🌿 What is Ashwagandha?
Ashwagandha (Withania somnifera) is an ancient adaptogenic herb used in Ayurvedic medicine for thousands of years. Modern clinical research backs it up — it's one of the most studied supplements for reducing cortisol (stress hormone), improving sleep quality, boosting testosterone, and supporting athletic recovery. The key is the extract type and dosage.

📏 Dosage Guide
What's the right ashwagandha dose?
For KSM-66: 300–600mg per day is the clinically studied range. Most supplements dose at 300mg per capsule — take 1–2 per day. For whole root powder, 1000–1950mg is typical since the extract is less concentrated. Always follow the label on your specific product.
When should I take ashwagandha?
For sleep and stress: take before bed. For testosterone and athletic performance: split the dose — once in the morning, once at night. Consistency matters more than timing — take it the same time every day.
How long before I see results?
Most people notice improved sleep and reduced anxiety within 2–4 weeks of consistent use. Testosterone and athletic performance benefits typically show up after 8–12 weeks. Give it at least a month before judging results.
Is ashwagandha safe? Any side effects?
Ashwagandha is generally well-tolerated at standard doses. Rare side effects include mild GI upset (take with food to avoid this). Not recommended during pregnancy. If you're on thyroid medication or immunosuppressants, check with your doctor first.
