"Calcium is maintained within a fairly narrow range from 8.5 to 10.5 mg/dl (4.3 to 5.3 mEq/L or 2.2 to 2.7 mmol/L). Normal values and reference ranges may vary among laboratories as much as 0.5 mg/dl."
Chances of kidney stones when blood calcium is within the above range is low. Making sure you drink when thirsty or otherwise are properly hydrated will minimize chances of kidney stones assuming you are healthy otherwise (no parathyroid issues). Your vitamin D level is NOT going to cause hypercalcemia. The notation on your Clinic report is just a typical 'warning' in the absence of additional information because your D level is not within their range ....

"Tests for Vitamin D Deficiency. The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. A level of 20 nanograms/milliliter to 50 ng/mL is considered adequate for healthy people. A level less than 12 ng/mL indicates vitamin D deficiency."
Any level above 50 is considered above normal ... i.e. too high. I don't follow this at all anymore. I consider the above information out of date. You would have to have itamin D levels way above 100 ng/ml in order to drive the body into hypercalcemia. 100 to me is the cutoff. I maintain my vitamin D level around 70. It has been as high as 85 and as low as 52. Over several years I learned what amount of vitamin D3 I need to take to keep where I am. Over the years the benefit to me keeping my D level above 50 (but below 100) has been zero colds, flu or getting 'sick' at all. And once I elevated my D level, my blast count fell to zero. I am a believer in the importance of Vitamin D in blood health (immune system).
Also I do take vitamin K2 (menaquinone aka MK-7). Vitamin K is NOT the same thing as vitamin K2. Your diet is almost certainly devoid of K2. K2 requires fermented foods like kimchi, Natto, etc. Do you eat those? If not, you are likely deficient in K2. By taking K2 along with D3, you pretty much insure any excess calcium uptake by the intestines (which vitamin D facilitates) is directed to the bones instead of soft tissue. This is the power of the D3+K2 combo. Our ancestors ate "dirty" food. It was loaded with bacteria and natural fermentation. This was the source of K2 and our bodies evolved to process and use this as nutrition. In our sterile society, K2 is no longer available as much. Hence the deficiency.
