Glucosamine - What is the best source

Hello,
I am new to the curezone and having a problem with a torn Meniscus in my knee.
I wish to heal it naturally and not have surgery. I have been reading that glucosamine is one of the better substances to aid in healing.
Does Dr. Schulze through the American Botanical Pharmacy have a glucosamine formula? I of course want the best.
If this is not available through ABP or Dr. Schulze , then where is the best place to obtain it and under what brand name? Tweet
