Vitamin B12 injections offer several key benefits:

1. Increased energy levels and reduced fatigue.

2. Improved cognitive function, including memory and concentration.

3. Support for a healthy nervous system.

4. Promotion of red blood cell production and oxygenation.

5. Assistance in DNA synthesis and tissue repair.

6. Support for heart health by regulating homocysteine levels.

7. Enhancement of mood and overall well-being.

The frequency of B12 injections can vary depending on individual needs and the severity of deficiency. Some people may require injections weekly or bi-weekly initially, followed by less frequent injections once their B12 levels are stabilised.

B12 injections are generally safe and well-tolerated. However, some individuals may experience mild side effects such as injection site pain, redness, or swelling. In rare cases, allergic reactions or other adverse effects may occur.
