Our Story
Arvonis started with a question most supplement brands skip: if the active compound matters, why doesn't the label say how much is in it?
We built Arvonis around one rule — every claim on the bottle has to be something the customer can check. Stated potency, printed on the label. Third-party tested, every lot. Certificate of analysis available on request. That is the baseline, not the selling point.
Since 2018, that standard has earned the trust of over 100,000 customers in 30+ countries — not through advertising promises, but through what is actually inside the bottle and the receipts to prove it.
Two products. One standard.
Every Arvonis product is built the same way: single-purpose formula, stated potency, third-party verification, and a 90-day window to judge the results yourself.
How we earn your trust.
We cannot promise outcomes — nobody honest can. What we can promise is the method behind every bottle, and the documentation to back it up.
- Stated potency, printed on the label. Our Ethiopian Reserve is standardized to its stated thymoquinone level — up to 4.64% — and that number is on the bottle. No estimates from oil weight, no "proprietary blend" math that hides the measurement.
- Third-party tested, every batch. Each production lot is independently tested for potency, heavy metals, and microbial safety before it ships. Ask us for the certificate of analysis (COA) for the lot you received — it is yours to read.
- GMP-certified, FDA-registered US facility. Manufactured in a United States facility registered with the Food and Drug Administration, operated under current Good Manufacturing Practice standards for dietary supplements (21 CFR Part 111). Non-GMO. Gluten-free.
- Ninety days to judge it yourself. A daily reserve works by accumulation, not by dose. If a bottle has not earned its place in your routine within ninety days, one email to care@arvonis.co gets your money back — no return shipment, no form designed to make you give up.
Who stands behind Arvonis.
Arvonis is based in Boulder, Colorado. We source, test, and release every product under the same standard: if we cannot document it, we do not claim it.
Our Ethiopian Reserve black seed oil is sourced from highland farms in Ethiopia at approximately 8,000 feet — where volcanic soil, thin air, and intense sun stress the Nigella sativa plant into concentrating its marker compound, thymoquinone, at levels most commercial supply chains never preserve. Each lot is cold-pressed, standardized, third-party tested, and numbered before release.
Published research on our key botanicals.
Nigella sativa (black seed) and its marker compound thymoquinone are among the most-studied botanicals in modern phytochemistry. These are peer-reviewed studies that informed our formulation — not marketing claims about our product.
