RESEARCH QUALITY ASSESSMENT:
- All studies were randomized, double-blind, placebo-controlled trials, which are considered the gold standard in clinical research.
- Sample sizes varied, with the largest study including 1,583 participants, providing robust data.
- Some studies had longer durations (up to 36 months), allowing for the assessment of long-term effects.
- Further research is needed to clarify the efficacy of glucosamine in different forms and dosages, as well as its effects on various types of osteoarthritis.
