Why is high folic acid intake deceptive regarding B12 deficiency?
Answer
It can mask symptoms of a true vitamin B12 deficiency
Folic acid and vitamin B12 have a complex relationship in the body. While high amounts of folic acid may alleviate the fatigue associated with a deficiency, it does not correct the underlying health issues caused by a lack of vitamin B12. By masking these symptoms, individuals may be prevented from seeking the necessary medical diagnosis and treatment for the B12 deficiency, potentially allowing the underlying condition to persist or worsen without detection.
