Which vitamin is considered the most transient?

Vitamin C is regarded as the most transient vitamin due to its water-soluble nature, which means it dissolves in water and is not stored in the body to any significant extent. Unlike fat-soluble vitamins (such as A, D, and E), which can be stored in fatty tissues for later use, water-soluble vitamins must be consumed regularly in the diet because they are excreted quickly through urine. This characteristic makes Vitamin C particularly susceptible to rapid depletion from the body, especially if dietary intake is insufficient or if there is increased demand due to stress, illness, or other factors. Therefore, consistency in dietary intake is essential to ensure adequate levels of Vitamin C, highlighting its transient status compared to other vitamins that can be stored.
