Tremors vary in type and cause. From Parkinson’s tremors to Essential Tremors, there are many factors to consider when building a treatment plan, depending on symptoms, severity, and underlying health conditions. If you’re experiencing internal tremors at night, during the day, or in general, you might wonder not only “What is the best medicine for tremors?” but also whether certain vitamins for tremors or supplements for tremors can help. While some tremors cannot be cured, many nutrients support nerve and muscle health and may reduce the risk for hand–shaking–related concerns.
First of All, What Causes Tremors?
Internal tremors can result from conditions that affect the central nervous system, such as Parkinson's Disease, Eessential Tremor, or multiple sclerosis. They may also be triggered by cerebellar problems, low blood sugar, or side effects of certain medications. Lifestyle factors like high caffeine intake, alcohol withdrawal, anxiety, and stress can also play a role. Because tremors can stem from multiple sources, it’s important to seek medical advice before starting any new treatment or adding supplements for tremors.
What Are the Best Vitamins and Supplements for Tremors?
One common factor in many “How I managed my tremors” stories is the use of targeted vitamins and supplements. If you’ve asked yourself, “What is the best vitamin for essential tremors?” here are some evidence-backed nutrients to consider:
Vitamin B12
Vitamin B12 supports nerve health by helping create myelin, the protective sheath around nerve fibers. A deficiency in B12 can cause numbness, weakness, fatigue, and shaking hands. In fact, what vitamin deficiency causes shaking hands? — B12 is one of the most common culprits.
Vitamin D
Known as the sunshine vitamin, Vitamin D is vital for bone strength, nerve health, and muscle contraction. Low levels can lead to weakness, pain, and increased risk of tremors. Ensuring adequate Vitamin D intake is one of the simplest ways to incorporate it into your routine.
Vitamin B6
Vitamin B6 plays a role in neurotransmitter production, supporting the balance of dopamine and serotonin. A deficiency may result in tingling, limb pain, and tremors, such as right-hand shakes when holding objects.
Vitamin E
Vitamin E is a strong antioxidant that protects nerve cells from oxidative damage. Though deficiencies are rare, they can cause neuropathy and body tremors.

Other Helpful Supplements for Tremors
Magnesium
Magnesium helps relax muscles and regulate nerve transmission. Many people with essential tremor are advised to take magnesium as one of the more effective supplements for tremors.
Calcium
Calcium is essential for nerve signaling and muscle contraction. Severe calcium deficiency (hypocalcemia) can disrupt neuromuscular function, leading to cramps, spasms, twitching, and increased nerve excitability—symptoms that some people may describe as trembling.
Omega-3 Fatty Acids
Omega-3 fatty acids, found in fatty fish, walnuts, and flaxseeds, are essential for nervous system health and have anti-inflammatory and neuroprotective roles. While they support overall nerve function, there is not conclusive evidence that omega-3s directly reduce tremor severity.
Alpha-Lipoic Acid (ALA)
ALA is a powerful antioxidant that protects nerve cells and promotes mitochondrial energy production.

Recommended Dosages & RDA Values For Tremor-Related Vitamins And Supplements
When exploring vitamins and supplements for tremor support, one of the most common questions is: “How much should I take?” Understanding Recommended Dietary Allowances (RDAs) and safe intake ranges is essential, as more is not always better.
RDAs represent the average daily intake sufficient to meet the nutritional needs of most healthy individuals. In some cases—such as nutrient deficiencies, absorption issues, or increased physiological needs—healthcare providers may recommend higher doses under supervision.
Below is an overview of the vitamins and minerals commonly discussed in tremor management, including RDAs and commonly used supplemental ranges. These values are for general educational purposes and are not tremor-specific treatment recommendations.
Vitamin B12
-
RDA: 2.4 mcg per day (adults)
-
Common Supplement Ranges: 500–2,000 mcg daily (often used when deficiency or absorption issues are present)
-
Notes: Absorption decreases with age (especially 50+). Some individuals require injections or sublingual forms. Excess B12 is generally excreted, but supplementation should be guided by blood testing.
Vitamin D
-
RDA:
-
600 IU/day (ages 19–70)
-
800 IU/day (ages 71+)
-
Notes: No established tremor-specific dose. Vitamin D deficiency is common and associated with neuromuscular symptoms. Blood testing is recommended before high-dose supplementation.
Magnesium
-
RDA:
-
310–320 mg/day (adult women)
-
400–420 mg/day (adult men)
-
Notes: Magnesium supports nerve and muscle function. Excess supplementation can cause gastrointestinal side effects. Forms such as magnesium glycinate or citrate are often better tolerated.
Calcium
-
RDA:
-
1,000 mg/day (adults 19–50)
-
1,200 mg/day (women 51+, men 71+)
-
Notes: Calcium is essential for nerve signaling and muscle contraction. Intake includes both dietary and supplemental sources. Excess calcium should be avoided without medical guidance.
Omega-3 Fatty Acids
-
RDA: No established RDA
-
Common Supplement Ranges: 1,000–3,000 mg/day combined EPA/DHA
-
Notes: Supports brain and nerve health. High doses may interact with blood-thinning medications.
Vitamin E
-
RDA: 15 mg/day (22.4 IU)
-
Upper Intake Limit: ~1,000 IU/day
-
Notes: High doses may increase the risk of bleeding. Supplement cautiously and avoid megadoses unless medically indicated.
Vitamin B6
-
RDA:
-
1.3 mg/day (adults 19–50)
-
1.5–1.7 mg/day (older adults)
-
Notes: Chronic high doses may cause nerve damage. Avoid exceeding recommended limits unless advised by a clinician.
Alpha-Lipoic Acid (ALA)
-
RDA: None established
-
Common Supplement Ranges: 300–600 mg/day
-
Notes: Often used for neuropathy support. It can affect blood sugar levels.
Upper Intake Limits & Safety
Many vitamins and minerals have upper intake limits (ULs), beyond which toxicity or adverse effects may occur. This is especially important for fat-soluble vitamins (A, D, E, and K) and for minerals such as calcium and magnesium.
Special Populations
Supplement needs may differ for:
-
Adults over 50 (reduced absorption)
-
Vegans and vegetarians (B12 risk)
-
Pregnant or breastfeeding individuals
-
People taking medications that affect absorption
Always consult a healthcare provider before starting or adjusting supplement dosages, especially if tremors are present.
