The Vitamin Intake Calculator estimates your daily vitamin needs and compares your current intake to the general Recommended Dietary Allowances (RDA) for adults based on age and sex. It covers essential vitamins such as A, B complex, C, D, E, and K, showing whether your intake is below, within, or above the healthy range. This helps you identify possible deficiencies or excesses in your diet and adjust accordingly through balanced meals or supplements. Always consult a healthcare professional for personalized nutrition advice, especially if you have medical conditions or are pregnant or breastfeeding.
