I doubt you can tell me that your vascular system have been tested “on every level” to know! When a stroke or heart attack shows up… or a gastric issue which can be debilitating for a very long time.. or an allergic reaction like I had, it’s too late. It’s not recommended for older folks. You should look up the terrible consequences of using Motrin at “high doses@ on a sustained basis. As you can tell- I am not a fan. The only reason some of these things stay on the market is politics and contracts and cheap medicine for people after my experience. I also got Vioxx toxicity. That stuff was left long on the market after it was found dangerous and caused heart attacks. Doctors recommended it all the time. I took that too!
