You really need B vitamins
The B vitamins are a group of eight water-soluble vitamins. They are coenzymes in a variety of metabolic processes in the body, and often work together—though each has a unique role as well. B vitamins are critical for building and repairing DNA and RNA, for producing energy, supporting mitochondrial function, and for synthesizing neurochemicals. And because they are involved in so many processes, deficiencies in B vitamins can lead to many problems. Are you getting enough B vitamins?
Vitamin B5 - Pantothenic acid
Pantothenic acid—B5—is everywhere. That doesn’t mean it isn’t important, and while deficiency is rare, it isn’t impossible. Minimally processed foods are great sources, and it is safe to supplement if needed. If you have any signs that could be linked to deficiency (fatigue, irritability, numbness and tingling, etc) it may be worth checking your levels, or just trying to make sure you are getting enough in your diet (maybe by adding a few teaspoons of nutritional yeast to your salad).
