Which nutrient may vegans commonly be deficient in?

Vegans may commonly be deficient in calcium because this nutrient is predominantly found in dairy products, which are excluded from a vegan diet. Calcium plays a crucial role in maintaining bone health, muscle function, and nerve signaling. While there are plant-based sources of calcium, such as fortified plant milks, tofu, leafy greens, and certain nuts and seeds, the bioavailability of calcium from these sources can be less than that from dairy. Therefore, vegans need to be mindful of their calcium intake and consider fortified foods or supplements to ensure they are meeting their calcium needs.

The other nutrients listed, while important, are less commonly deficient in a well-planned vegan diet. Vitamin C is widely available in fruits and vegetables, carbohydrates are abundant in grains and legumes, and Vitamin A can be obtained from plant sources in the form of beta-carotene found in orange and dark green vegetables.
