Definitely a D problem these days. Funny (not really) one of the nurses I work with came to me a few days ago, as she had heard rumors about me knowing of "supplements"
A few days prior she had been at her doctors office; he took the tests; vit D was very low. Everything else ok, even if she is tired and irritable most of the time, she says.
"but dont bother about it" the doc said. "Everyone are low in vit D"
She have been taking the cod liver oil, oily fish, as recommended, for months. It doesnt help, something else needed.
I sent her to a tanning bed.
