Vitamin B complex is a group of vitamins that are essential to many functions in the body, especially the nervous system, energy metabolism, and red blood cell production. However, because B vitamins are water-soluble, the body cannot store them for long. That is why we need to get them regularly from the foods we eat. If the body does not get enough vitamin B complex, it can affect your health and lead to symptoms such as the following.
Warning Signs That Your Body Is Deficient in Vitamin B Complex
Symptoms of vitamin B complex deficiency may vary depending on which B vitamin is lacking, but common signs generally include the following.
- Fatigue and weakness: This is a common symptom because B vitamins play an important role in converting food into energy. When you are deficient in B vitamins, the body can feel tired and exhausted even without heavy activity.
- Nervous system problems: B vitamins, especially vitamins B1, B6, and B12, play an important role in nervous system function. A deficiency may cause numbness in the hands and feet, muscle weakness, depression, anxiety, poor memory, and reduced concentration.
- Skin problems: B vitamins such as riboflavin (B2) and biotin (B7) help nourish the skin. A deficiency may lead to dry, cracked, flaky skin or mouth sores.
- Anemia: Vitamin B9 (folate) and vitamin B12 are important for red blood cell production. A deficiency may cause anemia, with symptoms such as lightheadedness, dizziness, easy fatigue, and pale skin.
Who Is at Risk of Vitamin B Complex Deficiency?
- People who do not eat a complete diet from all 5 food groups: especially those who do not consume meat, eggs, milk, or grains, which are important sources of vitamin B complex.
- Older adults: The absorption of B vitamins may decrease with age.
- Pregnant and breastfeeding women: The body needs more vitamin B complex to support the baby’s growth.
- People who regularly drink alcohol: Alcohol interferes with the absorption of B vitamins.
- People with certain chronic diseases: such as diabetes, kidney disease, and Crohn’s disease.
Prevention and Treatment of Vitamin B Complex Deficiency
- Eat a balanced diet from all 5 food groups: Focus on foods rich in vitamin B complex, such as whole grains, meat, eggs, milk, leafy greens, and legumes.
