Scientists test aspirin to stop Vitamin's red face side effect

This small study aimed to understand if taking aspirin could prevent the skin flushing (redness and warmth) that people often get from taking niacin, a vitamin sometimes used for cholesterol. Researchers gave healthy volunteers either aspirin or a placebo pill for several days, then gave them a dose of niacin. They collected blood and urine samples to measure natural body chemicals that might be involved in the flushing response. The goal was to gather basic knowledge about how this reaction works, not to provide a treatment.
