Sardines are small, soft-boned saltwater fish. They’re usually sold canned in water, oil or sauces, though you can also buy them fresh.
Sardines are extremely nutritious because they contain virtually every single nutrient in good amounts.
Beef is an excellent source of vitamin B12. One grilled flat iron steak provides almost 200 percent of the RDI for vitamin B12.
Also, the same amount of steak contains reasonable amounts of vitamins B2, B3 and B6
This source of vitamin B12 may work well for vegetarians and vegans as it’s synthetically made and not derived from animal sources.
Research shows that eating fortified cereals daily helps increase vitamin B12 concentrations.
