Marketing Claims Vs. Reality
High thymoquinone content.
The Supplement Facts panel declares no thymoquinone amount or percentage. Whatever the oil contains, the label does not commit to it.
Third-party tested, GMP.
Both marks are printed on the panel, which is more than most liquids here manage.
Light taste.
The front panel states it and the oil is noticeably milder than the unrefined competitors; the trade-off is that a lighter taste can indicate a lower thymoquinone fraction.
What Our Test Actually Found
The marketing and the panel disagree
MAJU's listing is built around thymoquinone potency. The label is silent on it. We score the label, and on the label this is an undeclared oil with good manufacturing marks.
You pay a premium for seals, not for strength
GMP and third-party testing are worth having. They are not worth a third more per teaspoon than Amazing Herbs, which declares 48 mg thymoquinone and costs less.

MAJU prints more quality-programme marks on its panel than any other liquid here: GMP, third-party tested, vegan, gluten-free, paleo. What it does not print is the thymoquinone number its marketing leans on. That, plus a price roughly a third higher than Amazing Herbs for the same 5 g teaspoon, keeps it in the lower half of the list despite a genuinely well-made oil.
MAJU markets its black seed oil on thymoquinone strength and a light, drinkable taste. The panel we read supports the second claim and not the first: 5 g of cold-pressed black cumin seed oil per teaspoon, 45 servings per 8 fl oz, with GMP, third-party tested, vegan, gluten-free, paleo and made-in-USA marks, and no thymoquinone amount or percentage anywhere on it. At around $37 it is the most expensive liquid on the list.
Well made, well marked, over-priced for what the label commits to
If the testing marks are what you buy on, MAJU is the liquid with the most of them. If you buy on thymoquinone, as the brand asks you to, the panel gives you nothing to hold it to. Amazing Herbs does, for less.
If This Doesn’t Fit — Try These
01Amazing Herbs Black Seed Oil
Thymoquinone is why black seed oil works, and this is the one liquid that tells you how much you are getting.
02Nature's Way Organic Black Seed Oil
If organic certification is a must, this is the black seed oil to buy: standardised thymoquinone, a fatty-acid breakdown and a USDA seal on one panel.
03Bio Nutrition Softgels
A declared thymoquinone amount, the exact trial dose and no taste, for about thirty-three cents a day.
Quick Answers
Does MAJU black seed oil have more thymoquinone than other brands?
The panel does not say. No amount or percentage is printed, so the potency claim in the listing cannot be checked against the label. Amazing Herbs (48 mg per 5 mL) and Nature's Way (0.6 percent) are the two liquids that declare theirs.
Is MAJU black seed oil organic?
No organic seal is printed. The panel carries GMP, third-party tested, vegan, gluten-free and paleo marks instead.
