What does the evidence say about Curcumin Knee Pain Randomized Trial?

Updated June 2026

Quick Answer

Curcumin Knee Pain Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Results Compared to the placebo, VAS-101 was associated with greater improvements in the KOOS pain score (primary outcome measure) (β: 5.12; 95% CI: 0.47, 9.77; d = 0.62, p = 0.041), and mean daily pain ratings (F 3, 225 = 4.42; d = 0.55, p = 0.005).

Key Takeaways

  • 01Results Compared to the placebo, VAS-101 was associated with greater improvements in the KOOS pain score (primary outcome measure) (β: 5.12; 95% CI: 0.47, 9.77; d = 0.62, p = 0.041), and mean daily pain ratings (F 3, 225 = 4.42; d = 0.55, p = 0.005). [Lopresti AL (2026)]
  • 02In the VAS-101 group, 39.3% of participants reported feeling either much or very much improved, compared with 13.3% in the placebo group ( p = 0.019). [Lopresti AL (2026)]
  • 03Conclusions Conservative dosing of a topically applied curcumin-containing gel (VAS-101), administered every two days for 28 days, is associated with moderate reductions in knee pain in adults with knee osteoarthritis. [Lopresti AL (2026)]
  • 04Background The oral delivery of curcumin has been shown in several studies to have beneficial pain-relieving effects for the treatment of knee osteoarthritis. [Lopresti AL (2026)]

[Toumi Hechmi (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
