What can cause vitamin D deficiency? (except the inadequate exposure to the Sun)

"Vitamin D" is actually a hormone produced by the kidneys and by the skin, which is an organ, upon exposure to sunlight. If your kidneys don't make enough of it, on their own, then your immune system could be compromised, (if you don't get much sun). Vitamin D3 and Vitamin D2 are the most important kinds.

Mushrooms are the only plant based source, if you like mushrooms. For your own safety, you don't want to eat fatty fish such as salmon more than twice a week because of the danger of mercury poisoning.

There are a large range of benefits provided by Vitamin D, and a deficiency could result in a weak immune system and in chronic depression.

@4meAndyou OMG I did not know this except recently when I read in an article that vit D deficiency is associated with recurrent respiratory tract infections 😨

@assemblingaknob Yup. There is a long list of things going on in your body to which the various kinds of Vitamin D are essential, even your muscles and muscle tone. In this time of Covid, supplements are going to be important for some people to maintain their immune systems.

@4meAndyou Thank you for the comment, more informative than my doctor who just prescribed vit. D 25.000IU for per week

@Pomegranate I was once told to take it because I had low borderline levels, and I always read up on anything I take.

@Pomegranate Sometimes, even if the doctor doesn't have time to explain things to you, you can call his office and get in depth explanations from the nurse, who usually has a minute.

@4meAndyou He explained it as not getting enough sunlight. But I did expose myself to the Sun regularly. Maybe it wasn't enough, I don't know.🤷‍♀️
That's why I am looking for other causes too.

@Pomegranate We used to have a co-worker at Harvard Pilgrim who had to either go outside, weather permitting, or sitting in front of a special light, for one hour each day.

@4meAndyou mushrooms need to be cooked well to make the nutrients bioavailable.

@cherokeepatti That's good to know! Stews are a good way to get mushrooms, and really good green bean casserole with real cream and porcinis...mmm.
