The Dairy Dilemma: A Closer Look at Vitamin D Fortification
For years, vitamin D has been touted as a miracle nutrient, essential for bone health and immune function. But what happens when this fat-soluble vitamin is added to our daily dairy? A recent study delves into this question, examining the effects of vitamin D-fortified dairy products on liver function in adults with abdominal obesity.

The effects of low-fat dairy products fortified with 1500 IU vitamin D3 on serum liver function biomarkers in adults with abdominal obesity: a randomized controlled trial by Payam Sharifan et al. in 2023.
The Source Article's Abstract
Vitamin D deficiency has been reported to affect liver function biomarkers. This study was aimed to investigate the effect of consuming vitamin D fortified low-fat dairy products on liver function tests in adults with abdominal obesity.
This total blinded randomized controlled trial was undertaken on otherwise healthy abdominally obese adults living in Mashhad, Iran. Milk and yogurt were fortified with 1500 IU vitamin D nano-capsules. Participants were randomized to receive fortified milk, plain milk, fortified yogurt, and plain yogurt for 10 weeks. Blood samples were taken at baseline and at the end of the study to assess serum levels of vitamin D, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase (ALP), and Gamma glutamyl transferase.

(2023). The effects of low-fat dairy products fortified with 1500 IU vitamin D3 on serum liver function biomarkers in adults with abdominal obesity: a randomized controlled trial. Journal of Health, Population and Nutrition, 42(102). 10.1186/s41043-023-00401-6
The study is a randomized controlled trial conducted on abdominally obese adults in Mashhad, Iran. Participants were divided into groups receiving either fortified or plain milk and yogurt for a span of 10 weeks. Blood samples were collected at the beginning and end of the trial to assess various liver function markers.
It’s worth noting that the dairy products were fortified with 1500 IU of vitamin D nano-capsules, making this study particularly relevant for understanding the impact of high-dose vitamin D fortification.
Implications for Liver Health
While the full results are not available, the study aims to shed light on whether vitamin D fortification in dairy products has a beneficial or detrimental effect on liver function. This is crucial given the rising rates of liver diseases, particularly non-alcoholic fatty liver disease (NAFLD), associated with obesity.
Moreover, vitamin D deficiency is a common issue worldwide, and fortifying food staples like dairy products could be a double-edged sword. It could either help in preventing liver diseases or exacerbate existing conditions.
