    OK I'm a believer

    Inositol, spearmint tea, berberine. Did it all. Month three and my cycle showed up on its own for the first time since I came off birth control in 2023. I have not shut up about it.

    It finally clicked

    Nobody ever explained WHY I wasn't ovulating. It was always here's metformin, lose 15 pounds, come back in six months. The inflammation piece was the first time it made sense as a system instead of a list of things wrong with me.

    My doctor shrugged

    18 months. Two rounds of letrozole, both failed. Every appointment ended with "PCOS is just complicated." Started this in February. Three cycles in a row now and I hadn't had three in a row in four years.

    The strips did something

    Peed on OPKs for two years and got nothing. Two solid lines last month. That's it, that's the review.

    Not a miracle but

    Almost sent it back after month one. Around week 7 my jaw stopped breaking out and the chin hairs slowed enough that I'm plucking weekly instead of daily. Cycle still isn't perfect. But things are moving and I'll take moving over stuck.

Why Everything Else Fails

Most PCOS fixes only chase one symptom at a time. None of them touch the real cause: hidden inflammation. That inflammation is what throws off your hormones in the first place. High-TQ black seed oil is made to calm that root cause instead.

How It Works

Black seed oil has a special part called TQ. TQ helps calm the inflammation that messes with your hormones. Our oil is cold-pressed to keep the TQ strong. Most women feel small changes in a few weeks, then more over time.

How Long Will It Take To See Results?

Most women notice sleep and energy changes within the first 2-3 weeks. Skin and cycle improvements typically follow around weeks 6-8.

Give it a full 90 days for the best picture of what it can do — that's why we offer a 90-day money-back guarantee.

Can I Take It With Other Supplements Or Medications?

Yes. Loomi is designed to work alongside your current routine — not replace it. Women take it with inositol, metformin, letrozole, CoQ10, prenatals, and more.

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

Is All Black Seed Oil The Same?

No. Most black seed oil is made with high heat, which destroys the good part called TQ. Ours is cold-pressed, so the TQ stays strong. That's why ours works and cheap ones don't.

Ingredients

One ingredient. Nothing to hide behind.

Active Ingredient Black Seed Oil (Nigella sativa)
Standardized To 2% Thymoquinone (TQ)
Strength 500 mg per capsule
Count 60 capsules

Cold-pressed and standardized to a guaranteed 2% thymoquinone — the active compound that actually matters. No fillers, no proprietary-blend hiding, no padding the label with a dozen "support" ingredients at doses too small to count.

"clear skin and shorter cycles in three months"

Been taking this with breakfast for about three months. My jawline cleared up around week five and my last two cycles came at 33 and 31 days. Haven't had cycles that short in years.

"my inositol finally works now"

Added this underneath my inositol about four months ago. My inositol had plateaued for like six months. Plateau broke within eight weeks. Same dose of everything else.

Thymoquinone and PCOS - how it reduces inflammation and balances hormones
How Does It Work for PCOS?

PCOS starts with inflammation that gets stuck "on." That drives insulin resistance, high testosterone, and the symptoms you actually deal with — acne, hair loss, weight gain, irregular cycles.

Thymoquinone, the active compound in black seed oil, works on that stuck switch — so the rest can calm down too.

Targets the root — not just the symptoms
Backed by a 2024 clinical trial on 114 women
Works alongside your current meds and supplements
Cold-Pressed Black Seed Oil
Address Your PCOS at the Source
Loomi delivers thymoquinone standardized to 2% potency. A 2024 study in the Journal of Ovarian Research found it works by modulating the NF-κB inflammatory pathway, targeting the upstream environment that drives PCOS symptoms.*

Frequently Asked Questions

Is This For Me?

If you have PCOS and nothing you've tried has fully worked — this was made for you. It works alongside your current supplements and medications, not instead of them.

What Are the Benefits?

Loomi targets the inflammatory root underneath PCOS. Women report shorter cycles, calmer skin, slower facial hair growth, less bloating, steadier energy, better sleep, and reduced cravings — because it addresses the one root driving all of them.

Recommended Usage

Take one capsule daily with food. That's the entire routine.

Most women notice sleep and energy changes within 2-3 weeks. Skin and cycle improvements typically follow around weeks 6-8. We recommend giving it a full 90 days for the best results.

Where Does Black Seed Oil Come From?

Black seed oil comes from Nigella sativa — a flowering plant native to Ethiopia and the Middle East. It's been used in traditional medicine for over 2,000 years.

The active compound that matters is thymoquinone (TQ). Loomi is cold-pressed from raw seed and standardized to a guaranteed 2.0% TQ — because heat destroys the compound, and most black seed oil on the shelf has almost none left by the time it's bottled.

What Is Loomi's Return Policy?

We offer a full 90-day money-back guarantee. No questions asked.

Try it for 90 days. If you're not happy with the results, contact us and we'll refund your purchase. We're confident enough in what this does that we'd rather you try it risk-free than never try it at all.

Common Questions

Frequently Asked Questions

Everything PCOS patients want to know before trying high-TQ black cumin seed oil.

Will this interfere with my birth control or metformin?

No. Thymoquinone works on the NF-κB inflammatory cascade. Birth control works on hormonal suppression. Metformin works on insulin sensitivity. They target completely different systems. Safe to take alongside both, as well as spironolactone and inositol.

How long before I notice a difference?

Many customers notice skin changes and reduced oiliness within 2-4 weeks. The clinical trial measured significant improvements in hormonal balance, ovarian volume, and cycle regularity at 16 weeks. We recommend committing to at least 8-12 weeks before testing labs.

Can I take this with inositol?

Yes — and they complement each other. Inositol improves insulin signaling at the cellular level. Thymoquinone suppresses the NF-κB inflammatory cascade upstream of insulin resistance. They work on different parts of the same problem. Many of our customers take both and report better results than either alone.

I'm trying to conceive. Is this safe?

Nigella sativa has been used for centuries and has a strong safety profile. The clinical trial was conducted on adolescents and showed improved hormonal balance and cycle regularity. However, we always recommend consulting your OB-GYN or reproductive endocrinologist before adding any supplement when actively trying to conceive.

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

The Only Compound Clinically Tested Head-to-Head Against a PCOS Drug

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 on 114 adolescents with PCOS. After 16 weeks, the Nigella sativa group showed reduced ovarian volume, lower testosterone, improved LH-to-FSH ratio, reduced hirsutism scores, and more regular menstrual cycles — comparable results to medroxyprogesterone, the standard pharmaceutical treatment.

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