Vitamin C 500Mg Chewable Tabs 300S (Orange)

Overview & Mechanism of Action

• Vitamin C Chewable Tablets ($300\text{-tablet}$ economy bottle providing Ascorbic Acid $500\text{mg}$ per tablet in a tangy orange flavor) serves as a vital water-soluble antioxidant and essential enzymatic cofactor across systemic metabolic pathways:
• Antioxidant & Free Radical Scavenging: Donates electrons to rapidly neutralize reactive oxygen species ($\text{ROS}$) and oxygen free radicals generated by environmental pollutants, cellular metabolism, and physical stress, protecting cell membranes and cellular $\text{DNA}$ from oxidative injury.
• Collagen Hydroxylation & Structural Integrity: Acts as a required co-substrate for prolyl hydroxylase and lysyl hydroxylase, driving the post-translational hydroxylation of proline and lysine residues. This stabilizes the triple-helix collagen structure critical for vascular elasticity, dermal healing, cartilage, and bone matrix formation.
• Immune Cell Modulation & Non-Heme Iron Reduction: Enhances neutrophil chemotaxis, phagocytosis, and lymphocyte proliferation during immune challenges. Simultaneously reduces dietary non-heme ferric iron ($\text{Fe}^{3+}$) to the more absorbable ferrous state ($\text{Fe}^{2+}$) within the gastrointestinal tract.
