Some studies have shown a really limited profit when taken day by day before getting sick, however the profit was small. Overall, the authors concluded that routine supplementation with vitamin C isn’t useful.
Heart disease and stroke

A study Supplementation of greater than 200 mg of vitamin C day by day can lower systolic blood pressure (the highest number within the reading) by about 4 mmHg and diastolic blood pressure (the underside number) by about 2 mmHg. These are very small changes.
These effects are comparable with regular aerobic exercise and will not be clinically meaningful in comparison with treatment. Traditional medicinewhich normally lowers systolic blood pressure by no less than 12 mmHg.
