Tag: Obsolete vitamins

In the 1920s, scientists isolated a factor from the 'water-soluble B' complex that was shown to promote growth in rats, labeling it vitamin G. However, this name has since disappeared from nutritional science, leading many to wonder what became of the 'missing' nutrient. The truth is that as vitamin research progressed, what was once called vitamin G was reclassified as a more familiar compound: riboflavin, or vitamin B2.

First discovered in 1905, the substance once identified as vitamin B13 is now known not to be a vitamin at all, but a naturally occurring organic compound called orotic acid. This shift in classification highlights key developments in nutritional science and a better understanding of how our bodies function.

Historically, the term 'vitamin B4' was used to refer to a few different compounds, but it has since been deemed an obsolete designation by nutrition science. In reality, there is no recognized **what is the vitamin 4 treatment** today, though the phrase may refer to modern intravenous (IV) vitamin therapy, a popular but controversial wellness trend.
