Who this is for
Built for people who read the panel first.
If you already track your sleep, you already know why one variable at a time matters. Single-ingredient bottles are the only format that lets you change one thing and know what did it. Three places to start — each one three separate decisions, not a bundle.
The evening three
Taken at night. Change one at a time and you can tell which one did what.
The daily baseline
Three micronutrients, each at a dose printed on the front panel.
The desk three
Daytime compounds. Each is a separate decision you can keep or drop.
Nothing here is a bundle with a discount attached. It is a suggested place to begin, listed so you don’t have to guess — and every bottle in it is sold on its own.
The exclusions
Nothing in it you didn’t ask for.
Five compounds this category is happy to sell that we will not, and the reason for each. A range is defined as much by what it refuses as by what it stocks.
Read the full list- NMN
- Excluded from the dietary-supplement definition by FDA position.
- UROLITHIN A
- Patent-encumbered. One company controls the ingredient.
- NAC
- Drug-exclusion history and an enforcement campaign behind it.
- IRON
- Carries a mandatory pediatric poisoning warning. Avoidable.
- HORMONE PRECURSORS
- Tongkat, high-dose DHEA precursors. Not our category.

One ingredient. Nothing to decode.
