It sounds as if some in here have been completely unaware that the glucosamine question was settled years ago. Just as with niacin (for cardiovascular), vitamin E (for cv), saw palmetto (for prostate), and other naturally occurring substances, they work so well that the FDA has approved them just like they do proprietary drugs. Problem is, since these substances cannot be patented, and they are not drugs, the FDA cannot approve them as such, so the drug companies rush to find unique ways to deliver them (ie: sustained release). Or, they put them into some sort of combination that gets the FDA involved and makes the products worth promoting for a profit. When they accomplish this with glucosamine, you'll see the marketed natural product in your doctor's office with serious promotional dollars behind it (and the corresponding increased price as a result of their investment).
When one says they are skeptical, maybe they mean for their own use. For example, being skeptical that an aspirin will take care of a particular headache, or that the 5-day antibiotic your doctor gave you won’t require another course. It’s not a question of overall efficacy, but whether you’ll be one of the few for whom it doesn’t work.
To the question, ‘If something is so good, why isn’t everyone using it?’ Is that a serious question? EVERYONE in the whole world knows smoking causes cancer. Using this logic, it must not be true because otherwise, everyone would quit.
It is an established fact that condoms virtually stop most STD’s. Wait, that must not be true or else everyone would be using them.
It is an irrefutable law of nature that your risk of dying of a heart attack is virtually eliminated if your total blood cholesterol is less than 150. Since half of the US population currently measures over 200, it can’t be true, right? Otherwise EVERYONE would get their cholesterol below 150!
Same goes for weight loss, exercise, etc. There are countless things that are good for us that are heeded by only a minority.
Untold thousands died of scurvy in the 17th century while waiting decades for the British government to pronounce that vitamin C could prevent it.
Whether or not the majority goes along with something is certainly NOT always a measure of veracity nor importance.
It is one’s right to belong to the frequently ignorant majority—-the trick is to just avoid the facts.
P.S. Jyarddog, I'm glad to hear you'll at least try it.
