And the answer, according to a new publication, is…aspirin. Good old acetyl salicylic acid. PaleoPathologist has been taking an aspirin a day for many years; I use generic enteric coated “baby aspirin” (75 mg) because it seems to work as well as anything and costs basically nothing. As the article states, higher doses don’t seem to add much except side effects. The most common side effect is stomach upset or even gastritis and bleeding. As always talk with your doc about this since some people have higher risks of bad side effects.
