Increased blood pressure is a component of prediabetes metabolic syndrome, so naturally I took an interest to a recent study showing that increased vitamin C intake has shown some positive correlation with good blood pressure.
A new meta-analysis suggests that over the short-term vitamin C supplementation may reduce blood pressure, with even more benefit for people that have high blood pressure.
A recent meta-analysis that looked at the relationship between vitamin C intake and blood pressure showed that Vitamin C supplementation was associated with reductions in systolic and diastolic blood pressure of 3.84 and 1.48 mm Hg, according to findings published by Johns Hopkins researchers in the American Journal of Clinical Nutrition (April 2010). Despite the low point reductions, these blood pressure reductions were deemed significant.
Also, when the data was limited to people with high blood pressure (hypertension), supplements of vitamin C were associated with systolic and diastolic blood pressure reductions that were a tad better at 4.85 and 1.67 mm Hg.
This meta-analysis is said to be the first to evaluate the effects of vitamin C on blood pressure. Meta-analyses can provide good information, but they are by no means flawless. Not to mention that nutrition and metabolism research can make quantum mechanics research look “all black and white.”
As with a lot of nutrition and diet supplement meta-analyses, the data available was primarily from small, short-term trials and there was a lot of variation in the studies included in the analysis: Twenty-nine clinical trials, with a median dose of vitamin C of 500 milligrams per day, median trial duration of eight weeks, and trial sizes from 10-120 people.
High blood pressure (hypertension) is defined as having a systolic and diastolic blood pressure greater than 140 and 90 mmHg, respectively. Many people are more aware of their blood pressure these days as blood pressure machines are in supermarkets and pharmacies. More doctors are routinely taking blood pressures in the office because of the electronic health record guidelines set up by the government to promote meaningful use.
High blood pressure is of particular interest at Nutrientology since it is a component of metabolic syndrome, also known as syndrome x or prediabetes. Adequate vitamin C intake has a number of benefits. Obtain sufficient vitamin C in your diet. Citrus is probably the most well-known source, however many green leafy vegetables actually have higher concentrations of vitamin C than citrus. Green peppers in particular have a high vitamin C content—It is amazing how much of our general food “knowledge” is the result of highly coordinated marketing campaigns.
If your diet does not contain sufficient Vitamin C or other necessary nutrients for peak health, consider a Vitamin C supplement or a good vitamin C containing MultiVitamin.
