Vitamin E

Vitamin E was introduced in Creatures 1 as a Fat Soluble vitamin, deficiency can cause infertility. Despite this description, it was not included in any official COBs, or referenced anywhere in the genome, making it an unused chemical.

In Creatures 2, it had a protective effect on the uterus, and could be found naturally in the Tantris Berry or injected with the Advanced Science Kit.

By Creatures 3/Docking Station, it was contained in the Medicine maker's Vitamin Potion along with Vitamin C. It is described as Keeps reproductive organs healthy.
