Lipovit is an effective complex of the three lipophilic vitamins A, D, and K packed in a soft gel suitable dosage. The fat-soluble vitamins are, as the name implies, soluble in a fat environment. This means that for their absorption in the body must always be present a small amount of fat and should ideally be taken during the meals they contain always a small amount of fat. Only in this way do vitamins bind to fats in the intestine and can therefore be transported from the intestine to the tissues.
The fat-soluble vitamins perform different functions in the human body. The vitamin A contributes to normal iron metabolism, normal immune function and maintenance normal vision and skin, vitamin D contributes to normal functioning of the immune system and the maintenance of healthy bones and muscle function, Vitamin K contributes to normal blood coagulation and to the maintenance of normal bones as it is involved in reactions that regulate the activity of some fundamental proteins in mineralization processes.
Vitamin K, the generic name for a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone, is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement. Vitamin K functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (blood clotting) and bone metabolism, and other diverse physiological functions. Vitamin K might play a role in prevention osteoporosis and coronary heart disease. The effect of vitamin K intakes and status on bone health and osteoporosis has been a focus of scientific research.
Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. Together with calcium, vitamin D also helps protect older adults from osteoporosis.
Fatigue. The fatigue, that is a constant feeling of tiredness and sleepiness, is a problem often overlooked by both doctors and those who perceive it on their skin. These symptoms could also be triggered by vitamin D deficiency and, in this case, also potentially reversible.
Musculoskeletal pain. In patients who report excessive fatigue, possibly associated with musculoskeletal pain and other symptoms, measuring serum vitamin D levels may be useful in the diagnostic process. In numerous studies, low levels of vitamin D were associated with increased muscle pain, highlighting its contribution to normal muscle function.
Depression. Recently it has been shown that vitamin D can have beneficial effects on depression, an increasingly widespread condition that compromises many aspects of life leading to a real disability. Fibromyalgia is a complex problem in which symptoms of anxiety and depression feature prominently. Low levels of vitamin D have been frequently reported in fibromyalgia, but no relationship was demonstrated with anxiety and depression.
Hair loss. Numerous studies have suggested a role of vitamin D on the hair follicle; during the phases of the hair growth cycle, in fact, a greater presence of vitamin D receptors on keratinocytes was observed, a type of cell present in large quantities in our skin. Furthermore, a study conducted on animal models to assess the role of vitamin D in rickets (a skeletal disease caused by a defect in bone formation in the first period of life) found that, by reducing the amount of vitamin D, the hair and hair loss.
The role of this important factor was also put to the test in a study conducted on 8 women with female type hair loss, the most common cause of alopecia in women, characterized by a widespread loss of hair not linked to mechanical causes in frontal, central and parietal area of the scalp. These patients showed significantly lower levels of vitamin D in the blood than women without alopecia: vitamin D levels also decreased with the severity of the disease.
Vitamin A is the name of a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters. Vitamin A is involved in immune function, vision, reproduction, and cellular communication. Several prospective and retrospective observational studies in current and former smokers, as well as in people who have never smoked, found that higher intakes of carotenoids, fruits and vegetables, or both are associated with a lower risk of lung cancer. Age-related macular degeneration (AMD) is a major cause of significant vision loss in older people. AMD’s etiology is usually unknown, but the cumulative effect of oxidative stress is postulated to play a role. If so, supplements containing carotenoids with antioxidant functions, such as beta-carotene, lutein, and zeaxanthin, might be useful for preventing or treating this condition.
