When this vitamin isn't present, brain function declines  

B12 deficiency can harm brain health and cause neurological disorders. Vitamin B12 helps produce myelin, which protects nerve fibers, and maintains the nervous system. This vitamin is needed to make brain-regulating neurotransmitters.  

Cognitive Impairment: Lack of adequate B12 can lead to memory loss, confusion, and cognitive decline, mimicking some of the symptoms commonly associated with dementia. 

Neuropathy: Vitamin B12 deficiency can cause nerve damage, which might lead to tingling and numbness in the hands and feet, and can affect motor and sensory functions. 

Mood Changes: Deficiencies can also influence mood, contributing to conditions like depression and anxiety. 

Fatigue: B12 is essential for energy production in the body, and a deficiency can lead to feelings of fatigue, which affects overall brain function and alertness. 

Sources of Vitamin B12 To prevent deficiency, it is important to consume adequate amounts of vitamin B12, which is primarily found in animal products. Good dietary sources include: – Meat (especially liver and other organ meats) – Fish and shellfish (such as salmon and clams) – Dairy product

For those who are vegetarian or vegan, getting enough B12 can be more challenging, as plant-based foods do not contain significant amounts of B12. In such cases, fortified foods (like some plant milks, soy products, and breakfast cereals) or supplements might be necessary.

Monitoring and Treatment Consult a doctor if you suspect a B12 shortage. They can suggest blood testing to confirm the deficit and supplements if needed. Vitamin B12 deficiency can be managed and prevented with adequate nutrition and monitoring.
