Synopsis

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

Vitamin C (ascorbic acid) is scientifically recognized for its role in maintaining the health of the circulatory system, particularly through its antioxidant properties and its contribution to collagen synthesis. Collagen is an essential structural protein in blood vessels, helping to maintain their integrity and elasticity. Deficiency in vitamin C (as seen in scurvy) leads to weakened blood vessels, bleeding, and impaired wound healing, clearly demonstrating its importance for vascular health.

Additionally, vitamin C acts as an antioxidant, reducing oxidative stress that can damage the endothelial lining of blood vessels and contribute to atherosclerosis. Some clinical studies suggest that higher vitamin C intake is associated with improved endothelial function and lower blood pressure, both of which support overall cardiovascular health. However, large-scale randomized controlled trials have not consistently demonstrated that vitamin C supplementation reduces major cardiovascular events like heart attacks or strokes in the general population. Most benefits appear to be in populations with low baseline vitamin C status or in the prevention of deficiency-related vascular problems.

In summary, there is scientific validation for vitamin C’s role in supporting the circulatory system, particularly in maintaining blood vessel health and integrity. However, evidence for its use in preventing or treating cardiovascular disease in well-nourished individuals is moderate, not strong, hence a rating of 3.
