Vitamin C (Ascorbic Acid) for Collagen And Connective Tissue

Research suggests that vitamin C plays a recognized role in collagen synthesis, though the single study linked here takes an indirect angle — it investigated whether chemically inhibiting an oxygen-sensing enzyme called prolyl hydroxylase could stimulate collagen production in mouse fibroblast cell cultures, reporting up to a 29-fold increase in collagen type I under laboratory conditions. This in vitro study is notable because prolyl hydroxylase is also a key enzyme involved in vitamin C's own role in collagen assembly, as ascorbic acid acts as a cofactor for this same class of enzymes in biological tissue. The available evidence here is limited to one preclinical cell culture study, which cannot be directly extrapolated to human outcomes, and no randomized controlled trials or clinical studies on vitamin C and collagen were included in this set. Readers interested in the broader human evidence on vitamin C and connective tissue health would benefit from consulting a wider body of clinical literature beyond what is represented in these linked studies.
