What Vitamin Deficiency Causes You to Feel Cold and Tired?

Feeling cold and tired is a common symptom that can result from several vitamin and mineral deficiencies. Understanding which deficiencies contribute to these feelings can help you take action to improve your energy levels and body temperature regulation.

1. Iron Deficiency

Iron deficiency is one of the most common causes of feeling cold and tired. Iron is essential for producing hemoglobin, a protein in red blood cells that carries oxygen throughout your body. Without enough iron, your body cannot effectively transport oxygen, leading to symptoms like fatigue, cold sensitivity, and weakness. This condition is known as iron deficiency anemia.

Symptoms of Iron Deficiency:

Persistent fatigue
Pale skin
Cold hands and feet
Shortness of breath

Iron can be found in foods like red meat, spinach, beans, and fortified cereals. In some cases, supplements may be necessary.

2. Vitamin B12 Deficiency

Vitamin B12 plays a critical role in the production of red blood cells and energy metabolism. A deficiency in this vitamin can result in vitamin B12 deficiency anemia, which also contributes to cold intolerance, fatigue, and weakness. People who follow vegetarian or vegan diets, or those with absorption issues, are particularly at risk.

Symptoms of Vitamin B12 Deficiency:

Tiredness and weakness
Difficulty concentrating
Pale or yellowish skin
Cold sensations, especially in extremities

B12 is found in animal products such as meat, dairy, and eggs. For those at risk of deficiency, fortified foods or supplements can help.

3. Folate (Vitamin B9) Deficiency

Folate deficiency, like B12, can lead to a form of anemia called megaloblastic anemia. This condition impairs the body’s ability to produce healthy red blood cells, resulting in fatigue and cold sensitivity. Folate is essential for DNA synthesis and cell division, making it particularly important during periods of rapid growth, such as pregnancy.

Symptoms of Folate Deficiency:

Weakness and fatigue
Pale skin
Heart palpitations
Feeling cold, particularly in colder environments

Folate-rich foods include leafy greens, beans, peas, and fortified grains.

4. Vitamin C Deficiency

Though rare in developed countries, a deficiency in vitamin C can interfere with iron absorption, leading to anemia. This can contribute to cold intolerance and fatigue. Vitamin C is also important for immune function and skin health.

Conclusion

Feeling constantly cold and tired may be a sign of an underlying nutrient deficiency, such as low levels of iron, B12, folate, or even vitamin C. If you suspect you might be deficient in any of these vitamins, it’s essential to adjust your diet or consider supplementation.
