Cloth, I am not disagreeing with you but have some serious questions. You say that pulse pressure, the difference between the systolic and diastolic should be around 40. Ummmm, the AMA and the Mayo Clinic websites both state that 120/60 is where BP should be. That is a 60 point difference.
I just took my BP and it is 130/70, a 60 point spread. My wife who is a runner has a BP of 110/55, again a 55 point difference. To meet your criteria of a 40 point spread, you would need a normal BP of 120/80. The diastolic is borderline Hypertensive.
For the record, when I stated that the gal at the store where I get my vitamins and stuff from knows her shit, I meant with her products. Only a fool would take medical advice from a cute chick with great knockers at a vitamin store.
Although antidotal, I still stand by my statement that the addition of the magnesium from the ZMA to my diet help lower my BP. Magnesium supplements have been used to lower BP in Europe for years.
Magnesium is a muscle and vascular relaxer. If you are running real high numbers, it will not help. And could be dangerous. But for us borderline types it may help. The best thing we can do to lower BP is still lose weight if fat, don’t smoke (like me and my half a pack a day habit) and work out. Yes, I need more cardio, but I find it boring as hell.
Also, that guy who was calling out a diastolic of 100+ needs to have attention fast. If his systolic is in the 180+ range, he is heading down the road to a stroke or heart damage. I agree that he needs to get a stress test and some good medical advice/attention.
