The importance of both kidney and liver in our body is enormous, because these two organs help us stay healthy. The roles of both organs are different from each other. The liver helps in processing the chemicals and controlling the metabolism, which breaks down the toxins and processes the nutrients. Whereas the kidney helps in filtering the system as it removes the liquid waste in the form of urine. Even though these organs have an enormous responsibility, most people neglect the fact of their own health. In order to preserve the organs, vitamins play an important part. In this blog, we will talk about some of the best vitamins for kidneys and liver function.
What are Vitamins?
Vitamins are organic substances which give energy to the body. It is essential to the body for normal functioning. They also aid with repairing any damaged tissues. There are a total 13 vitamins and are divided into 2 major types, Fat and Water soluble Vitamins. Fat soluble vitamins contains vitamins A, D, E, and K can be dissolved and stored in the liver. Whereas water-soluble vitamins contain vitamins C and B-complex.

The liver is the largest internal organ, and one of the most metabolically active organs of the body. It carries out more than 500 essential activities such as:
- Removing the alcohol, drugs, and environmental toxins from the body.
- Making bile to digest and absorb fat.
- Production of blood clotting proteins, as well as the production of albumin.
- Utilising carbohydrates, fats and proteins.
- Glycogen, iron, and fat soluble vitamins are stored.
- This vitamin is processed and activated in the body.
