Vitamin supplementation has long been a strategy for people who are trying to prevent colds or fight them off. Drinking orange juice for vitamin C, eating lots of fruits, and more recently taking vitamin supplements like Emergen-C and Airborne are often recommended as ways to stay healthy. But do they work?
Are there Emergen-C side effects, find out below :
Emergen-c side effects
Research is inconclusive. Most studies that have looked at things like Emergen-C and Airborne haven’t found them to be very effective. Not only that, but according to Columbia University’s Health Q&A, the more vitamin C you take, the less your body absorbs. And if you get to really high doses of vitamin C, you’re likely to experience some unpleasant side effects, including kidney stones and increased oxygen demand (which is especially bad at high altitudes, such as in Boulder and Denver).
The daily recommended intake (DRI) of vitamin C has an upper limit of 2000 mg, and Emergen-C has 1000 mg. So if you’re taking it, you’re fairly likely to get over the upper limit and put yourself at risk for these side effects.
On the other hand, the Mayo Clinic does note that some people those living in extreme circumstances can benefit from taking extra vitamin C. The people listed as living in extreme circumstances including soldiers, those living in subarctic conditions, and marathon runners (so, presumably, long-distance triathletes and cyclists fall into this category as well).
Increased vitamin C intake has been linked to a decrease in the likelihood of getting a cold for these groups. So if you’re a member of one of these groups, taking extra vitamin C might not be a bad idea.
What it all comes down to is that no one vitamin or supplement is going to keep you from getting a cold. Make sure you’re getting enough vitamins and minerals in your daily diet by eating enough fruits and vegetables, get enough sleep, and take some time off of training when you start to feel sick. Using these easy methods should help you stay healthy and not put you at risk for any unpleasant side effects.
