Can Ashwagandha Cause Anxiety in Some People?

Can ashwagandha cause anxiety? Although many people take it for stress, some may develop nervousness, restlessness, palpitations, poor sleep, or anxiety-like feelings after using it. These symptoms are often temporary and may relate to the product, dose, other substances, or an underlying health issue, but persistent or severe symptoms should be assessed by a clinician.

Can Ashwagandha Cause Anxiety?

Yes. Ashwagandha can cause anxiety or anxiety-like symptoms in a small number of people, even though it is more often marketed as a supplement for stress and sleep. New feelings of nervousness, inner restlessness, irritability, shakiness, rapid heartbeat, or difficulty sleeping may occur after starting it or changing products. In many cases, symptoms are mild and improve after the supplement is stopped.

Not every uncomfortable feeling after taking ashwagandha is caused by the herb itself. Stress, caffeine, illness, poor sleep, alcohol, recreational drugs, medicines, and an existing anxiety condition can all contribute. It is still important to take a new symptom seriously, especially when it is intense, persists, or occurs with physical warning signs.

Ashwagandha products vary widely. They may contain different parts of the plant, different extract concentrations, or additional ingredients. Because supplements are not standardized in the same way as prescription medicines, the effect of one product may not predict the effect of another.

Why Anxiety-Like Symptoms May Happen

The exact way ashwagandha affects mood and alertness is not fully understood. It may influence stress-response pathways and brain signaling chemicals, but research on its mental health effects remains limited and products used in studies are not always the same as those sold commercially. A person’s individual sensitivity can therefore make a meaningful difference.

Some people experience side effects that resemble anxiety rather than anxiety itself. For example, sleep disruption can lead to next-day tension and irritability. Nausea, abdominal discomfort, dizziness, sweating, tremor, or awareness of the heartbeat may also be interpreted as a panic-like response, particularly in someone already worried about their health.

In some cases, ashwagandha may affect thyroid activity. An overactive thyroid can cause symptoms including anxiety, heat intolerance, tremor, palpitations, weight changes, and sleep difficulties. This does not mean that every person with symptoms has a thyroid problem, but it is one reason clinicians may consider blood testing when symptoms do not settle.

Factors That Can Increase the Chance of Symptoms

Symptoms may be more likely after beginning a new supplement, taking a larger amount than before, or switching to a more concentrated extract. Taking several products marketed for energy, stress, weight management, or exercise at the same time can make it difficult to identify what is causing a reaction. Some combination products contain stimulants or other herbs that may worsen jitteriness or sleep problems.

Caffeine from coffee, tea, energy drinks, pre-workout products, or certain cold medicines can amplify a racing heart, shaking, and anxious feelings. Alcohol and poor sleep may have similar effects. For this reason, looking at the timing of symptoms in relation to all supplements, medicines, food, drink, and lifestyle changes can be useful.

People with thyroid disease, autoimmune conditions, liver disease, hormone-sensitive conditions, or a history of severe anxiety, panic episodes, bipolar disorder, or psychosis should speak with a clinician before using ashwagandha. It may also interact with medicines that affect blood sugar, blood pressure, immunity, thyroid function, sedation, or mental health.

• Do not assume that “natural” means risk-free or suitable for every person.
• Tell a clinician and pharmacist about all prescription medicines, over-the-counter products, vitamins, and herbal supplements.
• Pregnant or breastfeeding people should seek individualized medical advice before using herbal supplements.

How to Tell Whether Ashwagandha Is Involved

A useful first clue is timing. Anxiety-like symptoms that begin soon after starting ashwagandha, increasing the amount, or using a new brand may be related to the supplement. A symptom diary can help: record when the supplement was taken, the product name, other medicines or substances used, sleep quality, meals, caffeine intake, and the type and timing of symptoms.

It is generally reasonable to stop a non-prescribed supplement if it appears to be causing new symptoms, unless a clinician has advised otherwise. Avoid trying to “push through” significant anxiety, palpitations, or insomnia by adding more supplements or sedatives. It is also best not to restart the product without discussing the reaction with a qualified healthcare professional.

A doctor will consider other explanations as well. They may ask about recent life stressors, panic symptoms, mood changes, sleep, stimulant use, alcohol and substance use, medical history, and family history. Depending on the symptoms, an examination and tests such as thyroid function testing, blood counts, glucose testing, or an electrocardiogram may be appropriate.

