“Humans do not have metabolic pathways leading to the synthesis of this vitamin, therefore it must be supplied on an ongoing basis with food.”
vitamin c for firm, wrinkle-free skin
“Scientists suggest that the decline in the efficiency of collagen production can, however, be stopped. One of the most effective methods of stimulating the production of this protein is to provide the appropriate amount of vitamin C. According to research published in the medical journal “International Journal of Cosmetic Science”, the long-term effect of vitamin C on human connective tissue cells can increase the synthesis of collagen up to eight times.” “In the process of creating the structure of collagen fibers, the presence of hydroxyl groups of proline and lysine plays an essential role, enabling the correct folding and connection of the chains. Therefore, any disruption of hydroxylation leads to the formation of collagen with an inappropriate structure that does not meet its biological and mechanical properties. The reason for this may be a deficiency of vitamin C as an essential cofactor of hydroxylating enzymes, which causes disruptions in collagen biosynthesis. The result is a loss of skin firmness and elasticity, i.e. the presence of wrinkles and fragility of capillaries, which break easily, causing bloody subcutaneous micro-hemorrhages.”
Vitamin C and immunity at the highest level
“…one of the mechanisms of vitamin C in alleviating cold symptoms is to protect cells (especially phagocytes) against oxidative stress, significantly increased during infections due to the production of endogenous radicals.” “…the supply of vitamin C significantly reduced the incidence of colds (by approximately 40%!) in people exposed to physical exercise or cold… Studies were also carried out to assess the impact of vitamin C administration on the duration of colds. It was proven that additional supplementation with the vitamin was associated with an 8% and 14% reduction in the duration of the disease, in adults and children, respectively.”
Vitamin C and the cardiovascular system
“Vitamin C is the most well-known antioxidant. Thanks to its antioxidant properties, this vitamin plays a protective role in heart and blood vessel diseases.” “Vitamin C can be used in the prevention of atherosclerosis due to its protective effect on the vascular endothelium and prevention of oxidation of the low-density lipoprotein (LDL) fraction.” “PF Jacques et al halved the incidence of elevated blood pressure by increasing vitamin C intake to 240 mg daily.”
Vitamin C and osteoporosis
“Researchers from Mount Sinai School of Medicine (USA) conducted an experiment that showed that vitamin C can prevent osteoporosis in mice. This is due to the effect of vitamin C on the activity of osteoblasts (bone-forming cells), contributing to the maturation of immature bone cells and ensuring appropriate mineralization.”
Vitamin C for good eyesight
“Vitamin C is used to treat superficial corneal lesions and senile lens opacity.”
Vitamin C accelerates wound healing
“Vitamin C is used in difficult healing of wounds and bedsores, skin discoloration, hemorrhagic conditions and capillary diseases. Because it affects the sealing of vessels and accelerates blood clotting, its beneficial effects in various bleeding situations become understandable.”
Vitamin C increases the absorption of calcium and iron
“Vitamin C also supports the absorption of calcium from the digestive tract and stimulates the synthesis of prostaglandins (hormones that are involved in many physiological processes).” “Stimulation of the absorption of non-heme iron from food has also been demonstrated following the administration of vitamin C.”
What else is worth using vitamin C for:
“Indications for the use of vitamin C also include: tooth decay, periodontal disease and allergic diseases.” “Vitamin C also lowers blood glucose levels in hyperglycemic states and lowers fasting blood sugar levels in diabetics.” “Four-week supplementation of men aged 20-35 with 200 mg of vitamin C increased sperm activity by 15%, and in those supplemented with 1 it by 40%.” “Vitamin C helps in the proper functioning of the nervous system, in maintaining proper psychological functions and contributes to reducing the feeling of fatigue and weariness.”
People particularly vulnerable to vitamin C deficiency
“Increased consumption of vitamin C occurs during heavy physical exercise, injuries, excessive exposure to UV rays, in long-term stressful situations and in old age. Increased consumption of vitamin C is observed in pregnant and lactating women.” “Increased demand for vitamin C occurs in people with hypertension, smokers, alcoholics, diabetics, pregnant and breastfeeding women, as well as in people taking certain medications and under constant stress. It increases with heavy, long-term physical exercise, vomiting, lack of appetite and intestinal dysfunction.”
How does food processing destroy valuable vitamin C?!
“Technological processes using high temperatures, e.g. convection drying, reheating food, but also too quick defrosting, result in accelerated decomposition of vitamin C. Vitamin C losses during culinary processing can range from ͖20% when preparing salads, up to ͙50% when cooking vegetables. Due to the very good solubility of vitamin C in water, when cooking plant raw materials, this vitamin is washed out and transferred to the broth.” “Also, long storage of vegetables, fruits and preserves, especially in unsuitable conditions, leads to rapid loss of this vitamin.”
