After reading around I found that in some people chromium can lower blood sugar levels even further. It made me feel worse so I had to stop taking it.
Chromium does not lower blood sugar directly. Chromium is required from the proper function of insulin receptors. It the insulin receptors are not working properly then the insulin still grabs a hold of the glucose, but the insulin cannot carry it out the blood properly, which is where the term "insulin resistance" comes from. Therefore the chromium opens up the insulin receptors to allow insulin to do its job properly.
If the blood sugar is dropping below normal then there is likely a problem of chronic hypoglycemia, which is actually an adrenal issue.
