Tag: Iodine in milk

According to a 2023 study published in *Nutrients*, the iodine content in retail cow's milk across the United States varies dramatically, demonstrating a wide range of concentrations for consumers. This inherent variability, however, does not mean the mineral is absent from the finished product.

In the U.S. and U.K., cow's milk is a major dietary source of iodine, with an eight-ounce glass of conventional milk providing a significant portion of the recommended daily intake. Understanding what milk contains iodine is crucial, especially when considering different milk types, such as organic and plant-based options.

According to the National Institutes of Health, dairy products are a significant source of iodine for many people in the United States, providing around 49% of the total estimated daily intake. So, does fresh milk have iodine? Yes, but the amount can vary widely depending on multiple factors.

While milk's iodine content is naturally low, it has become a major dietary source of this vital mineral in many countries due to standard dairy farming practices. This elevated level is a result of intentional feed supplementation and external hygiene procedures.

While milk is widely recognized as a good source of iodine, recent studies show the precise amount can vary dramatically based on location and production factors. Averaging around 85 micrograms per cup in the U.S., the total iodine in 2 cups of milk typically provides a substantial portion of an adult's daily needs. This article delves into the science behind milk's iodine content, the factors that influence it, and why understanding this variability is crucial for managing your dietary intake.

Globally, dairy products, including milk, are a major source of dietary iodine, especially in industrialized nations. Yes, there is iodine in pasteurized milk, but its concentration can vary significantly due to a range of complex factors.

According to a study published in *Thyroid*, milk alternatives contain an average of just 3.1 µg of iodine per 250 mL serving, significantly less than cow's milk. This stark difference raises the question: does all milk have iodine in it, or is the iodine content highly dependent on the source?

Milk and dairy products are major sources of dietary iodine in many countries, often contributing significantly to daily intake. This essential mineral is incorporated into dairy through several key farming and processing practices, not just naturally from the cow's diet. Understanding how this mineral is added sheds light on why iodine concentrations can vary so widely between different products and seasons.