What to Do If Symptoms Start

If symptoms are mild, stopping ashwagandha and reducing other possible triggers, such as caffeine and energy products, may help. Maintaining regular meals, hydration, gentle physical activity, and a consistent sleep routine can support recovery while the body settles. Slow breathing exercises or grounding techniques may also reduce the physical intensity of temporary anxiety.

However, it is important not to self-diagnose persistent symptoms as simply a supplement reaction. Anxiety can be a treatable health condition, and physical symptoms may occasionally point to a thyroid, heart rhythm, medication, or other medical concern. Information about anxiety-related symptoms may also be helpful in the context of anxiety disorders.

Anyone taking prescription medication should contact the clinician who prescribed it or a pharmacist before making changes. Ashwagandha should not be used to replace evidence-based treatment for anxiety, depression, thyroid disease, or sleep problems. A care plan may include psychological support, lifestyle measures, and, when appropriate, medical treatment tailored to the individual.

When to Seek Medical Care

Arrange a medical review promptly if anxiety, agitation, panic-like episodes, insomnia, tremor, or palpitations continue after stopping ashwagandha, interfere with daily life, or become progressively worse. A review is also important if symptoms occur in someone with thyroid disease, a significant mental health history, or regular use of medicines that may interact with supplements.

Seek urgent medical care for chest pain, severe shortness of breath, fainting, confusion, a sustained or very irregular heartbeat, severe vomiting, yellowing of the eyes or skin, or signs of a serious allergic reaction such as facial swelling or difficulty breathing. Emergency support is also needed for thoughts of self-harm, suicidal thoughts, or feeling unable to stay safe.

For international patients, Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals can assess new anxiety-like symptoms and possible medication or supplement-related concerns. Bringing the supplement container or a clear photograph of its ingredients can help the clinical team assess the product.

Safer Supplement Decisions Going Forward

Before starting any herbal supplement, it is sensible to discuss the goal with a doctor or pharmacist. This is especially important when a person has a long-term condition, takes regular medicines, is preparing for surgery, or has previously had a reaction to a supplement. A clinician can help determine whether symptoms such as stress, fatigue, poor sleep, or low mood may have an underlying cause that deserves assessment.

If a supplement is considered appropriate, choose a product with clear labeling and avoid products that make dramatic claims. Use only one new supplement at a time so that any reaction is easier to recognize. Following the label directions does not eliminate the risk of side effects, and a person should stop and seek advice if troubling symptoms develop.

For many people, proven approaches to stress management are more reliable than herbal products. These can include regular sleep, physical activity suited to the individual, limiting caffeine, supportive relationships, relaxation practices, and structured mental health care when needed. Persistent anxiety deserves compassionate clinical attention rather than self-treatment alone.

Frequently asked questions

Can ashwagandha make anxiety worse?

It can make anxiety worse or cause anxiety-like symptoms in some people. Restlessness, poor sleep, tremor, nausea, and a fast heartbeat may all increase distress. If symptoms started after beginning ashwagandha, stopping it and discussing the reaction with a clinician is sensible.

How long does anxiety from ashwagandha last?

The duration varies depending on the product, amount taken, individual sensitivity, and whether other substances or medical conditions are involved. Mild symptoms may improve after the supplement is stopped, but persistent or worsening symptoms should be medically assessed. A doctor can also check for another cause, such as thyroid dysfunction or medication effects.

Can ashwagandha cause panic attacks?

Ashwagandha has not been established as a direct cause of panic disorder, but it may produce sensations such as palpitations, shakiness, dizziness, or insomnia that can feel like or trigger a panic attack in a susceptible person. A new or severe panic-like episode should not be ignored. Medical advice is particularly important if there is chest pain, fainting, breathing difficulty, or safety concerns.

Should a person stop taking ashwagandha if they feel anxious?

For new anxiety-like symptoms linked to a non-prescribed ashwagandha supplement, stopping the product is generally a prudent step. The person should avoid taking more to test whether the symptoms improve. Anyone using prescription medicines or managing a chronic condition should also contact a clinician or pharmacist for individualized advice.

Can ashwagandha affect the thyroid?

Ashwagandha may affect thyroid hormone activity in some people. Symptoms of excess thyroid activity can include anxiety, palpitations, sweating, tremor, heat intolerance, and trouble sleeping. People with thyroid disease or these symptoms should seek medical advice before continuing the supplement.

What medicines can interact with ashwagandha?

Ashwagandha may interact with medicines that affect thyroid function, blood sugar, blood pressure, immune activity, or sedation, among others. The risk depends on the individual medicine and health condition. A pharmacist or doctor can review all medicines and supplements together to identify possible concerns.
