Description
"Vitamin B6" (pyridoxine) is a water-soluble vitamin found in poultry, fish, bananas, and whole grains. By converting proteins, fats, and carbohydrates into energy, pyridoxine ensures effective metabolism. Production of hydrochloric acid increases with adequate vitamin B6, promoting proper digestion and better nutrient absorption. Neurotransmitter synthesis relies on this nutrient, maintaining nerve communication and clear cognitive function. Plentiful in diverse foods, vitamin B6 deficiencies remain uncommon among those following varied and balanced dietary habits.

Deficiency Symptoms
A vitamin B6 deficiency can lead to symptoms such as peripheral neuropathy, anemia, seizures, depression, a swollen tongue, weakened immune system, cracks at the corners of the mouth, and confusion.
Synergists & Antagonists
Vitamin B6 works synergistically with vitamins A, B1, B2, B3, B5, B9, PABA, B12, C, E, and minerals like chromium, copper, iron, potassium, magnesium, manganese, sodium, phosphorus, selenium, and zinc to support energy metabolism, brain function, and immune health. However, excess calcium, copper, or iron may antagonize vitamin B6, reducing its effectiveness.

Warnings
Vitamin B6 should not be used with levodopa (L-dopa) for Parkinson's disease, as it may reduce the drug’s effectiveness. It also interacts with antibiotics, antidepressants, chemotherapy medications, phenytoin (an anti-seizure medication), and erythropoietin (used for anemia). Long-term high doses may lead to nerve damage.
Food Sources
Rich sources of vitamin B6 include nutritional yeast, whole-grain products, poultry, fish, nuts, peas, and bananas.
Time Frame
Vitamin B6 can be taken anytime, but for best results, it is recommended to take it early in the morning to support daily energy metabolism.
Depleted By
Vitamin B6 can be depleted by factors such as alcohol, antacids, corticosteroids, anticonvulsants, sedatives, bisphosphonates, nicotine, immunosuppressants, hormone replacements, hyperuricemia medications, diuretics, antidiabetic drugs, anti-cancer medications, caffeine, bronchodilators, blood pressure medications, antipsychotics, antiparasitics, antibiotics, antifungals, and antidepressants.
