**Vitamin B12 can be stored in our body.**

Vitamin B12, also known as cobalamin, is the only B group vitamin that can be stored in significant amounts in our body. It is a water-soluble vitamin that plays a vital role in various bodily functions.

**Storage in the Liver:**

Vitamin B12 is primarily stored in the liver. When we consume foods rich in vitamin B12, it is absorbed in the small intestine and then transported to the liver via the bloodstream. Once in the liver, vitamin B12 is bound to a protein called transcobalamin and stored for future use.

**Long-Term Storage:**

The liver has the ability to store vitamin B12 for an extended period. On average, the liver can store enough vitamin B12 to last from several months to several years, depending on an individual's dietary intake and absorption capacity.

**Release and Utilization:**

When our body needs vitamin B12, it is released from the liver and transported to the cells where it is required. The cells utilize vitamin B12 for various functions, such as the production of DNA, red blood cell formation, nerve cell maintenance, and the synthesis of myelin, a protective covering for nerves.

**Dietary Sources:**

Vitamin B12 is primarily found in animal-based foods such as meat, fish, eggs, and dairy products. Therefore, individuals who follow a strict vegetarian or vegan diet may be more prone to vitamin B12 deficiency as they may not consume adequate amounts of this vitamin through their diet.

**Importance of Adequate Intake:**

While vitamin B12 can be stored in our body, it is still essential to maintain an adequate intake of this vitamin through diet or supplementation. Regular consumption of vitamin B12-rich foods or supplements ensures that our body's stores are replenished and that we have a continuous supply of this vital nutrient.

In conclusion, among the B group vitamins, only vitamin B12 can be stored in significant amounts in our body. It is stored primarily in the liver and can be utilized for various bodily functions when needed. Adequate intake of vitamin B12 is crucial to maintain optimal health and prevent deficiencies.
