Also known as cyanocobalamin, this vitamin is essential for psychological function, maintaining a healthy nervous system and reducing tiredness and fatigue. Our bodies need Vitamin B12 to manufacture red blood cells, allowing the body to provide oxygen to body tissues. If your B12 levels drop, your energy levels can too, leaving you feeling unable to tackle the day. Sufficient levels of B12 help to keep your physical co-ordination and nervous system in general in good health. 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.
