The Claim
Among adults with knee osteoarthritis, no nutritional supplement included in this analysis—Boswellia, curcumin, krill oil, collagen, ginger, eggshell membrane, or vitamin D—was associated with an increased risk of adverse events compared to placebo.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with knee osteoarthritis, the supplements Boswellia, curcumin, krill oil, collagen, ginger, eggshell membrane, and vitamin D did not lead to more adverse events than a placebo.
See the scientific wording
No nutritional supplement included in this analysis was associated with an increased risk of adverse events compared to placebo in adults with knee osteoarthritis, suggesting a favorable short-term safety profile for Boswellia, curcumin, krill oil, collagen, ginger, eggshell membrane, and vitamin D.
Compounds from these supplements block key inflammatory signals in the joint, reduce harmful chemicals that damage cartilage, and calm the immune system so it stops attacking joint tissue. This lowers pain and swelling, and helps the joint repair itself without causing side effects.
What the research says
1 studyThis study checked if common supplements like Boswellia and curcumin caused more side effects than a sugar pill in people with knee pain—and found they didn’t. So, they seem just as safe as nothing at all in the short term.
