The Science
We don't add anything for marketing purposes. Every compound in a CryøStäk formula is backed by research, dosed for efficacy, and clean enough to stand alone.
Adaptogens
Adaptogens are a class of plants and fungi that help the body adapt to physical, chemical, and biological stress. They don't stimulate or sedate — they normalize. Used in Ayurvedic and traditional Chinese medicine for thousands of years, now validated by modern research.
Nootropics
Nootropics — sometimes called "smart drugs" — are compounds that support brain function, including focus, memory, creativity, and mental clarity. CryøStäk uses only natural, non-prescription nootropics with well-documented safety profiles.
Full Breakdown
Hericium erinaceus
Lion's Mane is a medicinal mushroom long used in East Asian traditional medicine and now studied extensively for its neuroprotective properties. It stimulates the synthesis of Nerve Growth Factor (NGF), a key protein for the maintenance and growth of neurons.
Withania somnifera (KSM-66®)
One of the most well-researched adaptogens in the world. CryøStäk uses KSM-66, the highest-concentration full-spectrum root extract available, standardized for withanolides — the active compounds responsible for its adaptogenic effects.
Rhodiola rosea
A flowering herb native to the cold, high-altitude regions of Europe and Asia. Used by Scandinavian and Russian populations for centuries to increase physical endurance and resist mental fatigue. Particularly effective for combating burnout.
Green tea amino acid
An amino acid found naturally in green and black tea. L-Theanine promotes alpha brain wave activity — the state associated with calm, focused alertness (like meditation or being "in the zone"). When combined with caffeine, it smooths the energy curve completely.
Brahmi herb
A creeping herb used in Ayurvedic medicine as a brain tonic for centuries. Bacopa contains active bacosides that repair damaged neurons and improve signaling in the hippocampus — the brain's memory center. Effects build over time with consistent use.
Camellia sinensis (green tea)
CryøStäk uses caffeine derived from green tea rather than synthetic anhydrous caffeine. At roughly half the dose of a standard energy drink (75mg vs 150mg+), it's enough to activate your focus without triggering the overstimulation cycle that most energy drinks rely on.
Clean Commitment
Just as important as what's inside is what's left out. These are hard no's — not exceptions, not "trace amounts."
