- Low evidence3 studies
Across 3 studies, 2 reported beneficial effects (one large, one moderate) and 1 reported a neutral small effect. The predominant effect direction is beneficial, with mixed effect sizes (small to large).

Most studies did not specify dose or population, limiting generalizability.
