Hi Jenna, it's Tesco own brand. Glucosamine sulphate, 1500 mg, one a day. I was diagnosed with arthritic fingers in 2010, and was in a lot of pain, especially in winter, but these tablets have really helped over the last eight years, and I am not really in any more pain than I was back then.
However, I did recommend them to my friend who has lots of post menopausal aches and pains, and she said they made no difference. You do have to take them for a couple of weeks before they kick in though.
