History & Discovery :
**XVIIIth century: Sailors who sailed long distances - and didn't have access to consume enough fruits often suffered from scurvy (a serious disease that can go as far as causing tooth loss). An English naval doctor, James Lind, established a correlation between the consumption of citrus fruits and curing scurvy. He confirmed this hypothesis with the first "clinical trial" in the history of mankind.
1928: Vitamin C was isolated from lemon juice by Albert Szent Györgyi, who received a Nobel Prize for this discovery. Scurvy was therefore due to a vitamin C deficiency.
1933**: a Polish chemist, Tadeusz Reichstein, invented a process for synthesizing vitamin C from glucose.
