What are the health benefits of vitamin B6?

Research suggests that vitamin B6 may help prevent mood disorders, such as depression. For a quick and easy vitamin B6 fix, add a banana to your breakfast cereal. One medium banana contains almost a milligram of this nutrient. Vitamin B6 helps your body break down fats, carbohydrates, and proteins. It's also an essential part of red blood cell formation and antibody production.

The following are health benefits of vitamin B6 (pyridoxal, pyridoxine, pyridoxamine):
  • Aids in lowering homocysteine levels; not clear whether it reduces heart disease risk

Vitamin B6 plays a role in red blood cell metabolism, protein metabolism and synthesis of neurotransmitters serotonin and dopamine. It also helps maintain healthy blood sugar levels and increases the amount of oxygen carried to your tissues. Low levels can lead to an increase of homocysteine, anemia, headaches and depression. Start by eating B6 foods: bananas, chicken breast, garlic, Brussels sprouts, collard greens, sunflower seeds, broccoli, red bell peppers, watermelon, avocados and potatoes.
