Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin C (ascorbic acid) is scientifically validated as important for the "Blood" body system, particularly in relation to iron absorption and the maintenance of healthy blood vessels. Multiple studies have demonstrated that vitamin C enhances non-heme iron absorption from plant-based foods, which can help prevent iron-deficiency anemia—a common blood disorder. The mechanism involves vitamin C reducing ferric iron (Fe3+) to the more absorbable ferrous form (Fe2+), facilitating efficient uptake in the intestine. Additionally, vitamin C is essential for the biosynthesis of collagen, a structural protein in blood vessel walls, supporting vascular integrity and reducing the risk of bleeding disorders such as scurvy, which is characterized by fragile capillaries and bleeding gums. While vitamin C is not directly involved in erythropoiesis (the production of red blood cells), its role in iron metabolism indirectly supports healthy blood function. However, clinical trials on vitamin C supplementation for the prevention or treatment of anemia have produced mixed results, with clear benefits mostly in populations with low dietary iron or vitamin C intake. There is robust evidence for its necessity in maintaining vascular health, but less so for broader claims about blood health beyond these specific mechanisms. Thus, the use of vitamin C for supporting the blood system is grounded in scientific evidence, though the strength of evidence varies by specific application.
