Alright. I'll bite. What is your justification for taking vitamin D for tiredness AND Sleeplessness?

I don't actually know why it works, but I and my ex both had improved daytime alertness and better sleep when we started taking vitamin d in the winter (and it wasn't an environmental change, I started it one year and had the effect, he started it another year and had the effect).

The trend today in LPT is to post things that worked to help YOU sleep better, as if they are a universal truth.

As I recall, it inhibits melatonin effectiveness.

Vitamin D is a vitamin we usually get from the sun. Studies show that this vitamin supresses melatonin, which is the hormone that helps you sleep (as it's produced usually in response to darkness).

Doctors always recommend taking vitamin D in the morning.
