Why Your Blood Needs Vitamin C (Know The Benefits)

Why Your Blood Needs Vitamin C

Vitamin C is a water-soluble vitamin that is necessary for normal growth and development of cells in the blood, as well as the tissues.

Vitamin C helps to form collagen in the bones, cartilage, muscles, and blood vessels, and aids in the absorption of iron.

Although rare, scurvy includes severe consequences, and can cause sudden death.

Patients with scurvy are treated with vitamin C and should be under medical supervision.

Many uses for vitamin C have been proposed, but few have been found to be beneficial in scientific studies.

In particular, research in asthma, cancer, and diabetes remains inconclusive, and no benefits have been found in the prevention of cataracts or heart disease.

  • Repair and maintain bones and teeth
  • Maintain the protein collagen and protects against infection
  • Synthesize neurotransmitters
  • Block some of the damage caused by free radicals by working as an antioxidant along with vitamin E, beta-carotene and many other plant-based nutrients.

The EFSA which provides scientific advice to assist policy makers has confirmed that clear health benefits have been established for the dietary intake of vitamin C in contributing to:

  • The protection of cell constituents from oxidative damage
  • Normal collagen formation and the normal function of bones, teeth, cartilage, gums, skin and blood vessels
  • The increase of non-heme iron absorption
  • A normal function of the immune system
  • The maintenance of the immune system during and after intense physical exercise

Heart Disease

Vitamin C was not shown to lower cholesterol levels, but some evidence suggests that it may help protect arteries against damage by acting as an antioxidant.

High Blood Pressure

Population studies suggest that people who eat foods rich in antioxidants, including vitamin C, have a lower risk of high blood pressure than people who have poorer diets.


In human blood, vitamin C is always in the reduced form. Research has found that the red blood corpuscles are not permeable for ascorbic acid and also to glucose.

Vitamin C oxidizes slowly in blood than in plasma. It’s normal plasma level ranges between 50μM and 100μM according to the diet intake in healthy non-smoker individuals.

Lipid Metabolism

Although Vitamin C is water soluble, it has great effects on blood lipids.

Vitamin C is a factor for protecting lipids in the blood from oxidation.

This vitamin also helps in preventing atherosclerosis and inhibiting the thrombus formation via decreasing the platelet aggregation.

Vitamin C Recommended Intakes

The recommended daily intake (RDI) of vitamin C varies according to age, gender, risk group and criteria applied in individual countries.

In the european union a daily intake of 110mg/day and 95mg/day have been recommended for adult men and women respectively.

In the U.S, 90mg/day and 75 mg/day for men and women respectively have been defined as adequate.

Higher amounts of vitamin C are recommended for pregnant and breast-feeding women.

Emerging evidence suggest that daily intakes of 200mg of vitamin C might be advisable for the adult population.

This can be achieved by means of a diverse diet.
