Majority of the products had the correct amount of Vitamin D
There is far more variation between individuals to vitamin D due to gut, genes, drugs, etc, etc
Also, there is far more variation of Vitamin D in milk due to fat content

- Vitamin D2 from bread yeast is 4 times less bioaccessible than D2 in milk – April 2016
- Low fat milk provides 2.5 times less vitamin D – May 2016
- Milk fortification of 1000 IU got most children above 20ng of vitamin D – March 2013

• Foods with added vitamin D contained 50-153% of the labelled vitamin D content.
• Dietary supplements contained 8-177% of the labelled vitamin D content.
• Vitamin D content of 3 of 44 products deviated significantly from EU tolerances.
• Trusting label information only may result in invalid estimates of intake.
Note: The amount is too little to help anyway
Due to potential overages to cover losses during shelf life, the actual vitamin D concentration of fortified foods and dietary supplements may deviate from the label. In this pilot study the vitamin D concentrations of fortified foods (n=29; follow-on formula, baby porridge, curd cheese dessert) and dietary supplements (n=15), both specifically intended for infants, were analytically determined. Compared to the declared values, the vitamin D content ranged from 50-153% for fortified foods and from 8-177% for supplements. In general, both instant follow-on formula and oil-based supplements had a measured vitamin D content similar to or higher than the labelled value. Ready-to-eat baby porridge was the only category in which all measured vitamin D concentrations were below the declared value (74-81%). The use of label information for fortified foods and dietary supplements may result in invalid estimations of vitamin D intake distributions of infants; both under- and overestimation may occur.Vitamin D in baby food and supplements varied somewhat from labels – Nov 2016
