Vitamin C Levels

Vitamin Metabolism

Vitamin C (ascorbic acid) is a water-soluble antioxidant that supports collagen synthesis, immune function, and iron absorption.

Variants in SLC23A1 and SLC23A2 (vitamin C transporters) have been linked to differences in plasma ascorbate.

This result reflects research-level variation in vitamin C handling and is not a clinical test or a supplement recommendation.

Daily intake from fruits and vegetables, smoking, infections, and overall stress on the body strongly affect real vitamin C status.

DNA Genics reports genotypes based on the 'positive' strand of the human genome reference sequence (build 37/HG19). Other companies may use the opposite strand, so genotypes may need conversion for comparison.
