The Mayo Clinic says: “Most people get enough vitamin B12 from a balanced diet.
“However, older adults, vegetarians, vegans and people who have conditions that affect their ability to absorb vitamin B12 from foods might benefit from the use of oral supplements.”
The organisation says when taken at appropriate doses, vitamin B12 supplements are generally considered safe.
It states: “While the recommended daily amount of vitamin B12 for adults is 2.4 micrograms, higher doses have been found to be safe.Your body absorbs only as much as it needs, and any excess passes through your urine.”
