Vitamin C is very important, especially back when it was hard to come by on ships, which is why oranges were eaten on ships to prevent scurvy.
Yes, I love oranges, which I know help in the Vitamin C area. 
I love citrus too! One thing that is a complete myth is that vitamin C really doesn't show any signs of helping fight the common cold.
Really? I didn't realize that. I have a friend at work that would swear Vitamin C helps keep colds at bay lol!
They're kinda right, as there is some evidence to show that it may shorten the length of them.
Well, I just love the taste of oranges, so I'm glad it also has other benefits!
I know what you mean, it's like a win win haha. Vitamin C is also very well tolerated so that is good too.
Yes, I wished there was a bit less acid in it, as it tends to give me heartburn. I could live without that side effect.
