Water Soluble Vitamins: Sources, Functions, Deficiency

We know that all vitamins are classified into two categories: water soluble vitamins and fat soluble vitamins. Since our body cannot store water soluble vitamins, we need these vitamins regularly in small doses. The daily intake of water soluble vitamins can be through the consumption of foods as well as prescribed supplements.

How Do Water Soluble Vitamins Work?

At first, these vitamins go through our body parts freely. In the way, they absorb what are required to function properly, and finally, send out the excess things in our urine.

Because of heat, water soluble vitamins can be destroyed. They can be exposed to the air as well. If we cook them in water, the nutritional value is also reduced. So what is the best way to keep these vitamins value intact? It can be by steaming or grilling foods!

Examples of water soluble vitamins are vitamin B and C.

Vitamin B has various forms like:

  • Vitamin B1 (thiamin)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin)
  • Vitamin B5 (Pantothenic Acid)
  • Vitamin B6 (Pyridoxine)
  • Folic Acid
  • Vitamin B12 (Cobalamin)

Vitamin C (Ascorbic Acid)
