PRIME NATURAL
COMPANY INFO
Prime Natural is a trademark of Prime Cosmetics LLC, based in Beaverton, Oregon. The company offers a range of essential and carrier oils. According to their website, Prime Cosmetics sources its oils through partner importers and then processes and bottles them in the USA.
● On March 20, 2025, we reached out via email requesting product details and any available lab analyses related to their black seed oil. The company responded with very limited information. As a result, all other insights included in this review were obtained through independent research using publicly accessible sources.
It's worth noting that only three companies replied to our inquiry: Piping Rock, Bionatal, and Prime Natural.
PACKING AND SAFETY SEAL
The oil is packaged in a standard amber pharmaceutical-style bottle. It includes a plastic cap with a transparent shrink wrap, and a standard plastic liner inside the cap. However, the bottleneck is not foil-sealed.
● The current sealing method is not sufficient to fully prevent leakage, especially during high-temperature transport, when black seed oil can expand by up to 20%.
SEEDS ORIGIN
According to both the product label and the official website, Prime Natural black seed oil is made from Turkish-grown Nigella sativa seeds.
OIL DISCRIPTION
The oil has a light yellow, cloudy appearance, with a pleasant herbal aroma and a light level of bitterness.
In our assessment, this oil is identical in color, flavor, and taste to other well-known Turkish black seed oil brands such as Zhou Nutrition, Piping Rock, Kiva, Sweet Sunnah Premium, Maju, and Amazing Herbs Premium. However, it shows a noticeable difference in bitterness compared to Freshfield, Healths Harmony, Rawya, and Rawya Extra Strong.
All members of our testing team noted that the bitterness is either milder or slower to develop, a sensory pattern also observed in Kiva and Maju oils.
On the website we found a picture of the oil which is by color shares characteristics with Ethiopian oil but the actual color we got in the bottle is totally different and lighter (obsoletely Turkish).
● An interesting observation: Kiva, which shares the same lower-bitter profile, also features the exact same TQ statement — “Over 1.5%” — on its label. Additionally, both Kiva and Prime Natural are USDA Organic certified. This suggests they may be sourcing from the same importer, who has conducted lab testing and obtained USDA certification for the oil.
THYMOQUINONE (TQ)
The label on Prime Natural black seed oil states a TQ level of “Over 1.5%,” which is consistent with the estimated thymoquinone content found in many Turkish black seed oils. While none of the following brands have publicly shared certified lab analyses, their reported TQ levels fall within a similar range:
-
Maju, Rawya, Rawya Extra Strong – Minimum 2%
-
Sweet Sunnah Premium – 1.71%
-
Freshfield – 1.64%
-
Kiva – Over 1.5%
-
Amazing Herbs Premium – Minimum 1.2%
● As confirmed by experienced farmers, TQ levels can vary even among seeds from the same country. In Turkey — a country with significant elevation differences — factors such as altitude and climate play a major role in determining the potency of the seeds. Farms in the northern Black Sea region experience cooler temperatures, while those in the southern Mediterranean region face warmer climates, both of which contribute to variations in thymoquinone concentration.

Industry Clarifications:
(The following industry points are worth noting)
-
"Unrefined" ≠ Non-Filtered: Even unrefined oils are typically filtered and don’t contain seed particles.
-
"Cold Press" misuse on the label: The term is widely used without proof. True cold pressing should be validated by testing for compounds like Benzo(a)pyrene and related PAHs.
-
"Organic" ≠ Pesticide-Free: USDA standards still allow natural pesticides (§§ 205.601 - 205.602). No Nigella sativa seeds are entirely free from them.
-
"Non-GMO" claims are unnecessary: Nigella sativa is not genetically modified, and global demand doesn’t justify GMO cultivation.
FINAL RANKING #5-A
Positions #1 and #2 in our ranking are clearly held by the world’s most powerful black seed oils — both made from Ethiopian Nigella sativa seeds.
Position #3 (sub-positions A through D) is assigned to select Turkish black seed oils that show slightly more bitterness than the rest, setting them marginally above other Turkish-sourced products.
Position #4 (sub-positions A through E) includes Turkish black seed oils that display a standard, medium level of bitterness. Even after in-depth testing, no significant differences were observed among them.
Position #5 is reserved for the remaining Turkish black seed oils that exhibit only mild bitterness, with no noticeable distinctions even after deeper analysis.
Within this group of lighter oils, there was no standout performer in terms of quality or potency. However, we awarded sub-position “A” to Prime Natural, as it was the only company in this category that responded to our request for product information — demonstrating a basic level of customer engagement.
