Be very careful with Dr. Christopher's formula if you are hypoglycemic. Several of the herbs have insulin like actions and directly lower blood sugar. Also the main ingredient Cedar Berry's nickname is "nature's insulin".
Not saying they can't be beneficial, but just watch your sugars.
Personally I tried the formula and it did absolutely nothing for me either way. My pancreas still continues to degrade, and still hurts badly at times. The pain radiates to the back and is very annoying.
