Suspect this Danish fortification added <500 IU of Vitamin D per day - founder of VitaminDWiki
_*Danish study of childhood diseases vs vitamin D fortification – May 2013 has the following chart
- Danes opposed to Vitamin D fortification, will get more COPD, diabetes, depression, lupus, leg pain, etc – Oct 2015
- Danes have not learned
Finland also fortified and health benefits were found decades later
- Type I Diabetes stopped increasing in Finland after Vitamin D levels were raised – July 2014
- Improved health due to vitamin D fortification in Finland
Fortification works, even if food is cooked, but govts rarely fortifiy with enough
Govts, food producers, and families can fortify:
milk, yogurt, beer, bread, cereals, cooking oil, soups, jams, jellys, honey, snack bars, etc.

Overview Gut and vitamin D has the following summary
- Gut problems result in reduced absorption of Vitamin D, Magnesium, etc.
- Celiac disease has a strong genetic component.
- Most, but not all, people with celiac disease have a gene variant.
- An adequate level vitamin D seems to decrease the probability of getting celiac disease.
- Celiac disease causes poor absorption of nutrients such as vitamin D.
- Bringing the blood level of vitamin D back to normal in patients with celiac disease decreases symptoms.
- The prevalence of celiac disease, not just its diagnosis, has increased 4X in the past 30 years, similar to the increase in Vitamin D deficiency.
- Review in Nov 2013 found that Vitamin D helped
Many intervention clinical trials with vitamin D for Gut problems (101 trials listed as of Sept 2019)

Inflammatory bowel disease (IBD) is a chronic immune-mediated inflammatory disease that can affect the entire digestive tract. Approximately 1% of the Danish population has IBD today. Both the incidence and prevalence of IBD are increasing globally, but the etiology of IBD is still not fully understood. Some, but not all studies find that vitamin D has both protective and therapeutic effects on IBD. To our knowledge, no other study has investigated prenatal exposure to extra vitamin D from either fortified food, diet or supplements in relation to IBD. The aim of this study was to investigate whether a small extra dose of vitamin D from fortification during gestation, was associated with a lower risk of developing IBD in the offspring.
In 1985 mandatory fortification of margarine with vitamin D in Denmark was canceled. To investigate the effect of this policy change we selected all individuals from 2 full year birth cohorts before and after the termination of the mandatory fortification. All individuals were followed for 30 years. By merging data from the Medical Birth Registry with the Danish National Patient Registry, we identified individuals with IBD.
217,249 individuals were included in the analysis. 875 among the exposed and 1102 among the unexposed fulfilled the criteria for being diagnosed with IBD. A lower odds ratio OR = 0.867 (95% CI: 0.792;0.947) for IBD was observed among those who had been exposed to extra vitamin D from fortified margarine during gestation, compared to those who had not been exposed. The analysis was adjusted for sex and season of birth, but results were essentially similar before and after this adjustment.
This study shows, that a small extra dose of vitamin D from fortified margarine during gestation may lower the risk of developing IBD in the offspring, until the age of 30. If these results can be replicated, fortification with vitamin D could be recommended to prevent IBD on a public level.
Prenatal exposure of vitamin D from fortified food could lower the risk of IBD later in life.Vitamin D added to margarine reduced inflammatory bowel disease by 13 percent 30 years later – Nov 2019
