Dec 10, 2021 · Due to various risk factors, many COVID-19 and other patients are at high risk to develop low vitamin D status. If possible, it is reasonable to check their serum 25-hydroxy-vitamin D levels, and only after that, an appropriate dose of vitamin D supplements should be suggested.

I used to recommend a supplement of vitamin D 1000 IU/day. This was the dose recommended by the American Geriatrics Society(AGS), starting in 2013. (As of 2022, they have not yet changed their recommendation.) However, I’ve recently decided to suggest a vitamin D dose of 800 IU/day, in part because of the results of this 2021 study. I do this becau...
Which type of Vitamin D should I take?
Most supplements contain vitamin D3, also known as cholecalciferol. Studies suggest that this increases blood levels a little better than vitamin D2 (ergocalciferol). Both these versions of vitamin D require processing by the liver and kidneys. People with liver or kidney disease may need to get a special type of supplement from their doctors. Although Vitamin D supplements are usually taken daily, they also come in higher doses, which may be prescribed for weekly or even monthly dosing. (The...
Do I need to have my vitamin D blood level checked?
Probably not. The AGS consensus statementsays that testing vitamin D levels should be unnecessary in most older adults, unless some particular symptom or disease warrants it. (I’m not aware of any research published in the past few years that makes a case for routinely testing vitamin D levels of older adults.) The idea is that if people take a daily vitamin D supplement as recommended above, they’ll be highly unlikely to have a vitamin D level that is too low or too high. On the other hand,...
What should one’s vitamin D level be?
This question has been hotly, hotly debated. At this time, it depends on whom you ask. The Institute of Medicine believes a blood level of 20-40 ng/mL should be adequate. The Endocrine Society, the American Geriatrics Society, and some other expert groups recommend a level of at least 30 ng/mL. As noted above, the party line — which I consider reasonable — is that most people don’t need their vitamin D level checked. In the absence of certain health problems, a low vitamin D level is unlikely...

Average daily vitamin D intake in the population at large and current dietary reference intake values are often inadequate to maintain optimal vitamin D levels. Clinicians may recommend supplementation but be unsure how to choose the op- timal dose and type of vitamin D and how to use testing to monitor therapy.
