No: 60,000 iu of Vit D a month averages to 2000 iu/day which is not high at all. Most adults need 5-8000 iu/day to achieve optimal blood levels of 50-80. 60,000 iu/month is not close to being able to create D toxicity and not known to cause kidney problems. Calcium is also safe though might increase risk of kidney stones. I advise taking Vit K with Vit D and Calcium- see http://tinyurl.com/4rqhnn4
