Application

    1.Visual Function: Essential for maintaining dark adaptation by participating in rhodopsin synthesis (11-cis retinal + opsin). Deficiency prolongs dark adaptation time.
    2.Epithelial Integrity: Stabilizes epithelial cell membranes, regulates glycoprotein synthesis, and prevents keratinization. Critical for ocular, respiratory, and mucosal health.
    3.Nuclear Autacoid Activity: Acts via retinoic acid receptors (RAR/RXR) to regulate gene expression, influencing cell differentiation, apoptosis, and developmental processes.
    4.Immune Support: Enhances cellular immunity, antibody production, and natural killer cell activity. Modulates cytokine release and lymphocyte function.
    5.Growth & Reproduction: Vital for embryonic development, bone formation, and reproductive organ function. Deficiency impairs spermatogenesis and skeletal growth.
    6.Bone Metabolism Interaction: Antagonizes vitamin D activity. Both deficiency and excess disrupt bone mineralization and remodeling.
    7.Antiproliferative Effects: Chemopreventive, induces apoptosis, and promotes terminal differentiation in neoplasms cells.
    8.Hemoglobin Synthesis: Enhances iron absorption, stimulates erythropoiesis, and regulates hematopoietic processes across developmental stages.
    Foods rich in vitamin A:

a. Animal Livers: Sheep liver, beef liver, chicken liver, pork liver, etc.;
b. Eggs, whole milk;
c. Vegetables: Cauliflower, tomatoes, corn, cabbage, etc.;
d. Fruits: Mangoes, cantaloupe, pears, apples, loquats, grapefruit, papaya, nectarines, etc..
