Effectiveness of vitamin C on cold symptoms
While vitamin C has garnered a reputation for warding off the common cold, there is a void of scientific studies that can actually prove the effectiveness of vitamins. In fact, much of the research is largely inconsistent and inconclusive.
For example, a 2007 clinical study noted by WebMD could not prove that 200 milligrams of vitamin C taken daily had any effect on efforts to reduce the frequency and symptoms of a common cold. The study further notes that vitamin C was only able to reduce the duration of the cold by a measly 8% at best.
Is vitamin C a fraud?
So, am I saying vitamin C is no better than a placebo for the common cold? I would not dare ! Instead, I turn to experts at the US Library of Medicine who question vitamin C’s ability to protect against colds in the first place.
In fact, studies from the National Institutes of Health show that yes, high doses of vitamin C can help shorten the duration of a cold, but the chances of it preventing a cold in the first place are slim to zero.
How Much Vitamin C Is Enough?
So, while popping vitamin C won’t scare away the common cold, it can shorten the duration of cold symptoms. After all, a natural way to boost immunity in a way that is closely related to vitamin C is to increase your vitamin levels in the first place. But timing is everything.
For example, the NIH reports that residents of colder climates (I’m looking at you, Buffalo, New York) may increase their chances of catching a cold if they take vitamin C supplements regularly, rather than taking a larger dose. important all at once and eliminate it quickly from the body through urination.
