Query: Wonderful Health Aid

Comfort MSM has been a wonderful help for my standard poodle which is ten years old. Her arthritis was so bad that on cold days she could hardly stand up and had difficulty walking. Since I started giving her the tablets she is not only getting up easier but she is more nimble. She also loves the tablets! I've been giving her the tablets each day with Fish Oil and she's doing great! Thank you Comfort MSM!
