Likewise, 23ng/ml while taking 2000iu/day of dry vitamin-d.
Switched to 5000iu +K2 in MCT oil, -- 8 months later I'm at 64ng/ml.
- rbjorklin 3mo agoAny noticeable difference how you feel health wise? Energy levels? Mood? Sleep quality?
- _0ffh 3mo agoNot the same person here, but a data point nonetheless. Before supplementing D3 I had a cold basically every year, sometimes twice a year. Since I brushed up my levels I average 1 cold in 6 years.
- ww520 3mo agoOddly, since the Covid time, I haven't caught a cold or flu once. I'm not sure it's the vaccines, the flu shots, or the less physical contacts on things overall. I still go to crowded places from time to time, like plane or train rides. May be the population in general have less cold or flu virus overall to go around.
- nullc 3mo agoUnfortunately too many other changes happened at the same time. I am enormously healthier now (in numerous measurable as well as subjective ways) but it may be that the D levels played no role.
- nicman23 3mo agofor me, i was so deficient that i would notice it the next morning. also probably not a placebo as the D supplement i am taking is not something my mind goes to 7 am pre coffee lol
- icedchai 3mo agoI switched from 2000 to 5000iu about 8 years ago. My levels went up similar to yours, but I don't feel much different!
