Vitamins, keeping us in good health

What are vitamins?

Vitamins are some sort of organic chemical and nutrient that are present in all living things, be it humans, animals, or plants. Vitamins are very important and are needed to sustain our life. Humans get vitamins through the food they eat as our body usually does not in amounts that are enough to sustain our life. It should be noted that humans' vitamins needs are vastly different than that of animals or plants as we have different biology. There are 13 different vitamins that are currently recognized.

Where do we get our vitamins?

We (humans) get our vitamins from food sources mainly, although Vitamin D is produced in our skin by exposure to the sunlight - or ultraviolet B light from the sun, to be precise. The vitamins that we absorb from food usually come from healthy alternatives such as fruits, vegetables, and meat. Therefore it is very vital that we should have a balanced diet that involves proper portion of every type of food to get the optimal amount of vitamins.

Besides food however, we can take vitamin pills nad supplements in the event we cannot receive enough vitamins through our daily food intake.
