It's my understanding that "overdosing" on Vitamin D is very difficult. I take 5000 IU every morning. Do you have links to the research you found?

- j_s 14y agoFrom Steve Gibson's Vitamin D 'fan page' http://www.grc.com/health/vitamin-d.htm http://www.grc.com/health/vitamin-d.htm: John Jacob Cannell, M.D. and executive director of the Vitamin D Council has this to say about Vitamin D Toxicity: http://www.vitamindcouncil.org/vitaminDToxicity.shtml http://www.vitamindcouncil.org/vitaminDToxicity.shtml The Merck Online Medical Manual ( http://www.merck.com/mmpe/sec01/ch004/ch004k.html http://www.merck.com/mmpe/sec01/ch004/ch004k.html ) has the following to say: “Because synthesis of 1,25(OH)2D (the most active metabolite of vitamin D) is tightly regulated, vitamin D toxicity usually occurs only if excessive doses (prescription or megavitamin) are taken. Vitamin D 1000ug (40,000 IU)/day produces toxicity within 1 to 4 months in infants. In adults, taking 1250 ug (50,000 IU)/day for several months can produce toxicity.”
