Vitamin B6 is an essential nutrient for proper body function. It's involved in multiple metabolic processes, helps regulate mood, and strengthens the immune system. Despite its importance, many people don't consume enough of it through their diet, which can lead to fatigue, irritability, or weakness.

In this article, we'll explore what vitamin B6 is, its key health benefits, and how to ensure you're getting the right amount in your diet.

What is vitamin B6 and what is it used for?

Vitamin B6, also known as pyridoxine, is a water-soluble vitamin essential for numerous physiological processes. Its main function is to participate in the metabolism of proteins, fats, and carbohydrates, ensuring that the body obtains energy from food.

Furthermore, vitamin B6 is key to the production of neurotransmitters such as serotonin and dopamine, which directly influence mood. It's also essential for the formation of hemoglobin, which helps transport oxygen in the blood.

Given its impact on so many processes, maintaining adequate levels of vitamin B6 is essential for physical and mental well-being.

Main benefits of vitamin B6

1. Improves mood and reduces stress

Vitamin B6 contributes to the production of neurotransmitters such as serotonin, dopamine, and GABA, which are essential for regulating mood. A deficiency in this vitamin can be linked to symptoms of depression, anxiety, and irritability.

Additionally, vitamin B6 supplementation has been shown to help reduce stress levels and improve sleep quality, promoting an overall sense of well-being.

2. Strengthens the immune system

The immune system depends on proper nutrition for proper functioning. Vitamin B6 is essential for the production of white blood cells, which are responsible for defending the body against infections.

A deficiency in this vitamin can weaken the immune response, making the body more vulnerable to disease and hindering recovery.

3. Promotes brain and cognitive health

The brain needs a constant supply of nutrients to stay healthy, and vitamin B6 plays a key role in its function. It contributes to the production of neurotransmitters that improve concentration, memory, and learning ability.

Some studies suggest that adequate levels of vitamin B6 may help prevent cognitive decline and reduce the risk of neurodegenerative diseases such as Alzheimer's.

4. Contributes to cardiovascular health

Vitamin B6 plays an important role in reducing levels of homocysteine, an amino acid that in high concentrations can damage arteries and increase the risk of cardiovascular disease.

By keeping homocysteine ​​under control, vitamin B6 helps protect the heart, improve circulation, and reduce blood pressure.

5. Relieves symptoms of premenstrual syndrome

Hormonal fluctuations can cause bothersome symptoms in many women before their period, such as mood swings, bloating, and fatigue.

Vitamin B6 helps regulate hormonal activity and can help reduce these symptoms, promoting greater emotional and physical balance during the menstrual cycle.

6. Improves energy production and combats fatigue

If you feel constantly tired or lack energy, your body may not be metabolizing nutrients from food properly. Vitamin B6 is essential in converting carbohydrates into glucose, providing the body with energy.

People with a deficiency in this vitamin may experience weakness, fatigue, and lack of concentration. Therefore, ensuring a sufficient intake of vitamin B6 is key to maintaining vitality throughout the day.

How much vitamin B6 do we need per day?

The recommended amount of vitamin B6 varies according to age and sex:

  • Adult men and women: 1.3-1.7 mg/day

  • Pregnant women: 1.9 mg/day

  • Breastfeeding women: 2.0 mg/day

In general, a balanced diet should provide sufficient vitamin B6. However, certain factors such as stress, pregnancy, or aging can increase the need for this nutrient.
