Vitamin C is essential for humans because our body does not produce it (it just metabolizes). Vitamin C can be taken by way of food (food) and by using dietary supplements. Vitamin C overdose is rare because the body constantly regulates it in the blood and tissues. The highest concentration of Vitamin C is retained by our bodies in white blood cells, eyes, adrenal glands, pituitary glands and cerebral cortex. An increase in Vitamin C intake leads to absorption and increased excretion. If we use a dose of 30 to 180 mg daily, our body uses up to 90% of Vitamin C. By increasing the intake to 1000 mg daily, the absorption decreases to 50%.
Due to body exhaustion and decreased immunity, Vitamin C needs are increasing. Clinical data suggest that Vitamin C is useful in the prevention of cancer, cardiovascular disease, vision diseases (old-age macular degeneration and cataracts), colds, better blood pressure control and wound healing.
Vitamin C supplements can be used (daily):
-90 mg for men
-75 mg for women
-120 mg in pregnancy
– 25 mg to 50 mg for children
-2000 mg is the maximum daily dose.
Scurvy is a disease caused by a deficiency of Vitamin C. This disease was once widespread but is rare today. Infants (during the first year of life) use cow’s milk, so the risk of increasing Vitamin C deficiency is increased. Adults treated with anorexia and alcoholism also have an increased Vitamin C deficiency People with Crohn’s disease, ulcerative colitis, celiac disease and type 2 diabetes mellitus are at increased risk for Vitamin C. Dialysis, smoking, breastfeeding and pregnant women are in increased need for Vitamin C.
