B12 is naturally found in:
- Meat and liver
- Milk and dairy products
Plant-based sources of vitamin B12 include yeast extract, fortified plant milks and fortified breakfast cereals.
“If you’re following a plant-based diet, taking a vitamin B12 supplement can help prevent a deficiency,” says Holland and Barrett.
The health body continues: “Breast-feeding mothers could also consider a supplement, as they need an extra 0.5mcg a day.”
