“Vitamin B12 deficiency is common among young people and especially common among people over 60 years of age. As we age, our bodies naturally produce less stomach acid and intrinsic factor, which are needed to absorb B12 from food,” she explained.
The brain and neurons need vitamin B12, and its deficiency contributes to brainwork and concentration difficulties. Long-term B12 deficiency increases susceptibility to dementia, Alzheimer's disease.
Vitamin B12 helps the body metabolize food, break down fats, proteins and carbohydrates, and produce energy. Its deficiency provokes fatigue and weakness, as well as rapid weight gain difficult to get rid of it.
Since B12 plays a huge role in the production of serotonin, vitamin deficiency can contribute to the development of symptoms of low mood, sleep disturbances, and depression.
Frequent infections are another hidden sign of vitamin B12 deficiency. It is necessary for the body to produce white blood cells, which ensure the optimal functioning of the immune system. The lower the level of B12 in the blood, the worse it repels attacks from viruses and other pathogens.
