"I wanted something simple I could take every day to support my gut without adding another complicated cleanse or supplement stack. Arvonis fit that perfectly. Two softgels with food, one ingredient, and something I can actually stay consistent with."
"I've tried probiotics, powders and routines that became too complicated to keep up with. What I liked about Arvonis was how straightforward it was — black seed oil, a stated thymoquinone level, and two softgels a day. It has become an easy part of my gut routine."
"I had used black seed oil before, but I never really knew what I was getting. Arvonis was the first one I bought where the thymoquinone level was actually stated and the batch was tested. That made much more sense to me than just trusting the words 'black seed oil' on a bottle."
"I wasn't looking for a harsh cleanse or something that would turn my routine upside down. I wanted consistent support for my gut from something clean and concentrated. Arvonis checked the boxes for me — simple formula, clear potency and easy to take every day."
Four Ways It Supports Your Gut Environment.
Your gut is an environment. What lives there, how well it stays balanced, and how consistently you support it all matter. Arvonis gives that environment one concentrated, standardized botanical input every day.
Supports a gut environment that is less welcoming to parasites and unwanted organisms — without turning your routine into a harsh cleanse or complicated protocol.
Supports the body's normal cleansing processes with steady daily use rather than a one-time purge designed to make something dramatic happen overnight.
Supports healthy digestive function and the balanced internal environment your gut depends on every day.
Every serving delivers the same standardized Ethiopian black seed oil with a stated thymoquinone potency — so the input you take today matches the one you take weeks from now.
WHY POTENCY MATTERS
One seed, one oil, one number. The thymoquinone in cold-pressed Nigella sativa is what black seed oil is measured by, and every Arvonis release is standardized to a stated level of it.
No blend to hide behind. The number is on the label, and the batch is tested before it ships.
Thymoquinone is the compound black seed oil is measured by
It supports antioxidant defenses and healthy inflammatory balance
Cold-pressing protects it — heat and solvents do not
Every batch is standardized, then third-party verified
Highland-grown Nigella sativa, selected for the strength of its marker — never anonymous commodity supply.
The oil is pressed without heat or solvents, so what the seed made is what the softgel carries.
Each batch is standardized to its stated thymoquinone level, then verified by an independent third-party lab before it ships.
Only then does the batch earn its number — sold while it lasts, covered by the 90-day standard.
HOW TO TAKE
Two softgels, once a day, with food
Take both softgels together with food. That is one full serving — 800 mg at the batch's verified potency.
Pick the meal you never skip and stay with it. Sixty softgels is a thirty-day run, so one bottle is one month.
Timeline
Two softgels a day is 37 mg of thymoquinone. The only variable that matters is how many days you keep going — here is exactly what that adds up to.
Two softgels, 37 mg of thymoquinone. Nothing dramatic happens on day one, and anything promising otherwise is selling you the wrong thing.
518 mg taken, unbroken. This is the stretch where a routine either sticks or quietly stops. Same time each day is the whole trick.
1,554 mg in. This is where daily use stops being an experiment and starts being a habit you no longer think about.
2,590 mg and counting. One bottle is thirty days, so week ten is your third. From here it is upkeep: same two softgels, same time.
Ethiopian highland farms near 8,000 feet — thin air, volcanic soil, hard sun. The conditions that stress the plant are the same conditions that concentrate what matters in it.
Every figure here is printed on the bottle or on the certificate of analysis for this lot. Nothing on this card comes from a survey.

90-day money-back
A full ninety days to judge it. One email gets your money back — no return shipment, no form to fill.
FAQ
Most bottles tell you how much oil is inside. Arvonis tells you what the oil delivers: a stated thymoquinone potency (up to 4.64%), one named Ethiopian origin, cold-pressed with no solvents, and an independent lab test on every batch — all printed on the label. One ingredient, no fillers, no carrier oil, and ninety days to judge it.
One ingredient: 100% pure Ethiopian black seed oil (Nigella sativa), 800 mg per 2-softgel serving. No fillers, no blends, nothing added.
Thymoquinone is the marker compound black seed oil is measured by, and every release is standardized to a stated level of it, printed on the label.
It supports the internal systems everyday life draws on — antioxidant defenses, inflammatory balance, digestive function — as a daily reserve, not a quick fix.

Black seed oil is an oil, so take the two softgels with food. Inside a sealed softgel there is nothing to taste and, for most people, nothing to notice. If you have a sensitive stomach, start with your largest meal of the day.
No. The softgel stays sealed until it is well past your tongue, so there is nothing to taste going down and no aftertaste after.
