Research shows aspirin supplement more effective at night

NEW ORLEANS People who take 81 mg of aspirin everyday to help keep their blood pressure in check would do better to take that aspirin in the evening, according to research that was presented here before the American Society of Hypertension’s 23rd Annual Scientific Meeting and Exposition, the New York Times reported Tuesday.

The hormones and other chemicals that aspirin acts on are most active at night, the researchers reported.

As part of the study, researchers followed more than 240 patients diagnosed with pre-hypertension over 90 days. One group took aspirin in the morning, one during the evening and a control group did not take aspirin during the study. The researchers also tracked physical activity.
