Vitamin A possesses numerous crucial functions that are essential for the continuous physiological processes occurring within the human organism. Its involvement in the process of vision, transcription of genetic information, differentiation of skin cells, as well as support for the immune system, underscores its indispensability for the sustenance of life. This valuable nutrient finds its applications in both the medical and cosmetic fields where it enhances health, well-being, and physical appearance. But when should one consider supplementing with vitamin A?
Vitamin A - where can it be found?
Vitamin A is a generic term for a group of fat-soluble organic substances that are chemically related. It is one of the essential nutrients, but as an exogenous compound, it is not produced in the body and must be supplied with food.
The best, because most concentrated, sources of vitamin A are primarily animal products, such as:
- fatty fish (e.g. salmon, mackerel)
- offal (e.g. liver)
- dairy products (e.g. fatty milk, cheese)
- eggs (especially the yolk)
Vitamin A, although in smaller amounts, can also be found in vegetables and fruits that contain beta carotene. These include:
- sweet potatoes
- carrot
- spinach
- pumpkin
- kale
- apricots
- papaya
- mango
Vitamin A - properties and uses
The presence of vitamin A is indispensable for numerous biochemical processes that occur within the body. This nutrient plays a crucial role in supporting immune function through the effective distribution of T lymphocytes, a type of white blood cell that acts as a shield against infectious agents, and through the stimulation of various other reactions that play a significant part in the immune response.
Vitamin A serves as a potent counteractive measure against free radicals, which are responsible for the onset of several chronic diseases, and is actively involved in the processes of cell growth and differentiation.
Furthermore, vitamin A is pivotal in supporting the skeletal system and is of utmost importance for proper vision. It facilitates the normal development of reproductive cells, making it an essential nutrient for those who wish to conceive. Additionally, it is integral to the health of expectant mothers, developing fetuses, and newborns.
Vitamin A for healthy skin
Vitamin A is an ingredient in many cosmetic products, as it is one of the most effective substances for delaying the skin ageing process. Together with other nutrients, it is also responsible for the condition of hair and nails. When used internally, it can bring a variety of benefits:
- stimulates collagen and elastin production in the dermis of the skin
- regulates sebaceous glands
- accelerates epidermal regeneration process
- prevents the development of skin inflammations and infections
- contributes to the correct decomposition of melanin (reduces discolouration caused by UV rays)
- promotes hair and nail growth
Vitamin A is commonly used during the treatment of dermatological conditions (such as acne and psoriasis).
Vitamin A and its deficiency - symptoms and consequences
Vitamin A ensures the proper functioning of many body functions. Deficiencies most often occur due to an unbalanced diet, liver damage or absorption problems. Common symptoms include:
- night blindness (visual impairment related to the adaptation process of the eye)
- skin changes (such as roughness, dryness, peeling)
- susceptibility to infections
- chronic fatigue
The World Health Organization (WHO) has identified vitamin A deficiency as a significant public health problem in many parts of the world. Long-term deficiency significantly reduces quality of life, but is also associated with serious consequences. Among the most dangerous, experts mention problems with fertility, damage and diseases of the organ of vision (which can even lead to blindness), as well as the malfunction of many organs and body systems.
Vitamin A Drops: A Convenient and Effective Way to Correct Deficiencies
When it comes to dietary supplements, there are various forms available on the market. However, one of the most convenient and practical options is vitamin A drops. This particular form of supplement is highly beneficial in correcting deficiencies and serves as an excellent alternative for individuals who have a dislike for tablets.
Vitamin A drops are a concentrated product that contains a minimal amount of auxiliary substances. The drops primarily consist of the active substance and fat, which facilitates its absorption. The product is very effective due to its fast and efficient assimilation, and it does not cause any significant burden on the stomach, which is particularly important for individuals who require long-term supplementation. The product comes in a small bottle with a pipette, which allows for easy and precise measurement of the dose.
As such, it is evident that avoiding a dangerous vitamin A deficiency does not require a great deal of effort. Simply incorporating a few drops of this supplement into your daily routine can help maintain your overall health, appearance, and well-being.
