How we rate the evidence
Health claims are easy to make and hard to prove. Every benefit on this site carries one of three labels, so you can see at a glance how much weight to give it.
Several good studies in people agree, or an official health body states it.
Some human studies support it, but they are small, short or mixed.
Only lab or animal studies, or traditional use. Not shown to work in people.
