Battle tiredness and fatigue with these vitamin B12 supplements

There’s nothing worse than feeling tired and listless, especially when you’ve already been trying to tackle the problem by making sure you’ve been getting enough good-quality sleep a night. Sometimes it’s not just your life choices making you tired, your fatigue could have more to do with the foods (or lack of) that you’re putting in your body.

One of the most important vitamins for a normal and healthy energy-yielding metabolism is vitamin B12. Also known as cyanocobalamin, this vitamin is also essential for psychological function, maintaining a healthy nervous system and reducing tiredness and fatigue.

Vitamin B12 naturally occurs in animal products, like meat and dairy, and can also be found in fortified vegan foods like plant milks, faux-meats, breakfast cereals and yeast extracts.

Long-term vegans who avoid fortified products are at a particularly high risk of deficiency and should take supplements to make up for this.

What are the benefits of B12?

Red blood cells: our bodies need vitamin B12 to manufacture red blood cells, allowing the body to provide oxygen to body tissues.

Energy-yielding metabolism: if B12 levels drop, your energy levels can too, leaving you feeling unable to tackle the day. A good level of B12 will help arm you with the energy to get through any day

Nervous system function: sufficient levels of B12 help to keep your eyes, physical co-ordination and nervous system in general in good health

Psychological function: taking enough B12 can ensure your memory functions normally.

  • Timed release 1000 µg Vitamin B12
  • Contributes to the reduction of tiredness & fatigue
  • Suitable for vegetarians and vegans
