Like Eating 5 Heads of Broccoli with Your Morning Coffee

Imagine the most powerful compound in a head of broccoli, concentrated into one small, potent capsule for daily support.

That compound is sulforaphane— a naturally occurring phytochemical known to support the body’s detoxification pathways, promote a healthy inflammatory response, and help maintain overall cellular function.*

Sulfora delivers a clinically relevant dose of activated sulforaphane, roughly equivalent to what you'd find in five heads of broccoli.*

No sprouting, or juicing required. Just daily, science-backed support for detox, immune balance, antioxidant defenses, and more — rooted in nature and validated by modern research.*

Your Armor Against Everyday Toxins

From microplastics found in food and water to air pollution on your morning commute, our bodies are constantly exposed to low-level toxins. Sulforaphane is clinically shown to activate detoxification enzymes — particularly through the Nrf2 pathway — that help neutralize and eliminate these harmful compounds at the cellular level.

Everyday Stressors Sulforaphane May Help You Detox:

Microplastics

Found in food, water, and air, microplastics can trigger oxidative stress and disrupt hormonal balance.


Sulforaphane activates glutathione-related enzymes that assist in mitigating plastic-associated oxidative damage and supporting cellular resilience.*

A person wearing clear gloves holds a handful of colorful plastic fragments and sand, highlighting pollution and environmental concerns.
BPA (Bisphenol A)

Present in plastic containers and receipts, BPA is a well-known endocrine disruptor.


Sulforaphane modulates genes responsible for xenobiotic metabolism and may help mitigate BPA-induced oxidative stress through its Nrf2-activating role.*

Plastic bottles and debris float underwater with sunlight filtering through, highlighting the pollution and environmental impact of plastic waste in the ocean.
Diesel Exhaust & Air Pollution

Airborne toxins, including fine particulate matter, are linked to inflammation and chronic disease.

Sulforaphane enhances cellular defense by upregulating phase II detox enzymes and antioxidant genes via Nrf2 activation.*

Factory smokestacks emit thick smoke into a yellow-orange sky at sunset, with dense steam and frost-covered ground in the foreground, highlighting industrial air pollution.
Heavy Metals (e.g. mercury, arsenic)

These accumulate in tissues and impair nervous system and immune function.

Sulforaphane shows promise in protecting against heavy metal toxicity by enhancing glutathione synthesis and related detox pathways.*

Pesticide Residues

Common in non-organic produce, pesticides stress the liver and nervous system.

Sulforaphane stimulates critical detoxification pathways (like glutathione-S-transferases) that assist in metabolizing and clearing pesticide compounds.*

Natural Vs Stabilized Sulforaphane

A diagram of a human torso shows broccoli seed extract (glucoraphanin) and mustard seed extract (myrosinase) entering the body, combining in the stomach to create sulforaphane.

Science shows natural activation in the gut is the only reliable way.

And not all sulforaphane supplements deliver what they promise. In fact, a truly science-backed formula shouldn’t contain sulforaphane itself at all.

Many products rely on something they call “stabilized sulforaphane.”

It sounds impressive, but the reality is that sulforaphane in its pre-formed state is highly unstable, and even "stabilized sulforaphane" often breaks down before your body ever has a chance to absorb it.

We take a radically different approach, supported by decades of research:

Not delivering sulforaphane directly, but rather sulforaphane precursors — glucoraphanin from broccoli seeds and myrosinase from mustard seeds — and allowing your body to activate it naturally during digestion.

That’s how sulforaphane is produced when you eat raw broccoli sprouts or other cruciferous vegetables, and it’s the most reliable way to achieve real biological activity.

Because with sulforaphane, it’s not just about what’s in the capsule, it’s about what your body can actually use.

Everyday Protection Starts at the Cellular Level

What is Sulforaphane (and Why Does it Matter)?

How Does Sulforaphane Impact Brain Health?

Can Sulforaphane Help Detox Toxins like Pollution, Smoke, & Alcohol?

Formulated in collaboration with sprout nutrition expert Doug Evans.

Doug Evans has spent over a decade promoting the powerful nutrition of sprouts — especially broccoli sprouts — for their dense phytonutrient content and role in everyday wellness. As the author of The Sprout Book and a well-known voice in sulforaphane education, he’s inspired thousands to incorporate sprouts into their daily routines.

But Doug recognized a challenge: most people aren’t growing their own.

To solve that, he teamed up with COMPLEMENT, and together, with guidance from globally recognized sulforaphane research scientists, we spent the last year identifying the most potent extracts to ensure proper sulforaphane activation and deliver a formula that mirrors the best of nature.

The result? A daily dose of activated sulforaphane, equal to what you'd get from eating multiple heads of broccoli, in a capsule you can take with your morning coffee.

DV may be higher or lower based on individual needs. † Daily Value not established. Other Ingredients: Hypromellose (capsule), rice flour, and magnesium stearate.

What is the suggested use?

Take two capsules daily with or without food. Morning is ideal, but consistency matters more than timing.

Is Sulfora vegan?

Yes. Sulfora is 100% vegan, non-GMO, gluten-free, and made without soy, dairy, or common allergens.

How is Sulfora different from other sulforaphane supplements?

Most supplements use “stabilized sulforaphane,” which often breaks down before your body can use it. Sulfora uses the clinically backed combo of glucoraphanin and myrosinase to generate active sulforaphane during digestion, where it matters.*

How much sulforaphane is in each serving?

Each daily serving is designed to generate the equivalent amount of activated sulforaphane you’d get from eating up to five heads of raw broccoli, without the prep or the volume!*

Why not just eat broccoli sprouts?

Broccoli sprouts are an incredible source of sulforaphane precursors, but the actual sulforaphane you get can vary widely depending on how the sprouts are grown, stored, and prepared. Heat, seed quality, and even how long they sit in your fridge all affect potency.

Sulfora takes the guesswork out by combining broccoli seed extract (a source of glucoraphanin) with mustard seed extract (a source of myrosinase) under controlled conditions. Each batch is tested for purity and potency so you can count on consistent sulforaphane activity, every time.*

How fast will I notice anything?

Some people report feeling subtle changes — such as digestive comfort or overall well-being — within the first couple of days or weeks. For others, the benefits are more gradual and may be less noticeable day-to-day.

Because sulforaphane supports your body’s natural detoxification and antioxidant defenses, its effects often happen beneath the surface. The key is consistent daily use to help your body maintain those internal pathways of protection over time.*

Can I take it with coffee or food? What about medications?

Sulfora can be taken with or without food, though many people prefer to take it with a meal for ease of digestion. It’s generally fine to take alongside your morning coffee.

If you are taking prescription medications or other supplements, we recommend checking with your healthcare professional before adding any new product to your routine.

To maximize absorption and comfort, try taking Sulfora around the same time each day with water or a meal.*

How is Sulfora tested for quality?

Every batch is third-party tested for potency, purity, and safety. We even publish the test results here for everyone to see!

Is it safe to take long-term?

Sulforaphane has been studied extensively and is considered safe for long-term daily use. As always, consult your healthcare provider if you’re pregnant, nursing, or managing a medical condition.

What if I don’t like it?

As always, we offer our game-changing 100-day money-back guarantee. If you’re not satisfied, we’ll issue a full refund. No questions asked.

Is it eligible for HSA/FSA reimbursement?

Yes. Through our partnership with Truemed, you can use your HSA or FSA funds. Just complete a short survey after purchase to get started.
