An approach to high blood pressure

The best approach to high blood pressure will of course depend on the cause.  Metabolic syndrome (chronic high levels of insulin with associated insulin resistance) is one well-documented cause of hypertension, as is diabetes.  The theory is that chronically high BG (even below levels considered diabetic) can damage nerves, including the autonomic nervous system, which is responsible for controlling blood pressure (among many other things).  In the long-term, the Paleo diet should help improve things by eliminating what may have been one aspect of the initial cause.

[[MORE]]There are many other causes too, though.  Calcium is required for muscles to contract, and magnesium is needed for them to relax – that includes the muscles in arterial walls, which, when they contract, raises your blood pressure.  Increasing your magnesium to the point of bowel tolerance for a few months helps some people.  Unfortunately, magnesium deficiency is wide-spread and often hard to correct.  Avoid magnesium oxide; amino acid chelates, such as magnesium orotate or aspartate are much more readily absorbed.  Time-release mag chloride (“Slow Mag”) is another option. Mag citrate (Natural Calm) is also OK, although you need to take more of it to get the same effect.

Another area that helps for some is nitric oxide (NO) releasers, such as arginine, ginkgo biloba, panax ginseng, resveratrol, green tea, garlic and quercitin.  NO is involved with blood vessel dilation.  Since NO is a strong oxidant, be sure to take extra antioxidants with NO releasers.
