Be careful with the Glucosamine if you are TTC. Studies done recently are showing that glucosamine can make the embryo think it that the mother is a diabetic and reacts accordingly (Diabetes being an auto-immune disease like arthritis)......Women have been reporting miscarriages. I only found this out while having some blood taken for IVF on Wednesday and the nurse drawng the blood had three miscarriages before they worked out what was wrong...she stopped taking it and is now 16 weeks pregnant.....so just keep that in mind
