The History Of Vitamins: What Happened To Vitamins F Through Z?

There are vitamins A, B, C, D, E, but, other than vitamin K, have you ever noticed that there are no vitamins F, G, H, I, J or even Z? And have you ever wondered what happened to the majority of those vitamins between F and Z?


The History Of Vitamins F Through Z

In the 1900s, scientists noticed that certain foods prevented certain diseases. Pirates fought against scurvy, for example, by consuming lemon juice because of its rich vitamin C content. This led to the discovery of vitamins.

The alphabet was the system that scientists used to classify vitamins. In it, every letter was used to name a vitamin, but not all of the vitamins were important, so the list started to dwindle. For example, vitamins J and P had no effect on humans but did help rats and flowers. Similarly, vitamins H and I, were similar to vitamin B and so became part of the B complex.

Finally, scientists were left with 6 vitamins:

  • Vitamin A
  • Vitamin B
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Vitamin K


The Essential Vitamins

So we’re left with the 6 vitamins that the human body needs to function. In varying amounts, we need each of these vitamins on a daily basis to stay healthy. A multivitamin, like the myvitamins One For All, can make sure your body is getting all of the vitamins that it needs.
