Feeling tired may be a normal reaction to lack of sleep or can be caused by various physical or mental conditions, like thyroid problems, diabetes, heart diseases, cancer or depression. Vitamin deficiency is only one of the possible causes of fatigue. If you suffer from excessive tiredness and consider taking vitamins, first talk to your doctor.
An adequate level of vitamin B12 maintains healthy nerves and blood cells. It also helps synthesize DNA. When you are deficient in this nutrient, a form of anemia called megaloblastic anemia occurs. According to National Institutes of Health, older individuals or those with certain digestive diseases, pregnant women, and vegetarians are at risk to develop a Vitamin B12 deficiency. Symptoms of vitamin B12 deficiency include tiredness, weakness, sore tongue, neurological symptoms, balance issues, memory deficits, confusion, and loss of appetite with consequent weight loss. A shortage of this nutrient can be easily corrected by supplementation with vitamin B12 either in oral or injectable form.
Vitamin B3 or niacin is involved in the metabolism of sugars, fats and proteins and helps maintain healthy skin and nervous system. According to University of Maryland Medical Center, vitamin B3 deficiency is rare, and alcoholics are at risk to develop it. Mild shortage of this vitamin may manifest with symptoms like tiredness, digestive problems, canker sores, red swollen tongue and depression. Doctors treat this deficiency by recommending a diet rich in B3 vitamin and supplementation with this nutrient.
Vitamin B2 or riboflavin is involved in the formation of the red blood cells and in sugar, fat and protein metabolism. It also has antioxidant qualities and therefore protects cells against damage from free radicals. Older people, those who have improper diet and those who drink alcohol excessively are at risk at developing B2 deficiency. Children with sickle cell anemia and iron deficit anemia are also prone to lower levels of riboflavin. Symptoms of B2 shortage include tiredness, eye fatigue, sensitivity to light, digestive issues, throat pain and inflammation. Doctors recommend a balanced diet along with vitamin B2 supplementation for the treatment of this nutrient deficiency.
Consult a qualified health care professional to find out if your tiredness is related to vitamin deficiency and if so, the optimal dosage required for treating your condition. Your doctor will also explain possible side effects and drug interactions.
