Your Vitamin B6 Level

What Causes Abnormal Vitamin B6 Levels?

To successfully treat and prevent recurrence of abnormal vitamin B6 levels we need to understand and — if possible — remove the underlying causes and risk factors.  We need to ask: "What else is going on inside the body that might allow abnormal vitamin B6 levels to develop?"

Accurate diagnosis of the factors behind abnormal vitamin B6 levels consists of three steps:

Step 1: List the Possible Causative Factors

Identify all disease conditions, lifestyle choices and environmental risk factors that can lead to abnormal vitamin B6 levels.  Here are two possibilities:
  • Nutritional Deficiency Anemia
  • Pyroluria

Step 2: Build a Symptom Checklist

Identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
rapid sunburn tendency
small social support group size
lighter/paler skin color
being a recovered alcoholic
minor joint pain/swelling/stiffness
frequent unexplained nausea
being prone to 'stitches'
severe fatigue after slight exertion
no desire to eat breakfast
high sensitivity to bright light
being an unsocial person
forgetting dreams
... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of abnormal vitamin B6 levels:
Cause Probability Status
Nutritional Deficiency Anemia 94% Confirm
Pyroluria 55% Possible
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate having had recent lab tests, The Analyst™ will ask further questions including this one:
Vitamin B6 (pyridoxine). Unit: ng/mL [nmol/L]
Possible responses:
→ Don't know
→ Confirmed deficiency in the past
→ Under 4 [16] (low)
→ 4 to 18 [16-73] (normal)
→ Over 18 [73] (elevated)
Based on your response to this question, which may indicate history of B6 deficiency, low B6 levels, normal B6 levels or high B6 levels, The Analyst™ will consider possibilities such as:
Pyroluria

A functional pyridoxine deficiency is common in pyroluria (often seen in alcoholics), due not so much to inadequate intake as impaired conversion to its active form, pyridoxal-5-phosphate, and enhanced degradation.
