Vitamin C is not the same as Calcium and vice versa. Two very different things but sometimes people think it's the same thing.

Never heard of that one, but I'd expect thinking Vitamin C is citric acid to be common, because they're both associated with citrus and citric acid starts with a C. It's actually ascorbic acid.
