse events caused by supplements
  • periodically reviewing the labeling information of different supplements

The FDA can then take action against any misleading or unsafe supplement manufacturers.

Supplement manufacturers can also submit to third-party testing, although this isn’t a requirement by law. Third-party companies can test the substances and ensure the supplements:

  • contain what’s stated on the label and in the amounts listed
  • are standardized from batch to batch
  • do not contain contaminants or undeclared ingredients

How to choose safe supplements

While the law requires dietary supplements to meet safety standards, this doesn’t mean unsafe or illegal ones aren’t available on the market. However, there are ways you can make informed choices about your supplements:

  • Check the labels: Make sure the labels are clear and tell you exactly what’s in the supplement.
  • Use trusted brands: You may be more familiar with certain brands. More well-known brands are more likely to be safe to use. You can also research the manufacturer to ensure that they’re trustworthy.
  • Ask a healthcare professional for advice: Always speak with a healthcare professional before adding new supplements to your routine. They may be able to guide you on which brands are certified and safe.
  • Look for certificates from third parties: The best way to ensure the safety of a supplement is to find one that has been certified by a third party. If this is the case, the product might state that it has a certificate of analysis (COA).
  • Consider the claims carefully: If a supplement makes bold or unrealistic health claims, such as being a “miracle cure,” that seem too good to be true, they probably are. Aim for supplements backed by research and avoid anything claiming to be a quick fix.
  • Research product recalls and warnings: If the FDA finds something wrong with a supplement, they can get it recalled, meaning it won’t be available to purchase. If you know which products have been recalled, you can ensure you’re only taking safe supplements.

Are supplements effective?

Many vitamins and supplements have undergone extensive research to ensure their safety and effectiveness, but this depends on what they contain. Supplements may include:

  • vitamins
  • minerals
  • herbs
  • enzymes
  • amino acids
  • other ingredients

According to the National Institutes of Health (NIH), dietary supplements are generally considered safe and effective in helping you get the required amounts of various nutrients. However, not everyone needs to take supplements.

A balanced diet is usually enough to provide most people with enough nutrients. Doctors often advise varying your diet before introducing supplements into your routine. If you have a deficiency, they might recommend supplements.

Summary

Many different vitamins and supplements are available on the market. It’s important to choose high quality ones to ensure their safety and effectiveness.

The FDA doesn’t approve supplements before they reach the market, which means it’s easier for low quality ones to be available. But they still need to follow strict guidelines and regulations to ensure they’re safe for consumption. Stick to trusted brands with clear labeling and supplements displaying a COA.
