Vitamins can be divide into two parts. They are fat-soluble and water-soluble vitamins.


Let’s discuss something about fat-soluble vitamins here. Fat-soluble vitamins do not excrete through urine.

So it gets stored in fat and liver. Since these vitamins can be stored normally there won’t be any deficiency in these vitamins.

And these vitamins can cause toxicity, especially vitamin A and D can cause when you take more than required. Check my other blogs about vitamin E.

Absorption of these vitamins is not easy. It will depend on few things like gut health and pancreas.
