9. Recommended Daily Allowance (RDA): The recommended daily intake of vitamin C varies based on age, sex, and certain health conditions. For most adults, the RDA is around 75-90mg, but it may increase during pregnancy, breastfeeding, or for individuals with certain medical conditions.

Citrus fruits, kiwi, berries, peppers, broccoli, spinach, and kale are excellent sources of this essential nutrient.

Remember, individual needs may vary, and it’s important to prioritize your overall health and well-being. Consulting with a healthcare professional or registered dietitian can provide personalized guidance based on your specific requirements and help you make informed decisions regarding vitamin C supplementation.
