Yellow eyes, often a sign of jaundice, can be caused by several factors, including vitamin deficiencies. A vitamin B12 deficiency is one of the primary culprits linked to yellowing of the eyes. This deficiency can lead to anemia, which affects the liver’s ability to process bilirubin, a yellow pigment, thus causing jaundice-like symptoms.
What Vitamin Deficiency Causes Yellow Eyes?
How Does Vitamin B12 Deficiency Affect Eye Color?
Vitamin B12 is crucial for maintaining healthy red blood cells and nerve function. A deficiency in this vitamin can lead to megaloblastic anemia, a condition where the body produces abnormally large and dysfunctional red blood cells. These cells can break down easily, releasing bilirubin into the bloodstream. The liver may struggle to process the excess bilirubin, causing a yellow tint to the skin and eyes.
Other Symptoms of Vitamin B12 Deficiency
Besides yellow eyes, a lack of vitamin B12 can result in various other symptoms, including:
- Fatigue and weakness
- Shortness of breath
- Dizziness
- Numbness or tingling in the hands and feet
- Cognitive difficulties, such as memory loss or confusion
These symptoms highlight the importance of maintaining adequate levels of vitamin B12 for overall health.
What Are the Sources of Vitamin B12?
Vitamin B12 is primarily found in animal-based foods. Here are some excellent sources:
- Meat: Beef, pork, lamb
- Fish and shellfish: Salmon, tuna, clams
- Dairy products: Milk, cheese, yogurt
- Eggs
For those following a vegetarian or vegan diet, fortified foods and supplements can help meet daily vitamin B12 needs.
Can Other Deficiencies Cause Yellow Eyes?
While vitamin B12 deficiency is a common cause, other nutrient deficiencies can also lead to yellow eyes indirectly by affecting liver health or red blood cell production. These include:
- Iron deficiency: Can lead to anemia, affecting bilirubin processing.
- Folate deficiency: Similar to B12 deficiency, it can cause megaloblastic anemia.
Both deficiencies can contribute to jaundice-like symptoms, emphasizing the need for a balanced diet rich in essential vitamins and minerals.
How to Diagnose and Treat Vitamin B12 Deficiency
Diagnosing Vitamin B12 Deficiency
If you suspect a vitamin B12 deficiency, a healthcare provider can confirm it through:
- Blood tests: Measure vitamin B12 levels, red blood cell count, and bilirubin levels.
- Physical examination: Check for signs of jaundice and neurological symptoms.
Treating Vitamin B12 Deficiency
Treatment typically involves:
- Dietary changes: Increasing intake of B12-rich foods.
- Supplements: Oral supplements or injections, especially for those with absorption issues.
Early diagnosis and treatment can prevent complications and improve symptoms.

What Causes Yellow Eyes Besides Vitamin Deficiency?
Yellow eyes can be caused by liver diseases like hepatitis or cirrhosis, gallbladder issues, or certain medications that affect liver function. It’s important to consult a healthcare provider for a proper diagnosis.
Can Vitamin B12 Deficiency Be Prevented?
Yes, it can be prevented by consuming a balanced diet with adequate amounts of vitamin B12. For vegetarians and vegans, fortified foods or supplements are essential to meet daily requirements.
How Long Does It Take to Recover from Vitamin B12 Deficiency?
Recovery time varies depending on the severity of the deficiency. With treatment, symptoms can improve within a few weeks, but it may take several months for full recovery.
Are There Any Long-Term Effects of Untreated Vitamin B12 Deficiency?
Yes, if left untreated, vitamin B12 deficiency can lead to permanent nerve damage, cognitive impairments, and increased risk of cardiovascular diseases.
What Are the Best Supplements for Vitamin B12?
Cyanocobalamin and methylcobalamin are common forms of B12 supplements. Consult a healthcare provider to determine the best option for your needs.
