I started taking a high doses of D a couple years ago and now have three rather large kidney stones (one 13cm x 8cm). Has anyone had this experience? FYI I take 50,000 6 days a week and my D level is 65. (I've had resections for crohns so I dont absorb everything).

Excessive vitamin D supplementation may increase the risk of stone formation by increasing the intestinal absorption of calcium, but there is no evidence that correction of vitamin D deficiency increases the risk of stone formation. http://content.karger.com/ProdukteDB/produkte.asp?Aktion=ShowPDF&ArtikelNr=000317196&Ausgabe=254382&ProduktNr=228539&filename=000317196.pdf

	Are you eating a lot of calcium-rich foods? – Bread-Eating Beelzebub Apr 11 2012 at 16:42
	Only broccoli(?) and almond milk which has twice the amount found in milk. – uberbulldog Apr 11 2012 at 16:50
	Did you mean mm instead of cm? Otherwise, that stone is as large as your entire kidney... – Nemesis Apr 11 2012 at 17:02

It certainly can happen.

You need to have sufficient Magnesium, (and Vitamins A & K) as cofactors to avoid this when taking large doses of D.

I don't know about this in general, but here's my anecdote. I'm susceptible to kidney stones -- I've had them at least twice, but not for several years now, including the period last year when I supplemented D heavily (10K IU/day for many months).

Has anyone developed kidney stones after taking vitamin d, especially large doses?
