> what time of day is best to take this. Some experts say to take in the morning so you will sleep better (my current problem) other experts insist that this be taken at night since Vit D is considered a hormone. Who is correct?

There is only one thing that counts; you need to take it with food, and preferably with your fattiest meal of the day.

Vitamin D won't help you, if you take it in between meals, or if you take it with a low-fat meal.

The exact time of your meal makes little or no difference.-
