The orgainstion states: “The best way to make sure you’re getting enough B12 and other vitamins is to eat a healthy diet that includes sources of essential nutrients.
“Vitamin B12 is plentiful in animal products such as fish, lean meat, poultry, eggs, and low-fat and fat-free milk. Fortified breakfast cereals also are a good source of B12 and other B vitamins.”
The NHS says: “During the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for the body to make vitamin D.”
It states: “Between late March/early April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet.”
