Sample Case Study on Vitamin C with anti-hypertensive therapy

Vitamin C


The study under consideration examined the impact of vitamin C on hypertension. An observational study was performed on 70 out-patients between 35 and 60 years with the hypertensive disorder from the general medicine department of Princess Esra Hospital. Data was gathered from concealed important medical files of 70 patients and patient interviews. The participants were only offered anti-hypertensive therapy for the first 45 days, and their blood pressure was noted. The same participants were prescribed with both hypertensive therapy and vitamin C 500mg/day after 45 days. Their blood pressure was examined and documented. A comparison of variations in blood pressure was conducted. The results indicated a substantial reduction in systolic blood pressure and diastolic blood pressure in participants at the end of 45 days of Vitamin C intake. The research revealed the modest effect of vitamin C in reducing blood pressure when taken with anti-hypertensive medications.

Critique of the Study

The study combined vitamin C with anti-hypertensive therapy, which assists in lowering blood pressure, strengthening immunity, and retaining homeostasis. However, there was no a control group and the sample size was small. Limitations associated with patients were the lack of knowledge regarding the medical condition, poor drug compliance, and inconsistent follow-ups. The information from the study can help medical practitioners to understand that continuous vitamin C supplementation can be a cheaper secondary therapy for high blood pressure patients. The results of the study can also assist physicians in managing hypertension, which can result in several chronic diseases if not properly managed.
