Individuals with vitamin D deficiency can use nutritional supplements containing vitamin D3 under the supervision of a doctor. When determining the dose of this vitamin supplement, the person’s age, gender, and the level of vitamin D deficiency should be taken into account (3).
The use of vitamin D3 can be provided in the form of tablets or drops on the recommendation of a doctor. Vitamin D3 supplements in tablet form can be taken into the body by swallowing with plenty of water. Those in drip form can be used by dripping into bread or another food recommended by the doctor. Vitamin D3 can raise the body’s energy. Therefore, insomnia can be seen when taken in the evening. It may be advisable to take the supplement in the morning to avoid sleep problems at night.

The dosage and amount of vitamin D3 may vary according to the person. How many days and how many times a day it will be used can be decided by the doctor according to the characteristics of the patient such as vitamin deficiency level, age, diseases, gender. It may be preferable to take it in the morning instead of in the evening during the day. Thus, the effect of vitamin D3 that increases body energy does not interfere with night sleep as it will manifest itself in the early hours
