Oral-Health Supplement Ingredients: Evidence Library
A growing evidence map for ingredients commonly used in oral-wellness supplements.
How we grade ingredient relevance
We look at the type of study, human versus laboratory evidence, dose, delivery method, outcome measured and whether findings are consistent across research.
Xylitol
One of the most studied sugar substitutes in dental contexts, with mixed evidence for caries prevention.
Cranberry
Polyphenols studied in oral-biofilm and adhesion models.
Grape-seed extract
Investigated in several dental applications, with calls for more human research.
