Vitamin B-6, or pyridoxine, is one of eight B vitamins necessary for vital bodily functions. Foods that contain vitamin B-6 include milk, salmon, eggs, bananas, chickpeas, and avocado.

Vitamin B-6 is often lacking in the average American diet. It’s available in supplement form, but you can also up your intake with these 15 foods. It’s always best to take in your vitamins through foods.

A vitamin B-6 deficiency can cause serious health problems. Having too little can negatively affect your central nervous system. This is especially true for children. Making sure both kids and adults drink milk every day can help keep levels high.

One cup of cow or goat’s milk provides 5 percent of the recommended daily value of vitamin B-6. Skim and 1 percent milk are low-fat, nutritious choices. Milk also provides high amounts of vitamin B-12 and calcium. If downing a glass of milk isn’t your cup of tea, try pouring it over a fortified low-sugar breakfast cereal instead.

Vitamin B-6 is a water-soluble vitamin, found in the whey protein content of cheese. The more whey the cheese has, the more B-6 it is likely to contain. Other water-soluble nutrients found in whey include thiamin (vitamin B-1), riboflavin (vitamin B-2), folate, and niacin (vitamin B-3). The cheese highest in whey is ricotta.

Adored for its smooth texture and mellow taste, ricotta is commonly found in many Italian specialties, including lasagna and cheesecake. It’s also used in quiche and in pancakes, such as this delicious lemon and blueberry version.

This heart-healthy fish has one of the highest concentrations of vitamin B-6 available in food. B-6 is important for adrenal health. Your adrenal glands produce important hormones, including cortisol, adrenalin, and aldosterone. Hormones produced in the adrenals help regulate blood pressure and work to control blood sugar. Salmon is rich in many other nutrients and is a great low-fat source of protein.

Salmon can be found on many restaurant menus. If you cook salmon at home, look for wild varieties. These have higher concentrations of B-6 than farmed salmon. Try experimenting with different spices and preparation techniques. Salmon can be broiled, grilled, sautéed, baked, and stir-fried. It’s delicious teriyaki-style, baked with low-sugar teriyaki sauce, sesame seeds, crushed garlic, and lime.

In cold weather, it can be made into cozy beef barley soup or stew. In warmer weather, it’s perfect for barbecues.
