Bioavailability: Oral absorption peaks at 200–500 mg; excess is excreted via urine, requiring daily intake.
Health Benefits & Mechanisms
1. Antioxidant Defense
Ascorbic acid neutralizes reactive oxygen species (ROS) such as superoxide and hydroxyl radicals, protecting cells, DNA, and lipids from oxidative damage. It regenerates other antioxidants (vitamin E, glutathione), forming a synergistic antioxidant network. Linked to reduced oxidative stress in aging, cardiovascular disease, and inflammation.
2. Collagen Synthesis & Tissue Repair
As a cofactor for prolyl and lysyl hydroxylases, it stabilizes collagen structure—critical for skin elasticity, blood vessel integrity, bone health, and wound healing. Deficiency impairs collagen synthesis, causing scurvy (gum bleeding, joint pain, poor healing).
3. Immune System Enhancement
Boosts neutrophil phagocytosis, supports T/B lymphocyte proliferation, and increases antibody production. May shorten cold duration by 8%–14% in deficient individuals. High-dose IV ascorbic acid shows promise in sepsis and immune modulation research.
4. Iron Absorption & Anemia Prevention
Converts non-heme iron (plant-based) to absorbable ferrous iron, reducing iron deficiency anemia risk—especially critical for vegetarians.
5. Additional Metabolic Roles
-
Neurotransmitter synthesis (serotonin, norepinephrine).
-
Cholesterol metabolism and bile acid formation.
-
Detoxification of heavy metals and toxins.
