A reader named Bob H left the following comment:
I’m on 1000 [IU] a day D3 in the morning. I have not noticed any difference in sleep, but my rosacea has cleared up considerably.
Rosacea is not usually believed to be due to Vitamin D3 deficiency. For example, Wikipedia lists many causes, but not that. Here is another list of causes that does not include Vitamin D3 deficiency. The Vitamin D Council says Vitamin D “cannot be used to prevent or treat rosacea” (but without supporting evidence). On the other hand, when people with rosacea consider the question, they find evidence that D3 helps rosacea. If you have rosacea and have tried D3, please comment or email me about what happened.
I asked Bob H for details.
Tell me about yourself.

When did you start taking 1000 IU/day D3 in the morning? Were you taking D3 before this?
I started taking it about 6-8 weeks ago, in the morning, about 9:00 am 1000 IU – my first time for D3.
Please describe your rosacea before you started 1000/day D3 in the morning. please describe your rosacea now.
I’ve had consistent rosacea for years on my chest. It has not gone away completely, but it’s much better.
Please describe your sleep.
My sleep was good before I started taking D3, and is still good.
Most of the success stories about Vitamin D3 in the morning have involved 4000 IU/day or more. Why did you decide to try 1000 IU/day?
I wanted to start out at a lower dose and build up.
What brand and form of D3 do you take?
1000 IU NatureMade gel.
