Many programmers have Vitamin D deficiency. It's a really common issue most people are not aware about. Low Vitamin D has been associated with cardiovascular disease, cognitive impairment, and cancer. It is super easy to treat with a daily pill and you can buy a year's supply off Amazon for $15.

If you have health insurance you can ask your doctor for a free Vitamin D blood test.

+1 on vitamin d deficiency in general.

Now, I'm not a doctor, but my understanding is that most vitamin d can't be absorbed through the intake of pills.

The solution is to expose yourself to 15min sunlight daily, preferably with short sleeves and pants so you have more skin surface to absorb it.

On the plus side, it's cheaper and you get some fresh air!
