What Causes Elevated RDW?

I recently had blood work done and the 1st I had done my hemoglobin hematocrit mcv mch and mchc were all low with an elevated rdw. I was put on iron and have been taking this until my recent labs which shows that everything is restored to normal except my RDW. What could be causing this. I was also on the first set of blood work deficient in B 12 which I have been taking injections for and now have a normal level.

Elevated red cell distribution Width (RCDW) is associated with early iron, vitamin B12, or folate deficiency.
