What Food Has the Highest Level of B6?
While chickpeas are a standout, the title of "highest B6 food" can depend on serving size and preparation. When considering standard, accessible servings, canned chickpeas are exceptionally high, but they are not the only contender. Other potent sources include beef liver, fish like tuna and salmon, and various nuts and seeds. For example, some dried vegetables and specific nuts show incredibly high B6 content per gram, such as dried pasilla peppers and pistachios. The key is understanding that a balanced diet with a variety of these foods is the most effective strategy for meeting your needs.
The Top Contenders for the Highest B6 Content
When searching for the absolute highest concentrations, some specific foods stand out, though some may be less common in the average diet:
- Dried Pasilla Peppers: Dried pasilla peppers have been noted as having extremely high B6 levels, with one source reporting 4.2 mg per serving. This is a potent, though less common, option.
- Pistachio Nuts: Raw pistachios are another powerhouse source, containing up to 1.7 mg per serving, placing them very high on the list.
- Chickpeas: As mentioned, one cup of canned chickpeas provides 1.1 mg, making them a widely available and excellent source.
- Beef Liver: A three-ounce serving of pan-fried beef liver offers a substantial 0.9 mg of vitamin B6.
- Yellowfin Tuna: A three-ounce portion of cooked yellowfin tuna also provides 0.9 mg of B6.
- Lobster: Some data also highlights lobster as being very rich in B6, with 100g containing over 1mg.
A Comprehensive Look at B6 Food Sources
While the absolute highest foods are impressive, a varied diet is the best way to maintain optimal B6 levels. This section explores a wider range of high-quality sources, both plant-based and animal-based.
Plant-Based Sources of B6
For vegetarians, vegans, or those simply looking to add more plant-based nutrients, there are many excellent B6 sources. Glycosylated vitamin B6, a bound form of the vitamin, is common in grains and legumes, and while its bioavailability varies, these foods still contribute significantly to overall intake.
- Legumes and Soy Products: Aside from chickpeas, lentils, soybeans, and soy-based products like tofu and tempeh are great sources.
- Nuts and Seeds: Nuts and seeds are concentrated sources of B6. In addition to pistachios, sunflower seeds, sesame seeds, and walnuts are all rich in this nutrient.
- Starchy Vegetables: Potatoes and sweet potatoes are valuable dietary sources. One medium sweet potato can provide 15% of the Daily Value.
- Fruits: Many fruits contain B6, with bananas being one of the best-known examples. A single medium banana provides 0.4 mg of B6. Other options include avocados and prunes.
- Fortified Cereals: Many breakfast cereals are fortified with B6, offering a quick and easy way to meet a portion of your daily requirement.
Animal-Based Sources of B6
Animal products are generally excellent sources of the free form of vitamin B6, which is highly bioavailable.
- Organ Meats: Beef liver is one of the densest sources, but other organ meats also contain high levels.
- Fish and Seafood: Both tuna and salmon are rich in B6, along with other varieties like mackerel and sardines.
- Poultry: Chicken and turkey breasts are solid sources of B6.
- Lean Beef: Lean cuts of beef can also provide a good amount of this vitamin.

Why is Vitamin B6 Important?
Vitamin B6, or pyridoxine, is a water-soluble vitamin that plays a crucial role in numerous bodily functions. It acts as a coenzyme in over 100 enzymatic reactions, most of which are involved in protein metabolism. The body uses B6 to produce neurotransmitters like serotonin, which regulates mood, and norepinephrine, which helps transmit nerve signals. It is also essential for creating hemoglobin, the protein in red blood cells that carries oxygen, and for maintaining normal nerve function. A strong immune system also relies on adequate B6, as it helps the body produce antibodies and white blood cells. For pregnant women, B6 is vital for the baby's neurological development and can help alleviate morning sickness. It also assists in regulating blood sugar and breaking down carbohydrates for energy.
Signs of B6 Deficiency
While deficiency is uncommon in most developed countries, certain conditions and poor diets can increase risk. Symptoms of low B6 levels can include:
- Skin rashes: Eczema-like rashes or inflammation can appear, especially around the nose and mouth.
- Neurological issues: Peripheral neuropathy, characterized by tingling and numbness in the hands and feet, is a key symptom of severe deficiency.
- Mood changes: Depression, irritability, and confusion can occur due to B6's role in neurotransmitter production.
- Anemia: A specific type of anemia, microcytic anemia, can result from inadequate B6 because the body can't produce enough hemoglobin.
- Sore tongue and mouth: Glossitis (swollen tongue) and cheilosis (scaling on the lips and cracks at the corners of the mouth) are common signs.
- Weakened immune function: A poor immune response can be a result of B6 deficiency affecting the production of white blood cells.
Conclusion: Achieving Your B6 Goals
While chickpeas offer an excellent and accessible source of vitamin B6, a variety of foods contribute to your daily intake. To ensure you meet your needs, aim for a diet rich in a mix of animal and plant-based sources. Including fish like tuna or salmon, organ meats, starchy vegetables like potatoes, and a handful of nuts or seeds throughout the week can make a significant difference. For those with plant-based diets, chickpeas, lentils, and fortified cereals are reliable pillars. Ultimately, a balanced and diverse nutritional plan is the best way to support your overall health and prevent deficiency.
