Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Catechin, a type of polyphenol found in green tea and other plants, has been investigated for its antiviral properties, including potential effects against the common cold viruses (primarily rhinoviruses and coronaviruses). Laboratory studies (in vitro) have shown that catechins can inhibit the replication of certain viruses and may interfere with viral attachment or entry into host cells. Some clinical studies, particularly those examining green tea catechins, have suggested a modest reduction in the incidence or duration of upper respiratory tract infections, possibly due to both direct antiviral effects and immune-modulating properties.

However, the evidence remains limited and inconsistent. Most studies are small, not always well-controlled, and often involve catechin-rich extracts rather than isolated catechin. A few randomized controlled trials have reported that regular consumption of green tea catechins may reduce the risk of catching a cold, but effect sizes are generally small and not always statistically significant. As a result, while there is some scientific rationale and preliminary evidence suggesting catechins might help prevent or mitigate colds, the overall quality and strength of evidence are modest. Larger, well-designed clinical trials are needed to confirm any real benefit. Established treatment guidelines do not currently recommend catechin supplementation for cold prevention or treatment.
