Each capsule delivers 1,000 mg of genuine KSM-66 Ashwagandha root, standardized to 5% Withanolides. KSM-66® Ashwagandha is the world’s most researched Ashwagandha. The same extract was studied for cortisol regulation, sleep quality, endurance, muscle recovery, and cognitive function. No fillers. No blends. and 50+ clinical studies. One ingredient. One dose. No compromise.

  • Regulates cortisol via the HPA axis
  • Supports deeper, more restful sleep
  • Helps maintain healthy hormonal balance
  • Improves endurance and stamina
  • Supports memory, focus, and mental clarity
  • 1000 mg of clinically studied KSM-66®
  • Root-only extract standardized to 5% withanolides

Ashwagandha works through the HPA axis, the system that regulates how your body releases cortisol, its primary stress hormone. While cortisol is useful in short bursts, chronically elevated levels from stress, poor sleep, or overtraining can disrupt recovery, sleep quality, and mental clarity.

Withanolides, the active compounds in KSM-66®, interact with cortisol pathways to help regulate this response at its source. This same mechanism influences sleep, endurance, cognitive performance, and overall recovery. Each capsule delivers 1000 mg of root-only extract standardized to 5% withanolides, ensuring consistent potency.

These effects build gradually, with noticeable improvements in sleep and recovery typically appearing around Week 4.

Good Fit For

  • Those who wake up tired even after 7–8 hours of sleep 
  • Those who are constantly tired and under stress 
  • Those who have tried ashwagandha before and felt nothing 

Probably Not the Right Fit If…

  • You are pregnant, breastfeeding, or on thyroid medication
  • You want a stimulant or an immediate energy kick 
  • You are not willing to use it consistently for 4 weeks

Take 1 capsule after a meal, once daily. 

  1. Use it every day, at the same time. Consistency is key. 
  2. Give it 4 full weeks. This is not a fast-acting stimulant. 
  3. If you feel mild drowsiness in the first week, take it at night.

Pro-Tip: Ashwagandha works by gradually lowering the baseline cortisol level, not by creating an immediate 'feel.' The change you will notice first is better sleep and less mental noise Week 4.  

DOUBLE THE DOSE. DOUBLE THE DIFFERENCE.

  1000 mg KSM-66 ASHWAGANDHA.

I am a basketball player and train regularly at the gym, where recovery and performance are crucial. Klr.Fit supplements, particularly Alpha Blend Strength and All Day Armour, have provided excellent digestion, effective recovery, and consistent energy support. The products are high quality, deliver exactly what is stated, and integrate seamlessly into a disciplined athletic training routine. Highly Recommended.

I’ve used Klr.Fit’s Ashwagandha and Neuro.Fit, and overall my experience has been really good. Ashwagandha helped improve my strength and reduced the constant fatigue I used to feel from sitting all day. After regular use, I felt more active and balanced. Neuro.Fit is an excellent product for focus. If you struggle with concentration, this is definitely worth trying.

I’ve been using this whey protein regularly after workouts, and it’s been great for recovery. It’s easy to digest, tastes good even with just water, and doesn’t cause bloating. I’ve noticed less muscle soreness and better overall strength with consistent use. I use this BCAA during workouts, and it really helps reduce fatigue. It’s light, refreshing, and keeps me going through intense sessions. Recovery feels faster, especially when training on consecutive days.
