Can an aspirin a day keep the niacin flush away?

This small study aimed to understand if taking aspirin could prevent the skin flushing that often happens when people take niacin, a cholesterol medication. Nine healthy volunteers took either aspirin or a placebo for five days, then took a dose of niacin. Researchers collected their blood and urine to measure natural substances that might be linked to the flushing reaction. The goal was to gather basic knowledge about how these substances work in the body's cardiovascular system.
