Micronutrients & recovery
Systematic vitamin D food fortification is an effective and cost-effective public health strategy to improve population-level vitamin D status and reduce deficiency, overcoming the limitations of individual supplementation and sunlight exposure.
If you live in a region with limited sun or eat few fatty fish, look for vitamin D-fortified foods like milk, margarine, or orange juice. This is a safe, passive way to maintain healthy vitamin D levels without needing to remember daily supplements. Check local guidelines for what foods are typically fortified in your country.
Systematic vitamin D food fortification is, however, an effective approach to improve vitamin D status in the general population, and this has already been introduced by countries such as the US, Canada, India, and Finland.
Why this rating
Based on observational data from countries with established fortification (Finland, US, Canada) and meta-analyses of supplementation, though direct long-term RCTs on fortification outcomes are less common than supplementation trials.
