Additionally, vitamin B12 is involved in the metabolism of fatty acids and amino acids, contributing to energy production.
A deficiency in vitamin B12 can manifest in various ways, including fatigue, weakness, shortness of breath, and neurological symptoms such as numbness or tingling in the hands and feet. Given its importance, it is crucial to consume adequate amounts of vitamin B12 through diet or supplements.
