Power Blend — The Research

Cordyceps militaris increases ATP synthesis and oxygen utilization at the cellular level — the same mechanism energy drinks fake with stimulant overload. Rhodiola Rosea reduces perceived fatigue and physical exertion without dependency or crash. Taurine — found in every energy can on the market — is here without the 27g of sugar it's always buried under. CoQ10 supports the mitochondrial electron transport chain, the foundation of all aerobic energy production.

"Rhodiola rosea supplementation reduced perceived effort and improved endurance performance in a double-blind crossover trial." — De Bock et al., Int. Journal of Sport Nutrition, 2004
🌙

Night Ritual — The Research

Sleep is when every performance metric you optimized during the day actually consolidates. Magnesium Glycinate reduces sleep onset time and improves sleep architecture. Ashwagandha Root Extract (standardized to 5% withanolides) lowers cortisol — the primary hormone that keeps high-performers awake when they should be recovering. Tart Cherry provides natural melatonin precursors via the tryptophan pathway, with no synthetic suppression of your body's own production.

"Ashwagandha root extract improves sleep quality and sleep onset latency in subjects with insomnia." — Langade et al., PLOS ONE, 2019

Questions

Common Questions

Most supplement gummies underdose their actives to work around taste limitations. Nurostak formulas are built around clinical dosage targets first — we publish every milligram on the label so you can verify against the research yourself. No proprietary blends, no hidden doses.
From your account dashboard, hit "Manage Stack" at any time. You can pause for 1, 2, or 3 months, skip a shipment, or cancel entirely. We'll text you 3 days before each batch ships so you always have a chance to make changes. No phone calls required — ever.
Your first shipment arrives in sleek branded packaging with a 30-day supply of both Blends. Every month after that ships in compact, letterbox-friendly refill pouches. Simple, zero waste, zero bulk.
Yes. Every formula is dosed to match or approximate the dosages used in peer-reviewed clinical trials — not the token amounts found in most supplement blends. We publish the exact milligrams per serving on the product page so you can cross-reference the research directly.
Because the day/night cycle is the foundation. Energy drinks break it — they spike you up and leave you in recovery debt that poor sleep makes worse. Power Blend and Night Ritual are designed as one closed loop: fuel performance during the day, pay down the recovery debt at night. Get this system working and everything else compounds. More Blends are coming — but we're launching with the ones that matter most first.
We're targeting a launch in Q1 2027. Early access waitlist members get first shipment priority and a 20% discount on their first month. Join the waitlist above to lock in your spot — we'll keep the list honest and won't oversell our initial batch.
