What is Vitamin C?

Vitamin C (L-ascorbic acid) is a water-soluble vitamin that the body cannot produce or store, making regular dietary intake essential. It functions as a vital cofactor for numerous enzymatic reactions, most notably collagen synthesis, and serves as one of the body's most important water-soluble antioxidants. Every cell in the body depends on vitamin C for its basic metabolic processes, from energy production to tissue maintenance.

Among all water-soluble vitamins, vitamin C has the broadest reach across physiological systems. It supports the structural integrity of blood vessels, skin, bones, and connective tissue through collagen formation, enhances immune cell function, facilitates iron absorption from plant-based foods, and helps regenerate other antioxidants such as vitamin E. This versatility makes vitamin C one of the most comprehensively studied nutrients in the world.

EFSA-approved health benefits

The European Food Safety Authority (EFSA) has confirmed that vitamin C:

  • contributes to normal collagen formation for the normal function of skin, bones, cartilage, gums and teeth
  • contributes to the normal function of the immune system
  • contributes to normal energy-yielding metabolism
  • contributes to the protection of cells from oxidative stress
  • contributes to the reduction of tiredness and fatigue
  • contributes to the normal functioning of the nervous system
  • increases iron absorption
  • contributes to the regeneration of the reduced form of vitamin E

Why we use Vitamin C in Nutri-Leaf formulas

Our Vitamin C 1000mg formula contains just two ingredients: 1000mg of L-ascorbic acid and the plant-based HPMC capsule. No fillers, no flow agents, no preservatives. This minimal formulation reflects our commitment to transparent nutrition: you should know exactly what you are taking.
