Ashwagandha (Withania somnifera) is a powerful adaptogenic herb with a long history of use in Ayurvedic medicine. Native to India and parts of North Africa, it’s often called “Indian ginseng” because of its ability to support both physical and mental performance.
Modern research now confirms what traditional systems have known for centuries — this ancient remedy helps your body manage stress, supports hormone balance, and may improve energy levels, sleep quality, and overall wellbeing.
🪴 What Is Ashwagandha?
This adaptogenic shrub may be small, but its roots are mighty. The active compounds, known as withanolides, have been shown to reduce cortisol (your stress hormone), promote restful sleep, and even support testosterone and fertility in men.
It’s classified as an adaptogen, which means it helps your body respond to physical and emotional stress. People commonly use it for:
- Lowering stress and anxiety
- Improving sleep quality
- Enhancing stamina and resilience
- Supporting hormonal health
- Boosting brain clarity and focus
🔬 What the Science Says
Multiple clinical trials have shown this herbal extract can significantly reduce cortisol and improve stress levels. In one study, participants taking 300mg twice daily experienced a 44% drop in perceived stress over 60 days.
Other research highlights improvements in:
- Sleep (both falling asleep and staying asleep)
- Physical endurance, especially when used alongside training
- Mood and cognition, thanks to its impact on cortisol and inflammation
👥 Who Should Take It?
This traditional herb is generally well-tolerated and particularly helpful for people who:
- Feel overwhelmed or under chronic stress
- Struggle to get quality sleep
- Experience burnout or low energy
- Are supporting hormone balance (perimenopause, postnatal, etc.)
- Train regularly and want faster recovery
It may also support thyroid function or blood sugar control — but always consult your GP if you have a diagnosed condition or take medication.
🕰️ When & How to Take It
Ashwagandha works best when taken consistently over several weeks. It can be taken once or twice a day, with or without food.
- For sleep/stress: Take it in the evening
- For energy/focus: Morning is better
Look for extracts that clearly state withanolide content on the label (e.g. “KSM-66” or “Sensoril”). Most research-backed doses range from 250–600mg daily.
⚠️ Important: This supplement may interact with medications (especially for thyroid or blood sugar). Speak to your doctor if unsure.
🔍 What’s Really in Ashwagandha Supplements — And What’s Not?
Not all products are created equal. Many cheaper brands use diluted extracts or skip testing altogether. Here’s what to look for (and avoid):
✅ Ingredients to Look For:
- Root-only extract (not leaves)
- Standardised withanolides (ideally 5%+)
- Clean-label formulation (no synthetic fillers)
- Clinically relevant doses (250–600mg per day)
⚠️ What to Avoid:
- Proprietary blends that don’t disclose active content
- Leaf-based extracts – less researched, less potent
- Low-dose products – may offer minimal benefit
- Missing third-party testing
💡 If you’re serious about stress relief, consistent daily use is more important than high doses.
