That's a lot of scare mongering. It is extremely difficult to get hypercalcemia - a normal person would have to ingest 10,000 IU of D3 every day and even then it wouldn't be guaranteed. It is possible to take too much D3 but it is very difficult to achieve this. You basically need to go insane and take handfuls and handfuls of those golden capsules every single day for weeks and weeks. May I ask what your 25-(OH)D level was? This is the first mistake that people make: just taking D3 willy nilly without testing their level to see how much, if any, they need to supplement. btw an optimal D3 level is much higher than that which most doctors recommend because the old standard was for bone health but recently (past 20-35 years) more and more studies have shown that to get optimal health benefits such as optimal immune system function or lower cancer risks, you need much much higher levels than those suggested for bone health.

> It is extremely difficult to get hypercalcemia Not really. You just have to be predisposed to getting it. I don't really understand what your point is exactly. You're talking about elevated D3 like it's the same thing as a high Ca2. And that upping D3 doses turns D into Ca. Serum D is usually not elevated in this case. In hypercalcemics, the issue is elevated Ca2+ not D3. D3 merely improves the efficiency of Ca uptake, which is usually not a problem as most people will dispose of extra Calcium through their kidneys and urine. Hypercalcemics don't eliminate it fast enough (usually due to improper parathyroid signaling) and it builds up in their bloodstream. So excess D3 just exacerbates an existing issue. I haven't tested as irregular for thyroid or parathyroid issues (I get tested every year due to a long family history) but it's likely to be the cause. My dietary intake of calcium is virtually unchanged, but if I up my D3 intake significantly (sun exposure or supplements) it's likely that I'll also end up with elevated Ca2+ and have to cut both until I urinate it all out. I do actually have to know this stuff and be aware of it since it can literally kill me. Thyroid and parathyroid issues are surprisingly common (especially among women) so people taking lots of D supplements should just be on the lookout for similar symptomology. It's not hard to treat once you're aware of it. But it can be unfun trying to figure it out.
