3. A persistent facial rash
A sign of a vitamin B12 deficiency is both dermatitis and having a rash on your cheeks. The same applies if you have cracks in the corner of your mouth.
If you experience light sensitivity, anaemia, throat swelling and soreness, and a swollen tongue then these too could be attributed to a lack of B12. To help these symptoms, try eating more mushrooms, spinach, lamb, almonds, sun-dried tomatoes, turkey, asparagus and yoghurt.
4. Dry hair
Even a minor vitamin C deficiency can manifest itself, not just with dry hair, skin AND bleeding gums, but also if you bruise easily. Bruising is also a sign we're not getting enough vitamin D.

If this sounds like you, eat more oranges, kale, broccoli, strawberries, grapefruit, chili and kiwi fruit.
