Influential genes: FUT2,TCN1,CUBN
Variations in the FUT2 gene have been associated with levels of certain glycoproteins, which can affect the uptake of vitamin B12 from the intestine.
Vitamin B12 is a water-soluble vitamin that is important for the function and development of brain and nerve cells, DNA formation and red blood cell synthesis. Adequate amounts of vitamin B12 in the body improve memory, increase concentration and reduce the risk of cardiovascular disease.
Vitamin B12 deficiency can cause weakness, fatigue, heart palpitations and shortness of breath due to the resulting anaemia (megaloblastic anaemia). Serious complications include nerve dysfunction in the spinal cord and periphery, as well as the development of psychiatric illness and dementia.
The required daily dose of vitamin B12 is covered by a normal diet in a healthy person. Foods rich in vitamin B12 are mainly of animal origin and include shellfish, beef liver, salmon, eggs and milk. It is hardly found in plant-based diets, so if you are vegetarian or vegan, be sure to supplement. In addition to dietary supplements, you can get it from fermented foods or in small amounts from seaweed.
