I am on Metformin 850mg. Also taking EPO and triple soy lecithin. My questions are as follows:

(I have decided to take 400mcg of Chromium Picolenate per day)

1) Is it better to take Chromium Picolenate 200mcg twice a day or 400mcg once a day?
2)Can I take 400mcg of Chromium Picolenate at night? Cos I take my Metformin in the day.

Hoping anyone here can help...
