I live in England, UK and I have used Chromium Picolinate for many years and it is an every day part of my life. It was my main supplement in helping me lose over 5 stones, over a gradual time. I don't cut out my favourite foods, although I do monitor what I eat and I take exercise 3 times a week (cycling or walking) and to this day, I have not regained the weight I lost. Please bear in mind that weight should be lost over time and not approached with crash dieting in mind, so patience will benefit you in the long term. This is one of the top brands of Chromium Picolinate and the value is exceptional and I can't speak highly enough of Iherb, as an International service.
