Benefits
Caffeine-level cognitive performance — without caffeine
In the pivotal 96-person clinical trial published in Frontiers in Neuroscience, CardaMind (MA2-24) at 250 mg alone showed significant improvements on Shifting Attention Test, Symbol Digit Coding, and Stroop tests — comparable to 200 mg caffeine, though to a lesser extent. Plant-based, caffeine-free cognitive support that matches the cognitive benefits of caffeine — a unique commercial position.
Extends caffeine benefits to 8 hours when combined
When combined with caffeine, CardaMind enhanced and sustained cognitive effects for up to 5 hours (vs 3 hours alone), with reaction time benefits extending to 8 hours. Positions CardaMind as a plant-based nootropic adjunct to enhance and sustain caffeine-mediated cognitive benefits and potentially mitigate post-caffeine performance decline. Useful for products targeting all-day mental performance.
Fast 1-hour onset
Following a single dose, cognitive benefits were observed within 1 hour — including support for focus, accuracy, and reaction time. Fast onset is unusual for botanical cognitive ingredients (most require 4-12 weeks) and competitive with caffeine's onset (15-45 minutes). Supports use in pre-meeting, pre-task, and acute performance contexts vs daily preventive cognitive support.
Sustained executive function and processing speed
CardaMind supported outcomes in Central Nervous System Vital Signs (CNSVS) tasks measuring executive function, processing speed, and selective attention. The Shifting Attention Test assessed cognitive flexibility; the Stroop Test measured mental control by requiring identification of ink colors while ignoring conflicting word meanings. Sustained effects for up to 3 hours after single dose.
BDNF expression and neuroprotection mechanism
Bioactives preserved by the water-based extraction may modulate neurotransmitters and support BDNF (Brain-Derived Neurotrophic Factor) expression alongside neuroprotection. BDNF supports neuroplasticity, learning, and memory — distinguishing CardaMind from pure stimulant cognitive enhancers. Mechanism supports long-term cognitive applications beyond acute effects.
Water-soluble formulation flexibility
CardaMind is water-soluble and mild-tasting — making it suitable for supplements, gummies, and functional beverages. The format flexibility supports modern delivery systems consumers prefer. Distinguishes CardaMind from oil-soluble cognitive ingredients limited to capsule formats. The mild taste also avoids the off-flavor masking challenges of many herbal extracts.
Avoidance of post-caffeine performance decline
Trials documented that CardaMind may mitigate post-caffeine performance decline — the cognitive crash that often follows caffeine effects wearing off. The extension of cognitive benefits to 8 hours (vs 3-5 hours for caffeine alone) supports smoother performance over a workday. Practical advantage over caffeine-only products that produce afternoon crashes.
Mechanism of action
Neurotransmitter modulation
Black cardamom bioactives preserved through water-based extraction may modulate neurotransmitters involved in attention, focus, and cognitive processing. The neurotransmitter mechanism explains the fast 1-hour onset — direct effects on existing neurotransmitter signaling produce rapid effects vs longer-term neuroplastic mechanisms.
BDNF expression support
Brain-Derived Neurotrophic Factor (BDNF) is a key protein supporting neuronal growth, survival, and plasticity. BDNF levels decline with age and chronic stress. CardaMind bioactives may support BDNF expression — the mechanism behind the longer-term cognitive wellness applications beyond acute single-dose effects.
Neuroprotection via antioxidant compounds
Black cardamom contains diverse polyphenolic and terpenoid compounds with antioxidant activity. Brain tissue is particularly vulnerable to oxidative damage due to high metabolic activity. Neuroprotective antioxidant effects support cognitive function preservation across the lifespan — complementing the acute performance effects.
Synergistic enhancement of caffeine pharmacology
Combined CardaMind + caffeine effects exceed either component alone — true synergistic rather than additive interaction. Mechanism may involve different bioactive targets converging on cognitive performance, plus CardaMind potentially slowing caffeine metabolism or extending its functional effects. Mechanism explains the 8-hour reaction time benefit duration.
Water-based extraction preservation
Standard extraction with organic solvents (ethanol, acetone) can lose or degrade heat-sensitive water-soluble bioactives. Akay's water-based process preserves these compounds — explaining the extract's bioactivity at 250 mg vs higher doses needed for alternatively-extracted cardamom. The extraction technology is patent-protected (MA2-24).
Clinical trials
Randomized, double-blinded, placebo- and active-controlled, comparative study evaluating CardaMind (MA2-24) cognitive effects alone and in combination with caffeine. Single-dose pharmacodynamic design with CNS Vital Signs assessments at baseline and 1-, 3-, 5-, and 8-hour post-dose. Published in Frontiers in Neuroscience 2026 (doi:10.3389/fnins.2026.1786880).
96 healthy working-class adults aged 35-65, randomized 24/group to placebo, MA2-24 (250 mg), caffeine (200 mg), or combination.
MA2-24 (250 mg) alone showed significant improvements on Shifting Attention Test, Symbol Digit Coding, and Stroop tests — comparable to 200 mg caffeine, though to lesser extent. Single-dose effects within 1 hour, sustained for 3 hours alone. When combined with caffeine, effects enhanced and sustained for 5 hours, with reaction time benefits extending to 8 hours. Established CardaMind as plant-based nootropic adjunct that may mitigate post-caffeine performance decline.

Not applicable — in vitro and preclinical mechanism characterization.
Black cardamom bioactives preserved by water-based extraction may modulate neurotransmitters, support BDNF expression, and enhance neuroprotection. The mechanism foundation supported the human trial findings of fast 1-hour onset (neurotransmitter mechanism) combined with sustained effects (BDNF/neuroprotection mechanisms). Multi-mechanism approach distinguishes from single-target cognitive ingredients.
