What Is Vitamin B6?
Pyridoxine (Vitamin B6) is an essential nutrient that plays a vital role in your body. Vitamin B6 is a water-soluble vitamin, meaning your body does not store it, so you must take it regularly. It is a booster of brain development, nervous system health, and immune function, making this vitamin essential for optimal health.
Understanding Vitamin B6
Vitamin B6 is another multitasker in your body. It is essential for energy conversion in your body from the food you consume and helps with communication between your brain and nerves by aiding neurotransmitter production. It also aids in forming hemoglobin, which is responsible for transporting oxygen through your bloodstream.
Vitamin B6 was discovered in the 1930s and was identified as a solution to some nutritional deficiencies. Through time, its value for maintaining health and preventing disease was recognized, and it rapidly became one of the most essential nutrients in the contemporary food pattern.
Vitamin B6 (also referred to as pyridoxine) is a crucial micronutrient with many proven health benefits. Vitamin B6 is an essential vitamin that is critical in maintaining physical and mental health by supporting the body’s core functions. Now, let’s dive into its proven benefits.
Boosts brain health and cognitive function
Vitamin B6 is essential for producing neurotransmitters like serotonin, dopamine, and GABA that affect mood and other cognitive processes. High vitamin intake levels have been shown to improve cognition, memory, and concentration. It may also lower your risk of neurodegeneration, which may include illnesses such as Alzheimer and Parkinson. Vitamin B6 assists in the manufacture of serotonin, which helps to alleviate depression and anxiety as well as maintain a stable, optimistic mood.
Promotes cardiovascular system health
Among all the benefits of Vitamin B6, lowering homocysteine blood levels tends to be one of the most important vitamins. Homocysteine is a recognized and established risk factor for heart disease. By controlling these levels, Vitamin B6 helps improve blood flow and lower the chances of heart attack, stroke, and other cardiovascular diseases. Thus, it is a vital part of the health of a few main systems.
Boosts Immune System Performance
Vitamin B6 plays a vital role in helping the body produce white blood cells and antibodies, both critical to combating infections and thus boosting the immune system. An efficient immune system means fighting off viral and bacterial infections more robustly and returning from sickness faster. It is essential for people with impaired immune systems and chronic inflammation.
Relieves Symptoms of Premenstrual Syndrome
Premenstrual syndrome (PMS) can be a distressing time for women with mood swings, tiredness, and pain. Vitamin B6, which reduces these symptoms. It produces serotonin, which helps to stabilize mood and reduce irritability. A diet high in Vitamin B6 or specific supplementation can relieve PMS pain and discomfort for many women.
Vitamin B6 is also vital for producing hemoglobin, the protein in red blood cells that transports oxygen throughout the body. This function also helps to keep energy in the body and prevent anemia. One of the main symptoms of vitamin B6 deficiency is fatigue, and restoring this nutrient often alleviates any lingering fatigue.
Vitamin B6 aids protein metabolism, which is essential for skin and hair health. This action maintains skin elasticity and hydration and avoids dandruff, dryness, and irritation. Those with eczema, acne, etc., may benefit from taking vitamin B6 regularly.
Helps Ease Morning Sickness During Pregnancy
Vitamin B6 supplementation decreases the severity of morning sickness, a common problem during the first trimester in pregnant women. So far, research has proven it to be a safe and effective treatment for nausea and vomiting, giving relief to mothers to be without harming their developing babies.
Lastly, vitamin B6 is indispensable for producing and regulating hormones; hence, it can be beneficial in treating many hormone-based diseases. Vitamin B6 supports women with polycystic ovary syndrome (PCOS) and those experiencing menopause (irregular cycles, hot flashes, mood changes).
Helps in the Prevention From Chronic Disease
After a couple of years of vitamin consumption, the presence of Vitamin B6 in your daily diet can help reduce the risk of chronic diseases like cancer and type 2 diabetes. Studies show it contributes to less inflammation, a significant factor in many lifestyle diseases. The consumption of Vitamin B6 has been correlated with a lower risk of colorectal and breast cancers.
Helps with carpal tunnel syndrome symptoms
Vitamin B6 has been shown to help in carpal tunnel syndrome, where there is pain/tingling feeling in the hands/wrists because it is responsible for nerve function. When taken regularly, it normalizes discomfort and can ultimately strengthen nerve health for those suffering from this disease.
Alleviation from exhaustion and improved mood
Vitamin B6 is essential in converting foods into energy, helping reduce fatigue and maintain consistent energy levels throughout the day. It also helps with the production of serotonin, which is directly responsible for improving your mood and lowering irritability. Due to these combined effects, this would be the right way to increase mental and physical endurance.
Evidence also shows that Vitamin B6 protects against age-related macular degeneration, which is also a primary cause of vision loss in older adults. Its anti-inflammatory effects boost eye health by protecting retinal cells from damaging processes and improving vision in midlife and older age.
The B6 vitamin is involved in many processes within our body, such as metabolism, brain health, and immune system support. The good news is that many foods offer high levels of Vitamin B6, making it easy to include daily. Below is a summary of the different leading sources.
Chicken, as well as turkey, are one of the best sources of vitamin B6. The recommended dietary allowance of Vitamin B6 is 1.3 mg for adults, and you can expect to get roughly 30% of that amount from a 3-ounce serving of chicken breast. Lean protein sources also help keep your muscles healthy and boost energy metabolism.
Fish: Salmon, Tuna, and Other Fatty Fish
Salmon and tuna are two of the fatty fish loads with Vitamin B6. Salmon (3 oz. cooked): ~0.5 mg B6; about 1/3 of your daily requirement. They’re also an excellent source of heart-healthy omega-3 fatty acids.
