These groups are recommended to consume an extra 20 micrograms per day via a supplement. These groups include the elderly (70 years and older), because their skin is less able to form vitamin D from sunlight. People with a tan or dark skin color, people who do not often go outside, people who wear a veil and children up to 3 years old are also at increased risk of vitamin D deficiency. For pregnant women, an additional dose of 20 micrograms via a supplement is also recommended.

About two-thirds of the amount of vitamin D you need daily is produced in this way. You get the rest from food. Vitamin D is found exclusively in foods of animal origin. In the Netherlands, vitamin D is added as standard to margarine, low-fat margarine and baking and roasting products. Vitamin D is also added to artificial infant formula in accordance with the applicable EU directive.
