Known as one of the most important herbs in Ayurveda, Ashwagandha (Withania somnifera) is an adaptogen that has been used for over 3,000 years to support stress relief, energy and concentration.

Key Benefits

• Stress support: Traditionally used to help the body adapt to stress and promote a sense of calm.
• Better sleep: Often taken at night to support restful sleep.
• Strength and stamina: Supports muscle strength and recovery when combined with regular exercise.

Dosage Guidelines

Ashwagandha root extract is commonly taken in the range of 300–500 mg per day, but the right dose depends on the product and the person. Follow the dose on the pack or your practitioner’s advice. It can be taken with warm water or milk, at night to support sleep or in the morning for daily stress.

Side Effects and Precautions

Ashwagandha is generally well tolerated. Taking too much can cause mild stomach upset or loose motions. Avoid it during pregnancy, and consult a doctor first if you have thyroid problems, an autoimmune condition (such as lupus or rheumatoid arthritis), or take sedatives, thyroid or blood-pressure medicines.
