Which is the First artificially synthesized Vitamin?

The first artificially synthesized vitamin was Vitamin C (ascorbic acid). It was successfully synthesized in 1933 by the British chemist Sir Norman Haworth and his team. This breakthrough marked a significant achievement in the field of chemistry and nutrition, leading to the mass production of Vitamin C for medical and dietary use. Sir Norman Haworth’s work on Vitamin C synthesis also contributed to his receiving the Nobel Prize in Chemistry in 1937.
