What is the recommended dietary allowance (RDA) for vitamin C in adult men?

The recommended dietary allowance (RDA) for vitamin C in adult men is 90 mg per day. This value was established to meet the needs of most adult men to prevent deficiency and support overall health. Vitamin C plays a vital role in various physiological functions, including collagen synthesis, antioxidant protection, immune function, and the absorption of iron from plant-based foods. Adequate intake is essential for maintaining healthy skin, blood vessels, and overall tissue integrity.

Selecting this value as the RDA ensures that men receive sufficient levels of vitamin C, which is particularly important because the body does not store large amounts of this vitamin, and it is vital to consume it regularly through diet. Common sources of vitamin C include fruits and vegetables, such as oranges, strawberries, bell peppers, and broccoli, making it accessible for those who follow a varied diet.
