Yet again, I want to point out that FORM MATTERS. Are we talking b12 as methylcobalamin or cyanocobalamin? Are we talking D as D2? D3? No findings matter without specifying form, and I didn’t see any of that in the source article.
“Daily intakes of 11 vitamins were estimated using the multiple source method to account for within-person variation from two 24 -h recalls, incorporating both food and supplement contributions. Total vitamin intake was calculated as their sum.”
I couldn’t understand so much of the methodology of this paper so it doesn’t really help much to me.
So many potential confounders that aren’t really explained. Sort of p hacking also.
My latest vitamin D test results are in: 69 (up from 42 a year ago) after taking calcifediol 30 mcg (3 pills of vitamoreD) per day for 2 months. I was previously taking 2 pills (20mcg) per day for 10 months. (no test in between; just a hunch). I’ll stay with the higher dose and recheck in a few months to see if that’s my dose or I need to back off.
