Pantothenic acid (vitamin B5) is essential for energy production and plays a vital role in transforming food into usable fuel. It contributes to the creation of coenzyme A, which assists enzymes in breaking down and building fatty acids, as well as carrying out other metabolic processes. Vitamin B5 also aids cognitive function and helps combat tiredness and exhaustion. Good dietary sources of pantothenic acid include eggs, fish, meat, soft cheeses, mushrooms, nuts, and whole wheat flour.
