Before we look into the benefits of vitamin B for our nervous system and metabolism, we first have to understand what the nervous system is and also what metabolism is. To put it simply, the nervous system is a complex collection of nerves and specialized cells known as neurons which transmit signals between different parts of the body. For example, when someone touches something hot, the neurons would transmit that information to the brain and the brain would then transmit information to our muscles to move our hand away from it. Without the nervous system, we would have no sense of touch. Metabolism can be explained simply by separating it into two categories, catabolism which breaks molecules down to obtain energy and anabolism, which synthesizes compounds that are needed by cells. These two are vital components to the body and therefore we should maintain them.
The B vitamins that maintain our nerve structure are B1,B5, B6 and B12. Vitamin B1 helps by reducing pain and inflammation levels, while also preventing cellular damage. Vitamin B5 regulates the autonomic nervous system by producing neurotransmitters, which transmits messages within the nervous system. Vitamins B6 helps with the covering of our nerve endings, which are the million points on the surface of our body that send messages to our brain when we feel sensations like heat,cold and pain. Finally, the body requires vitamin B12, a deficiency of which will cause peripheral neuropathy. The vitamins mentioned above are also associated with maintaining metabolism to help convert the nutrients we get from the food we consume into energy to fuel our body. B1, B5 and B12 enable the body to metabolize carbohydrates, proteins and fats more effectively, therefore allowing us to obtain more energy.
