Researchers have claimed that a 3p tablet could make you 'happier', reduce anxiety and combat fatigue.

If you often find yourself feeling drained, weak and low, it might be due to a lack of vitamin B12. Numerous studies suggest that vitamin B12 can effectively address these issues. In fact, depression has been linked to a deficiency in vitamin B. Vitamin B12 is naturally present in animal products like eggs, fish and red meat. Some individuals may consume enough B12, but their bodies fail to absorb it properly.

A deficiency in vitamin B12 can impact your health in various ways. Boots is offering a bottle of 180 Vitamin B12 Tablets for £6.08 - which works out at just 3p per pill. However, it's crucial to consult with your doctor to rule out any other potential health conditions before making any drastic changes to your diet or lifestyle, reports Bristol Live.

One study published in the Journal of Psychopharmacology found evidence suggesting a decrease in vitamin B12 was associated with an increase in depression. Another study confirmed that vitamin B12 can influence the body's 'happy' chemicals, including serotonin and dopamine.

Researchers stated that a B12 deficiency can affect mood, emotions and sleep, potentially leading to psychiatric disorders such as anxiety. Some psychological benefits from boosting your B12 levels may include:

  • Calming stress and anxiety to balance moods.
  • Psychological wellbeing.
  • Assisting in normal nerve growth and development.
  • Improving communication between nerve cells.
  • Promoting stable adrenal function.
  • Providing emotional and mental energy.
  • Helping with the ability to concentrate.
  • Bolstering memory function.

Another study has highlighted the significant impact vitamin B12 can have on mood, with findings stating: "Psychiatric manifestations of vitamin B12 deficiency can include depression, apathy, irritability, dementia, catatonia, delirium, and hallucinations. Higher vitamin B12 levels are thought to be associated with a more favourable outcome in depression."

The NHS confirms that vitamin B12 is crucial for maintaining a healthy nervous system and that lacking in it can lead to severe fatigue and energy depletion. Research indicates that insufficient vitamin B12 levels may result in exhaustion, weakness, memory loss, and other nervous system issues.

For those looking to boost their vitamin B12 intake, a range of protein-rich foods are available, including lean meats, poultry, eggs, seafood, beans, peas, lentils, nuts and seeds, and soy products. Particularly great sources of this vital nutrient are fish and red meat.
