The Bundesinstitut für Risikobewertung (BfR) report evaluated the health risks associated with the intake of high-dose vitamin D supplements (bolus doses) taken at intervals of days or weeks, sometimes combined with vitamin K2. “The study demonstrated the safety of vitamin D supplementation and a statistically significant reduction in cancer mortality among people taking vitamin D, particularly after two or more years of supplementation,” Professor Eggersdorfer said. The combination of vitamin D with omega-3 reduced the odds of becoming pre‑frail, with no side effects like increase in kidney stones, hypercalcemia or GI symptoms. reveals that more than 50% of the study population had vitamin D levels below 50 nmol/L, which is rated by expert as cut off for vitamin D deficiency. The findings indicate that people with vitamin D levels below 30 nmol/L have an increased risk for CVD mortality, cancer and respiratory disease compared with people at levels above 50 nmol/L.
