Bayer is no different than any other aspirin. What you’re paying more for is the name, “Bayer”.
Look it up. Bayer doesn’t have a patent on ASA. (Acetylsalisilic acid). Any drugstore brand you can buy is exactly the same thing.
It’s the same with “Tylenol”. Some folks think that off brands aren’t the same thing. LOOK AT THE INGREDIENTS on the bottles. It’s all acetaminophen. You just pay more for the brand name.
AND...
Make sure it isn’t manufactured in CHINA.
