In 1927 Szent-Gyorgyi was credited with discovering and isolating an organic acid which could help prevent scurvy. A few years later, in the early 1930s, Szent-Gyorgyi and his research partner, Joseph Svirbely found that this organic acid was Vitamin C with chemical name "L-Ascorbic Acid".
Sailors, who would spend long periods at sea
with little or poor nutrition, would often suffer with scurvy and to
help avoid this dreaded disease they were given sacks of citrus fruits
to nourish themselves with during their journey. They knew at the time
that limes were good for them, but they didn't know why.
years that have passed, Vitamin C has gone on to be used to not only
prevent scurvy (a now rare disease) but as a general booster for the
immune system, especially to help in the prevention of colds and flu.
