Fair questions
Does turmeric work?+
For joints, yes. The biggest review covered 29 trials.
Is turmeric safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
Why only 3 sources, when PubMed lists 1,345?+
The 1,345 is every paper that mentions turmeric in any way: animal studies, blood measurements, papers where it is a side note. The strongest sources are combined reviews, and each one already gathers every trial its authors could find. Our 3 cover 74 trials between them, and every one is linked above. Both counts are measured, not estimated.
