B Vitamins play a strong role in keeping a happy head – particularly Vitamin B12, which aids in the creation of red blood cells and nerves, and B6, which is concerned with the production of neurotransmitters which send messages from the brain to the rest of the body.

You can find B6 in chickpeas, salmon, and chicken breasts, whilst B12 lives in Swiss cheese, Mozzarella, and tuna.
