Many people take vitamin D in the morning together with other supplements. This is often mainly a matter of habit and convenience, making it easier to remember.
However, some recommendations have suggested that taking vitamin D later in the day might affect sleep.
This is because the vitamin may influence the hormone melatonin, which helps the body regulate its circadian rhythm.
According to a review from Vinmec Healthcare System, there is still no clear research showing that the time of day makes a significant difference.

Food makes a difference
There is greater agreement, however, on how vitamin D should be taken.
The vitamin is fat-soluble, which means the body absorbs it better when it is taken together with food that contains fat.
Studies show that people had higher levels of vitamin D in their blood when they took the supplement with a larger meal.
In another study, vitamin D levels also increased when the vitamin was taken with fatty foods.

Foods such as eggs, nuts, seeds, and full-fat dairy products can therefore help the body absorb the vitamin more effectively.
Many people lack vitamin D
Vitamin D is unique because the body can produce it on its own through sunlight exposure on the skin. Nevertheless, many people still do not get enough.
This is especially true for people who live in areas with limited sunlight. Older adults, individuals with darker skin, and people who are overweight are also at higher risk of deficiency.
Overall, research suggests that the most important factor is not whether vitamin D is taken in the morning or in the evening. The key is to take it regularly and preferably together with a meal.
