Green tea remains popular for its antioxidant content, particularly epigallocatechin gallate, or EGCG. Researchers have studied this catechin for its potential anti-inflammatory effects.
However, experts say several other drinks also provide significant antioxidant compounds. These include coffee, berry juice, hibiscus tea, pomegranate juice and hot cocoa.

Antioxidants help the body neutralise free radicals. Excess free-radical activity can cause oxidative stress, which may damage cells and contribute to chronic disease.
However, antioxidant content varies by ingredients, preparation, processing and serving size. A higher laboratory antioxidant score also does not guarantee better health outcomes.
1. Coffee
Coffee contains chlorogenic acids and other polyphenols with antioxidant properties. Its widespread consumption can make it a major source of antioxidants in many diets.
“Coffee is a very underappreciated source of antioxidants, primarily in the form of chlorogenic acids (CGA) and other polyphenols,” registered dietitian Karen E. Todd said.
“However, because coffee is a commonly consumed beverage and a regular part of many people’s diets, it can actually be a large contributor to the intake of antioxidants in the average person’s diet.”
Studies have explored chlorogenic acids for their possible role in reducing markers associated with oxidative stress. Added sugar and high-fat creamers, however, can change coffee’s overall nutritional value.
2. Berry Juice
Berries contain anthocyanins, which produce their deep red, purple and blue colours. Researchers have studied these antioxidants for potential cardiovascular and metabolic benefits.
Todd recommends minimally processed berry juices with little or no added sugar. Acai, maqui and wild blueberry juices can offer concentrated amounts of antioxidant compounds.
Whole berries remain a valuable option because they also provide dietary fibre. Many commercial fruit drinks contain added sugar and limited real juice.
3. Hibiscus Tea
Hibiscus tea contains polyphenols and develops a deep red colour after brewing. People can drink it hot or cold.
Research has examined hibiscus for potential effects on blood pressure and LDL cholesterol oxidation. However, it should not replace prescribed treatment for high blood pressure or cholesterol.

Consumers taking medicines should consult a qualified healthcare professional before making hibiscus tea a regular part of their routine.
4. Pomegranate Juice
Pomegranate juice contains anthocyanins, ellagitannins and other polyphenols. These compounds help neutralise free radicals linked to oxidative stress and cellular damage.
Research has explored pomegranate’s possible effects on cardiovascular and metabolic health. Consumers should choose 100% pomegranate juice without added sugar when possible.
Portion control also matters because fruit juice can contain substantial natural sugar.
5. Hot Cocoa
Cocoa provides flavanols, a group of plant compounds that researchers have studied for potential cardiovascular benefits.
“Cocoa contains a large amount of flavanols. So, dark chocolate can be part of an antioxidant-rich diet,” Todd said.
Unsweetened cocoa powder or dark cocoa products generally provide a better option than heavily sweetened mixes. Consumers can control the added sugar when preparing hot cocoa at home.
Experts still recommend getting antioxidants from a varied diet rather than relying on one drink. Citrus fruits, carrots, spinach, kale, watercress and parsley also provide beneficial compounds.
Buckwheat, amaranth, millet and quinoa can further expand antioxidant intake. A colourful diet containing vegetables, fruits, legumes, whole grains, nuts and seeds offers a wider range of plant compounds.
