/ 5.0
Standardized Form
Ascorbic Acid, Sodium Ascorbate, or Liposomal Vitamin C

While renowned for immune support, Vitamin C (Ascorbic Acid) is physiologically indispensable for tissue repair and collagen synthesis. It acts as an obligate cofactor for two key enzymes—prolyl hydroxylase and lysyl hydroxylase. These enzymes are responsible for stabilizing the collagen molecule into its strong, triple-helix structure. Without adequate Vitamin C, the body cannot form structurally sound collagen, regardless of how much collagen protein is consumed.

Clinical Summary

Universally recognized as critical for connective tissue health, wound healing, and neutralizing oxidative stress (free radicals) that degrade existing collagen.

Dosage Guidelines

65mg to 90mg for baseline health; often dosed between 500mg and 1,000mg in therapeutic or collagen-support protocols.

Safety & Side Effects

High doses (above 2,000mg) can cause gastrointestinal distress, osmotic diarrhea, and increase the risk of kidney stones in susceptible individuals.

Known Interactions

Can increase the absorption of non-heme iron; may interfere with the efficacy of certain chemotherapy drugs at megadoses.
