The supplement should be swallowed with water, as the vitamin is water soluble. Because of its acidic character, it is recommended to begin the supplementation with the lowest dose proposed by the manufacturer. This results from the fact that the supplement can irritate the intestinal mucosa and induce diarrhoea.
During the vitamin C supplementation it is also recommended to take zinc and iron (in case of any deficiencies). There are numerous studies which confirm benefits resulting from the supplementation of these elements together with the vitamin; in case of zinc we can observe enhanced antioxidant action and reduced vulnerability to infections, and in case of iron – higher bioavailability. Vitamin E enhances its antioxidant action and improves insulin sensitivity.
During high-incidence periods we can increase the vitamin C dose, and during an illness – we can take the loading dose of 5–10 g a day. However, it is worth to divide the dose into a few servings during the day to reduce negative effects of the vitamin.
Vitamin C (ascorbic acid) it is a vitamin soluble in body fluids, can be taken from foods (fruits and vegetables), or as drug derived synthetically. The largest of its resources can be found in broccoli, Brussels sprout, kale, black currant fruit and hawthorn, citrus fruits, tomatoes, Savoy cabbage, potatoes. In fact, intake of vitamin C of the food products does not limit the absorbed quantity. Vitamin C (ascorbic acid) is a potent antioxidant, it is an antitoxic, increasing the immune system due to the elimination of risk of bacterial contamination. Vitamin C prevents rupture of blood vessels, affects the blood cholesterol level. It substantially increases the absorption of iron. Inhibits the growth of cancer cells. Lowers stress levels.
Vitamin C deficiency causes abnormal development of connective tissue, cracking capillaries, abnormal calcification of bone tissue, impaired absorption of iron, scorbutus. With the lack of vitamin C, all kinds of injuries do not heal up properly. Vitamin C deficiency can be caused by smoking; each cigarette is destroying up to 100 mg of vitamin C.
Dosage: The demand is 60-80 mg daily. It does not limit the ability to consume higher doses. Some side effects may occur only with longer taking of synthetic vitamin C.
Ascorbic acid – vitamin C. Its biologically active form is the L-isomer, which negatively rotates the polarised light, so that it is a dextroisomer (laevorotatory vitamin C does not exist). It is a strong antioxidant; it reduces the amounts of free radicals, which reduces oxidative stress, a factor leading to cell apoptosis, which is why it is indicated to be a cause for premature ageing.
It supports the immune system functions and increases body system immunity. It is an essential element of the collagen synthesis path, which is why it positively affects the condition of connective tissue. Hence, it promotes also wound healing and increases the durability of capillary vessel. It is involved in transformations of tyrosine and carnitine as well as of some nutrients, so that it affects metabolism. It can also have an impact on the nervous system functions, as it reduces mental fatigue.
Higher supply of vitamin C is especially recommended in the periods of more intensive body system burden, after infections and in order to accelerate regeneration. The indications for increased supply of the vitamin are also hard physical work or intensive trainings.
Sodium is an important component of the intracellular fluids, and is a regulator of acid-base balance. Along with potassium affects the proper of growth and provides the proper functioning of muscles and nerves. The source of acquisition is table salt (NaCl) and bladderwrack, shellfish, bacon, beef, and of plant beets and carrots. People on salt-free diet should avoid, among others, spicy sauces and smoked meats and sausages.
Sodium deficiency is very rare, at heaving sweating after a long effort (e.g. in the marathon).
Excess sodium increases blood pressure (especially for the elderly), edema and increased thirst. Exceeding the daily dose of 14g a day can cause poisoning.
