My levels of 25(OH)D3 are optimal. It takes slightly over what the real average TUL should be because of my mass and apparently poor absorption.
Edit: Cortisol levels are fine. I also had a complete HPA/G/T workup by an endocrinologist. The results were unremarkable. I even had testing for pheochromocytoma, although this does not rule out other types of adenomas.
- rojeee 5y agoThat's interesting. Is there a paper I can read? Quite interested in this stuff. Cheers

- rojeee 5y agoThank-you for this.
- getpost 5y agoNo, even 5000iu/day is too much for some people, as previously discussed on HN at length. https://news.ycombinator.com/item?id=24261948 https://news.ycombinator.com/item?id=24261948
- stooliepidgin 5y agoAnd no to that too. RDAs try to be one-size-fits-all guesstimates. For Vitamin D3 in particular: "The model developed for UL derivation was summarized in 1998 (IOM, 1998), and it acknowledged that the lack of data would affect the ability to derive precise estimates." [0] Furthermore, an RDA and a UL doesn't work for D3 because the ranges across people don't harmonize to specific "safe" or "adequate" numbers for a given demographic. 1000 IU is too much for some people. [0] Blood tests trump RDAs. I need over 10k IU per day, but this could cause hypercalcemia, calcification of tissues, and/or calcium kidney stones in other people. 0. https://www.nal.usda.gov/sites/default/files/fnic_uploads//TolerableUpperIntakeLevels.pdf https://www.nal.usda.gov/sites/default/files/fnic_uploads//T...
