Vitamin A Facts

There are several vitamin A facts that you should know. The first is that it's essential for general health, especially growth and development. To illustrate this fact you only need to realize how vitamin A was discovered. In 1907, scientists fed groups of rats different diets from different food categories trying to isolate nutrients. Their most stark finding was that the rats fed a diet deficient of what we now know is vitamin A absolutely failed to grow and became immediately sickly. The rats also recovered quickly when fed with supplemental foods that contained vitamin A. As you can see vitamin A plays a large role in keeping us healthy.
