In addition to promoting brain function and red blood cell production, vitamin B12 is essential for the health of nerve tissue. Animal products such as meat, fish, poultry, eggs, and dairy naturally contain it.
Fatigue: Because vitamin B12 deficiency affects the production of red blood cells, which are responsible for carrying oxygen throughout the body, feeling abnormally weak or exhausted may be a sign of the condition.
Sensations of tingling: numbness, or pins and needles: Vitamin B12 deficiency can result in nerve damage, which typically affects the hands and feet.
Vision issues: A severe vitamin B12 deficiency can cause damage to the optic nerve, which can cause distorted or blurry vision.
Breathing problems: Breathing problems, particularly during physical exertion, can be brought on by a reduced blood's ability to carry oxygen.
Dizziness: Low red blood cell production can cause a shortage of oxygen to the brain, which can cause lightheadedness or dizziness.
Cognitive problems: Memory loss, trouble concentrating, and brain fog can all be signs of a vitamin B12 deficiency. Vitamin B12 is essential for neurological function.
Changes in mood: Inadequate amounts of vitamin B12 may have an impact on the synthesis of neurotransmitters, which may lead to depression, irritability, or mood swings.
