Glucosamine is a ubiquitous and widely studied ingredient in many joint health products. I've written previous articles on the different types of glucosamine used in joint health products (sulfate, hydrochloride, and n-acetyl glucosamine).
A recent article (Vlad et al, 2007) supports my previous conclusions on the ingredient glucosamine hydrochloride. In this recent article, published in the medical journal, Arthritis and Rheumatism, the study others sought to explain the heterogeneity of clinical trial results on glucosamine. Essentially, they endeavored to explain why many randomized clinical trials on glucosamine have found that it works, yet some clinical trials have conflicting results. Essentially, part of the reason for this discrepancy is that the clinical trials on glucosamine products include trials on glucosamine sulfate and glucosamine hydrochloride. Among their explanations was the simple conclusions that "glucosamine hydrochloride is not effective."
Make sure that your joint health product includes glucosamine sulfate. Glucosamine sulfate is found in the Arthroleve formulation. Visit http://www.arthroleve.com/ for information on our latest offers! We now offer free shipping for our Home Delivery Plan customers.
