Vitamin D is a topic where popular media and commercial interests often overshadow evidence. The official guidelines used by national health systems converge on a small set of practical recommendations[1]. This guide cites WHO, NIH, USDA, EFSA, and MHLW only, ignoring commercial supplement marketing.

3. Common Myths vs Evidence
“Just take supplements” — Most healthy adults meet needs from food per NIH ODS guidance[2].
“One superfood fixes everything” — HSPH and Cochrane reviews show food patterns matter more than individual items.
“Natural = safe” — EFSA risk assessments show many natural substances have safe upper limits.
“Genetic testing reveals my optimal diet” — The evidence base for nutrigenomics-driven personal diets remains limited per Cochrane reviews.
“Detox cleanses remove toxins” — The liver and kidneys handle this. NHS Behind the Headlines: no robust evidence.
