Hello all I (M22) have been on a weight loss journey over the past year and a half and have gone from 305 to 240. However I noticed that my neck is still super dark. My face still swells after anything fast food related, and my A1C is still high and hangs around the 5.9 range. I know I’m still not at a very healthy weight but part of me thinks that I’ve hit a bit of a blockade due to my insulin resistance. I wanted to know if anyone here has ever taken berberine and has it been effective at lowering A1C? I feel like along with continuing my diet and exercise it could be the thing to help me break through this plateau and finally lighten my neck and underarm skin tone and texture.
