The Study
Efficacy and Safety of a Novel Low-Dose Water-Dispersible Turmeric Extract in the Management of Knee Osteoarthritis: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial
This is a well-run experiment where people with knee pain were randomly put into two groups: one got a turmeric pill, the other got a sugar pill, and nobody knew which one they had. This kind of test can show if the pill actually helps, because it's fair and unbiased. We can say the pill helped reduce knee pain, but we can't say it cures knee osteoarthritis or that it works for everyone or for a long time.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Turmeric is a spice that has a natural chemical called curcumin which might reduce pain and swelling. This study tested a special turmeric extract (WDTE60N) that your body can absorb easily. People with mild knee pain took one capsule (250 mg) every day for 3 months, while others got a fake pill (placebo). The study checked if their knee pain and daily activities got better.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, these improvements are big enough to be felt by patients (clinically meaningful).
- 2For example, pain relief was above the minimum important difference of 8.4 points by day 45, and all quality-of-life scores improved beyond the 8-point threshold.
- 3The treatment was also safe with no serious side effects.
- 4People taking turmeric had bigger drops in pain scores (14.4 points) than those taking placebo (6.0 points).
- 5They also reported better everyday function and lower levels of inflammation in their blood.
- 6Improvements started within one week and continued for 3 months.

Turmeric (curcumin) quickly eases osteoarthritis pain.
A daily 250 mg supplement of turmeric extract with 60% curcuminoids reduces knee pain in adults aged 45–75 with mild-to-moderate knee osteoarthritis. In a double-blind trial, the supplement lowered pain scores by 14.41 points over 90 days, while placebo lowered them by 6.02 points—a 25.05% improvement compared to 10.57%.
In adults with mild-to-moderate knee osteoarthritis, a daily 250 mg turmeric extract supplement reduces pain and improves knee function more than placebo. Pain relief exceeds a clinically meaningful threshold starting at day 45, and functional gains exceed their clinical threshold by day 90.
Taking a low-dose water-dispersible turmeric extract supplement every day for 90 days noticeably improves pain, symptoms, daily activities, sports ability, and knee-related quality of life in adults with mild-to-moderate knee osteoarthritis compared to placebo.
In adults with mild-to-moderate knee osteoarthritis, taking 250 mg of a specific water-dispersible turmeric extract every day for 90 days lowers blood markers of inflammation, including CRP, TNF-α, IL-6, and IL-1β. The reduction is significantly greater than that seen with a placebo.
A 90-day study of 70 adults with mild-to-moderate knee osteoarthritis found that taking a low-dose water-dispersible turmeric extract (WDTE60N, 250 mg once daily) is safe and well-tolerated. Only one person had a mild stomach ache, and nobody had serious side effects.
