Theobromine, present in the cacao tree ( Theobroma cacao ), plays a similar role. And the caffeine/theine in tea plants serves the same purpose: to repel or kill insects that attack the plant. The point at which caffeine intake may cause harm to the cardiovascular system is not readily identifiable in part because data on the effects of daily intakes greater than 600 mg is limited. Note that theine, produced by the tea plant ( Camellia sinensis) and present in tea, is actually just caffeine: the two are chemically indistinguishable. The available literature suggests that cardiovascular effects experienced by caffeine consumers at levels up to 600 mg/day are in most cases mild, transient, and reversible, with no lasting adverse effect. Truth is they’re the same molecule, however, the effects of tea are significantly different from those of coffee. This report attempts to understand where the delineations exist in caffeine intake and corresponding cardiovascular effects among various subpopulations. Save Is there caffeine in tea Caffeine and theine are known for their stimulating effects. ![]() Caffeine intake has been associated with a range of reversible and transient physiological effects broadly and cardiovascular effects specifically. This report evaluates the scientific literature on caffeine with respect to potential cardiovascular outcomes, specifically relative risks of total cardiovascular disease (CVD), coronary heart disease (CHD) and acute myocardial infarction (AMI), effects on arrhythmia, heart failure, sudden cardiac arrest, stroke, blood pressure, hypertension, and other biomarkers of effect, including heart rate, cerebral blood flow, cardiac output, plasma homocysteine levels, serum cholesterol levels, electrocardiogram (EKG) parameters, heart rate variability, endothelial/platelet function and plasma/urine catecholamine levels.
