Vitamin B6 (Pyridoxine)

The Vitamin B6 Blood Test measures levels of pyridoxine, a B-vitamin that helps your body process protein, make red blood cells, and keep the nervous system working properly. Low B6 can cause anaemia, irritability, confusion, or nerve problems, while healthy levels support energy, brain health, and overall wellbeing.

Vitamin B6 (Pyridoxine)

Experiencing mood changes, neurological symptoms, or immune dysfunction and want assessment of nervous system health and B6 status for optimal brain function?

Overview

Think of vitamin B6 as your brain's essential support crew, working behind the scenes to keep your mood balanced, your mind sharp, and your nervous system running smoothly. This vital nutrient acts like a master chef in your body's kitchen, helping create important brain chemicals like serotonin and dopamine that control how you feel, sleep, and think. The Vitamin B6 test measures the active form of this crucial vitamin to see if your body has enough of this neurological powerhouse to keep everything functioning optimally.

When your B6 levels drop too low, it's like having a power shortage in your brain's control center – you might experience depression, anxiety, confusion, or irritability, along with a weakened immune system and various skin problems. This test is particularly valuable if you're dealing with unexplained mood changes, neurological symptoms, or if you're taking medications that might interfere with how your body uses B6. By checking your levels, you can discover whether a simple deficiency might be behind troubling symptoms and take steps to restore your body's natural balance through proper nutrition or targeted supplementation.
