The 30-second answer
The Activated Black Seed capsule has 1000 mg of black seed oil, and the serving on the pack is one capsule a day. Beseha’s product information says one or two capsules after meals, and not more than two without a doctor or pharmacist. Studies used 200 to 4,600 mg a day for 1 to 48 weeks, and effects on sugar and blood pressure were mostly measured after 8 weeks or more.
From heritage: a rule of use
In the report of Ibn Abi Atiq in al-Bukhari (5687), a sick man was told to crush five or seven seeds and put drops in the nose with oil. An Islamweb fatwa says no authentic prophetic report sets the number of times or the amount, that this is left to experienced doctors, and that black seed is a remedy, not an act of worship. So the dose is a medical question, not a text, which is why we look at what studies used.

What doses did studies use?
| Study | Dose | Duration | What it found |
|---|---|---|---|
| Asthma (Koshak 2017, 80 people) | 500 mg twice a day | 4 weeks | Better asthma control and fewer eosinophils; lung function not significant |
| Allergic rhinitis (Majeed 2024, 65 people) | 250 mg with piperine twice a day | 15 days | Better nose and eye symptoms; a different product from the study authors’ company |
| Rheumatoid arthritis (Kheirouri 2016, 43 women) | 1 g oil a day in two doses | 2 months | Lower inflammation marker and disease activity vs placebo |
| PCOS in teenagers (Mahmoudian 2025) | 1000 mg extract a day | 16 weeks | Lower fasting sugar, but compared with a drug, not placebo |
| Fatty liver (Khonche 2019, 120 people) | 2.5 mL oil every 12 hours | 3 months | Better liver fat and enzymes; the dose is in mL, not capsules |
| Knee osteoarthritis (Huseini 2022, 116 people) | 2.5 mL oil every 8 hours | 1 month | Less pain; the dose is far more than a capsule |
The full picture: the 2025 Jafari review of 82 studies (Black seed: what 82 clinical studies show) found improvements at doses from 200 to 4,600 mg a day. The 2025 Karimi review in diabetes found fasting sugar fell more after more than 8 weeks, and HbA1c and LDL were better at doses above 1 g a day and with the oil form.
How long should you take it?
- No official duration: studies ran from 1 to 48 weeks, and the big review has no longer data.
- Give it two months: fasting sugar fell more after more than 8 weeks in people with diabetes, per the 2025 review.
- Test your numbers: before you start and after two or three months, and compare with your doctor.
- We do not say “for life”: there is no evidence of safety over years.
Oil or seeds?
The 2016 Sahebkar review on blood pressure (11 trials) found seed powder lowered blood pressure more than the oil. So oil capsules are not the only form studied, and not always the strongest.
Who should ask a doctor first?
- People on blood thinners such as warfarin: a lab study predicted an interaction above 1 g of black seed oil a day, so two capsules would pass that limit.
- People on diabetes or blood pressure medicines: black seed may lower them further, so keep checking your readings before raising the dose.
- People with kidney or liver disease: rare cases of kidney and liver problems have been reported after black seed oil.
- Pregnancy, breastfeeding and children: there is not enough safety data, and LactMed says there is no proof it increases milk.
- Before any surgery, and for anyone allergic to black seed or gelatin.

FAQ
How many black seed capsules should I take a day?
The pack serving is one 1000 mg capsule a day, and Beseha’s information says one or two after meals, not more than two without a doctor or pharmacist.
Should I take black seed before or after a meal?
Beseha’s product information says after a meal with water; none of our sources compares timing.
How long should I take black seed?
Studies ran from 1 to 48 weeks, and the effect on sugar was clearer after more than 8 weeks, so repeat your tests after two or three months.
Does a higher dose work better?
In the diabetes review, doses above 1 g a day were better for some markers, but we do not advise raising the dose without a doctor because of possible interactions and rare kidney and liver cases.
Can I take black seed with warfarin?
Not without asking your doctor; a lab study predicted an interaction at doses above 1 g a day.
Is black seed oil better than the seeds?
A blood pressure review found seed powder lowered pressure more than the oil, so the oil is not necessarily the strongest form.

The bottom line
The capsule has 1000 mg and the serving is one a day after a meal, with Beseha saying two at most without a doctor. Give it two or three months and test your numbers, and do not raise the dose if you take blood thinners or diabetes or blood pressure medicines.
