Should vegans take vitamin D?
Besvaret 27. oktober 2026
Yes. The Danish food authority advises vegans to take 10 µg of vitamin D a day from October to April. In winter the Danish sun is not strong enough for the skin to make vitamin D, and there is hardly any vitamin D in plants.
The winter advice is not only for vegans, though: adults and children aged 4 to 70 are advised to take 5-10 µg a day in the winter months. A systematic review found that vegans got the least vitamin D from food, 1.52 µg a day against 4.17 µg in meat eaters, but meat eaters' intake was also too low. Both authors work for Unilever, which sells fortified foods and supplements. Deficiency was more common in vegans: at most 6 percent of meat eaters against up to 67 percent of vegans in the studies that measured it.
