“Healthy adults currently enjoying the benefits of caffeine as a pre-training or pre-competition routine have little reason to be concerned about its blood-clotting potential,” he added.
However, those with poor cardiovascular markers, such as high blood pressure, high cholesterol, or a history of smoking, may want to avoid caffeine around their workout.
The link between caffeine and blood clots has been documented elsewhere.
