    The first thing that made sense

    Three years. Two REs. Letrozole, timed intercourse, one failed IUI. Nobody once mentioned inflammation. The environment framing was the first explanation that connected everything instead of just handing me another protocol.

    My RE noticed

    Added this alongside my letrozole cycle. At my next monitoring appointment my RE said my lining looked better than it had in months. She asked what changed. I told her and she said keep going.

    Two years of blank OPKs

    Peed on ovulation strips every single morning for two years and never once got a real surge. Month three on this I got my first unmistakable peak. I cried in my bathroom. I don't care if that's dramatic.

    It's not a magic pill

    Month one I felt nothing and almost returned it. By week 6 my sleep was different and the bloating I'd had for years was gone. Month three my cycle came back to 32 days after running 45–60 for as long as I can remember. It's not instant but something is shifting.

    Wish I found this sooner

    I spent $4,000 on supplements that did nothing. Inositol, NAC, CoQ10, vitex, vitamin D, the entire TTC stack. This is one ingredient and it's done more for my cycle in 10 weeks than two years of stacking ever did.

Why Nothing Has Worked Yet

Letrozole forces ovulation. Clomid forces ovulation. IUI times it perfectly. But none of them change the environment inside the follicle where egg quality actually develops.

Published research points to a hidden inflammatory cascade — driven by a pathway called NF-κB — as a major upstream disruptor of that follicular environment. Most fertility protocols never touch it. High-TQ black seed oil is studied for its effect on that exact pathway.

How It Works

Black seed oil contains a compound called thymoquinone (TQ). A 2024 study in the Journal of Ovarian Research examined TQ's role in the inflammatory environment surrounding ovarian follicles — specifically its studied effect on the NF-κB pathway that disrupts follicular signaling upstream of hormones.

Our oil is cold-pressed to preserve TQ at its full potency. Most women notice energy and sleep shifts within the first few weeks, with cycle-related changes building over the following months.

How Long Will It Take To See Results?

The first things most women notice are better sleep and more stable energy — usually within weeks 1–3. Skin improvements and reduced bloating often follow around weeks 3–5.

Cycle-related changes — regularity, flow, PMS intensity — typically show up around weeks 6–8. For the fullest picture of what it can do, give it a full 90 days. That's why every order comes with a 90-day money-back guarantee.

Can I Take It With My Fertility Medications?

Yes. Loomi is designed to work alongside your existing fertility protocol — not replace any part of it. Women take it with letrozole, Clomid, metformin, inositol, CoQ10, prenatals, and during IUI and IVF prep cycles.

One ingredient. No hormonal interference. As always, check with your doctor before adding anything new to your protocol.

Is All Black Seed Oil The Same?

No. Most black seed oil on the market is extracted using high heat or chemical solvents, which degrades the TQ — the compound that actually matters. Ours is cold-pressed and standardized to a guaranteed 2% thymoquinone concentration. That's the difference between a label claim and a real active dose.

Ingredients

One ingredient. Nothing to hide behind.

Thymoquinone and fertility — how it targets the inflammatory environment inside the follicle
How Does It Work for Fertility?

Most fertility protocols focus on forcing ovulation — the event. But if the inflammatory environment inside the follicle is disrupted, ovulation alone doesn't solve the problem.

Thymoquinone, the active compound in black seed oil, has been studied for its effect on NF-κB — the inflammatory pathway that disrupts that follicular environment upstream of your hormones.

Common Questions

Frequently Asked Questions

Everything women on a fertility journey want to know before trying high-TQ black cumin seed oil.

Will this interfere with letrozole, Clomid, or gonadotropins?

No. Thymoquinone works on the NF-κB inflammatory cascade — a completely different system than ovulation-induction medications. Letrozole and Clomid work on estrogen signaling. Gonadotropins act on follicle-stimulating hormone directly. They target different pathways. Safe to take alongside all three, as well as metformin and inositol.

How long before I notice a difference?

Most women notice sleep and energy shifts within the first 2–3 weeks. Cycle-related changes — regularity, flow, OPK patterns — typically appear around weeks 6–8. The clinical trial measured significant improvements at 16 weeks. We recommend committing to at least 90 days of consistent daily use before evaluating results.

Can I take this during IUI or IVF cycles?

Many of our customers take Loomi during IUI prep and IVF stim cycles. Thymoquinone targets an inflammatory pathway — it does not interfere with hormonal stimulation protocols. That said, every IVF protocol is different. We always recommend confirming with your reproductive endocrinologist before adding anything to a medicated cycle.

Can I take this with inositol, CoQ10, and prenatals?

Yes — and they complement each other. Inositol improves insulin signaling at the cellular level. CoQ10 supports mitochondrial function. Prenatals provide essential micronutrients. Thymoquinone suppresses the NF-κB inflammatory cascade upstream of all of these. They work on different parts of the same system. Many of our customers take all four together.

Where is your black seed oil sourced from?

Our Nigella sativa is sourced from the regions where it has been traditionally cultivated for centuries — primarily Egypt and Turkey, where the soil and climate produce the highest natural thymoquinone concentrations. The oil is cold-pressed at the source to preserve the active compound, then formulated, encapsulated, and third-party tested in the USA. Every batch is verified to meet our 2% TQ standardization before it ships.

How is this different from the black seed oil at my grocery store?

Most generic black seed oil contains less than 1% thymoquinone — the active compound behind the clinical results. Ours is standardized to 2% TQ, verified by third-party testing. The concentration matters. It's the difference between drinking grape juice and taking the active compound.

What is your return policy?

90-day money-back guarantee. The clinical trial ran for 16 weeks — we give you 90 days so you have time to take it consistently and see how your body responds. If you're not satisfied, contact us for a full refund. No questions asked.

Black Cumin Seed Oil

Clinically Studied for the Pathways Most Fertility Protocols Miss

Nigella sativa has been used for thousands of years across the Middle East, North Africa, and South Asia for hormonal and inflammatory conditions. But tradition alone isn't why we're here.

In 2024, researchers published a randomized controlled trial examining Nigella sativa's effect on the inflammatory environment that disrupts hormonal signaling. After 16 weeks, participants showed improved hormonal balance, more regular menstrual cycles, and measurable changes in ovarian morphology — the upstream markers that fertility protocols rely on but rarely address directly.

"Nigella sativa demonstrated comparable efficacy to medroxyprogesterone in improving menstrual regularity, hormonal balance, and ovarian morphology."
— Journal of Ovarian Research, 2024

Added Loomi underneath my inositol about four months ago. My inositol had completely plateaued for six months. The plateau broke within eight weeks. Same dose of everything else. Something about addressing the inflammation layer unlocked what was already in my stack.

"It works but the wait is brutal when you're TTC."
I didn't notice anything until about week six which felt like forever when every month matters. Month three is when I actually saw my cycle change. Just be patient with it but I understand how hard that is on a fertility timeline.

"I wish they had a bigger bottle option."
The capsules are fine but I wish they had a bigger bottle option. 60 capsules is only a one month supply and I'd rather just buy three months at once instead of reordering. Especially when you're already juggling prescriptions and other supplements.

Took about five weeks before I felt any difference at all. I almost gave up at week three. My sleep improved first then eventually my cycles started shortening. It's working but when you're trying to conceive the wait is emotionally exhausting.

Helped my cycles and my bloating but didn't do much for the fatigue I've had since coming off birth control. Still taking it because my period has been regular for the first time in years, but I was hoping for more on the energy side.
