A few months ago I ran some labs and my VD 25 OH was low 18. My 1,25 D was 47, on a scale of (32-72).
I began supplementing a topical D3 in the navel. I just re-ran my labs and my 25 OH came up to a 44, however my 1,25 D shot up to 100 (H). Ray Peat on the Kate Deering Vit D episode frequently re-assured that 1,25 D will go down when 25OH comes up. He mentioned how 25OH and 1,25 D is akin to the T3 and TSH for thyroid.
I find it interesting that the anti-VD people stated that if you supplement D3, it WILL increase 1,25 D. Which is supposed to be bad, and that is why they say do not supplement with D3. Any thoughts would be appreciated.
By the way, when my VD was 18, I did not feel any negatives. I found that just several years ago, the reference ranges for 25 OH were much lower, so "they" have manipulated the ranges just like cholesterol and prolactin.
