SUPPLI-X KSM-66 Ashwagandha – Premium Adaptogen for Cortisol Control, Stress Relief & Deep Sleep

Chronic stress is silently sabotaging your gains, sleep, and focus. Elevated cortisol from endless deadlines, brutal workouts, or daily grind tears down muscle, spikes anxiety, and wrecks recovery. SUPPLI-X KSM-66 Ashwagandha Premium with Black Pepper delivers clinically backed relief — targeting cortisol at the source for peak performance and calm under pressure.

The Science Behind KSM-66

KSM-66 is the gold standard in ashwagandha: a patented, full-spectrum root extract standardized to 5% withanolides, extracted without leaves or stems for maximum potency and purity. Unlike generic ashwagandha powders, this is the exact form used in rigorous human clinical trials.

Studies show significant cortisol reduction at 600mg per day (PMC6979308). Neuroscientist Andrew Huberman highlights "enormous changes in serum cortisol" with 300mg twice daily — making KSM-66 a staple for biohackers optimizing hormone balance and stress resilience.

Sleep quality improves too — a clinical trial found KSM-66 improved Pittsburgh Sleep Quality Index scores by 40.15% (vitafoodsinsights). We've enhanced this formula with black pepper extract (BioPerine/piperine) to maximize bioavailability, ensuring more active withanolides reach your system.

GMP-certified. Made in the USA. Third-party tested. Free of artificial additives. Engineered for results, not hype.

Biohackers stacking for hormone optimization. Gym warriors fighting cortisol-induced muscle breakdown post-workout. Stressed professionals juggling 60-hour weeks who need an edge to stay sharp and recover fast. Anyone who is pushing limits but feeling the burnout — this is your adaptogen upgrade.

Pairs Well With

Stack for synergy: Combine with SUPPLI-X Magnesium Glycinate to amplify sleep quality and muscle recovery — magnesium calms the nervous system while KSM-66 handles the cortisol load. For evenings, add SUPPLI-X Reishi Relax Gummies to deepen relaxation without grogginess — the ultimate wind-down stack for high-performers.

How to Use

Take 2 capsules daily: 1 in the morning and 1 in the evening, 20–30 minutes before meals. This matches the 300mg twice-daily protocol totaling 600mg — the dose studied for stress, anxiety, and sleep benefits. Use consistently for at least 8 weeks. Store in a cool, dry place.

Frequently Asked Questions

How long until I notice effects?
Most users report subtle calm within 1–2 weeks, with peak cortisol and sleep benefits emerging at 4–8 weeks. Consistency matters — this is not a one-dose fix.

Will it make me drowsy or crash my energy?
No. KSM-66 is an adaptogen, not a sedative. It regulates cortisol without CNS depression. Most users feel calmer and more focused, not tired.

Is it safe to stack with creatine or pre-workout?
Yes. KSM-66 pairs cleanly with most performance supplements. No known interactions with creatine, caffeine, or standard pre-workouts at normal doses.

Why KSM-66 and not regular ashwagandha?
KSM-66 is root-only, standardized to 5% withanolides, and backed by 24+ human clinical trials. Generic ashwagandha varies wildly in potency and uses leaf extract, which has a different and far less studied profile.
