Muscle twitching, also known as benign fasciculation, is usually benign and temporary. However, in rare cases, it can be a symptom of an underlying condition. While muscle twitching is often associated with mineral deficiencies, such as calcium or magnesium, certain medications and supplements can also cause muscle twitching. Vitamin B6 (pyridoxine) toxicity, resulting from high doses or prolonged use, has been linked to peripheral neuropathy, a type of nerve damage causing tingling, burning, or numbness, typically in the hands and feet. This can lead to muscle twitching and, in severe cases, loss of control of bodily movements. Therefore, while vitamin B is essential for nerve health, excessive amounts may contribute to muscle twitching and other neurological issues.

What You'll Learn
Vitamin B6 toxicity
While vitamin B6 is an essential nutrient and plays a role in multiple enzymatic reactions critical for the metabolism of carbohydrates, lipids, and amino acids, its consumption can sometimes result in toxicity. Vitamin B6 toxicity typically presents with peripheral neuropathy in the early stage. The most common symptoms associated with vitamin B6 toxicity are similar to those with vitamin B6 deficiency, including numbness, hyperesthesia, bone pains, muscle weakness, and fasciculations.
The only reported cases of vitamin B6 toxicity are from supratherapeutic dosing of supplements or iatrogenic. In addition to peripheral neuropathy, patients can experience ataxia, disequilibrium, dermatosis, and muscle weakness. There is no specific treatment or antidote for vitamin B6 toxicity. Treatment involves the cessation of supplemental vitamin B6, symptomatic management, and supportive care for any continued or irreversible symptoms.
It is important to note that muscle twitching can be caused by various factors, including calcium or magnesium deficiency, vitamin D deficiency, or as a side effect of certain medications and dietary supplements. In most cases, muscle twitching is temporary and may not require any treatment. However, if muscle twitching persists or is accompanied by other symptoms, it is advisable to consult a healthcare professional for proper diagnosis and treatment.

Peripheral neuropathy
Taking high levels of vitamin B6 from supplements for a year or longer can lead to severe nerve damage, resulting in a loss of control of bodily movements. This is because vitamin B6 does not simply wash out of your system in urine. Therefore, if you have a health problem that affects the levels of B6 in your body and you take supplements with a lot of B6, it can lead to B6 toxicity and cause peripheral neuropathy.
People who are taking more than one supplement may be more prone to peripheral neuropathy. It is important to check the labels of your supplements and look for the total amount of vitamin B6 you are taking each day. If you experience symptoms of peripheral neuropathy, you should stop taking the product(s) and consult a healthcare professional.
It is worth noting that peripheral neuropathy can also be caused by vitamin B12 deficiency, which can occur due to pernicious anemia, strict veganism, gastric bypass, prolonged antacid use, atrophic gastritis, or diseases of the terminal ileum.

Fasciculations
The origin of fasciculations lies in the tips of nerves, called axons, as they approach the muscle. These axons are sensitive to depolarization, which triggers muscle contraction. When a nerve fires, an electrical impulse travels towards the muscle, releasing acetylcholine, which binds to a receptor on the muscle, causing it to contract. If this process occurs involuntarily, the result is a muscle twitch or fasciculation.
It is important to note that vitamin B6 toxicity can lead to peripheral neuropathy, which may cause muscle twitching. However, this is typically associated with long-term use of supplements containing high levels of vitamin B6. In general, it is recommended to avoid taking dietary supplements unless there is a known gap in one's diet.

Muscle twitching causes
Muscle twitching, or benign fasciculation, is usually a benign issue and is rarely a cause for concern. It can occur after doing physical activity or working out, or as a result of other factors.
One potential cause of muscle twitching is vitamin deficiency. For example, a deficiency in calcium or magnesium can cause muscle twitching or spasms. A vitamin D deficiency can also cause muscle twitching, as vitamin D is necessary for the body to absorb calcium.
In some cases, taking certain medications or supplements may also lead to involuntary muscle twitching. This could be a side effect of the product, taking too much, or an interaction with other drugs. For example, taking high levels of vitamin B6 supplements for a year or longer can cause nerve damage and lead to a loss of control of bodily movements. This can manifest as peripheral neuropathy, which results in tingling, burning, or numbness, usually in the hands and feet.
Other causes of muscle twitching can include high blood levels of homocysteine, which may be addressed with vitamin B12. Constant, never-ending twitching could also be a sign of more serious conditions, such as amyotrophic lateral sclerosis (ALS), and should be assessed by a medical professional.

Muscle twitching prevention
Muscle twitching, also known as fasciculation, is usually benign and temporary, and in most cases, it goes away on its own. It is often caused by muscle fatigue, which can be triggered by vigorous or long periods of exercise. It can also be caused by a lack of sleep, stress, or too much caffeine. In addition, muscle twitching can be caused by nutritional deficiencies, such as a lack of calcium, magnesium, or vitamin D. Certain medications and supplements can also lead to muscle twitching.
To prevent muscle twitching, it is important to address the underlying causes. Here are some measures that may help:
- Manage stress and limit caffeine intake: Reducing stress and limiting caffeine can help to stop muscle twitching. Caffeine is a stimulant, and consuming too much can lead to muscle twitching anywhere in the body.
- Get adequate sleep: Sleep deprivation can cause muscle twitching. Aim for 7-9 hours of uninterrupted sleep each night to allow your body to rest and recover.
- Maintain a balanced diet: Ensure your diet includes sufficient calcium, magnesium, and vitamin D. These nutrients play vital roles in muscle function and health. Consult a healthcare professional or a registered dietician if you suspect you have a nutritional deficiency.
- Stay hydrated: Dehydration can affect the balance of electrolytes in your body, leading to muscle cramps and twitching. Drink plenty of water throughout the day to maintain proper hydration.
- Exercise appropriately: While exercise can trigger muscle twitching due to muscle fatigue, it is important to note that regular stretching and moderate exercise can help prevent muscle spasms and cramps. Avoid exercising in extreme heat, as this can further exacerbate muscle fatigue and dehydration.
- Monitor medication and supplement intake: Certain medications and supplements can lead to muscle twitching. Always read the labels and be aware of potential side effects. Consult your doctor or pharmacist if you have any concerns.
If you experience persistent muscle twitching that does not go away within two weeks or occurs in multiple places, it is important to speak with a doctor. They can help identify any underlying health conditions and develop an appropriate treatment plan.
