i take 162.5mg 2x ed to keep my blood on the thinner side for better nutrient delivery. this is also monitored by my doctor. the negative effects of the asprin are less than any blood thinners. what is considered to be a normal healthy daily asprin dose is the low dose asprin i think its around 80mg. asprin at the right dosage is good for your heart. if you are into any strenous sport steroids or not you need to worry about heart health and do what you can to protect it. ask your doctor about it next time you see him.
