Ashwagandha Side Effects: What You Need to Know

Ashwagandha (Withania somnifera) is a popular adaptogenic herb used in Ayurvedic medicine for centuries. It’s gaining traction in Western wellness circles for its potential to reduce stress, improve sleep, and boost cognitive function. However, like any supplement, ashwagandha isn’t without potential side effects. This article details what you need to know.

Common Side Effects

Generally, ashwagandha is considered safe for most people when taken in recommended doses for short periods (typically up to 6 months). However, some individuals may experience:

• Digestive Issues: This is perhaps the most frequently reported side effect. It can include nausea, vomiting, diarrhea, and stomach upset. Starting with a low dose and gradually increasing it can help minimize these issues.
• Drowsiness: Ashwagandha has calming properties, which can lead to drowsiness, especially at higher doses. Avoid operating heavy machinery or driving if you experience this.
• Headache: Some users report mild headaches, particularly when first starting supplementation.
• Lowered Blood Sugar: Ashwagandha may lower blood sugar levels. This can be beneficial for some, but problematic for individuals with diabetes or hypoglycemia.

Less Common, But Serious Side Effects

While rare, these side effects require immediate attention:

• Liver Problems: There have been reports of liver damage (drug-induced liver injury) associated with ashwagandha use. Symptoms include jaundice (yellowing of the skin or eyes), dark urine, and abdominal pain. Discontinue use immediately and consult a doctor.
• Thyroid Issues: Ashwagandha can stimulate thyroid hormone production. This can be problematic for individuals with hyperthyroidism (overactive thyroid).
• Autoimmune Reactions: Because ashwagandha boosts the immune system, it may worsen symptoms in people with autoimmune diseases like rheumatoid arthritis, lupus, or multiple sclerosis.

Who Should Avoid Ashwagandha?

Certain groups should exercise caution or avoid ashwagandha altogether:

• Pregnant and Breastfeeding Women: There isn’t enough research to confirm its safety during pregnancy or breastfeeding.
• Individuals with Thyroid Disorders: Especially those with hyperthyroidism.
• People with Autoimmune Diseases: Due to potential immune system stimulation.
• Those Taking Immunosuppressants: Ashwagandha may interfere with these medications.
• Individuals Scheduled for Surgery: Ashwagandha may affect blood sugar and blood pressure, potentially impacting surgical outcomes.

Drug Interactions

Ashwagandha can interact with several medications, including:

• Sedatives: May enhance the effects of sedatives, leading to excessive drowsiness.
• Immunosuppressants: May reduce the effectiveness of these drugs.
• Diabetes Medications: May cause blood sugar to drop too low.
• Blood Pressure Medications: May cause blood pressure to drop too low.

Important Considerations

Dosage: Follow the dosage instructions on the product label or as directed by a healthcare professional. Start with a low dose and gradually increase it as tolerated.

Quality: Choose reputable brands that undergo third-party testing to ensure purity and potency.

Consult Your Doctor: Always talk to your doctor before starting any new supplement, especially if you have underlying health conditions or are taking medications.
