Vitamin B12 deficiency can negatively impact your overall health over time. If you have a vitamin B12 deficiency, you may be experiencing fatigue brought on from factitious anemia. Vitamin deficiencies may also be responsible for fatigue, memory loss, physical numbness and dementia.

At LetsGetChecked we have identified 6 foods to boost your B12.


What is Vitamin B12?

Vitamin B12 is one of the most impactful minerals in determining energy levels. It is a water-soluble vitamin found naturally in certain foods, largely animal products. It can be added to non-natural sources and taken as a supplement. The recommended daily intake of vitamin B12 is 2.4 micrograms, this equates to 100 grams of cooked Atlantic salmon.

Vitamin B12 is responsible for neurological function, producing DNA, maintaining a healthy nervous system and generating red blood cells which carry oxygen around the body. It is an essential nutrient in pregnancy.

Folate, also known as vitamin B9 and vitamin B12 need one-another to work efficiently. The formation of healthy red blood cells requires vitamin B9 and B12. They should be taken in a balanced supplement as the effects of both vitamins can mask the symptoms of a deficiency in the other. Folate (B9), vitamin B12 and iron interact with one-another intrinsically. If one mineral is insufficient, the others will cease to carry out their functions properly. This is the reason it is suggested that they are taken in balanced proportions during pregnancy.

What are the symptoms of Vitamin B12 Deficiency?

A deficiency in vitamin B12 is responsible for symptoms ranging from fatigue to depression. Vegetarians and vegans are often lacking in vitamin B12 as the mineral is not found in plant-based foods. The body cannot produce the mineral independently. In general, symptoms may include:

  • Fatigue
  • Pale skin
  • Dizziness/feeling faint
  • Loss of vision
  • Numbness/Tingling on the skin
  • A smooth tongue
  • Feeling low or depressed
  • Memory Loss
  • Constipation/gas/changes in appetite

A vitamin B12 deficiency can lead to anaemia in which red blood cells, that are lacking in oxygen are not are not serving organs correctly. Anaemia is the most common blood disorder in the U.S with a reported 3.5 million sufferers of the condition.

A recent study on Vitamin B12 and Parkinson's Disease

A recent study on behalf of the Parkinson’s Group illustrates that those who are diagnosed with Parkinson’s disease are more likely to develop symptoms faster if they have a deficiency in vitamin B12. This research suggests that supplementation could postpone early symptoms in patients who are suffering from Parkinson’s including cognition and mobility.

Cereals fortified with vitamin B12 may be a particularly valuable source for vegetarians. Processed foods are not the answer for all meat replacements and should be eaten in moderation alongside a balanced diet to ensure optimal health.

Cheese, which is notoriously known for being fattening is packed full of calcium. Dopamine is one of our feel-good neurotransmitters.
