Antioxidant supplements are available in many forms and contain varying amounts of nutrients considered to have antioxidant effects. However, much of the research on supplementation has been largely inconclusive.
When it comes to antioxidants, a food-first approach is your best bet at getting the most benefit. As a result, some supplement products may not contain the ingredients listed on the label.
When choosing a supplement , look for products independently tested or certified by organizations such as NSF , U. Pharmacopeia , or ConsumerLab. For personalized guidance, consult your healthcare provider, registered dietitian nutritionist RD or RDN , or pharmacist.
Antioxidants are substances in the body that protect us from free radicals. Free radicals may form from things like cigarette smoke, air pollution, sun exposure, and poor diet. They can damage cells in the body.
Over time, chronic high levels of free radicals can lead to oxidative stress , which can ultimately lead to chronic disease. Hundreds of substances have antioxidant properties, but they all work differently, and only a few are available through diet alone.
