Abstract:

This group of vitamins consists of vitamin D2 and vitamin D3, which are synthesized in the body of some invertebrates and plants, but also in the human body. Ultraviolet rays cause vitamin D to integrate under the skin. The vitamin is transported via specific proteins to all parts of the body, where it performs numerous roles. The low level of vitamin D in blood is a current public health problem. Vitamin D deficiency is especially pronounced among the elderly and obese. Currently, vitamin D deficiency is associated with an increase in bone and cardiovascular diseases, diabetes, malignant, aut

Abstract:

Vitamins are generally essential; they are mandatory compounds that are not produced in the body and must be taken through food. These compounds, which play a role in enzyme reactions as coenzymes, are indispensable for the human organism. Among them, vitamin D, which is of great importance, can be made in the body differently from others. Vitamin D is a fat-soluble vitamin. Since its chemical structure is similar to steroid hormones and is synthesized in tissue and released into the circulatory system due act on the target tissue, it can also be classified as a hormone.

Despite its historical name, vitamin D is not a vitamin at all but a hormone that, when activated, is a metabolically active steroid fat-soluble hormone that acts on cellular receptors. Vitamin D hormone is synthesized endogenously and then metabolized in the body, provi-ding that there are the necessary precursors and some factors — the effects of ultraviolet light on the skin. At the same time, vitamins themselves are nutrients, co-factors of biochemical reactions that are not synthesized in the body and cannot interact with receptors, consumed with food, so the hormone D is not a vitamin.

Vitamin D, unlike other vitamins, is a fat-soluble steroid hormone rather than a cofactor for enzymatic reactions. The main role of vitamin D is to regulate bone metabolism and calcium-phosphate homeostasis. Lack of vitamin D causes osteomalacia and osteoporosis in adults, and rickets in children. Vitamin D receptor (VDR) expression levels throughout the body are quite variable. Interestingly, VDRs are found in pituitary tissue. Unsurprisingly, vitamin D levels might impact hypophyseal production or activity of hormones such as growth hormone, gonadotropins (follicle-stimulating hormone, lutei

Abstract:

Obesity can be associated with several diseases, signs, and symptoms. Among them, there is nutrient deficiency, especially vitamin D, which regulates calcium and phosphate and helps in bone remodeling. Vitamin D deficiency is related directly to the inadequate intake of foods rich in vitamins, less exposure to the sun and, mainly, to the sequestration of fat-soluble vitamins by the adipose tissue, making it even more difficult for the body to absorb them. Among these complications is the worsening of vitamin deficiency, with a focus on vitamin D, which is already present before the patient und

Vitamin D is also known among the public as the Sunshine vitamin, as it is produced internally within the human body when exposed to sunlight and it is well known that the big majority of United Arab Emirates (UAE) population suffer from its deficiency.They are usually not found inside the body and therefore must be eaten from food or taken by supplements.

Abstract:

Vitamins are essential dietary items because of their functions as enzyme cofactors and catalysts in the body. Vitamin deficiency can significantly impact the skin, leading to a variety of dermatological problems, such as dryness, premature aging, hyperpigmentation, palmoplantar keratoderma, and even nail disorders. Alcoholism, rigid diets, inadequate parental nourishment, and intestinal absorption issues may all be factors in vitamin deficits. The most commonly deficient vitamins in relation to skin health are vitamin A, biotin, vitamin C, and vitamin D. Vitamin A helps to maintain the skin's

However, choosing the most efficient route and form of supplementation requires insight into how different vitamin D metabolites are transported in the body of cattle.
