Eating oranges improves libido

Vitamin C, which is found in oranges, improves the libido. In a trial of 42 women, those who were given daily doses of 3,000mg of vitamin C had a higher libido and orgasms compared with the placebo group.

However, this dose is the equivalent of consuming about 10 litres of orange juice or 100 oranges. Plus the Food Standards Agency does not recommend anything higher than 1,000mg, as excess vitamin C can cause loose stool.
