Have you ever noticed cracks at the corners of your mouth, frequent eye fatigue, or unusual skin irritation? These may not just be small inconveniences but possible signs of vitamin B2 (riboflavin) deficiency. Riboflavin plays a key role in energy metabolism and maintaining healthy skin, eyes, and nerves. Without enough of it, the body can send early warning signals that should not be ignored. Let’s explore the most common symptoms of vitamin B2 deficiency and why this nutrient is so essential for daily health.
1. Cracks and soreness around the mouth
One of the earliest signs of riboflavin deficiency is angular cheilitis — painful cracks and redness at the corners of the lips. Many people think this comes only from dry weather, but nutrient imbalance is often a hidden factor.
2. Tongue inflammation and mouth discomfort
Deficiency can lead to a swollen, reddish-purple tongue, sometimes accompanied by a burning sensation. This condition, known as glossitis, makes eating uncomfortable and signals poor vitamin intake.
3. Skin problems
Lack of vitamin B2 can cause dry skin, rashes, and sensitivity to light. These symptoms often appear on the face, around the nose, or on the forehead, where sebaceous glands are active.
4. Eye fatigue and light sensitivity
Riboflavin plays an important role in eye health. Its deficiency may cause eye strain, burning sensations, or unusual sensitivity to light. Some people even experience blurred vision when deficiency is prolonged.
5. Fatigue and low energy
Since vitamin B2 helps convert carbohydrates, proteins, and fats into usable energy, insufficient intake can quickly lead to chronic tiredness. People may feel exhausted even after enough rest.
6. Anemia risk
In more severe cases, riboflavin deficiency contributes to anemia, leading to pale skin, dizziness, or difficulty concentrating. This happens because vitamin B2 is involved in red blood cell production and iron metabolism.
7. Nervous system effects
A lack of riboflavin can also affect the nervous system. Tingling in the hands and feet or mood changes such as irritability are sometimes linked to prolonged deficiency.

Vitamin B2 deficiency is more than a minor issue — it can affect multiple systems in the body. The good news is that it can usually be improved with diet. Foods like milk, eggs, almonds, mushrooms, spinach, and liver are excellent sources of riboflavin. By adding these regularly to meals, you can protect your skin, eyes, and energy levels more effectively. If symptoms persist or are severe, professional medical advice is strongly recommended.
