D-Cap (100mg) 20 Capsules

Vitamin A capsules primarily exert their effects through the active ingredient retinol, a form of vitamin A. Retinol is a crucial nutrient that plays a significant role in various physiological processes, particularly in maintaining healthy vision and promoting proper growth and development. The mechanism of action involves the conversion of retinol into retinal and then into retinoic acid within the body. Retinoic acid acts as a ligand for nuclear receptors known as retinoic acid receptors (RARs) and retinoid X receptors (RXRs). These receptors, upon binding with retinoic acid, form heterodimers that regulate gene expression by activating or repressing specific target genes. This process influences cellular differentiation, proliferation, and apoptosis, particularly in tissues such as the retina, skin, and mucous membranes. Vitamin A's actions contribute to the maintenance of epithelial tissues, support immune function, and play a vital role in the visual cycle, where it is essential for the conversion of light into neural signals in the retina.
