Right here’s what our analysis group uncovered in regards to the wide-ranging advantages of vitamin C supplementation.
Vitamin C advantages

That’s when a person named Linus Pauling advised the world to begin taking heavy doses of Vitamin C. In his ebook Tips on how to Stay Longer and Really feel Higher, he advisable megadoses (an precise scientific time period) of the vitamin to keep off the frequent chilly, amongst different issues.
Why did the world hearken to this man?
As a result of he was (and nonetheless is) thought-about one of many high scientific minds of all time (1). He just about single-handedly based the fields of quantum chemistry AND molecular biology. He was awarded two totally different Nobel prizes, in two totally different classes (chemistry and peace).
The person was good so the world listened when he advised us to take far more Vitamin C than anybody thought was potential. So what if it introduced on a “laxative” impact. Kidney stones? No sweat if it means no extra colds. The phrase unfold and shortly Vitamin C and “treatment for the frequent chilly” have been linked ceaselessly.
Though Linus Pauling’s recommendation could not have produced outcomes out the best way he hoped, individuals nonetheless line as much as purchase Vitamin C to today.
2. Extra scientific knowledge has poured in since Pauling’s ebook got here out
To try to assist individuals kind out the details, The U.S. Nationwide Library of Medication has an official authorities assertion on Vitamin C and colds: the analysis is “conflicting” (2).
This doesn’t appear very clear, and that’s as a result of the efficacy of Vitamin C relies on who you’re, the place you reside, and exactly what outcome you’re in search of whenever you take the complement.
No research have but been in a position to set up a hyperlink between taking a Vitamin C complement and stopping a chilly.
3. Vitamin C could do one thing for colds, however not what you could assume
Maybe should you’re a long-distance runner residing in Iceland, you will notice a profit from Vitamin C supplementation.

However the half in regards to the cold-weather endurance athletes holds true: the identical evaluation examine discovered an 8% likelihood that the chilly would finish sooner in the event that they took Vitamin C.

Medical doctors speculate that the rationale for the profit is as a result of these tremendous athletic cold-weather sorts have a Vitamin C deficiency. By dosing themselves with C, they’re merely bringing their ranges again as much as regular.
