PROBLEM TO BE SOLVED: To obtain a glucosamine-containing tablet having a good shape stability with small unevenness in tablet mass to solve the problem that a glucosamine crystal powder has a physical property which is hardly to obtain a hardness, thereby the shape stability of a resulting tablet is low, and causes a reduction in commodity value by a breakage in the distribution process, and the flowability of a crystal powder is generally poor, thereby homogeneous filling to a mortar of a tableting machine becomes poor to cause a defect such as unevenness in tablet mass.SOLUTION: The invention is a tablet containing glucosamine, devils claw, valine, leucine, and isoleucine.
