The recommended daily dosage of vitamin D for adults fluctuates between 1000 and 2000 IU whereas a dosage correcting deficiencies can be higher and reaches even 4000 IU a day. Cholecalciferol supplementation is important especially in autumn-winter periods when the synthesis of this substance in the skin is considerably impaired.
In the case of suspected vitamin A deficiency, it is suggested to take a dosage which exceeds the recommendations – minimum 10,000 IU a day for no longer than 2 months. Such doses effectively correct deficiencies and show a beneficial effect on the eyesight and condition of the skin.
Both vitamins are fat-soluble compounds. It is thus recommended to to ensure their optimal absorption by taking the vitamins with a meal containing this nutrient.
Vitamin A (retinol) is present in foods of animal origin (fish of the sea, fish, eels, liver, pork and beef, eggs, butter). In the plant products it is present as provitamin A (b-carotene), a powerful antioxidant. The food products containing pro-vitamin A are fruits in yellow and red, including apricots, tomatoes. Necessary in process of building and assimilation of proteins, affects the normal growth of bones and helps the treatment of eye diseases.Iinhibits the excessive action of the thyroid hormone - thyroxine, which simultaneously prevents the deposition of excess vitamin A. Necessary in the sports diet of in the form of food, such as dietary supplements and nutritional supplements.
Vitamin A deficiency causes growth inhibition, flaking and dryness of the skin, impaired night vision (i.e. Night blindness).
Excess of vitamin A leads to calcification of the bones and some soft tissues, and abnormalities in the functioning of glomerulonephritis
Dosage: Specified in IU and it is 5000 IU per day.
Beta-carotene (provitamin A) is a fat-soluble form of vitamin A (retinol). It is a necessary vitamin for the development and acquisition of proteins, necessary to rebuild a bone structure. Irreplaceable in the treatment of eye diseases (prevents decrease of vision and so called night blindness). It strengthens the immune system. It is a strong oxidant. In its natural form it can be found found only in plants (unlike retinol, which is present in foods of animal origin) such as chard, squash, kale, carrots, apricots, tomatoes). Available in the form of supplements and nutrients as an essential component of the sports diet.
Vitamin D belongs to fat soluble vitamins, occurs in three forms: calciferol (vitamin D1) ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), it is formed under the action of sunlight for at least 15 minutes per day. In the absence of sunlight it should be administered in the diet in the form of fish oil (Vitamin A + D3) and fish oils. It is responsible for the absorption of calcium and phosphorus. It is the building substance of bone tissue particularly necessary during pregnancy, childhood, and for athletes. It is a component of dietary supplements and nutrients among competetive athletes. Deficiency of vitamin D causes children growth inhibition, and rickets.
For adults - deficiency causes osteomalacia.
Excess of vitamin D causes headaches, alopecia, nausea, drowsiness, blurred vision, pain in the long bones, the deposition of calcium deposits.
Dosage: 400 IU units during the day.
Lanolin is obtained in the process of cleaning of raw sheep wool from the so-called wool fat, protecting it from getting wet and unbeneficial weather conditions.
Lanolin is commonly used for the production of ointments and creams with lubricating and softening effect, however, it also found application in the production of dietary supplements and more precisely vitamin D3.
In order to obtain vitamin D3 from lanolin, it undergoes cleaning and crystallization and then proper chemical processes, as a result of which 7-dehydrocholesterol is produced - a precursor of vitamin D3, the same which is produced in skin under the influence of UV radiation. 7-dehydrorocholesterol obtained from lanolin is then subjected to the above mentioned radiation, being transformed to vitamin D3.
