Hello again,

Eyap, hows those Sens eh?

Like I mentioned there appears to be some debate about the supplements mentioned. The problem stems from our current capacity to measure the microscopic changes that occur with chronic degenerative diseases. Outcome measures use to analyse the effects of such supplements usually involve subjective pain scales, not entirely accurate for a clinical decision to be made. However, there appears to be clinical results that suggest certain therapies, or supplements do work for people.

Here is a summary of some recent studies into the supplements mentioned:
1. Glucosamine: Glucosamine Sulfate as opposed to Glucosamine HCL appears to be effective. Overall there is still much ongoing debate in regards to this.
Arthritis Rheum. 2007 Jul;56(7):2267-77.
Glucosamine for pain in osteoarthritis: why do trial results differ?

2. Same idea for Chondroitin: for Dr's their thinking is if some patients believe it works for them (placebo?) they don't see constant prescription as a faux pas.

3. MSM:MSM (3g twice a day) improved symptoms of pain and physical function during the short intervention without major adverse events.

4. Cetyl Myristoleate appears to help certain patients, however, research which has previously been done has not been followed up on this compound.

The key here is, if you can afford it, it may be beneficial for you to try these and see if they are effective for you. The problem is there is in fact conflicting evidence in regards to their effectiveness because studies almost always examine the subjective pain experience of the individual. Scientific equipment is not yet available for measuring and tracking the changes within the joint surfaces, although this may change in the future with recent advances in tracer technology.

The point of me mentioning these is that if you do go see a local nutritionist, you can at least be informed about the key compounds that are being touted as beneficial. If someone tries to hard line you on a certain compound, at least you are now aware. That is not to say a nutritionist probably will have an awareness of what compounds can improve bone health. Some of these include calcium, vitamins, and more recently evidence into creatine.

Most importantly, and I'd be amiss if I didn't mention this, Physical Therapy is probably your very best bet for maintaining joint integrity for years to come:

Physical therapy, including strength and muscle balance exercises as well as education about biomechanics of joint movement and ergonomics will probably be your best preventive course of action.

Best thing is too probably find yourself a Physiotherapist, and as well a Nutritionist who can sort out some preventative treatment program.
