B6 Benefits

Vitamin B6: 4 Notable Benefits

What is Vitamin B6?

Vitamin B6, or pyridoxine, is an essential, water-soluble vitamin. It is a powerhouse for your body, playing several crucial roles that keep you running smoothly.

Not only does it boost brain health and enhance your mood, but it also helps with the metabolism of proteins, fats, and carbohydrates. Plus, it's vital in creating red blood cells and neurotransmitters [1].

Here's the catch: your body can't make vitamin B6 alone. You have to get it from your diet or supplements.

While most people manage to get enough B6 from their food, it's important to note that some groups, such as [pregnant women, older adults, and people with certain health conditions], are more prone to deficiency and need to be extra mindful of their intake.

Getting enough vitamin B6 is about more than avoiding deficiency. It's also vital for maintaining optimal health and could even help prevent and treat chronic diseases [2]. So, ensuring you have enough of this vitamin is a smart move for your overall well-being.

Let us discuss four notable benefits of vitamin B6.

1. Brain Health Promotion

Vitamin B6 is a true champion regarding brain health and cognitive function. Imagine it as a backstage hero in your brain's production of neurotransmitters, crucial for regulating your mood and mental functions.

Vitamin B6 acts as a cofactor in the homocysteine remethylation process. Elevated homocysteine levels can be risky, threatening cerebrovascular health and potentially harming neurons directly.

However, supplementing with B vitamins, including B6, has shown promise in reducing these levels, potentially lowering the risk of cognitive decline and Alzheimer's disease [3].

Consider this: a study involving 156 adults with high homocysteine levels and mild cognitive impairment found that high doses of B6, B12, and folate (B9) decreased homocysteine and reduced brain atrophy in regions vulnerable to Alzheimer's [4].

Adequate Vitamin B6 levels in older adults have been linked to better brain structure and function. Higher B6 intake is associated with greater gray matter volume in several brain regions crucial for cognitive function [5].

But the benefits continue beyond that. Supplementing with B6 can support brain health by reducing oxidative stress and inflammation, promoting cellular metabolism, and enhancing myelination, which is essential for efficient nerve signal transmission [6].

Vitamin B6 is also vital for brain development, particularly in synthesizing neurotransmitters and developing the central nervous system. A pregnancy deficiency can adversely affect the offspring's brain development, underscoring the importance of maintaining adequate B6 levels [7].

2. Elevating Mood and Reducing Depression

Vitamin B6 is essential for regulating mood as it helps produce neurotransmitters like serotonin, dopamine, and gamma-aminobutyric acid (GABA), which are crucial for managing emotions [8].

As we discussed before, Vitamin B6 also helps reduce high levels of homocysteine, an amino acid that's been linked to depression and other psychiatric issues [9].

Research has shown a clear connection between low blood levels of Vitamin B6 and depressive symptoms, particularly in older adults who are more susceptible to B vitamin deficiencies [10].

For example, a study involving 250 older adults found that those with low Vitamin B6 levels were twice as likely to experience depression [11]. This study highlights the importance of maintaining adequate B6 levels for mental health and overall well-being.

3. Reducing Heart-Related Diseases

Vitamin B6 might be your heart's best friend. It plays a significant role in preventing clogged arteries and reducing the risk of heart disease.

Studies have shown that individuals with low blood levels of Vitamin B6 face nearly double the risk of heart disease compared to those with higher levels [12].

This protective effect is mainly due to B6's ability to lower elevated homocysteine levels, which are linked to various diseases, including heart disease [13].

One notable study found that a Vitamin B6 deficiency led to higher cholesterol levels and the development of artery-blocking lesions when exposed to homocysteine [14].

Another compelling piece of research involved 158 healthy adults who had siblings with heart disease. They were divided into two groups: one received vitamin B6 and folic acid daily for two years, while the other received a placebo [15].

The results were striking—the group taking B6 and folic acid had lower homocysteine levels and showed fewer abnormalities in heart tests during exercise, significantly lowering their overall heart disease risk.

Keeping your Vitamin B6 levels up is a simple yet powerful way to protect your heart and enhance cardiovascular health.

4. Anemia Treatment and Prevention

Vitamin B6, a key player in hemoglobin production, is potentially effective in preventing and treating anemia caused by deficiency [16].

Hemoglobin, the protein responsible for delivering oxygen to your cells, is directly influenced by the presence of Vitamin B6.

When hemoglobin levels are low, your cells don't receive enough oxygen, leading to anemia, which often results in feelings of weakness and fatigue.

Research has shown a link between low levels of Vitamin B6 and anemia, particularly in pregnant women and women of childbearing age [17].

One compelling case study underscored the effectiveness of Vitamin B6 treatment in a 72-year-old woman with anemia due to low B6 levels [18].

The treatment with the most active form of Vitamin B6 significantly improved her symptoms, providing a reassuring testament to B6's potential in anemia treatment.

Another study found that taking 5 mg of Vitamin B6 daily during pregnancy reduced anemia symptoms in 56 pregnant women who did not respond to iron treatment [19].

These findings suggest adequate Vitamin B6 levels can prevent anemia and ensure optimal oxygen delivery to your cells, especially in populations at higher risk for deficiency.

Food Sources

You can get vitamin B6 from food or supplements.

The recommended daily amount (RDA) for B6 for adults over 19 is 1.3–1.7 mg [1].

Most healthy adults can get this amount through a balanced diet with vitamin B6-rich foods. Here are some of the best sources:

  1. Poultry:
    • Chicken breast
    • Turkey
  2. Fish:
    • Tuna
    • Salmon
    • Halibut
  3. Meat:
    • Beef liver
    • Pork
  4. Vegetables:
    • Potatoes
    • Sweet potatoes
    • Spinach
    • Peas
    • Carrots
  5. Fruits (excluding citrus):
    • Bananas
    • Avocados
  6. Legumes:
    • Chickpeas
    • Lentils
  7. Nuts and Seeds:
    • Sunflower seeds
    • Pistachios
  8. Whole Grains and Fortified Cereals:
    • Brown rice
    • Bran
  9. Dairy:
    • Milk
    • Cheese
  10. Others:
  • Soy products (like tofu)
  • Eggs


In summary, Vitamin B6 is a versatile and essential nutrient pivotal in various health aspects. Its benefits are wide-ranging and significant, from boosting brain function and regulating mood to protecting heart health and preventing anemia.

Ensuring adequate intake of Vitamin B6 through diet or supplements can help maintain optimal health and prevent a host of potential issues.

Whether you're looking to enhance cognitive function, support your cardiovascular system, or boost your overall well-being, Vitamin B6 is a crucial player worth paying attention to.
