The Importance of Regular Vitamin C Intake。(123RF)Vitamin C is water soluble and not stored in significant amounts, regular intake is essential。(123RF)

文章二:The Importance of Regular Vitamin C Intake

Many people often overlook vitamin C, assuming it is abundant in foods, especially since fruits and vegetables are available year-round. As a result, they believe there is little risk of deficiency. While severe vitamin C deficiency (scurvy), along with its associated disabilities and mortality, is indeed rare today, it is important to note that a significant number of people still have low vitamin C levels.

Often, the foods we eat contain sufficient vitamin C, but we may still experience a biochemical deficiency. This can occur if the body, for various reasons, is unable to effectively absorb or utilize the vitamin.

Modern lifestyles also introduce many risk factors for vitamin C deficiency, such as smoking, alcohol use, restrictive diets, selective eating habits, food allergies, Type 1 diabetes, malabsorption, and hemodialysis. Additionally, excessive physical or psychological stress can further increase the risk of vitamin C deficiency.

The human body cannot synthesize vitamin C on its own, so it must be obtained through diet or supplements. Since vitamin C is water soluble and not stored in significant amounts, regular intake is essential. Oral supplements are usually the first choice.
