Michael F. Holick: “…the concept that vitamin D is one of the most toxic fat-soluble vitamins has been instilled in the psyche of health regulators and the medical community…The evidence is clear that vitamin D toxicity is one of the rarest medical conditions…”
“… and is typically due to intentional or inadvertent intake of extremely high doses of vitamin D (usually in the range of >50,000-100,000 IU/d for months to years.)
