The recommended daily allowance (RDA) of Vitamin C for adult women is 75 mg. This recommendation is based on the intake levels necessary to maintain optimal health, supporting functions such as the immune system and skin health. Vitamin C is an essential nutrient that acts as an antioxidant and plays a critical role in collagen synthesis, which is vital for maintaining healthy skin, blood vessels, and connective tissues. The RDA is set to ensure that most healthy individuals have sufficient vitamin C to support these functions without an increased risk of deficiency. Thus, the value of 75 mg reflects the current understanding of how much Vitamin C is needed to meet the nutritional requirements for adult women.
