My daughter just recently developed a cold and my concerned wife asked if she needs to start her on extra Vitamin C supplement. The same question has been asked by my patients regarding the need for taking Vitamin C tablet considering that diabetic patients are prone to develop colds.
Based on the recent analysis of several studies looking at Vitamin C, no conclusive evidence so far can say that Vit C is helpful for common colds. It has not been shown to prevent the onset of colds nor can it reduce the severity of colds.
The daily intake of Vitamin C is also discouraged since your daily requirement can easily be taken from regular intake of citrus fruits, apples and melon, vegetables like broccoli, spinach and cauliflower as well as, potatoes and tomatoes. These are foods that are easily available and therefore negates the need for us to take additional Vitamin C tablet. The recommended daily allowance recommended by the US Food and Nutrition Board is only 85 mg/day…more than the usual dose of a regular Vitamin C which is between 200 mg to 500 mg per tablet. I even have patients consuming mega doses around 1000 to 2000 mg/day.
Remember, too much Vitamin C can be harmful…it has been shown to result in kidney stones, gastritis, nausea and diarrhea.
To determine if you’re taking too much Vitamin C, check your urinalysis…a (+) ascorbic acid means, you’re just excreting the excess Vitamin C that the body does not need.
Don’t Depend on Supplements…
Rely on Your Daily Intake of Fruits and
Vegetables to Keep Colds Away!!!
