If you are suffering from extreme fatigue, lethargy, muscle weakness, pins and needles, mouth sores, or cognitive problems including irritability, depression, or lapses in memory, it may be a sign that you are deficient in Vitamin B12 and could benefit from regular supplementation with Vitamin B12 booster injections.

​

The most common cause of Vitamin B12 deficiency is pernicious anaemia, however, it is estimated that 20% of the over 60s are deficient in B12, and 11% of those who follow a vegan diet are also deficient.

​

A healthy body needs Vitamin B12 to produce healthy red blood cells that can take oxygenated blood around the body and keep the central nervous system functioning correctly. If there is a lack of B12 in your system, it can lead to nerve damage.
