The properties of Vitamin A

Vitamin A is a micronutrient that is crucial for maintaining vision, promoting growth and development, and protecting epithelium and mucus integrity in the body. Vitamin A is known as an anti-inflammation vitamin because of its critical role in enhancing immune function. Vitamin A is involved in the development of the immune system and plays regulatory roles in cellular immune responses and humoral immune processes. Vitamin A has demonstrated a therapeutic effect in the treatment of various infectious diseases.

Vitamin A, and more specifically, retinoic acid, maintain normal skin health by switching on genes and differentiating keratinocytes (immature skin cells) into mature epidermal cells. For the treatment of acne, the most prescribed retinoid drug is 13-cis retinoic acid (isotretinoin). It reduces the size and secretion of the sebaceous glands.

Vitamin A exists in the diet as preformed vitamin A (from animal sources) and as provitamin A carotenoids (sourced from plants). Both sources of vitamin A must be metabolized intracellularly to their active forms (retinal and retinoic acid).

Beta-Carotene

β-carotene is a precursor (inactive form) to vitamin A. Absorption efficiency is estimated to be between 9 and 22%. The absorption and conversion of carotenoids may depend on the form of β-carotene (e.g., cooked vs. raw vegetables, or in a supplement), the intake of fats and oils at the same time, and the current stores of vitamin A and β-carotene in the body.
