I’m about to find out how I get my “25 Hydroxy Vitamin D Level” greater than 25 and what the heck a “zinc taste test response” is
~~~~~~~~~~~~~~~
Note that the type of Vitamin D (or test for it) he talks about is 25-Hydroxy Vitamin D and the level is greater than 55 (maybe a typo but you wrote ‘25’).
“25-Hydroxy Vitamin D level greater than 55”,
Towards the end of last year, after taking 2500iu of Vitamin D for 6 months, living in a very sunny location, an outdoors person every day and in healthy shape, I had my D tested and it came in at 30. Doc wasn’t concerned and I learned that 30+ is acceptable. Went on Medcram and Dr said 50-60 is where you want it. Doubled down to 5000 since and need to get it retested, thanks for the reminder. Had never been on Vit D prior to covid, so almost certain was D deficient.

You’re right, it looks like the 55 refers to ng/mL
“The normal range of vitamin D is measured as nanograms per milliliter (ng/mL). Many experts recommend a level between 20 and 40 ng/mL. Others recommend a level between 30 and 50 ng/mL.”

And you can take a lot of D3 (50 mcg = 2,000 IU):
“In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe.”
