👉 Vitamin math involves calculating the recommended daily intake (RDI) and adequate intake (AI) levels of vitamins based on various factors such as age, sex, weight, and health status. For instance, the RDI for vitamin C is 90 mg/day for adults men and 75 mg/day for women, while the AI for vitamin D is generally set at 600 IU/day for adults. These values are derived from extensive research and are adjusted for different populations, like pregnant women or individuals with specific health conditions. Understanding these math-based guidelines helps ensure that dietary choices meet nutritional needs, preventing deficiencies or excesses that could lead to health issues.
