However, adverse effects are possible with intakes greater than 3000 mg daily, including reports of diarrhea, increased formation of kidney stones in those with existing kidney disease or history of stones, increased levels of uric acid (a risk factor for gout), and increased iron absorption and overload in individuals with hemochromatosis, a hereditary condition causing excessive iron in the blood. https://f004.backblazeb2.com/file/pkrkkl/herbalcolonicscomplex/colonics/What-Is-Vitamin-D-Deficiency.html
