To ensure adequate vitamin C intake, incorporate a variety of fruits and vegetables rich in this essential nutrient into your diet. Citrus fruits like oranges, lemons, and grapefruits are well-known sources. However, berries, kiwi, bell peppers, broccoli, and spinach are also excellent choices. Aim for at least five servings of fruits and vegetables daily to meet your nutritional needs. If you find it challenging to obtain enough through diet alone, consider supplementing with vitamin C capsules after consulting with a healthcare professional. Regularly including these foods not only supports immune function but also contributes to overall health.
