[Hidden-tech] Caution about excessive doses of Vitamin D supplements

[Stephen Michel]

In addition to the benefits of vitamin D, anyone supplementing at doses 
above ~2000 IU daily should be aware that prolonged supplementation at 
high doses can lead to harmful blood-calcium levels. What's "high 
doses"? It **very much depending on your individual body,** but almost 
nobody will have a problem below 2k IU (note that multivitamins & other 
supplements may also include vitamin D).

My source is these social media comments by a [person who claims to be 
a] parathyroid surgeon (parathyroids are the glands that regulate your 
calcium levels). https://news.ycombinator.com/item?id=24063443
She also has a blog with more information on the topic
