What is B6 (Pyridoxine)?
B6, also known as pyridoxine, is a water-soluble B vitamin that plays a key role in numerous bodily functions. It is crucial for protein metabolism, the creation of neurotransmitters, and the production of red blood cells. B6 is also important for maintaining a healthy immune system and proper brain development and function.
Where is it Usually Found in Nature?
Pyridoxine is found in a variety of foods, both animal and plant-based. Key sources include:
- Meat and Poultry: Especially chicken, turkey, and beef.
- Fish: Such as salmon and tuna.
- Vegetables: Including potatoes, spinach, and non-citrus fruits.
- Legumes: Such as chickpeas and lentils.
- Nuts and Seeds: Particularly sunflower seeds.
- Whole Grains: Such as brown rice and fortified cereals.
- Bananas: A well-known source of vitamin B6.
Benefits to Health and Body
- Protein Metabolism: B6 is essential for the metabolism of proteins and amino acids, supporting muscle growth and repair.
- Neurotransmitter Synthesis: It plays a vital role in the production of neurotransmitters such as serotonin, dopamine, and GABA, which regulate mood, sleep, and cognitive function.
- Red Blood Cell Production: Pyridoxine aids in the production of hemoglobin, which is necessary for transporting oxygen in the blood.
- Immune System Support: B6 helps maintain a healthy immune system by supporting biochemical reactions in the immune response.
- Hormone Regulation: It assists in regulating hormones and may help alleviate symptoms of PMS and other hormonal imbalances.
Examples of Use
- Dietary Supplements: B6 supplements are used to address deficiencies, support metabolic processes, and improve cognitive function. They are available in tablets, capsules, and liquid forms.
- Energy Drinks and Bars: Many energy drinks and nutrition bars are fortified with B6 to enhance their health benefits.
- Fortified Foods: Breakfast cereals and other fortified foods often contain added pyridoxine to help ensure adequate intake.
Suggested Daily Intake
The recommended daily intake of pyridoxine varies by age and sex:
- Adult Men and Women (19-50 years): 1.3 mg per day
- Men (51 years and older): 1.7 mg per day
- Women (51 years and older): 1.5 mg per day
- Pregnant Women: 1.9 mg per day

It is important not to exceed the upper limit of 100 mg per day from supplements and fortified foods to avoid potential side effects such as nerve damage. Always consult with a healthcare provider before starting any new supplement regimen.
