Research-supported combinations

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

Low evidenceVitamin E + Vitamin Cfor Reduced Pain· 3 studies
Across 3 studies, all reported beneficial effects of the Vitamin E and Vitamin C combination on pain reduction, with effect sizes ranging from small to moderate and all findings statistically significant. Compared to Vitamin C alone (moderate evidence, small effect), the combination shows a similar directional benefit but the limited number of studies precludes a definitive comparison. The median study duration was 60 days (reported in 1 of 3 studies). No form data were reported for either substance.
