48 year old male, 215 lbs, exercise several times per week, take blood pressure reducing supplements such as garlic, coq10, olive leaf extract, vitamin e and many others, but blood pressure still remains around 140-170 over 90 - 105. No history of kidney or liver problems and in fairly good physical shape. Had bad accident almost 20 years ago with rods, plates, pins, wire wraps, etc. in legs & arms and had a direct drip into heart while in hospital. Could any of that be the problem?
