I can't believe it, but the author failed to mention the use of MSM (Methyl-Sulfonyl-Methane) for joint health! MSM is one of, if not the best, supplements you can take for joint health. It has helped me tremendously in keeping my shoulders and elbows feeling good. I use to have all sorts of shoulder and elbow issues (and still do once in a while but that's mainly my fault with lifting too heavy), but ever since I start taking mass dosage of MSM (10 grams daily), it feels much better. MSM is has a whole host of benefits such detoxification, anti-inflammation, and faster muscle recovery after exercising .
