Lacking energy, feeling constantly tired and sleepy, and another coffee only works for a little while? This is a common symptom of overexertion, but it doesn't always mean a vitamin deficiency. Energy levels depend on the amount of sleep, stress, diet, physical activity, hydration, and the proper functioning of the body. Some vitamins can help fight fatigue, but mainly when the body truly lacks them.

Where does fatigue and low energy come from? Which vitamins are worth using for low energy levels? Can fatigue result from an electrolyte deficiency? When should you get tested instead of reaching for energy-boosting supplements?
