Health Rack’s latest version of Glucosamine Sulphate tablets ,large white with a rough surface are difficult to swallow. I gave feedback by phone some days ago that I had almost choked trying to swallow this difficult tablet and while alone in the house. Luckily I coughed it back up. I have since cut a number of tablets in half for future application but this morning had difficulty swallowing the two halves now with one end sharp edged. I will now have to smooth off that end for safety’s sake. I will be buying no more. No one has replied since my previous phone call I suggest you go back to the smooth blue version you manufactured earlier. BH
