It was biochemist Irvwin Stone who wrote in 1979 this “genetic approach, in which the gene is repaired or replaced so it will be capable of directing the synthesis of the active enzyme (gulonolactone oxidase)… would be a convenient solution to the problem, but the present ‘state of art’ in genetic engineering is not capable of doing this. Perhaps another 50 years will see this accomplished. Humans would then be able to perform the endogenous synthesis of ascorbate, just like the other mammals.” (~Irwin Stone, Homo Sapiens Ascorbicus, Medical Hyphotheses, Volume 5, 711-722, 1979.)
