Introduction
BrocElite Plus is a broccoli-derived dietary supplement from Mara Labs that provides stabilized sulforaphane directly in capsule form. Unlike many broccoli supplements that supply glucoraphanin and depend on myrosinase to produce sulforaphane after ingestion, BrocElite Plus is formulated to deliver sulforaphane itself.
Sulforaphane has attracted substantial scientific interest because it activates cellular defense pathways, particularly the Nrf2 pathway. Human research has investigated sulforaphane in areas including antioxidant defenses, detoxification enzymes, inflammation, metabolic health, and cancer-related biomarkers. However, most clinical evidence involves broccoli sprouts, broccoli extracts, or other sulforaphane formulations—not BrocElite Plus specifically.

What Is BrocElite Plus?
BrocElite Plus is a one-capsule-per-day sulforaphane supplement. The current 30-capsule label provides 5 mg stabilized sulforaphane plus 325 mg of broccoli seed complex. The complex contains PEITC, iberin, BITC, and AITC, according to Mara Labs.
The product is vegan, gluten-free, and marketed as containing no fillers. Mara Labs also states that each batch undergoes internal and third-party testing for sulforaphane content and that the company tests for glyphosate, heavy metals, and contaminants. These are manufacturer quality claims rather than independent verification presented in the product review itself.
How It Works
Sulforaphane is an isothiocyanate produced naturally from glucoraphanin in cruciferous vegetables. It can modify the Keap1-Nrf2 system, allowing Nrf2 to activate genes involved in antioxidant and cellular defense responses.
BrocElite Plus takes a different delivery approach from glucoraphanin-based supplements. Instead of requiring conversion by myrosinase after consumption, Mara Labs states that the capsule contains stabilized sulforaphane directly. Human research supports the broader concept that sulforaphane formulation and bioavailability matter because conversion from glucoraphanin can vary considerably.
BrocElite Plus Key Ingredients
Stabilized Sulforaphane – 5 mg
Sulforaphane is the primary active compound in BrocElite Plus. The current 30-capsule product provides 5 mg per capsule.
Human research shows that sulforaphane can activate antioxidant and cellular defense pathways, but clinical results vary depending on the population, formulation, and outcome measured. A recent review identified 84 registered sulforaphane clinical trials, of which 39 had published results, while noting small sample sizes and inconsistent outcomes.
Study: PubMed – Sulforaphane clinical trials and mechanisms
Broccoli Seed Complex – 325 mg
The Plus formula includes a 325 mg broccoli seed complex containing PEITC, iberin, BITC, and AITC. Mara Labs describes these compounds as structurally related to sulforaphane and says they work alongside it to influence Nrf2-related activity.
The evidence for these individual compounds is not as extensive as the research base surrounding sulforaphane itself. Therefore, it is more appropriate to view the broccoli seed complex as a supporting part of the formulation rather than assigning it separate, proven clinical benefits.
PEITC
Phenethyl isothiocyanate, or PEITC, is an isothiocyanate associated with cruciferous vegetables such as watercress. Mara Labs specifically identifies PEITC as the ingredient that distinguishes BrocElite Plus from its standard BrocElite formula.
Laboratory research has investigated PEITC for antioxidant, detoxification, and cancer-related mechanisms, but human clinical evidence is much less developed than the evidence for sulforaphane.
Iberin, BITC & AITC
Iberin, benzyl isothiocyanate (BITC), and allyl isothiocyanate (AITC) are additional isothiocyanates included in the broccoli seed complex. These compounds have been studied primarily in laboratory and mechanistic research.
Because the current label combines them within a 325 mg complex without individual quantities, it is not possible to determine the dose of each compound or directly compare the formula with individual experimental studies.
What Does the Research Say About Sulforaphane?
One of the most important issues with sulforaphane supplements is bioavailability.
Glucoraphanin is a precursor rather than sulforaphane itself. Myrosinase converts glucoraphanin into sulforaphane, but the efficiency of that conversion can vary. Human research has demonstrated substantially different sulforaphane exposure depending on whether people consume broccoli sprouts, glucoraphanin-rich products, or preparations containing active myrosinase.
A randomized crossover study found that myrosinase treatment substantially influenced sulforaphane exposure after broccoli sprout extract consumption.
Study: PubMed – Sulforaphane absorption from broccoli sprouts and extract
A separate human study comparing stabilized sulforaphane preparations found that stabilized formulations could remain biologically active and bioavailable, although the study evaluated formulations different from BrocElite Plus.

BrocElite Plus Benefits
Based on the formulation and available sulforaphane research, BrocElite Plus may:
- Activate cellular antioxidant-defense pathways through sulforaphane.
- Support the body’s natural phase II detoxification processes.
- Promote antioxidant defenses against oxidative stress.
- Influence inflammatory and cellular signaling pathways studied in human research.
- Provide a consistent stated amount of stabilized sulforaphane without relying on dietary conversion of glucoraphanin.
These are potential physiological benefits. They should not be interpreted as proof that BrocElite Plus prevents disease, removes specific toxins, treats inflammation, or improves longevity.

