Coffee Lowers Blood Pressure More Than Tea, Study Shows

If you’re watching your blood pressure, you’ve likely heard about the benefits of tea—but recent research suggests coffee might be the better choice. With rising rates of hypertension linked to diets high in fatty foods, finding simple dietary adjustments is more important than ever. The question isn’t just whether coffee or tea is healthier overall, but which one actually does more to lower your blood pressure.

Yes, coffee can lower blood pressure as effectively as medication. In a study, coffee consumption matched the effects of antihypertensive drugs over two weeks, and may reduce heart attack risk by 10–20%. Coffee’s unique polyphenols appear more active in reducing blood pressure than those in tea.

Why Coffee Outperforms Tea in Lowering Blood Pressure

Both coffee and tea contain polyphenols—plant compounds known to support cardiovascular health. These are also found in many fruits and vegetables. But here’s the key difference: coffee contains a specific polyphenol that is more effective at lowering blood pressure, one that tea lacks entirely. This particular compound gives coffee an edge in cardiovascular benefits.

What the Research Found

According to findings published in the Archives of Internal Medicine (American Medical Association), foods rich in cocoa powder—including coffee—can help reduce blood pressure. Green and black teas, however, did not show the same effect. In a controlled trial, hypertensive patients were divided into two groups: one took prescribed hypertension medication, while the other consumed coffee-rich foods. After two weeks, both groups saw similar reductions in blood pressure. Researchers noted that replacing medication with coffee-based interventions could also potentially cut the risk of heart attacks by 10–20%.

The Role of Polyphenols in Cardiovascular Health

Polyphenols are bioactive compounds found in a wide range of plant-based foods. Both coffee and tea feature these compounds, which are generally associated with reduced risk of cardiovascular diseases. However, the specific type of polyphenol in coffee appears to be more potent in its blood-pressure-lowering effects. While tea contributes to overall health, it doesn’t offer the same targeted benefit for hypertension as coffee does.

Frequently Asked Questions

Does coffee really lower blood pressure as much as medication?

Yes, according to a study published in the AMA’s Archives of Internal Medicine, coffee consumption had effects on blood pressure comparable to antihypertensive drugs over a two-week period. While not a substitute for all patients, coffee showed significant promise in managing hypertension.

Is tea ineffective for lowering blood pressure?

Tea contains polyphenols that support general cardiovascular health, but research found it does not lower blood pressure as effectively as coffee. Green and black teas lacked the specific polyphenol that makes coffee more impactful for blood pressure control.

How much can coffee reduce heart attack risk?

Researchers estimated that using coffee-based dietary interventions in place of medication could reduce the risk of heart attacks by 10–20%. This benefit is linked to coffee’s measurable impact on blood pressure.

Can I drink too much coffee for my blood pressure?

Yes. While moderate coffee consumption may help lower blood pressure, excessive intake can lead to negative health effects. It’s best to consume coffee in moderation to balance benefits and risks.

What makes coffee’s polyphenols different from tea’s?

Coffee contains a unique polyphenol that is more active in reducing blood pressure, which is not present in tea. Both beverages have polyphenols, but coffee’s specific compounds show greater effectiveness in this particular health outcome.
