That’s because “vitamin B12 is naturally present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products”, explains the National Institutes of Health (NIH).
“In addition, fortified breakfast cereals and fortified nutritional yeasts are readily available sources of vitamin B12 that have high bioavailability.”
According to the NIH, vitamin B12 is available in multivitamin/mineral supplements, in supplements containing other B-complex vitamins, and in supplements containing only vitamin B12.
How is it treated?
The treatment for vitamin B12 or folate deficiency anaemia depends on what’s causing the condition.
