# The Best Teas to Drink to Lower Heart Disease Risk, According to Experts
Green and black teas contain compounds called catechins and theaflavins that reduce inflammation and improve cholesterol levels, key factors in heart disease prevention. Research shows regular tea drinkers have lower rates of cardiovascular events compared to non-drinkers.
A 2024 meta-analysis published in the European Journal of Preventive Cardiology examined 195 studies and found that consuming three cups of tea daily correlated with a 21 percent reduction in heart disease risk. The effect appears strongest in green tea, though black tea also shows protective benefits.
White tea and oolong tea deserve attention too. These varieties contain similar beneficial compounds and demonstrate cardiovascular benefits in observational studies, though less research exists compared to green and black varieties.
The mechanism works through multiple pathways. Tea polyphenols improve blood vessel function, reduce blood pressure, and lower triglycerides. A study from Boston University School of Medicine found that tea drinkers showed improved blood vessel elasticity within weeks of consistent consumption.
However, medication interactions matter. Tea's caffeine and vitamin K can interfere with certain drugs. People taking blood thinners like warfarin should maintain consistent tea consumption and inform their doctors, since vitamin K affects medication effectiveness. Those on beta-blockers or taking certain supplements should discuss tea intake with their healthcare providers, as caffeine sensitivity varies individually.
Herbal teas like hibiscus show promise for blood pressure reduction but lack the catechin content of true teas derived from the Camellia sinensis plant. Preparation method affects benefits too. Steeping tea for three to five minutes extracts maximum antioxidants without over-extraction of bitterness.
Drinking three to four cups daily appears optimal based on current research. More isn't necessarily better, and
