How Vitamin and Nutrient Deficiencies Can Trigger Burning, Tingling, and Heat Sensations in the Feet
Burning feet at night can be intensely uncomfortable. The feet may feel hot, fiery, prickly, or painful—often disturbing sleep and making it hard to relax.
While this symptom is sometimes linked to nerve conditions, diabetes, or circulation issues, many people experience burning feet despite normal blood sugar and nerve tests.
In such cases, nutrient deficiencies—especially those affecting nerve function—are among the most overlooked causes.
The discomfort may affect one or both feet and often intensifies at night.
Burning sensations often intensify at night due to several factors:
The sensation of burning usually originates from irritated or undernourished nerves.
Nerves require specific vitamins and minerals to transmit signals accurately. When these nutrients are deficient, nerves may misfire—producing burning, tingling, or pain without visible injury.
Vitamin B12 is essential for nerve insulation (myelin) and signal transmission.
Low B12 commonly causes:
Symptoms can occur even with “low-normal” B12 levels.
Thiamine supports nerve energy metabolism.
Deficiency may lead to:
Low thiamine is more common with high carbohydrate intake, chronic stress, or poor absorption.
Vitamin B6 is needed for neurotransmitter and nerve function.
Both deficiency and excess B6 can cause nerve irritation, leading to burning or tingling sensations.
This makes balance—rather than high-dose supplementation—especially important.
Folate works closely with B12 in nerve repair and red blood cell formation.
Low folate can worsen nerve oxygenation and healing, contributing to burning sensations.
Vitamin D supports nerve signaling and muscle relaxation.
Deficiency has been associated with:
Magnesium calms nerve firing and supports muscle relaxation.
Low magnesium can cause:
Iron supports oxygen delivery to nerves.
When iron is low, nerves become more irritable due to reduced oxygen supply.
This can contribute to burning, aching, or restless sensations in the feet—especially at night.
Even without diabetes, unstable blood sugar can irritate nerves.
Blood sugar drops at night may worsen nerve sensations, especially in people with insulin resistance or irregular eating patterns.
Burning feet often fluctuate based on:
This variability often points toward nutritional and metabolic causes rather than permanent nerve damage.
Q: Are burning feet always a nerve disease?
A: No. Nutrient deficiencies can irritate nerves without permanent damage.
Q: Why do my feet burn only at night?
A: Nerve sensitivity increases at rest and when cortisol levels drop.
Q: Can supplements help?
A: Yes, when deficiencies are present—but balance and proper dosing are important.
Q: When should I see a doctor?
A: If symptoms are severe, progressive, or associated with weakness or numbness.
Burning feet at night are not just a sleep nuisance—they are often a sign of underlying nerve stress or nutritional depletion.
By identifying and correcting vitamin and mineral deficiencies, many people experience significant relief and improved sleep quality over time.
