What is the best time to take Vitamin D?

Let’s talk about the best time to take vitamin D. Vitamin D is a fat-soluble vitamin. This means that you’re going to have better absorption (30-50% better) if you take vitamin D with fat. 

Some vitamin D supplements contain fat within the supplement itself. But, if you’re going to take vitamin D as a supplement that doesn’t already contain fat, you may want to take it with a meal that contains fat.

If you have a sleep problem, you may want to try taking your vitamin D before bed. Vitamin D may help increase your non-REM sleep. This is the deep delta wave sleep that occurs in the first half of sleep. Vitamin D may also help reduce your cortisol (stress) levels. 

Most people will sleep fine, if not better when they take vitamin D before bed. However, a small percentage of people may find that taking vitamin D before bed wakes them up. These people may need to take vitamin D earlier in the day.
