Formula snapshot
Built for better night sleep and recovery
Core components
Five ingredients for the evening close
Regen is built around a clear evening role: downshift, recovery focus, and a calmer close to the day.
Reishi
Magnesium
Glycine
Ashwagandha
L-Theanine
Reishi dual extract
Contributes to the calm evening base of Regen, giving the formula its recovery-focused mushroom identity.
Magnesium bisglycinate
Contributes to the mineral foundation: muscle function, nervous-system balance, and the recovery role of the evening routine.
Glycine
Contributes to the downshift layer of the formula, supporting the feeling of a calmer evening protocol.
Ashwagandha
Contributes to the stress-and-calm layer, so Regen feels built for winding down instead of simply taking a product.
L-Theanine
Contributes to the softer mental close: a quieter headspace in the evening, without caffeine.
How to use
A fixed evening protocol
- Take 3 capsules in the evening with water.
- Use it as a repeatable downshift cue after the day is finished.
- Pair it with a calm routine instead of treating it as an emergency fix.
Regen should make the evening part of the ritual simple: take it, lower the tempo, and close the day with the same structure.
Fit check
Who should choose Regen
- You want the evening part of the Cortex Ritual to feel deliberate and repeatable.

Skip or wait
When Regen may not be the right first choice
- If your main need is training setup, start with Ignite or the Training Stack.
- If you want a morning routine first, start with Cortex Prime.
- If you are pregnant, nursing, medicated, or unsure, read the label and consult a qualified professional before use.
FAQ
Common questions
Is Regen a sleep medicine?
No. It is a food supplement for better night sleep, recovery and evening downshift, not a medicine or treatment product.
How does it fit with Prime and Ignite?
Prime owns the morning, Ignite owns the training window, and Regen owns the evening close. That is the core Cortex Ritual.
