Better Science. Better Nootropics.

Research suggests that the ingredients in Halcyon work the first time you take them, and unlike caffeine, you do not build a tolerance. This means that the feeling you get on day one will be the same a thousand days later.

What could you accomplish with 1000 days of flow state?

I think within the next 5 years most people will be taking some form of brain support to keep their neurotransmitters replenished and their brain running strong.

Its all about being able to access that highly-focused, motivated flow state where we are more creative, sharper, and able to tackle our most important goals. Halcyon was created so you can make the most of every day. No stimulants, no chemicals - just specific, targeted nutrients for brain health and performance.

I take Halcyon to feel more articulate when it counts. I especially like DOPA-XR because it’s longer lasting than coffee and it doesn’t build a tolerance, so I can always count on it to get me in the zone. Give it a try and if you don’t love it, it’s on us.

Activate your flow state

There have been times in your life where you have felt “switched on,” or in-the-zone. This mental state is often referred to as flow.

Take Halcyon first thing in the morning and activate your flow state.

Theacrine, a key ingredient in Halcyon synergizes with your early morning coffee.

Ingredients

Found in Nature. Clinically Studied.

Rhodiola Rosea

Rhodiola rosea has long been used to improve mood and endurance and has been shown to protect against the negative effects of stress on cognitive function.

Rhodiola is a plant, native to various arctic regions. It has a long history of medicinal use in Iceland, Sweden, and others.

Studies have shown Rhodiola Rosea to reduce fatigue, anxiety, and stress response.

It is also used as an "adaptogen" to help the body adapt to and resist physical, chemical, and environmental stress.

Alpha-GPC

Alpha-GPC has been shown to promote long term brain health as well as attention and memory.

Alpha-GPC is present in the brain already, and soy, for example, contains a fatty acid which, when broken down, releases Alpha-GPC.

It rapidly delivers choline across the blood-brain barrier and is a precursor of the neurotransmitter acetylcholine, which is associated with memory and learning. In the frontal cortex and cerebellum, it is able to increase both dopamine and serotonin concentrations.

Theacrine

Theacrine supports memory, attention, and motivation. It activates similar signaling pathways to caffeine, without building a tolerance.

Found in the Herrania and Theocrama plant species, as well as the tea plant Camellia Kucha, theacrine is structurally similar to caffeine.

Shown in a 2016 randomized, double blind, placebo controlled study to improve energy and concentration while decreasing levels of fatigue, anxiety, and irritability.

Unlike caffeine, recent evidence shows that people who take theacrine do not develop a tolerance to its effects, which makes it ideal as a daily nootropic.

Bilberry Extract

Anthocyanin is a potent antioxidant that improves cognitive function, blood flow to and activation of the brain while carrying out cognitive tests.

The fruit and leaves of this plant are one of the best sources of anthocyanins - providing 15 anthocyanin analogues.

In a 2017 study, healthy people who consumed Anthocyanin every day for 12 weeks showed improvements in cognitive function, blood flow to the brain, and activation of the brain while carrying out cognitive tests.

Anthocyanin is cited as enhancing neuron growth by increasing blood flow to the brain and is a potent antioxidant that has been shown to have particularly positive effects on brain health.

Dopa-XR™

Our patent-pending compound, Dopa-XR, extends the release of theacrine, providing a longer lasting boost of energy and focus.

Designed for daily use, Halcyon's Dopa-XR™ is a patent-pending cognitive enhancement technology based on a micro-encapsulation system designed to time the release points in the GI tract to maximize performance. This improves the release profile delivering more sustained effects as these compounds are metabolized in the brain.

Dopa-XR™ takes an already powerful nootropic ingredient, Theacrine, and extends its release to support wakefulness and various dimensions of cognition for several hours. The result is lasting focus, drive and mental acuity. Dopa-XR™ activates similar signaling pathways to caffeine, but lasts longer.

Research shows our micro-encapsulated ingredient (Theacrine), is non-habituating, suggesting users do not develop a tolerance to its effects. strong effects that are extended through our XR release technology include improved memory, attention, and motivation.

Huperzine A

Huperzine A has been shown to enhance memory and learning, memory, neuroplasticity, as well as executive function.

Found in the plant commonly known as northern firmoss (Huperzia serrata).

Huperzine A is a naturally derived acetylcholinesterase inhibitor. Acetylcholinesterase (AchE) is responsible for the breakdown of Acetylcholine, and so by inhibiting AchE, more acetylcholine is made available to the brain.

Several studies indicate its ability to support learning, memory, neuroplasticity, and executive function.

Within days I felt sharper, more focused and alert. I don’t leave the house without taking my Halcyon pills. When I am memorizing a 50 digit number for an audience I want my brain the sharpest it can be but also as someone who likes to learn new topics and meet new people

Halcyon is an irreplaceable tool I have in my mental toolbox to give me that extra edge.

The effects have been great - the focus has helped my efficiency with studying immensely. Oddly enough I’ve also managed to retain most of the important information I needed to finish the architecture of this new RFID product I’m working on.

It’s been over 2 weeks since reading that material as of the writing of this review. This is a great product and I’m looking forward to using this more in the future.
