The single-ingredient standard
A blend is a place to hide. One ingredient isn’t.
A proprietary blend is a list of ingredients without doses — legal to print, impossible to check. We don’t sell one. Every bottle holds one compound at one declared dose, so the label reads like a spec sheet, not a pitch.
- One compound per bottle — never a blend
- The dose printed on the front panel
- You control what you combine, and when
The arithmetic
What you actually pay for the thing you came for.
Every figure below is the shelf price divided by the milligrams of compound in the bottle. Use it to compare one brand’s magnesium against another brand’s magnesium — not magnesium against zinc, which are dosed on different scales and tell you nothing side by side.
| Compound | Declared dose | Count | Price | Per 100 mg |
|---|---|---|---|---|
| CG-01 Alpha-GPC | 300 mg | 60 | $46.00 | $0.256 |
| FD-02 Magnesium Glycinate | 120 mg | 90 | $42.00 | $0.389 |
| FD-04 Zinc Bisglycinate | 15 mg | 90 | $28.00 | $2.074 |
| LV-01 CoQ10 Ubiquinol | 100 mg | 60 | $56.00 | $0.933 |
| MB-03 Berberine | 500 mg | 60 | $48.00 | $0.160 |
| RC-03 L-Theanine | 200 mg | 90 | $32.00 | $0.178 |
| Any proprietary blend | undisclosed | — | — | not computable |
“Not computable” is not a dig. A blend prints one total weight for several
ingredients, so there is no denominator to divide by — the number cannot be worked out
by us or by you.
2 products in the range are missing here for the same reason: a standardised extract or a dual-unit vitamin has no single mass figure, and we would rather leave those rows out than invent them.
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.
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.

Ten labels in this aisle. Count how many print the dose on the front. Ours prints one compound, at one dose, on the panel you can read before you buy.
What we don’t have yet
We haven’t tested anything, because nothing has been made.
Most brands in this aisle say “third-party tested” from the first day the site is up. We won’t, because it isn’t true yet — no lot exists to test. Here is exactly what we will publish, and when.
- AT LOT 001
- A certificate of analysis for the lot, linked from the product page.
- ON EVERY LABEL
- The lot code, so you can find the certificate for the bottle you are holding.
- ALWAYS
- The assay value as measured — including when it is not the number we hoped for.
Until then, everything on this site is something you can check by reading the panel.
FAQ
Questions, answered.
The essentials people ask before their first order.
What does single-ingredient actually mean?
One active compound per bottle, at one dose, printed on the front panel. No proprietary blends, no undisclosed filler amounts, no second active hiding behind a trademarked name.
Do you publish test results?
Not yet. No lot has been produced, so there is nothing to test. Independent testing begins with Lot 001, and each lot's certificate will be linked from its product page and findable by the lot code printed on the bottle. Until then, everything we claim is printed on the front panel and can be checked by reading it.
Why is the dose on the front of the label?
Because it is the number that decides whether a product does anything. Putting it on the front removes the choice to bury it.
When can I actually order?
Not yet. Lot 001 has not been produced, so nothing can ship and we are not taking card payments — that is why the buy button is a notify form. Leave an email and you will hear from us the day stock lands, with the shipping timetable at that point.
