19 Thiamin or B-1 Helps to convert carbohydrates to energy Deficiency: Fatigue, nausea, depression, nerve damage Foods: Pork, beef, liver, peas, seeds, legumes, whole-grain products, and oatmeal

20 Riboflavin or B-2 Key to metabolism and red blood cells Deficiency: Dry, scaly skin Foods: Milk, yogurt, cheese, whole-grain breads, green leafy vegetables, meat, and eggs
