That's not entirely true. You can take too much as it is stored in body fat. From the Mayo Clinic:
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.Not discounting what he says in the article. The "D Hammer" has worked for me. But there is an upper limit to how much you should take.
Thank you. It needs said on every article here dealing with D3. Some on here are playing with fire. The bone pain is the process of leaching calcium out of your bones and entering your blood stream. If you have any blockages in your arteries these are the spots it accumulates. I had an artery scan many years ago and had two minor blockages. I was in my 50’s. Best 99 dollars I ever spent. I had another in 2016 and those two had become major and had three other minor ones. So it is not just hardening of the arteries. It sets you up for a stroke. I was put on the 50,000 IU pills and immediately experienced whole bone pain in my right thigh. I had to figure it out on my own, which says a great deal about the VA medical profession. Yeah, take high levels of the rat poison if you dare. Go ahead and play Russian roulette.
