Vitamin C Deficiency May Be an Independent Risk Factor for Stroke

Dr. Linus Pauling himself is said to have taken 12,000 mg per day. He noted that veterinarians recommended far higher doses of vitamin C for primates than what was recommended for people.

So he initially extrapolated the dosages from monkeys, and determined that humans likely need a minimum of six grams per day — 200 times more than the RDA.

While scurvy 壞血病 is the most well-known side effect of vitamin C deficiency, French researchers have also reported that those with vitamin C deficiency are at an increased risk for a lethal hemorrhagic stroke.11 According to the authors, vitamin C deficiency "should be considered a risk factor for this severe type of stroke."

They also pointed out that previous studies have found vitamin C may help regulate blood pressure, and that higher blood levels of vitamin C have been found to reduce stroke risk by more than 40 percent.

A 20-year long prospective cohort study12 in Japan found that those with the highest serum levels of vitamin C had a 29 percent lower risk for stroke compared to those with the lowest serum levels. Moreover, people who ate vegetables six to seven days a week had a 54 percent reduced risk of stroke compared to those who only ate vegetables two days or less per week.

A common denominator here is the way vitamin C affects your blood vessels. Vitamin C helps dilate blood vessels, and is required for the biosynthesis of collagen, which helps keep your blood vessels strong and intact. Lack of vitamin C can therefore lead to a weakening of your blood vessels, resulting in scurvy symptoms like subcutaneous bleeding, or the lethal hemorrhaging associated with hemorrhagic stroke.
