diabetes help

My father has tried most of the products but can not seem to keep blood Sugar low. Anyone recommend any protocol or other supplements used in conjunction with dr. S?

current protocol inludes : alpha lipoic acid, glucobetic, vit c and e, and dr. S's superfood and detox/liver-gb formulas.

I need another supplement to help or add on, any opinions? Diet is the best it can be currently and exercise is done daily.
