What can I do if I suffer from arthritis?
Arthritis is treatable, I suggest you get a copy of my book and start following the habit changes one by one. As far as supplements go, yes glucosamine is good, but it is only part of the story. Look up on the website about a company called Mannatech and look at the product ambrotose, read up on it, I believe it is more complete then glucosamine. I am not one to take supplements except for ambrotose (in times of health stress) and colloidal minerals (TJ Clark is the best), go to your health food store and ask about it.
Apart from that food should be your medicine, cold pressed oils for your essential fatty acids, eggs for your protein, wheat grass for your vitamins and so on.
