Hand tremors can result from various causes, including neurological disorders, medications, and nutritional deficiencies. Among vitamins, deficiencies in Vitamin B12, B6, and B1 (Thiamine) are particularly associated with tremors due to their critical roles in nerve function.

Vitamin B12 Deficiency: The Most Common Cause 

Vitamin B12 deficiency is the most commonly linked to hand tremors. This vitamin is essential for maintaining healthy nerve cells and producing DNA. A lack of B12 can lead to peripheral neuropathy, where the nerves in the hands and feet are damaged. This often results in symptoms such as tingling, numbness, balance issues, and hand tremors. Common causes of B12 deficiency include poor dietary intake (especially in vegetarians), absorption issues, or certain medications. Rich sources of B12 include animal-based products like meat, eggs, and dairy.

Vitamin B6 Deficiency: A Lesser-Known Trigger

Vitamin B6 (Pyridoxine) also plays a role in nerve health. While tremors from B6 deficiency are less common, they can still occur, particularly alongside irritability, depression, and confusion. Interestingly, both a deficiency and an overdose of B6 (usually from supplements) can lead to nerve damage. Food sources include bananas, poultry, fish, and fortified cereals.

Vitamin B1 (Thiamine) Deficiency: Often Overlooked In Chronic Alcoholism

Vitamin B1 (Thiamine) deficiency is another cause of neurological symptoms, including tremors. This is especially prevalent in individuals with chronic alcoholism or malabsorption issues. Thiamine deficiency can lead to Wernicke’s encephalopathy—a serious brain disorder characterised by confusion, coordination problems, and tremors. Whole grains, pork, and legumes are good sources of B1.

While all three vitamins, B12, B6, and B1, can contribute to tremors when deficient, Vitamin B12 deficiency is the most frequently associated with hand tremors. Early diagnosis through blood tests and timely supplementation or dietary changes can significantly improve symptoms.
