Question: Would a seasonally low vitamin D intake and high calcium intake cause soft tissue calcification?

Chris: Yeah, okay. The end of this question is would the calcium simply be excreted due to the low vitamin D levels. Your vitamin D level being low, the first thing that's going to do and the major thing that's going to do is it's going to lower your calcium absorption. You would have more calcium excreted in the feces as a result of not absorbing it if your vitamin D level is low. However, a high enough calcium intake is going to more than compensate for that. It depends how low it is. If you live in northern Michigan and you're not supplementing with vitamin D in the winter, but you're outdoors a lot, your vitamin D is probably not going like rickets level low. It's probably dipping a bit. A calcium intake of 2,000 milligrams is so high that you're probably absorbing at least enough calcium.
