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).
