We Make One Thing, and We Make It Honestly.
No proprietary blends. No mystery doses. No ingredient list padded out to look impressive on a shelf. Just full-strength formulas, built from what the research actually supports — and nothing you'd have to look up to understand.
Why We Started
Arvellum began with a frustrating hour spent reading the back of a sleep supplement bottle. Nine ingredients, one dose, and a single line that mattered most: "proprietary blend, 850mg." No breakdown. No way to know if there was 2mg of melatonin in that jar or 200.
That's not a small thing. It's the whole point of taking a supplement in the first place — knowing what's actually going into your body, and in what amount. So we built the label we wished existed: every ingredient, every milligram, printed in full.
"If a brand won't tell you how much is in the capsule, that's usually because the answer wouldn't convince you to buy it."— Arvellum, founding note
The Three Rules We Don't Break
Full transparency, always
Every ingredient and every milligram is printed on the label. No blends, no umbrella terms, no rounding down.
Doses that match the research
We formulate to the amounts studied in clinical literature — not the smallest amount that still lets us list an ingredient.
As few ingredients as it takes
Every addition has to earn its place. If it doesn't change how the formula works, it doesn't go in the capsule.
How Night Actually Gets Made
-
1
Sourcing
Valerian root, chamomile, lemon balm and passion flower are sourced from suppliers who provide certificates of analysis for every batch — so we know what we're formulating with before it ever reaches a capsule.
-
2
Formulation
Doses are set against published research on each ingredient, then balanced so nothing overpowers or undercuts the others — the goal is a formula that works as a system, not a stack of single ingredients.
-
3
Manufacturing
Every batch is produced in a cGMP-certified, U.S.-based facility, under the same quality controls used across the supplement industry's regulated manufacturers.
-
4
Your nightstand
What ships is exactly what's on the label — nothing substituted, nothing quietly reduced to cut costs.
What We Hold Every Batch To
Manufactured in a U.S.-based facility from sourcing through final packaging.
Produced under current Good Manufacturing Practice standards for dietary supplements.
No genetically modified ingredients in any formula, ever.
If it's in the capsule, it's on the label — with the exact amount next to it.
Ingredients are verified against certificates of analysis before formulation.
Nothing added purely to bulk out a capsule or extend a bottle count.
A Small Note From Us
Arvellum isn't trying to be everything. We started with one formula, for one problem — sleep — because we wanted to get it right before doing anything else. Every product we add from here follows the same three rules: full transparency, real doses, and nothing that doesn't earn its place in the capsule.
If that's the kind of supplement brand you've been looking for, we'd like to earn your trust one honest label at a time.
