High Blood Pressure and Vitamin C

Oxidative stress is linked with hypertension (high blood pressure).  Investigators were curious to know if the antioxidant vitamin C can lower high blood pressure, since it counters oxidative stress.

Thirty two people with untreated high blood pressure were given 3 grams of Vitamin C.  Blood pressure was significantly lower after treatment.  Certain types of nerve impulses stimulate the muscles that line blood vessels to contract, increasing blood pressure.  After vitamin C use, these nerve impulses diminished.

Citrus fruits are a good source of Vitamin C.  So are bell peppers, kale, and broccoli.  To get the amount of vitamin C used in this study, however, you’ll need a vitamin C supplement.
