In general, fortified beverages provide an easy and effective way to compensate for vitamin D deficiency, especially when choosing the right types and incorporating them into a balanced diet. Fortified orange juice is a well-known source of vitamin D, but it is not the highest. Other beverages offer greater amounts and help meet daily needs better. A report on the Verywell Health website indicates that one cup of fortified orange juice contains about 100 International Units (IU) of vitamin D, while other drinks provide higher amounts. Data shows that fortified milk leads the way, offering about 117 IU per cup. It is a popular choice that also supports bone health thanks to its calcium content. Plant-based milk types, such as soy or almond, can provide similar or slightly higher amounts, reaching around 119 IU in some varieties, with the added benefit of being suitable for plant-based diets. Kefir, especially if fortified, can provide over 100 IU per serving, along with benefits for digestive health. Some ready-to-drink protein shakes also contain high levels of vitamin D, which can reach up to 332 IU per serving, though this varies greatly by brand. Mushroom broth also stands out as a potential plant-based source, especially when using mushrooms exposed to ultraviolet light, as they can contain considerable amounts of the vitamin, although the level depends on the preparation method. Recommendations suggest that adults need about 600 IU of vitamin D daily, making diversifying fortified beverage sources a practical way to reach this goal, especially for those who do not get enough sun exposure. However, relying solely on these beverages may not be sufficient, as the amounts vary by product, and vitamin D absorption is affected by other factors like the overall diet.
