I have a few readings before starting CNS of 95 glucose in the morning.In addition to 1 or 1/2 Centrum daily, I take 500 to 1mg of vitamin C. (based on Paul Jaminet's advice)My glucose levels while on CNS have been elevated. 110-125 consistently.According to Dr. Bernstein, C supplementation can give elevated glucose readings.I also found this, which says the same thing:http://diabeteshealth.com/read/1999/09/01/1630/high-doses-of-vitamin-c-supplement-increase-blood-glucose-levels/I am going to discontinue the C supplements and possibly the Centrum as well for 14 days to see if morning glucose levels fall.
