Effects of glucosamine + omega-3 on osteoporosis
Researchers in Germany conducted the first study of this combination.
The aim was to see if the combination is more effective than glucosamine alone.
First, the details.
- 177 patients with moderate-to-severe hip or knee osteoarthritis (OA) were randomly assigned to a treatment for 26 weeks.
- Group A: Glucosamine sulfate (1500 mg/day) + omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)
- Group B: Glucosamine sulfate alone
- Neither the patients nor researchers knew the treatment given — double blind.
- Evaluation was performed using the Western Ontario and McMaster Universities Arthrosis index (WOMAC) score.
And, the results.
- Based on the criterion of at least a 20% reduction in the WOMAC pain score there was no difference between treatments (92% Group A, 94% Group B).
- Based on the criterion of at least an 80% reduction in the WOMAC pain score, glucosamine sulfate + omega-3 was significantly better than glucosamine alone (44% Group A, 32% Group B).
- OA symptoms of 1) morning stiffness, and 2) pain in hips and knees at the end of the study were 49% vs 56% Group A, respectively; and 42% vs 55% Group B).
- Both treatments well tolerated over 26 weeks.
The bottom line?
There’s support for each component individually. Now there’s support for the combination, which should be followed by more research.
