Vitamin B12 is a water soluable vitamin and is required by your body to form red blood cells containing the protein haemoglobin, which plays the primary role in transporting oxygen around the body. Vitamin B12 is also key in the functioning and development of both brain and nerve cells.

Low levels of B12 can often lead to feelings of weakness, lethargy and fatigue. A prolonged deficiency in B12 can also lead to conditions such anaemia therefore, it is important to spot issues as early as possible.
