The Claim

Turmeric preparations, including conventional curcuminoid extracts, bioavailability-enhanced formulations, polysaccharide-rich extracts, and combinations with active drugs, appear to reduce knee osteoarthritis pain in adults compared with placebo, as measured by the WOMAC pain index, with mean reductions ranging from 2.5 to 4.0 points on a 0–20 scale; however, the certainty of evidence is low, so the true effect may differ.

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.

Cause and effect
1 study reviewed
In plain English

In adults with knee osteoarthritis, turmeric preparations reduce knee pain by 2.5 to 4.0 points on a standard 20-point pain scale compared with a placebo.

See the scientific wording

Compared with placebo, turmeric preparations — including conventional curcuminoid extracts, bioavailability-enhanced formulations, polysaccharide-rich extracts, and combinations with active drugs — appear to reduce knee osteoarthritis pain as measured by the WOMAC pain index in adults, with mean reductions ranging from 2.5 to 4.0 points on a 0–20 scale; however, the certainty of evidence is low, so the true effect may differ.

Why this might work

Turmeric contains natural substances that lower inflammation in the knee. These substances stop the joint from making pain and swelling chemicals, and they protect the joint from oxidative damage. This reduces knee pain.

1 study

  1. Study: Effect of turmeric products on knee osteoarthritis: a systematic review and network meta-analysis

    The study tested turmeric supplements against fake pills in people with knee arthritis and found that turmeric reduced pain by about 2.5 to 4 points on a 20-point scale, just like the claim says. The researchers also agree that the evidence isn't very strong.
