Some Joint Health Supplements Mislabeled: ConsumerLab.com

But some products don’t contain listed ingredients, are contaminated with lead, or do not break apart properly, according recent analyses by ConsumerLab.com, White Plains, NY.

Differential metabolic effects of glucosamine and Nacetylglucosamine in human articular chondrocytes

Alexander R. Shikhman, Diana C. Brinson, Jean Valbracht and Martin K. Lotz

Abstract
Objective—Aminosugars are commonly used to treat osteoarthritis; however, molecular mechanisms mediating their anti-arthritic activities are still poorly understood. This study analyzes facilitated transport and metabolic effects of glucosamine (GlcN) and N-acetylglucosamine (GlcNAc) in human articular chondrocytes.

Methods—Human articular chondrocytes were isolated from knee cartilage. Facilitated transport of glucose, GlcN and GlcNAc was measured by uptake of [ 3H]2-deoxyglucose, [ 3H]GlcN and [ 3H] GlcNAc. Glucose transporter (GLUT) expression was analyzed by Western blotting. Production of sulfated glycosaminoglycans (SGAG) was measured using [ 35 S]SO4. Hyaluronan read more…

D. Karthikeyan, MPharm, PhD; M. Vasudevan, MPharm, PhD; S. Narmadha, MPharm, PhD; and T. Sivakumar, MPharm, PhD

Purpose: Our purpose in this study was to compare the efficacy, tolerability, and safety of a multicomponent antiinflammatory preparation containing glucosamine hydrochloride (g hydrochloride) or plain glucosamine sulfate (g sulfate) with that of a nonsteroidal antiinflammatory drug (NSAID), aceclofenac, in the treatment of knee osteoarthritis.

Methods: Forty-five patients with active osteoarthritis of the knee joint were randomized to receive g hydrochloride, g sulfate, or aceclofenac for 12 read more…
