Hi Keith, I don't think it's the magnesium in celery that is necessarily responsible for the blood pressure lowering. I'm not sure what it is but I don't think it's the magnesium. Other food sources of magnesium are much higher such as nuts or cocoa powder or certain brands of mineral water. But if I was going to try to lower bp with magnesium, I would try either of the two products I mentioned -- Natural Calm or Magna Calm dissolved in hot water before bed. Supplements aren't paleo but neither are all the modern stressors and depleted soil of the modern world which make many of us low in magnesium. **************Great Deals on Dell Laptops.
