The most effective form of glucosamine is HCl, but it has been shown to elevate resting blood pressure. The demographic who are interested in joint health are also usually interested in low blood pressure, so very few HCl products are marketed. The difference isn't worth the worry.
Chondroitin has a synergistic effect with glucosamine. It is noticeable.
MSM definitely works. It is derived from a product called DMSO. Some still use DMSO directly on joints which does work but has some unwanted side affects and risks.
