Each formula is built around one well-studied ingredient, at a full dose, taken at the time of day it's meant for. Every ingredient is listed below.
Why lion's mane: A functional mushroom long used to support focus and mental clarity.* Caffeine-free, so it starts the day without the spike.
Why 7am: For the hours you need to focus.*
Why KSM-66: A full-spectrum root extract and one of the most researched forms of ashwagandha, the classic adaptogen that helps the body adapt to everyday stress.* B6 and B12 support normal energy and nervous system function.*
Why 3pm: The afternoon is when stress tends to build.
Why glycinate: Magnesium bound to the amino acid glycine, a gentle, well-absorbed form that supports relaxation and restful sleep.* No melatonin.
Why 9pm: Taken about an hour before bed, as part of winding down.
Every study below is randomized, double-blind and placebo-controlled. Each tested one ingredient on its own, not our formulas, and some used different amounts than ours, so we list both. Read the papers yourself.

These aren't one-night fixes like a sleeping pill or a coffee. They work by being taken every day, and three things decide how long that takes.
Ashwagandha was measured at 60 days and magnesium at 8 weeks of daily use. Nobody tested a single dose, so a week or two tells you little.*
Most of your magnesium is stored in bone and muscle, not your blood. Topping up those stores takes steady daily intake, and stopping lets them drift back down.
That's the average a UCL study found for a new daily behaviour to stick. After it, 7am, 3pm and 9pm happen without thinking.
Lally et al., European Journal of Social Psychology, 2010The reset arrives as one 90-night box: the whole course on your shelf from night one.
KSM-66 ashwagandha, organic lion's mane at 40% polysaccharides, and magnesium in its gentle glycinate form.
From domestic and imported ingredients, in an FDA-registered, cGMP-compliant facility. Certificate of analysis on request.
The hour is on the front of every bottle. 7am, 3pm, 9pm. That's the whole routine.
First light (lion's mane): 2 capsules in the morning, around 7am. Golden hour (ashwagandha): 2 capsules mid-afternoon, around 3pm. Nightfall (magnesium glycinate): 3 capsules about an hour before bed. No need to plan around meals. The hour is printed on the front of every bottle.
The intended course is 90 nights, every day. The studies behind these ingredients measured results after 4 to 8 weeks of daily use, and it takes about 66 days on average for a daily routine to become automatic. 90 nights covers both.*
Yes. First light is caffeine-free, so it sits fine alongside your morning coffee.
No. Nightfall is magnesium glycinate only.