Sweet potatoes specialize in Vitamin B6 and are part of the broader vegetation family that supplies this essential nutrient. A medium sweet potato contains ~0.3 mg of vitamin B6, about 15–20% daily (67). High in fiber and beta-carotene, they help support eye and immune function.
A quick snack most individuals may find timely and delightful is bananas, which provide vitamin B6. Provided you get enough from other sources, a medium-sized banana has approximately 0.4 mg of vitamin B6 and around 20% of the recommended daily allowance. Bananas also provide potassium and dietary fiber to aid in heart and digestion health.
Many breakfast cereals should be fortified with Vitamin B6, so it’s easy to meet your daily requirements. One serving or less of some cereals can provide nearly as much as 100% of the daily recommended amount. Milk or yogurt can increase vitamin B6 absorption when in conjunction with cereal.

Vitamin B6, known as pyridoxine, is crucial for several bodily processes like brain health, immune function, and metabolism. Lack of this vitamin may cause several health problems. Common signs of vitamin B6 deficiency:
Fatigue is one of the most common signs of vitamin B6 deficiency. Vitamin B6 is essential to energy production, so its deficiency might result in fatigue, malaise, or lethargy.
Vitamin B6 aids in producing neurotransmitters such as serotonin and dopamine, which manage your mood. However, mood swings and emotional instability are often accompanied by irritability, anxiety, and depression due to the deficiency of Vitamin B6.
In addition, vitamin B6 deficiency can lead to skin problems such as a rash, cracking of the lips and mouth, and seborrheic dermatitis. Inflamed and dry skin can also increase the risk of infections.
Peripheral neuropathy: A deficiency in Vitamin B6, essential for nerve function, may lead to peripheral neuropathy—a disorder that can produce numbness, tingling, or pain in the hands and feet. As a result, coordination and balance become problematic.
Vitamin B6 is involved in the formation of red blood cells. Not having enough can cause anemia, pale skin, dizziness, shortness of breath, and fatigue.
Vitamin B6, which supports cognitive function. Lack of vitamin B6 can cause an inability to remember things, problems in concentration, and other symptoms like brain fog. This can be confusing or cognitive downtime in the most acute cases.
Sore, Swollen Tongue (Glossitis)
Glossitis, a period-inflammatory inflammatory condition of the tongue, is associated with a lack of vitamin B6. This condition can cause the tongue to be painful, red, and smooth, making eating and speaking very uncomfortable.
Vitamin B6 helps maintain a robust immune system. Weakened immune system: A deficiency can weaken your body, making fighting infections and illnesses harder.
You can have irregular heartbeats or palpitations if vitamin B6 is lacking in your body. However, that is mainly because Vitamin B6 is partly responsible for regulating levels of an amino acid (homocysteine) that affects cardiovascular health.
Another sign may be swelling in the extremities (hands and feet), which can also be a lack of Vitamin B6. B6 aids in maintaining essential fluid levels throughout the body.
They are at increased risk of deficiency in people with kidney disease, alcohol dependency, or some autoimmune conditions. It may also be an issue for those on restrictive diets.
Effect of Chronic Insufficiency on Health
Long-term deficiency can result in severe medical issues such as anemia, depression, and a susceptible immune system.
Vitamin B6 (pyridoxine) is required in every body process. Its guidelines for use are so specific that they differ by gender, life stage, and even age range to ensure the best possible health. These guidelines were issued as part of the Dietary Reference Intakes (DRIs) by the Food and Nutrition Board (FNB).
DRI establishes a range of amounts of each nutrient you should take. These reference values are used to develop and assess the diets of healthy people. There are four major categories of DRIs for vitamin B6:
- Recommended Dietary Allowance (RDA): This value is the average daily dietary intake of a nutrient sufficient to meet the requirements of nearly all (97%–98%) healthy individuals. It is the most widely used guideline for setting dietary standards and planning nutritionally adequate diets.
- Adequate Intake (AI): An AI level can be established when evidence is insufficient to formulate an RDA. It is mandated to guarantee nutritional sufficiency.
- Estimated Average Requirement (EAR): The average daily intake estimated to meet the needs of half of healthy people. It is most often used to assess the nutrient consumption of groups and to set dietary requirements for populations.
- Tolerable Upper Intake Level (UL): The UL is the maximum daily nutrient intake unlikely to cause adverse health effects in the general population—an important marker to prevent toxicity from over-supplementation.
Dietary Reference Intakes (DRIs) for Vitamin B6
The RDAs depend on the age, sex, and physiological conditions like pregnancy or lactation. Here’s how you get there in detail:
Infants
- 0.1 mg/day (AI based on mean intake from breast milk) Birth to 6 months.
- 7–12 months: 0.3 mg/day (AI).
Children
- 1–3 years: 0.5 mg/day.
- 4–8 years: 0.6 mg/day.
Adolescents
- 9–13 years: 1.0 mg/day, boys and girls.
- 14–18 years: Males: 1.3 mg/day, Females: 1.2 mg/day.
Adults
- 19 to 50 years: for men, 1.3 mg/day, and for women, 1.3 mg/day.
- 51+ years: Males: 1.7 mg/day, Females: 1.5 mg/day.
Pregnancy and Lactation
Pregnancy:
- Ages 14–18: 1.9 mg/day.
- Ages 19–50: 1.9 mg/day.
Lactation:
- Ages 14–18: 2.0 mg/day.
- Ages 19–50: 2.0 mg/day.
