The Claim
Some believe that taking excessive amounts of Vitamin D will automatically improve mood and energy levels. This assumption is often based on anecdotal experiences and the idea that higher doses lead to better outcomes.
Origin
This misconception is fueled by marketing of supplements promoting mood enhancement and energy boosts, as well as individual testimonials.
What Science Says
Research suggests that while Vitamin D is important for mood regulation, more is not always better. A meta-analysis showed that supplementation only significantly improved mood in individuals with low baseline Vitamin D levels; those with adequate levels did not experience significant improvements (effect size: small to moderate).
Verdict
Partially True
