Vitamin B-6 is prevalent in both animal and vegetable food sources. Liver, chicken, fish, green beans, field salad, wheat germ, nutritional yeast and bananas are particularly good food sources.
Vitamin B12 is naturally found in foods including meat (especially liver and shellfish), eggs, and milk products. Fortified breakfast cereals are a particularly valuable source of vitamin B12 for vegetarians and vegans.
While lacto-ovo vegetarians usually get enough B12 through dairy products or eggs, it may be found lacking in those practicing vegan diets who do not use multivitamin supplements or eat B12 fortified foods, such as fortified cereals (for example, Cheerios), fortified soy-based products, and fortified energy bars. Claimed sources of B12 that have been shown through direct studies[citation needed] of vegans to be inadequate or unreliable include spirulina (an algae), nori (a seaweed), barley grass, and human gut bacteria. Several studies[citation needed] of vegans on raw food diets show that raw food offers no special protection against B12 deficiency either. The only known vegan sources of substantial B12, aside from multivitamin supplements and fortified foods, are the Chinese herb Dang Gui (Angelica sinensis), used for centuries for treating anemia, and certain brands of fortified nutritional yeast.[citation needed]
Interestingly, certain insects such as termites have been found to contain B12.
Cyanocobalamin is also found in many energy drinks.

Good sources of vitamin B6 (aka Folic Acid) are: Folic acid -- liver, avocados, beans, beets, celery, chick peas, eggs, green leafy vegetables, nuts, oranges and orange juice, soybeans, and whole wheat products. Vitamin B6 -- Rice and wheat bran, sunflower seeds, avocados, bananas, corn, fish, lean meat, liver, nuts, poultry, brown rice, soybeans, whole grain.
First, about 75% of the vitamin B12 in the American diet is from meat, fish, and poultry, with most of the rest coming from dairy products. There is no vitamin B12 in fruits, vegetables, legumes, grains, nuts, or seeds.
Second, although vitamin B12 deficiencies are also rare, they happen. But the problem is usually not related to dietary intake. Other than perhaps very strict vegetarians, most of us consume plenty of this vitamin. The main cause of a deficiency here is lack of what's called the "intrinsic factor". The intrinsic factor is a chemical secreted in the stomach that allows vitamin B12 to be absorbed through the intestinal wall. People who don't produce the intrinsic factor must receive therapeutic doses of B12 injected into the muscle.
The truth is, if you are eating a nutrient-rich diet and taking proper care of your food, you probably don't need folic acid, vitamin B6, vitamin B12, or any other vitamin B supplements. However, supplements are normally not toxic and should do you no harm.

Keep in mind that the deficiency of vitamin B6 is rare because most all foods contain b6....Vitamin B6 is found in a wide variety of foods including fortified cereals, beans, meat, poultry, fish, and some fruits and vegetables . I could.. (but the list would be too long) name some of the foods that contain vitamin B6... i.e. banana, oatmeal,tomato juice, sunflower seeds, salmon, tuna... etc.. The food that contains the most is probably the prepared breakast ready-to-eat cereal fortified and below that is the ordinary baked potato.
As far as Vitamin B12....Vitamin B12 is found in all foods of animal origin, including dairy, eggs, meat, poultry, and fish.
