Fast delivery (within 3 days). I'm using the Berberine as a supplement to losing weight combined with Lipozene. I started out with a different brand of Berberine but was looking for a supplement that I would only have to take once every day, which I can do with this brand. Loosing the first 20 lbs. seems to be the easiest weight to loose but it becomes harder afterwards. I prefer to loose between 5 to 8 lbs. a month, that way I can maintain my overall body weight. I'm disabled and therefore can't go to a gym and do a daily work out routine, but I can do certain things around my house, like cleaning, laundry, etc., that helps me sweat and burn calories. The Berberine gives me a nice energy boost plus helps with controlling my sugar cravings (I love chocolate). Combined with eating healthy meals that include fresh vegetables and fruits. I have lost close to 30 lbs. so far and hope to loose another 25 lbs. before the cold weather arrives, which hampers my ability of working out and sweating at least 1 hour a day (in increments) severely. I should hopefully be able to maintain my new body weight but tend to gain some weight during the cold season due to the limited supply of fresh vegetables and fruits. I will continue to use both the above mentioned Berberine from Bebefen and Lipozine together until I feel that I have reached my set goal of 175 lbs. or are unable to loose any more weight. The Berberine will always be a part of my live since I have type 2 diabetes and it enhances insulin sensitivity, lowers the production of glucose in the liver, and helps to transfer excess glucose into cells. I was diagnosed with liver fibrosis a couple of months ago and added berberine and inositol to my daily regime to help my liver with the milk thistle, artichoke, and curcumin that I have been using for years.
