Regular exercise an also help boost your energy level. If your mobility is limited, start off slow and gradually increase your duration and intensity, being mindful of any injuries or limitations. Simply starting a regular walking program can be one of the best exercise programs.
If these steps don't help the problem, your doctor can do a blood test to see if you have any vitamin deficiencies.
Some common vitamin deficiencies that could lead to a lack of energy include:
Vitamin B12: A lack of vitamin B12 can cause fatigue, as well as neurological problems, which can affect your memory, balance, and concentration. B12 is mainly found in animal sources, but even if you eat meat and eggs, you may not have adequate B12 levels because some people don't absorb B12 well. Even if your multivitamin contains B12, you may need additional B vitamins beyond what is included in the average multivitamin. When taking B12 supplements, sublingual tabs (which dissolve under the tongue), are usually absorbed better than pills.
Vitamin D: A vitamin D deficiency can cause fatigue and depression. Studies have shown that approximately seventy-five percent of Americans have low levels of vitamin D. Because vitamin D is found in very few foods, you need to get your vitamin D from either supplements or from direct exposure to sunlight. Read more about vitamin D and its relation to obesity.
Iron: According to the Centers for Disease Control and Prevention, iron deficiency is the most common nutritional deficiency in the United States. In addition to fatigue, iron deficiency can impair your motor skills and your brain function, making it hard to think clearly and process information. To increase your absorption of iron, take an iron supplement at the same time as a source of vitamin C.
