Yes, the primary factor in the formation of insulin resistance is a chromium deficiency.
Insulin will grab a hold of glucose then latch on to an insulin receptor. This allows the movement of the glucose in to the cell. If the receptor is closed though the insulin has no place to dock so it just floats around carrying the glucose instead of getting it out of the bloodstream. Chromium is what keeps those insulin receptors open.
Look for chromium polynicotinate, which is 300 times more effective than chromium picolinate and costs the same.
Magnesium and zinc also play important roles in blood sugar regulation. With the magnesium make sure it is an acidified form, preferably magnesium malate. Avoid magnesium oxide since it is poorly absorbed, neutralizes the stomach acid and burns the intestinal wall.
Keeping your weight down will also help since fat contributes to insulin resistance.
