Benefits of Vitamin C in Fighting Off Winter Viruses
Old man winter is right around the corner.
That means most of us will likely be hit by a variety of cold or flu viruses. However, just because we’re exposed to them does not mean we are destined to catch them. In fact, by strengthening our immune system, almost anyone can fight off seasonal viruses.
What’s the best thing you can do to boost your body’s defenses?
It’s no secret that reliable ol’ vitamin C is our perennial favorite for keeping you healthy in this change of seasons. And for good reason. This essential nutrient works nothing short of a miracle as it pumps antioxidant protection into your body’s cells.
In fact, during the 2009 H1N1 outbreak, scientist discovered antioxidants such as vitamin C held the key to preventing the flu virus from wreaking havoc on our lungs. And, other studies have shown vitamin C particularly effective at fighting both swine and avian flu.
Of course, there is significant research including this study showing vitamin C can reduce ordinary cold and flu symptoms by up to 85%. A welcome relief to half the American population expected to take a hit as soon as the snow starts falling.
True, vitamin C is a powerful antiviral compound. But viruses aren’t the only winter foes vitamin C takes a strong stand against. Research shows it’s effective in helping you fight depression too. Plus, we shared a story previously on the miraculous recovery potential of vitamin C on bone fractures following a serious fall on ice.
In that case, just 5 grams per day did the trick.
How do you know if you’re getting enough vitamin C to fight winter viruses? We’ve covered that before right here.
But the short answer is, we recommend 3-6 grams of vitamin C daily in divided doses (i.e., upon waking up, with meals, and before bed) to provide plenty of vitamin C protection for boosting your immune system during the winter season; more when under stress or if a virus is taking hold on your body.
However, be sure to take only the best, purest form of vitamin C on the market. One that is buffered to eliminate acid buildup, and is corn-antigen free, fully reduced, 100% L-ascorbate. Most vitamin C is made from genetically modified corn. Our Beyond Health Vitamin C is and will always be GMO free!
Vitamin C is so basic to human biochemistry that getting the right amount daily should be the foundation of any winter wellness strategy.
