Evidence notes
Good clinical evidence for anti-inflammatory and joint health benefits in multiple RCTs, though bioavailability remains a limitation without absorption enhancers. Extensive mechanistic research supports safety and efficacy. Grade reflects established but somewhat modest effect sizes in some populations.
Grade B: Some human trials support key claims; further confirmation needed.
