Yes I take 200ug of Chromium Pictolinate everyday. I have done since I was diagnosed 3 months ago. Have no idea if it works though. It's rather like Cinnamon some studies say yes and others no. Like you I saw it on the link you gave. The one that does work if you can stomach it is Bitter Melon. For it to be really effective you need to take around 10g a day which is about two teaspoons of absolute yuk. The Indian name of Bitter melon is Karela and you can buy 100g pots of it off eBay.
