Our body requires energy and the amount depends on the duration and type of activity. Energy is measured in Calories and is obtained from the body stores or the food we eat. Glycogen is the main source of fuel used by the muscles to enable us to undertake both aerobic and anaerobic exercise. If you have low glycogen stores, you will feel constantly tired, performance will be lower and you will be more prone to injury and illness. A balanced nutrition is necessary for good health:

Proteins - essential to growth and repair of muscle and other body tissues

Fats - one source of energy and important in relation to fat soluble vitamins

Carbohydrates - our main source of energy

Minerals -  inorganic compounds occurring in the body and which are critical to normal body functions

Vitamins - water and fat soluble VITAMINS play important roles in many chemical processes in the body to yeald energy

Water - essential to normal body function - as a vehicle for carrying other nutrients and because more than  60% of the human body is water

Roughage - the fibrous indigestible portion of our diet essential to health of the digestive system

Understanding what vitamin is good for energy can help you balance your diet to minimize fatigue, lethargy, and general feeling tired. If you already feel those symptoms, you may have a deficiency in one or more of the essential energy vitamins that help keep your body active. The right vitamins in a balanced diet and healthy lifestyle will keep you energetic and physically fit.
