Health Canada has mandated an increase in the amount of vitamin D added to milk and margarine products to address the deficiency faced by one in five Canadians. The lack of sunlight exposure, particularly during Canada’s long winters, hampers the body’s natural vitamin D production. Experts emphasize the importance of vitamin D for calcium absorption, which is crucial for bone and teeth strength. Additionally, studies suggest a link between vitamin D deficiency and an increased risk of developing multiple sclerosis.
Besides sunlight, vitamin D can be obtained from dietary sources and supplements like pills or drops. Health Canada, as part of its food fortification strategy, has long required the fortification of milk and other products with vitamin D. Recently, a new regulation was introduced, making it mandatory for milk and margarine producers to significantly increase vitamin D content in their products to meet recommended daily doses.
Under the new regulation effective since December 31, 2025, cow’s milk now contains five micrograms of vitamin D per cup, up from 2.3 micrograms. Similarly, margarine now has about 13 micrograms of vitamin D per 50 grams. This mandatory fortification aims to ensure a more widespread intake of vitamin D among the population.
Health Canada encourages the consumption of vitamin D-rich foods and supplements to meet daily requirements. Yogurt, kefir, and plant-based beverages are permitted to include vitamin D, although it is not mandatory. The regulatory changes are expected to significantly increase the vitamin D intake of Canadians, especially in the winter months when sunlight exposure is limited.
Depending on age, Health Canada recommends varying daily vitamin D allowances. For instance, infants need 10 micrograms, older kids and adults require 15 micrograms, and older adults should aim for 20 micrograms daily. While milk is a good source of vitamin D, other foods like egg yolks and fatty fish also contain this essential nutrient.
Experts stress the effectiveness and affordability of vitamin D supplementation, particularly for individuals on certain medications or with specific medical conditions that may require higher vitamin D intake. While excessive vitamin D intake can have adverse health effects over time, it is rare and typically associated with supplementation rather than dietary sources.
In conclusion, the revised regulations on vitamin D fortification in milk and margarine are set to enhance the overall health of Canadians by addressing widespread deficiencies of this essential nutrient.
