Can low b12 cause tremors?

It’s no secret that vitamin deficiencies can wreak havoc on the body, but could low levels of vitamin B12 be causing tremors? In this article, we’ll dive into the world of B vitamins and explore whether a lack of B12 is behind those shaky hands.

Understanding Vitamin B12

To begin our investigation, it’s essential to have a basic understanding of what vitamin B12 does in the body. Vitamin B12, also known as cobalamin, plays a vital role in DNA synthesis and cell metabolism. It’s required for nerve function and red blood cell production.

The human body cannot produce vitamin B12 on its own; it must be obtained from dietary sources or supplements. Some of the most common sources include meat, poultry, milk products such as cheese and yogurt as well as fortified breakfast cereals.

Although relatively uncommon in developed countries due to widely available diets[], deficiency can occur if someone has pernicious anemia where they cannot absorb enough b-12 or if their diet lacks adequate amounts []. Deficiencies often go unrecognized until severe symptoms start to surface.

What Are Tremors?

Before delving further into how low levels of vitamin B12 may cause tremors let’s first take some time to understand exactly what tremors are.

Tremor refers to involuntary trembling movements that affect different parts of your body []. Typically these are considered benign essential tremor (BET) when shakiness is concentrated either bilaterally symmetrically involving both sides at once or solely upon one side (unilateral) usually only noticeable when limbs rest against gravity such as arms held outstretched horizontally showing up more so at times anxiety ramps up or drink coffee [].

While it’s natural for muscles’ fine adjustments responsible for small movements like holding your hand steady while drinking tea under normal conditions other types like Parkinsonian Tremor caused due to Parkinson’s disease, a neurological disorder that affects motor control [].

How Does B12 Deficiency Affect Tremors?

Tremors can be a symptom of many conditions other than vitamin B12 deficiency, but some studies suggest that low levels of this nutrient in the body can cause shaking. So now let’s explore further.

Vitamin B12 is necessary for proper nerve function; a shortage of it in the body could lead to nerve damage or degeneration over time []. In nerves that control muscle movement known as motor neurons where they receive and transmit information from your brain When these are damaged or start dying, it may result in tremors[].

While further researches must be conducted – one such study published in the Journal of Clinical Neurology found that three elderly patients who had trembling limbs experienced resolution after treatment with Vitamin-B12 injections pointed towards BET was part or wholly resulting from cobalamin deficiency [].

B twelve/ Cobalamin deficiencies often go unrecognized until severe symptoms occur. However still if we remain vigilant below we list out certain signs which might give us an indication:

  • Fatigue
  • Weakness
  • Dizziness
  • Pale skin caused by anemia (low red blood cell count)
  • Numbness and tingling sensations
  • Loss of balance while walking

The items marked ” above would hold importance when investigating poorer nerve conduction regarding tremorous body parts.

It is crucial to get early diagnosis upon onset; delays may attest significant physical changes due to prolonged deficiencies. Getting diagnosed follows:

1) Visit Certified Medical Practitioner: If you’re experiencing any Tremors regularly, make sure you visit your doctor so they will have available health history afterward run tests like CBC(Complete Blood Count).
2) Serum MMA Test: This measure MMA stands for methylmalonic acid more excess means significantly likely b-12 deficient.
3) Homocysteine Levels: In this case, if the homocysteine level is elevated in your blood, it might indicate a deficiency too [].


Whether B-12 related tremors or not , Tremor Severity would have to be adjusted with subsequent medication prescribed by a qualified medical practitioner.
1) Vitamin Replacement Tablets: Efficient way of correcting deficiencies; Some treatments include taking supplements specifically designed for cobalamin efficiency such as high-dose oral b-12 pills where patient given appropriate dosage combined folic acid and vitamin b group towards rebuilding red-blood cell movements likewise tremorous systems’ reverberations eventually calming down some [].
2) B-12 injections: Patients who can’t absorb enough orally due to an inability to produce intrinsic factor commonly caused by autoimmune diseases like pernicious anemia may require intramuscular injections done on muscles within thighs respective arms ad administer cobalamins directly into the bloodstream. Any number between 5 and 10 doses spread over several weeks or months can help mitigate effects[

While low levels of vitamin B12 do cause nerve damage, which could lead to tremors being one symptom resulting from that degree though unrelated factors cannot be ruled out, so make sure you meet your doctor for advice on what’s ideal for your health condition.

The best course of action depends on exactly why someone’s experiencing any given set of symptoms., Despite bearing resemblance amongst many different illnesses makes pinpointing harder at times only professional insight could bear fruit via necessary testing data performed accordingly no conspiracy needed here!
