B Vitamins and Pain

Why B Vitamins Matter

B vitamins play crucial roles in nerve function, energy production, and nervous system health. Deficiencies in certain B vitamins can cause or worsen neuropathy and other pain conditions. While not a pain treatment per se, ensuring adequate B vitamin status may support overall pain management.¹

Key B Vitamins for Pain²

Vitamin B12 (Cobalamin)

Essential for nerve myelin
Deficiency causes neuropathy
Numbness, tingling, burning
Common deficiency in older adults
Metformin can cause deficiency

Vitamin B1 (Thiamine)

Important for nerve function
Deficiency common in alcoholism
Can cause painful neuropathy

Vitamin B6 (Pyridoxine)

Nerve function and neurotransmitters
Deficiency can cause neuropathy
Excess can also cause neuropathy
Balance is important

Folate (B9)

Works with B12
Nervous system development
DNA synthesis

Signs of B Vitamin Deficiency³

Numbness and tingling
Burning sensations
Balance problems
Fatigue
Cognitive changes
Mood changes
Mouth sores

Who's at Risk for Deficiency

Older adults (B12)
Vegetarians/vegans (B12)
Heavy alcohol users (B1)
Gastric bypass patients
Certain medication users
Crohn's disease, celiac disease

Testing

Blood tests for B12, folate
Methylmalonic acid (MMA) more sensitive for B12
Homocysteine levels
Ask doctor if concerned

Food Sources

Meat, fish, poultry
Eggs and dairy
Fortified foods
Not naturally in plants

B1

Supplementation
