Not likely that supplements will affect the pancreas. Some drugs do however... some used for diabetes cause pancreatitis.

I couldn't do anything when I had my long test. After the 2nd hour I crashed, ended up sweating and crying and trembling most of the time. They had trouble finding my veins so that was very painful for me. I can't imagine reading a book under the circumstances I had to go thru. (reactive hypoglycemia etc).

To get less painful fingers, try lancing with a very fine point ( I use Delica lancets with the Delica tool)..and do the upper sides of the fingers. I usually do the middle or ring finger on the left hand. Squeeze the blood down, by shaking your hand and then squeeze the finger near the palm and push the blood to the tip...it should get dark red. (if cold, warm them up in warm water). You'll get a good drop from the side of the finger and it hurts less and won't leave pain in the tips when you use the finger later in the day. The tips of the finger have more nerve endings and are more problematic for discomfort.
