Can Low Vitamin C Cause Tingling? Exploring the Link Between Nutrition and Nerve Sensations

October 20, 2025 •

4 min read

According to a 2020 study published in Nutrients, plasma vitamin C concentrations were negatively associated with tingling sensations in patients with postherpetic neuralgia, suggesting a potential link. While severe deficiency (scurvy) can lead to neurological symptoms, a simple lack of vitamin C is not typically the first suspect when investigating the root cause of tingling.

Quick Summary

Severe vitamin C deficiency can impact nerve function, potentially causing tingling, numbness, and nerve problems. This is due to the vitamin's critical role as an antioxidant and its involvement in neurotransmission and myelin formation. Other vitamin deficiencies, particularly B12, are much more common causes of tingling sensations.

Key Points

Rare Symptom: Tingling and numbness are not common symptoms of mild vitamin C deficiency but can occur in severe, long-term cases of scurvy.
Nerve Health Connection: Vitamin C's role in neurotransmission, myelin formation, and antioxidant protection is critical for proper nervous system function.
Severe Deficiency: In cases of scurvy, nerve dysfunction, including numbness and tingling, may manifest due to cellular damage and impaired function.
More Common Causes: Vitamin B12 deficiency is a much more frequent and direct cause of paresthesia (tingling/numbness) than a lack of vitamin C.
Seeking Advice: Persistent tingling should be evaluated by a healthcare professional to identify the correct underlying cause, which may include other vitamin deficiencies or medical conditions.
Dietary Role: A balanced diet rich in fruits and vegetables is the best way to prevent vitamin C deficiency and support overall nerve health.

The Crucial Role of Vitamin C in Nerve Health

Vitamin C, or ascorbic acid, is a powerful antioxidant essential for overall health, including the proper functioning of the nervous system. It is vital for a variety of neurological processes, such as the synthesis of neurotransmitters like dopamine and norepinephrine. Vitamin C also plays a critical role in the formation of myelin, the protective sheath that insulates nerve fibers and ensures efficient transmission of nerve impulses.

In the brain and nervous tissues, vitamin C is highly concentrated and helps protect against oxidative stress, which is linked to neuronal damage and neurodegenerative diseases. It does this by scavenging reactive oxygen species (ROS) produced during normal cellular metabolism. Furthermore, vitamin C helps regulate neurotransmission by preventing excessive nerve stimulation caused by glutamate, an important neurotransmitter. When levels are too low, this protective mechanism can be compromised.

Connecting Low Vitamin C to Tingling Sensations

While tingling is not a hallmark symptom of mild vitamin C deficiency, research has explored its connection to compromised nerve health. In a specific clinical study involving patients with postherpetic neuralgia, those with vitamin C deficiency were found to have a higher prevalence of tingling, prickling, and pins-and-needles sensations. The study revealed a negative correlation between plasma vitamin C levels and the severity of these symptoms. The authors hypothesized that the deficiency might be linked to increased nerve stimulation via the glutamate pathway.

Historically, severe vitamin C deficiency leading to scurvy has been documented to cause neurological issues. One account of an experimentally induced scurvy case in a 26-year-old man noted symptoms including numbness and sensitivity to touch, which resolved with vitamin C supplementation. Untreated, severe deficiency can sometimes lead to nerve problems. However, scurvy is very rare today due to widespread access to fresh produce and fortified foods.

The Role of Scurvy in Neurological Symptoms

Scurvy represents the extreme end of vitamin C deficiency. The progression of scurvy from general weakness to specific nerve issues highlights the severity of a prolonged, total lack of this nutrient. Symptoms typically appear after a few months of very low intake.

Common symptoms of scurvy include:

Fatigue and weakness
Swollen, bleeding gums
Easy bruising and bleeding under the skin (petechiae)
Joint and muscle pain
Dry, rough, or scaly skin
Anemia
Poor wound healing
Irritability

In severe, untreated cases, neurological complications like numbness, tingling (paresthesia), and convulsions can occur. The nerve-related issues can stem from a breakdown in the protective myelin sheath or damage to the nerves themselves due to impaired collagen formation and increased oxidative stress.

Comparing Causes of Tingling: Vitamin Deficiencies

When investigating the cause of persistent tingling, it is important to consider other, more common vitamin deficiencies. Vitamin B12 deficiency is a very frequent culprit and a more direct cause of nerve problems, including tingling and numbness (paresthesia), because it is essential for the production and maintenance of the myelin sheath.


Feature	Low Vitamin C	Low Vitamin B12	Low Vitamin E	Low Calcium (Hypocalcemia)
Mechanism for Tingling	Indirect association in rare severe cases or specific neurological conditions; linked to nerve stimulation and oxidative stress.	Direct involvement in myelin sheath production; deficiency can cause nerve damage.	Impairs nerve conduction by affecting nerve membranes and function.	Necessary for nerve impulse transmission; low levels can increase nerve excitability.
Other Common Symptoms	Fatigue, weakness, bruising, swollen gums, joint pain.	Fatigue, memory issues, difficulty walking, glossitis (sore tongue).	Muscle weakness, vision problems, loss of body movement coordination.	Muscle cramps, spasms, fatigue, and memory loss.
Associated Conditions	Scurvy, sometimes observed in postherpetic neuralgia.	Pernicious anemia, vegan diet, Crohn's disease, gastric surgery.	Genetic disorders, malabsorption issues.	Hypoparathyroidism, kidney disease.

Dietary and Lifestyle Considerations

For those with tingling related to a nutritional deficiency, a balanced diet rich in essential vitamins is crucial. Here are some dietary changes to consider:

For Vitamin C: Consume plenty of fresh fruits and vegetables. Excellent sources include oranges, kiwis, strawberries, bell peppers, broccoli, and kale. Low intake of fruits and vegetables is a known predictor of deficiency.
For Vitamin B12: Include animal products like meat, fish, eggs, and dairy, as well as fortified cereals and nutritional yeast.
For Vitamin E: Found in nuts, seeds, vegetable oils, and green leafy vegetables.

For those with compromised absorption or restrictive diets, supplements may be necessary. It is always best to consult a healthcare professional before starting any new supplement regimen.

When to Consult a Doctor

Experiencing persistent tingling or pins-and-needles sensations in the hands, feet, or other areas should prompt a medical evaluation to identify the underlying cause. A doctor can order blood tests to check levels of various vitamins and minerals, including vitamin C and B12, and can help rule out other potential causes. Early diagnosis and treatment of any deficiency is crucial to prevent long-term complications. In cases of severe or persistent neurological symptoms, prompt medical attention is essential.

Conclusion

So, can low vitamin C cause tingling? While research indicates a potential link, particularly in severe cases or specific neurological conditions, it's a rare cause compared to others like B12 deficiency. Vitamin C's role in nerve health is primarily protective and supportive. If you experience tingling, it's wise to consider other more common causes first, especially B12 deficiency, but a holistic nutritional assessment is always the most prudent step. Addressing any underlying dietary deficiencies through a healthy, balanced diet and, if necessary, supplementation, is key to managing and preventing nerve-related symptoms.
