B12 deficiency symptoms: Three signs in your feet that signal low B12 has caused ‘damage’

B12 is naturally found in:

• Meat and liver
• Fish
• Clams
• Milk and dairy products
• Eggs.

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.”
