Glucosamine effective against wear and tear lower back?

Question:
I want to start taking glucosamine because my lower back bothers me lately and becomes worse due to wear. Now my question is: what do you recommend?

Answer:
Wear (osteoarthritis) of the vertebrae in the lower back is very difficult to treat unfortunately. It often takes a year or more before you’ll notice an improvement, and only when you use glucosamine and chondroitin simultaneously. And even then there’s no guarantee that it will work.
It has not been officially proven that osteoarthritis of the intervertebral discs can be treated with glucosamine and chondroitin. There are clear indications from scientists and practitioners that recovery is possible. The scientific evidence concerns an article (link: here) which describes how a man with intervertebral disc degeneration recovers by using glucosamine and chondroitin. The recovery is followed by making scans of the vertebrae (lower back). It appears that the vertebrae become thicker and resilient again over a period of two years. The slump is thus (partly) undone.

We can see this in practice too: customers report a reduction of their symptoms after a year. Unfortunately, the supplements do not work for everyone.

I apologize that I can not offer a brighter (and faster) perspective.
