How to Ensure High Quality Supplements

The best way to guarantee the quality of a product is to look for one that has been certified by an outside company. The law does not require third parties to perform tests, but vitamin and mineral supplements are subject to fairly limited regulation by the FDA. To ensure the safety and accuracy of a product, search for supplements that have been certified by a third-party testing organization. When it comes to supplements, if it sounds too good to be true, it probably is.

Credible supplements have peer-reviewed scientific literature that supports their use and effectiveness, as well as recommended dosages that are backed by science. All of the supplements that InsideTracker recommends are backed by numerous studies and come with personalized dosing instructions. Be aware of megadoses, as more doses don't always equal better results. Talk to your doctor if you are taking medications, are pregnant or breastfeeding.

Some accredited testing companies include USP, NSF International, Consumer Labs, and the Natural Products Association. Each one has a certification seal and you can search their websites for lists of verified products. People with nutrient deficiencies or those who are at greater risk of inadequate nutrient intake, such as pregnant women, may benefit from taking supplements as recommended by a medical professional. Your need for supplements is unique to you and cannot be fully determined with an article on the Internet or your favorite celebrity.

The FDA is responsible for overseeing manufacturing practices and the labeling process, but they do not approve the quality, safety, or effectiveness of supplements before selling them to consumers. If you can make a change to your diet, that's ideal, and then consider taking a supplement if needed.


, minerals, herbs, and other botanicals can have unintended negative consequences when combined with some medications, other supplements, foods, and alcohol (2). Many of these concepts about choosing high-quality supplements are discussed at length in a research review article co-authored by Dr.

The FDA requires that supplements have good manufacturing practices (CGMP) to ensure their safety, but they don't test or evaluate supplements before they go to market. Many people want to live a healthier lifestyle and try supplements, but it can be confusing and overwhelming to decide which ones to take, what brand to use, and if they're safe. From individual vitamins and minerals to nutrient blends and herbs, there are numerous supplement products on the market that claim to offer specific health benefits. If dietary or lifestyle changes aren't possible, consider adding that specific supplement.

However, there are certain conditions, medications, and circumstances in which supplements may be needed to meet nutritional needs. If you're like most people then you're taking supplements without advice from a health professional (doctor, specialized nurse, dietician etc.). Try to get the most nutrients from a varied and balanced diet and use supplements to bridge the gaps. This means that supplements aren't subject to the same strict processes as clinical trials to demonstrate their efficacy, purity or marketing claims before they enter the market.

However there are cases where supplements may be indicated such as nutrient deficiencies; conditions that cause malabsorption; inadequate access to food; and certain stages of life such as pregnancy.
