Thinking that the world is out to get you could be a symptom of a B12 deficiency (Image: Getty) When your body is not receiving the right amount of nutrients and vitamins, your health can deteriorate. However, one vitamin deficiency can pose a more significant risk to your long-term health than others, leading to damaging and sometimes permanent symptoms like mental disorders, infertility, and nerve damage. Vitamin B12 may not be as well-known as other nutrients but it's crucial for key bodily functions, including parts of your metabolism, and nervous and circulatory systems.
Due to its widespread use throughout the body, when these functions stop receiving enough B12, it can lead to serious problems, from chronic fatigue to paranoia and delusions. The usual causes of this deficiency are either biological through a form of anaemia, or dietary from following a vegan or plant-based diet. NHS England has emphasised that it's "important" to recognise the early warning signs of this deficiency, as it can cause permanent and "irreversible" damage if left untreated.
Most deficiencies are caused by your stomach being unable to process B12 due to some other condition, such as different forms of anaemia. In rarer cases, people who do not consume products containing B12, like fish and eggs, can develop the symptoms of B12 deficiency, though this can be avoided by taking multivitamins. function loadOvpScript(){let el=document.
