Does Coffee Lower Blood Pressure More Than Tea?

You’ve heard tea lowers blood pressure—but what if your morning coffee does more? Many assume green or black tea is better for cardiovascular health, yet emerging research suggests coffee might have the edge, especially when it comes to measurable reductions in blood pressure.

Yes, according to German researchers cited in the Archives of Internal Medicine, coffee may help lower blood pressure more effectively than tea. While both drinks contain helpful polyphenols, coffee has one particular type that’s more active in reducing blood pressure—an effect not seen in either green or black tea.

What the Research Says About Coffee and Blood Pressure

German researchers reported that foods rich in cocoa powder—like dark chocolate—can help reduce blood pressure. However, their findings showed that neither green tea nor black tea demonstrated the same benefit. The key difference lies not just in caffeine, but in the specific polyphenolic compounds present in each beverage.

Why Coffee Might Outperform Tea for Blood Pressure

Both coffee and tea are loaded with polyphenols, the antioxidant compounds also found in fruits and vegetables that support heart health. But here’s the twist: coffee contains a particular polyphenol that is more effective at lowering blood pressure. This specific compound is absent in both green and black tea, which explains the differing impacts on blood pressure despite both drinks being sources of antioxidants.

Don’t Overdo It: The Caution on Drinking Too Much Coffee

While the research highlights coffee’s potential benefits for blood pressure, the German team also warned against overconsumption. Just because coffee may help lower blood pressure doesn’t mean drinking large amounts daily is wise. Excessive intake can lead to other health issues, so moderation remains essential.
