At least 500 mg per day for an average of eight weeks, can have positive effects.
High blood pressure or hypertension is better known as quite silent killer, a disease that did not show symptoms but can lead to critical fatal attack.
This condition is usually associated with cardiovascular diseases such as heart disease and stroke. Researchers at Johns Hopkins have good news for those people with hypertension. From the results of his research found that consumption of high doses of vitamin C can help reduce the problem of hypertension in adults.
The study, published in the latest issue of American Journal of Clinical Nutrition, found that regular consumption of vitamin C can cause a moderate decrease a person’s blood pressure.
As quoted by page Yahoonews, Sunday, April 22, 2012, the study referred to as “review”, which previous research to analyze the pattern and observations. In this case, the scientists looked at data from 29 previous clinical trials involving more than 1,400 people to reach their conclusions, according to the Baltimore Sun.
What was found from this study?
Preliminary conclusions indicate that consuming large amounts of vitamin C, at least 500 milligrams per day for an average of eight weeks, can have positive effects, especially for someone who is suffering from hypertension. This amount is equivalent to about five times the current daily recommendations.
Vitamin C may be able to preserve or protect the level of nitric oxide in the body. Nitric oxide is a special function to help maintain healthy blood pressure.
Previous research about the health benefits of vitamin C have focused on the possible role of nutrition as a diuretic. Thus, it can more efficiently help the kidneys to rid the body of excess sodium and water, which has the effect of lowering blood pressure by relaxing blood vessels.
Even so, Johns Hopkins researchers have recommended this research results for many people. Dr. Edgar R. Miller III, one of the principal investigator in the study also said in the official press release, that it is too early to recommend a specific action. Further studies are needed to determine the exact impact of vitamin C on blood pressure.
Preliminary studies by the experts are also not designed to prove whether there is a long-term benefits from the consumption of high doses of vitamin C. In particular, there is no evidence that taking large amounts of vitamin C will reduce a person’s risk of heart attack or degrade a person’s risk of stroke
