A growing body of research suggests that certain everyday foods may help control blood pressure as effectively as some medications. Central to this are flavan-3-ols — natural plant compounds found in cocoa, tea, grapes, apples, and some berries. They not only lend plants their color and flavor but also appear to have potent cardiovascular benefits.
  • Natural blood pressure support – Flavan-3-ols, plant compounds found in cocoa, tea, grapes, apples, and berries, can lower blood pressure by about 3 mmHg on average and up to 6–7 mmHg in people with hypertension, similar to some medications.
  • Better blood vessel health – Regular intake improves endothelial function (blood vessel flexibility), helping protect against heart attacks and strokes even in people with normal blood pressure.
  • Practical daily dose – Benefits are seen with roughly 500–600 mg per day, easily reached with 2–3 cups of tea, 1–2 servings of dark chocolate, or a few apples.
  • Whole foods work best – Cocoa, tea, and fruits outperform supplements, likely because natural compounds in foods work together to enhance absorption and effectiveness, offering a safe, food-based way to boost cardiovascular health.

Why Dark Chocolate and Tea Could Be as Good as Pills for Lowering Blood Pressure

A major review analyzed 145 randomized controlled trials involving more than 5,200 participants. These studies tested flavan-3-ol–rich foods and supplements and measured their impact on blood pressure and blood vessel function. On average, daily intake of about 586 mg of flavan-3-ols — the amount in two to three cups of tea, one to two servings of dark chocolate, or a few apples — lowered systolic blood pressure by roughly 2.8 mmHg and diastolic by 2.0 mmHg. In people with hypertension, reductions were more pronounced, reaching 6–7 mmHg systolic and 4 mmHg diastolic — levels comparable to some prescription medications. Beyond lowering blood pressure, flavan-3-ols improved endothelial function — the ability of blood vessels to dilate properly — with an average 1.7% increase in flow-mediated dilation. This improvement occurred even in individuals with normal blood pressure, suggesting a protective role for blood vessels and a potential for preventing cardiovascular disease before it starts. Safety data were reassuring. Reported side effects were uncommon and mild, mostly limited to minor digestive issues. Importantly, whole foods outperformed supplements. While some trials used isolated flavan-3-ol compounds, the benefits tended to be smaller than those seen with natural sources such as tea or cocoa. This likely reflects the synergistic action of multiple compounds in whole foods, which can enhance absorption and effectiveness. These findings matter because high blood pressure is a major global driver of heart disease, even at levels not classified as full-blown hypertension. Yet clear dietary guidance has often been lacking. The evidence now supports a simple, practical, and enjoyable strategy: incorporating flavan-3-ol–rich foods into daily meals. Practical examples include replacing a sugary snack with an apple and a piece of dark chocolate or adding an extra cup of green or black tea. A target of 500–600 mg per day of flavan-3-ols appears sufficient to produce benefits. This can be achieved by combining two to three cups of tea, one to two servings of dark chocolate or cocoa, and several flavan-3-ol–rich fruits like apples, grapes, or pears. More research is needed to confirm benefits in people with diabetes, to clarify interactions with medications, and to explore how flavan-3-ols work alongside other healthy habits. But the evidence already suggests that food — not just pills — can play a powerful role in blood pressure control. Flavan-3-ols are not a replacement for prescribed treatment, but when added to a healthy lifestyle, they offer a safe, affordable, and delicious way to support heart health.
