Insufficient intake of B vitamins, energy-producing carbohydrates can not be completely burned. Adequate B vitamins are indispensable for the whole body cells to produce energy. B vitamins are a group, including 10 vitamins, and they are * * * compatible. It is useless to supplement one or more vitamins alone. It is best to choose natural and complete food sources to supplement. Adler Davis, a famous American nutritionist, said in "Scientific Concept of Dietary Nutrition": "In fact, only four foods contain complete B vitamins, namely yeast, animal liver, wheat germ and rice bran, especially yeast, which is the most abundant and the most reasonable proportion. Yeast is almost the only natural food containing high-quality protein and complete B vitamins. "

Nutritionists suggest that white-collar workers who are prone to fatigue and lack of vitality in summer and need coffee, strong tea and dessert to refresh themselves can drink nutritious yeast and juice between meals, which can effectively replenish their physical strength and eliminate fatigue. It is reported that many companies, schools and government agencies in Japan have regulations that you must drink nutritious yeast drinks before going to work in summer afternoon to eliminate fatigue, maintain vigorous energy and improve work and study efficiency.
