Key nutrition highlights
- Withanolides: bioactive compounds standardized in quality extracts (typically 5-10%)
- Adaptogenic properties: traditionally used to support body's response to stress and maintain balance
- Extract types: KSM-66 (full-spectrum root extract) and Sensoril (root and leaf extract) are clinically studied

Typical origins & sourcing
Ashwagandha is primarily cultivated in India, the birthplace of Ayurvedic medicine. Quality sourcing considerations:
- Extract type: KSM-66 (full-spectrum root only) vs Sensoril (root + leaf)—both clinically studied
- Withanolide content: look for standardization (typically 5% for KSM-66, 10% for Sensoril)
- Indian origin: traditional cultivation regions produce highest quality
- Organic certification: reduces pesticide exposure from conventional farming
- Third-party testing: verify heavy metals, contaminants, and potency
- Root vs leaf: traditional Ayurveda uses root only; some modern extracts include leaves
Quality checklist:
- ✓ Standardized extract (KSM-66, Sensoril, or other clinically studied brand)
- ✓ Withanolide percentage clearly stated
- ✓ Third-party testing for purity and potency
- ✓ Indian origin when possible
- ✓ Organic certification preferred
- ✓ Minimal fillers or additives in capsules
- ✓ Clear dosing guidance on label

FAQ
How long does it take for ashwagandha to work?
Effects vary by individual and intended use. Some people notice stress relief within days, while optimal benefits typically emerge after 2-4 weeks of consistent daily use. Sleep improvements may take 4-6 weeks.
Should I take ashwagandha in the morning or evening?
It depends on your goals. For energy and physical performance, morning or pre-workout is common. For stress relief and sleep support, evening is preferred. Some people split doses (morning and evening). Experiment to find what works best for you.
Can I take ashwagandha long-term?
Traditional Ayurvedic use supports long-term consumption. Modern practice often suggests cycling (8 weeks on, 2 weeks off) to maintain effectiveness, though clinical studies show safety with continuous use. Consult your healthcare provider for personalized guidance.
Does ashwagandha increase testosterone?
Some studies suggest ashwagandha may support healthy testosterone levels in men, particularly in the context of stress reduction and physical training. However, it's not a primary testosterone booster. Effects are modest and most pronounced in those with stress-related hormonal imbalances.
Can ashwagandha be taken with other supplements?
Ashwagandha is generally compatible with most supplements. Common pairings include magnesium for sleep, rhodiola for energy, and L-theanine for calm focus. Avoid combining with strong sedatives without professional guidance.
