Whether you’re a regular tea drinker or enjoy a cup of tea to relieve a sore throat, chances are you’ve had tea recently.
From tea’s anti-inflammatory properties to its role in promoting digestion, gut health, and cardiometabolic health, tea has a wealth of healthy properties thanks to the antioxidants in the brew. Antioxidants are compounds that help reduce oxidation and inflammation in the body by eliminating free radicals that can build up over time and promote disease.

Tea itself contains antioxidants. But there’s something you can add to get these compounds in your cup—and it may even boost their health benefits. We spoke to leading nutrition experts to learn more about this ingredient (it’s so easy to find) and why adding it to your tea is the best solution.
The most important ingredient for your tea to preserve the antioxidants
It’s lemon juice! Adding the citrus superstar can help preserve the tea’s antioxidants. A recent study looked at the effects of lemon juice on mate tea (a type of tea commonly known as yerba maté). Researchers found that adding lemon juice and chilling the tea boosted its antioxidant effects. Tea drinkers also said they liked the tea prepared this way better than drinking it plain. Previous research has found that adding ascorbic acid (also known as vitamin C, one of the two acids in lemon juice) to green and black tea also helped boost the brew’s antioxidants.
People have been squeezing lemon into their tea for a long time, so what makes this such a smart choice? Adding lemon to your tea can help antioxidants like catechins become more stable and better absorbed by the body, says Patricia Bannan, MS, RDN, author of From burnout to balance and founder of Wellness Intelligence. “Essentially, lemon acts as a natural preservative for the tea’s antioxidants,” she explains.
This is helpful during the digestive process. “Catechins are relatively unstable in non-acidic environments like the small intestine,” says Dr. Taylor Wallace, a food scientist and professor at George Mason University. “Both vitamin C and citrus juices interact with catechins and prevent their breakdown. By adding lemon juice to your tea, you can dramatically preserve a large amount of these compounds while also adding some extra vitamin C to your diet,” he says.
