Not enough to say

Reviews of Bacillus subtilis, Bromelain, Ginger, Hordeum vulgare, Lignans, Oleuropein, Resveratrol, Vitamin C, Watermelon could not conclude either way on inflammation.

How this page is built

Each finding is the conclusion a set of systematic reviews reached on one outcome — whether an ingredient helped, made no difference, or could not be judged — with a sentence quoted from one review, checked to appear in its PubMed abstract. It records the direction, not the size, of an effect. Reviews run in populations such as people with cancer, pregnancy, surgery or children are left out, because applying them to a general reader would mislead. Evidence last refreshed September 2026.

Other goals

Educational only. A review finding a benefit on average does not mean a supplement will help you, or that it is safe alongside your medication. If you are treated for inflammation, talk to your clinician before adding anything.
