It's bad enough when mainstream doctors are ignorant about natural remedies.

But what's much worse is when they out-and-out lie about them -- like all the doctors who tell their osteoarthritis patients not to bother with glucosamine and chondroitin.

This bad advice means millions of patients suffering from the pain and misery of osteoarthritis never try the one thing that might actually help them.

It's a crime, if you ask me, because there's more science to back glucosamine and chondroitin than there is for most of the drugs commonly given to osteoarthritis patients (and your doctor probably knows it, too).

And now, we've got even more as a major new study confirms that these two supplements taken together can slow the narrowing of joint space inside the knee.

That narrowing space is caused by the loss of cartilage, or the cushion that protects your knee. The more cushion you lose, the more pain you feel as the joint starts to grind itself to dust.

Over the long term, that loss of space is what ultimately sets the stage for debilitating and even crippling knee pain.

But if you take glucosamine and chondroitin, you could slow that process, protect your knees and stop the pain before it starts, according to the new study in the Annals of Rheumatic Diseases.

And let's see those mainstream doctors try to dismiss this study, because it meets the so-called gold standard in every possible way: It was long-term, double blind and placebo controlled.

After two years, the patients given 1,500 mg of glucosamine sulfate and 800 mg of chondroitin sulfate per day saw their joint space narrowing improve by 0.1 mm.

I know what you might be thinking. An improvement of 0.1 mm doesn't sound like much.

But God didn't put much extra room inside our bodies when He designed us, and the knee is packed more tightly than a city bus at rush hour. Inside your knees, a difference of 0.1 mm could be the difference between comfort and misery.

Of course, nothing works for all people, all the time, and that's as true for glucosamine and chondroitin as it is for anything else. Some people have great results, some are disappointed and in some cases it can make almost no difference at all.

Don't give up, and don't turn to pain meds or even surgery -- because there are other natural options out there, including collagen.

I recommend a form called UC-II.
