Vitamin C plays an important role in the body’s immune system, it protects cells from the damage caused by toxins or pollutants. Vitamin C is a water-soluble vitamin, meaning that it’s not stored in our body, so needs to be consumed daily. More than we need is generally lost in the urine, so supplements can end up being expensive wee! Did you know that an orange per day almost meets an adult’s Vitamin C needs?
Research has shown that vitamin C intake through diet and supplementation can help to lower blood pressure. In a recent trial looking at vitamin C intake supplementation in preventing and treating pneumonia, there was no clear conclusion that supplementation was beneficial. Supplementation does not prevent you from catching a cold, but may help to shorten the duration of symptoms by half a day.
Bottom line?
There is no need to supplement with Vitamin C throughout the year for the general, healthy population. If you feel concerned, seek professional advice. If you have a cold, it doesn’t hurt to take a supplement whilst unwell. To make sure you get enough, include these Vitamin C-rich foods:
– Citrus fruits e.g. oranges
– Tomatoes
– Capsicum
– Strawberries
– Broccoli
– Brussel sprouts
– Potatoes
