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

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

Did you mean mm instead of cm? Otherwise, that stone is as large as your entire kidney...

Only broccoli(?) and almond milk which has twice the amount found in milk.

Are you eating a lot of calcium-rich foods?

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).

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.
