Why It Works
Mechanism, not marketing.
Cognitive performance depends on acetylcholine availability. Think's Alpha GPC and Huperzine A combination targets both sides of the equation — production and preservation.
Mind adds the circulatory component. Ginkgo biloba's mechanism is cerebral vasodilation — more blood to the brain means better delivery of everything else in the stack.
5-HTP addresses the mood floor. Cognitive performance degrades with low serotonin — anxiety, poor sleep, and mental fatigue all trace back to serotonin insufficiency. 5-HTP is the most direct intervention available without a prescription.
01
Acetylcholine Support
Alpha GPC provides the choline substrate. Huperzine A inhibits acetylcholinesterase — slowing breakdown. Net result: more acetylcholine available for cognitive function.
02
Cerebral Blood Flow
Ginkgo biloba's vasodilatory effect increases cerebral circulation — improving delivery of oxygen and nutrients to working neural tissue.
03
Serotonin Precursor
5-HTP converts directly to serotonin. Supports mood stability, reduces anxiety, and improves the sleep quality that cognitive performance depends on.
04
Adaptogenic Baseline
Ginseng and Rhodiola address stress-induced cognitive degradation — preventing the performance drop that occurs under sustained mental load.

Common Questions
FAQ
When do I take each product?
Think: 1 capsule in the morning with food (contains caffeine — don't take after 2pm). Mind: 1 capsule with breakfast. 5-HTP: 1 capsule before bed — it supports serotonin production overnight.
Does Think contain caffeine?
Yes — 75mg, roughly equivalent to a small coffee. If you're sensitive to caffeine, take it earlier in the day and reduce other caffeine sources.
Can I take all three together?
Think and Mind both taken in the morning. 5-HTP taken separately at night — taking it with the others reduces the sleep benefit.
