Vitamin C: function, importance & role in the body

What is vitamin C?

Vitamin C (ascorbic acid) is a water-soluble and essential vitamin that the human body cannot produce itself.
It must therefore be taken regularly through food or targeted supplements. Vitamin C plays a central role in numerous metabolic processes and is one of the body's most important antioxidants. It supports biological processes that are crucial for energy, cell protection, the immune system and connective tissue structure.

What functions does vitamin C perform in the body?

Vitamin C performs a variety of tasks in various body systems:
  • Contributes to the normal function of the immune system
  • Supports collagen formation for skin, blood vessels, bones and cartilage
  • Protects cells from oxidative stress caused by free radicals
  • Promotes iron absorption from plant foods
  • Contributes to normal energy metabolism
  • Supports the regeneration of other antioxidants, such as vitamin E

Scientific background

The physiological significance of vitamin C was discovered as early as the 18th century, when it was recognized that a deficiency causes scurvy.

Today, the antioxidant effect of vitamin C is considered one of the central mechanisms for cell protection and metabolic stability.
According to the European Food Safety Authority (EFSA), vitamin C contributes to several important bodily functions, including immune defense, collagen formation, nervous system and energy metabolism.

Daily requirements & sources of intake

The German Nutrition Society (DGE) recommends a daily intake of:
  • 95 mg for women
  • 110 mg for men
Natural sources of vitamin C include citrus fruits, berries, peppers, broccoli, spinach, Brussels sprouts, and parsley.

The role of vitamin C in our infusions

Vitamin C is used as a targeted ingredient in our infusions to supply the body directly and efficiently with this important micronutrient.
Intravenous administration enables immediate availability in the bloodstream and thus supplements the daily intake through diet.
This approach supports a conscious supply of nutrients, especially during periods of increased stress or when there is an increased need for vitality.
