What Is Ashwagandha?
Ashwagandha (Withania somnifera), also called "Indian ginseng", is an adaptogenic herb used for centuries in Ayurvedic medicine. Adaptogens help the body adapt to stress — both physical and psychological. Modern thinking holds that ashwagandha is one of the most effective natural supplements for stress reduction, testosterone increase and athletic performance improvement.

🧪 What Science Says: Key Studies
💪 Strength and Muscle Mass
8-week study: the KSM-66 group gained 1.5–1.7 times more muscle mass than the placebo group. Bench press strength increased by ~20 kg more.
🧘 Cortisol Reduction
Systematic review of 5 studies: a reduction in cortisol was observed in ashwagandha studies, especially under chronic stress (effect size varies between individual studies).
🏃 VO2 max Improvement
500 mg ashwagandha per day for 8 weeks — VO2 max increased by 13% compared with the placebo group. Significant endurance improvement.
🧠 Cognitive Function
There is evidence of improvements in memory, reaction time and attention — important for athletes who need quick decisions during competition.
📋 How to Take Ashwagandha?
Dosage recommendations:
- For Beginners: 300 mg KSM-66 (or 125 mg Sensoril) once daily for the first week to assess tolerance
- Standard Dose: 600 mg KSM-66 per day (divided into 2 doses: 300 mg in the morning + 300 mg in the evening)
- Sensoril: 250 mg once daily, preferably in the evening before sleep
- Cycling: It is recommended to take breaks: use for 6–8 weeks, then take a 2–4 week break. This prevents the development of tolerance
