Below is a very brief summary of some of the research on these compounds. For detailed information about clinical trials on these compounds, click here.
Theacrine - Shown in a 2016 randomized, double-blind, placebo-controlled study to improve energy and concentration while decreasing levels of fatigue, anxiety, and irritability. Theacrine also increases ratings of alertness, attention, and motivation. Unlike caffeine and other stimulants, recent evidence has shown that people who take theacrine do not report a tolerance buildup to its effects.
α-GPC - A natural compound of choline that is present within the brain. It is a potent precursor to the neurotransmitter acetylcholine, which is associated with memory and learning.
Rhodiola Rosea - Shown in several studies to reduce ratings of fatigue, anxiety, and stress. This ancient adaptogen has long been used for its reported effects on mood and endurance.
Anthocyanin - 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.
Huperzine A - In a double-blind, placebo-controlled trial students were given either huperzine A or a placebo for 4 weeks. Students using Huperzine A scored higher on memory tests than those who took the placebo. Huperzine A is a reversible acetylcholinesterase (AChE) inhibitor, which means it prevents the breakdown of acetylcholine, boosts memory, and supports long-term brain health.

How do I get the best results/when should I take Halcyon?
Halcyon is designed to be taken daily to support energy, memory, focus, and mood as well as long-term brain health.
We recommend taking 2-3 Halcyon capsules with your morning coffee or tea. Feel free to take a second serving mid-afternoon for those extra long days - just avoid taking it within four hours of bedtime.
Halcyon is optimized to be taken daily to maximize long-term benefits - Halcyon's formula is designed to be adaptogenic, which means it uses compounds that have been shown in clinical studies not to build a tolerance. Additionally, ingredients such as Huperzine A, and Anthocyanin have been shown in clinical studies to work best when taken 12 weeks or longer.
Halcyon was formulated to deliver immediate effects on focus, mood, and energy, and to support memory, neuroplasticity, and cognition with long term use.
How many capsules should I take?
The recommended dosage is two to three capsules with a full glass of water or coffee. If you react strongly to coffee or tea, we recommend starting with two capsules for the first dose. Alternatively, if two capsules is not providing you the desired effect within 90 minutes of ingestion, you can try taking three to four capsules. Remember, Halcyon is specifically formulated to support cognitive health and performance - for best results take Halcyon daily, once in the morning, and once in the afternoon.
What will I experience?
Your experience will vary based on a number of genetic and lifestyle factors such as sleep, diet, and coffee intake. For more information about lifestyle optimizations to get the most from your Halcyon experience, check out our free online masterclass.
Typically people report feeling increased energy, focus, elevated mood, and more motivation within 90 minutes of the first dose. The effect lasts 4-6 hours and customers report greater focus accompanied by boost in mental energy and motivation. Thoughts become clearer, brain fog lifts, and words come to mind more easily.
Designed for daily use, Halcyon's Dopa-XR™ is a patent-pending cognitive enhancement technology based on a microencapsulation 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 body and the brain.
Dopa-XR™ takes an already powerful nootropic ingredient, Theacrine, and extends its release to support wakefulness and various dimensions of cognition for 4-6 hours.
The result is lasting focus, drive, and mental acuity.
Dopa-XR™ activates similar signaling pathways to caffeine but lasts longer and has a more gradual onset.
Research shows our microencapsulated ingredient (Theacrine), is non-habituating, suggesting users do not develop a tolerance to its effects.
Effects that are extended through our XR release technology include improved focus, memory, and motivation.
Avoid taking within four hours of bedtime. Reminder, do not exceed recommended dose (4-6 capsules per day). Pregnant and nursing mothers, children under the age of 18, and individuals with a known medical condition or who are taking prescription medication should consult a physician before taking this or any dietary supplement.
How long will it take for me to tell if it’s working?
The amount of time before you begin to notice Halcyon’s effects can vary, some report a noticeable increase in focus and motivation within as little as 60 minutes, with a peak around two hours.
The short-term effects will last between a few hours and a few days depending on how much you take and your specific metabolism. According to clinical research, long-term effects including better blood flow to the brain, and increased neuroplasticity take about 12 weeks to show, and provide lasting cognitive benefits, particularly if combined with a brain-healthy lifestyle regimen including sleep, diet, and exercise.

Halcyon was designed to create a neurological environment conducive to brain health and cognitive performance. So while some of the ingredients give you immediate benefits or benefits within a few days, other ingredients are targeted toward enhancing neuroplasticity or the creation of new neurons and dendrites. The result is that if you use Halcyon for months, you are likely to feel the benefits for much longer due to the improved neurological environment.
Can I take Halcyon in addition to other supplements or alongside medication?
If you are concerned about interactions with other supplements or medications, please contact your physician before taking Halcyon.
How do I get the best results?
Cycling on and off
There is no need to cycle (wherein a user takes periodic breaks to regain sensitivity and efficacy) - take Halcyon daily for optimal long-term benefits. It’s designed to be taken daily without a tolerance buildup and is specifically formulated to support cognitive health and performance over the long term. This differs from other nootropics on the market which need to be cycled to give your brain a ‘break.’ Halcyon does not require these breaks, because it is not working against your neurochemistry, but rather is working alongside it, augmenting and optimizing natural processes with nutrients that support brain health.
Halcyon is designed to support cognitive function and productive mental states, supporting you in the moments that count. As part of a brain-healthy lifestyle, Halcyon promotes proper nutrition, exercise, sleep, mental challenge, stress management, and an empowered psychological outlook. Research is clear that these are all essential for a healthy body and brain. We have compiled a rich series of content around ways to apply the latest research on health and lifestyle. You can find out more about this in Halcyon's Neuromethod360 course.
Halcyon is most effective when you are well rested. It is not intended to be a replacement for a healthy sleep schedule. It can, however, provide extra stamina when opportunities to sleep are limited. Optimal sleep is critical for optimal brain function. When performing cognitively-loaded work, sleep becomes even more important, as it is needed to consolidate learning and replenish depleted neurotransmitters. If you have issues with achieving restful sleep or experience minor insomnia, we suggest you try taking Halcyon earlier in the day or lowering the dosage, before ceasing use.
For best results please adhere to the instructions below.
To support optimal brain health and performance, take Halcyon daily. Halcyon pairs well with coffee or tea, and may counteract the negative effects of caffeine such as jitters or anxiety.
Avoid taking Halcyon within 4 hours of bedtime as it has a wakefulness component.
Make sure to drink enough water. Your brain is about 73% water. It takes only 2% dehydration to affect attention, memory and other cognitive skills.
Cannabis or alcohol use may alter the effects of Halcyon. Ask your physician before taking any supplement, and thoroughly disclose lifestyle factors such as cannabis and alcohol use when discussing with your doctor.
I only take Halcyon on extra long work days - do you have a monthly subscription with a lower quantity of capsules?
Halcyon is designed to be taken daily - although you may not feel you need it on “off” days, it’s specifically formulated for daily use leading to optimal cognitive benefits over the long term through better neuroplasticity and blood flow to key areas of the brain. If you need a lower quantity per month, contact email@example.com. We can adjust your subscription to occur every 1.5 months, or every other month, whichever best fits your lifestyle.
