Symptoms of Excess Vitamin B12
Introduction to Vitamin B12 and Its Importance
Vitamin B12, also known as cobalamin, is essential for cellular metabolism, DNA synthesis, and mitochondrial function. While deficiency in this vitamin can lead to significant health issues, excessive intake can also result in adverse effects.
Common Symptoms of Excess Vitamin B12
Dermatological Symptoms: Acne and Facial Ruddiness
One of the notable symptoms of excessive vitamin B12 intake is the development of acne and facial ruddiness. A case report highlighted a young woman who developed acne and facial redness after consuming multiple high doses of cyanocobalamin for pernicious anemia treatment.
Neurological and Psychological Symptoms: Anxiety, Insomnia, and Akathisia
Excessive vitamin B12 can also lead to various neurological and psychological symptoms. These include anxiety, insomnia, and akathisia (a state of agitation and restlessness). The same case report mentioned earlier also documented these symptoms, which improved after discontinuing the high doses of vitamin B12.
Cardiovascular Symptoms: Palpitations
Palpitations, or the sensation of a rapidly beating heart, have been reported as a symptom of too much vitamin B12. This was observed in the case of the young woman treated with high doses of cyanocobalamin.
Headaches
Headaches are another symptom associated with excessive vitamin B12 intake. This symptom was also noted in the case report of the young woman undergoing treatment for pernicious anemia.
Conclusion
While vitamin B12 is crucial for various bodily functions, excessive intake can lead to several adverse effects, including acne, facial ruddiness, anxiety, insomnia, akathisia, palpitations, and headaches. It is essential to monitor and regulate vitamin B12 intake to avoid these potential side effects.
