Ingredient pairs in this product that have synthesised research evidence together.

Moderate evidenceVitamin E + Vitamin Cfor Reduced Pain· 3 studies
Across 3 studies, all reported beneficial effects of the combination of vitamin E and vitamin C on pain reduction, with effect sizes ranging from small to moderate (predominantly small). The median study duration was 60 days. The combination shows similar effects to vitamin E or vitamin C alone based on solo syntheses, but all studies tested the combination as part of a multi-ingredient formulation, precluding isolation of the specific contribution of these two vitamins.
