Vitamin d : how many iu's of vitamin d is it safe to take long term without the risk of calcium being built up in the internal organs..thanks?

10,000 iu if with K2: Good question. Vit D enhances calcium absorption which can increase wish of calcification of arteries and tissues. It is considered safe to take up to 10,000 iu of D3/day; there is no evidence of toxicity at this dose. But it should always be taken with Vit K2, which helps assume the calcium you absorb goes to your bones. See http://tinyurl.com/la28k9k and http://tinyurl.com/hwa3xve See comment:
