I am someone who has suffered from severe muscle and joint pain. I am in the process of gaining my health back. One thing to look for if buying glucosamine is to make sure it has a d in front of it. Check on the back of the bottle. D is far more utilized than regular and this product does work along with chondroitin.
Also Norwegian cod fish oil is great for the joints. You can buy any oil but oil from the fish in Northern Europe has hardly any chemicals and carcinogens. Most important is to keep juicing
and eating properly. I know that the body takes care of itself when given the proper food.
Avoid any acidic foods or juices such as spinach, chard, cranberry, plums and of course caffeine, alcohol, red meat and refined foods. As for a specific fruit or vegetable, the rest are all important. You need the whole vitamin package. You could also search online about a treatment called prolo-therapy. It has worked miracles for many.
Good luck my friend,
