Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin C (ascorbic acid) has been investigated for its potential effects on blood pressure and hypertension. While not traditionally associated with hypertension treatment, there is some scientific interest and research on its role. Several observational studies and randomized controlled trials (RCTs) have examined whether vitamin C supplementation can lower blood pressure. The proposed mechanisms include vitamin C’s antioxidant properties, which may enhance endothelial function and nitric oxide availability, leading to vasodilation and potential reductions in blood pressure.

A meta-analysis published in the American Journal of Clinical Nutrition (2012) reviewed 29 clinical trials and found that vitamin C supplementation (average dose: 500 mg/day) modestly reduced systolic blood pressure by about 3.8 mm Hg and diastolic by about 1.5 mm Hg in the short term. However, the authors noted that the evidence was of moderate quality, and the reduction, while statistically significant, was relatively small compared to standard antihypertensive medications. Other reviews and guidelines emphasize that vitamin C should not replace proven therapies for hypertension, but suggest it may have a supportive role, particularly in individuals with low dietary intake.

In summary, there is some scientific validation for the use of vitamin C to modestly lower blood pressure, but the evidence is not strong and does not justify its use as a primary treatment for hypertension. More large-scale, long-term studies are needed to clarify its clinical relevance.
