Khaberni - Some people turn to dietary supplements as a way to support heart health, with Vitamin C emerging as one of the popular options. But the important question is: Does taking it daily actually lower blood pressure? According to a report on Verywell Health, the effect exists but is limited and not scientifically decisive.
A recent scientific review that included 20 studies with about 890 participants, showed that taking a daily dose of approximately 757 mg of Vitamin C for six weeks led to an average decrease in systolic blood pressure by about 3 mm Hg. Other analyses showed a slightly greater decrease up to 5 mm Hg when taking doses of 500 mg or more daily, especially in older adults or those with high blood pressure.
The results suggest that Vitamin C may contribute to a slight reduction in blood pressure, but it is not a treatment in itself. The recorded numbers, despite their importance, remain limited compared to the effects of medications or lifestyle changes.
Blood pressure is measured by two numbers: systolic, which is the pressure when the heart pumps blood, and diastolic, which is the pressure when the heart is at rest. The normal rate is about 120/80 mm Hg, while hypertension starts at levels above 130/80.
Why might Vitamin C help?
Vitamin C is linked to antioxidant properties, which may help improve blood vessel function and reduce inflammation. However, this mechanism is still under study and has not been conclusively proven as a direct cause for reducing pressure.
Experts emphasize that high blood pressure is a serious medical condition that can increase the risk of heart disease, stroke, and organ damage. Therefore, reliance solely on supplements is not recommended, and a proper diagnosis and follow-up with a physician are necessary.
Also, the body does not store Vitamin C, which means it is necessary to obtain it daily from food or supplements, with a recommended dose ranging between 90 and 120 mg for adults.
Besides supplements, the most impactful factors remain, such as reducing salt intake, regular physical activity, maintaining a healthy weight, and reducing stress.
Therefore, taking Vitamin C daily may help lower blood pressure slightly, but it is not a sufficient solution on its own. The relationship here is supportive and not therapeutic, and the basis remains in lifestyle and regular medical follow-up.