Comparison Table With Alternatives
| Product | Sulforaphane Approach | Format | Current Listed Price |
|---|---|---|---|
| BrocElite Plus | 5 mg stabilized sulforaphane + broccoli seed complex | Capsule | $59.95 / 30 caps |
| Avmacol Extra Strength | Glucoraphanin + active myrosinase + maitake | Tablet | $65.99 / 75 tablets |
| Jarrow BroccoMax | Broccoli seed extract + active myrosinase | Delayed-release capsule | $25.99 listed |
| Broccoli Sprouts | Natural glucoraphanin + myrosinase | Food | Varies |
Avmacol Extra Strength uses a glucoraphanin-plus-myrosinase strategy rather than providing pre-formed sulforaphane. Its current official page lists 25 mg of a proprietary glucoraphanin/myrosinase blend per tablet and a 75-count package at $65.99.
Jarrow BroccoMax also uses broccoli seed extract with active myrosinase to generate sulforaphane after ingestion. Its current official page lists a $25.99 price and recommends two delayed-release capsules daily.
The comparison therefore comes down partly to delivery strategy: BrocElite Plus supplies stabilized sulforaphane directly, while products such as Avmacol and BroccoMax provide precursor glucoraphanin plus myrosinase to generate sulforaphane in the body.
Customer Reviews
The current 30-capsule BrocElite Plus page displays a 4.4/5 rating from 126 reviews. Customer comments include reports of clearer thinking, feeling more energetic, and reduced general discomfort.
Some reviewers also acknowledge that they cannot determine whether the product has produced a measurable difference. That distinction is important because testimonials can describe individual experiences but cannot establish efficacy.
Mara Labs also publishes customer testimonials on its product page, including reports of vivid dreams and changes in perceived energy or mental clarity. These remain anecdotal observations rather than controlled clinical outcomes.
Who Should Use BrocElite Plus?
BrocElite Plus may be relevant to adults who:
- Want a broccoli-derived sulforaphane supplement.
- Prefer a product that states a specific amount of stabilized sulforaphane.
- Want to avoid relying on dietary conversion of glucoraphanin.
- Are interested in cellular antioxidant and defense pathways.
- Prefer a once-daily capsule.
It is better viewed as a general wellness supplement than as a treatment for a specific disease.
Who Should Avoid or Discuss It With a Clinician?
People should discuss BrocElite Plus with a healthcare professional before use if they:
- Are pregnant or breastfeeding.
- Take prescription medications.
- Have a chronic medical condition.
- Are undergoing cancer treatment.
- Are preparing for surgery.
- Have experienced significant gastrointestinal reactions to cruciferous vegetables or concentrated broccoli extracts.
Mara Labs specifically advises consultation with a physician during pregnancy or breastfeeding. More generally, supplement use should be reviewed when medications or significant medical conditions are involved.
Side Effects & Safety
Human studies of broccoli sprouts and sulforaphane-containing preparations generally suggest reasonable short-term tolerability, but side effects can occur.
A phase I randomized study of broccoli sprout glucosinolates and isothiocyanates found the preparations were generally tolerated by healthy volunteers.
A newer phase I trial involving a different stabilized sulforaphane formulation reported mostly mild gastrointestinal adverse events. Because that product used synthetic stabilized sulforaphane at much higher experimental doses, its safety findings should not be directly applied to BrocElite Plus.
Potential issues may include:
- Gas or digestive discomfort
- Nausea or stomach upset
- Changes in bowel habits
- Strong taste or odor sensitivity
Mara Labs recommends taking BrocElite Plus with food and provides storage guidance intended to preserve product stability.
Is BrocElite Plus Clinically Proven?
This requires a distinction between ingredient research and product-specific evidence.
Sulforaphane itself has been tested in numerous human clinical studies. Research has examined biomarkers related to antioxidant defense, detoxification, inflammation, cancer biology, metabolic health, and other outcomes.
For example, a randomized trial involving men with recurrent prostate cancer found that sulforaphane-rich broccoli sprout extracts were safe and produced a statistically significant change in PSA doubling time, but the primary endpoint—a ≥50% PSA decline—was achieved by only one participant. The researchers concluded that additional research was needed.
Another randomized trial in men undergoing prostate biopsy found changes in prostate tissue biomarkers after broccoli sprout extract supplementation.
Neither study tested BrocElite Plus.
Therefore, it would be inaccurate to describe BrocElite Plus as clinically proven to prevent cancer, treat inflammation, detoxify the body, or improve brain health.

BrocElite Plus is a broccoli-derived dietary supplement containing stabilized sulforaphane and a broccoli seed complex. It is marketed primarily for cellular antioxidant, detoxification, and general wellness support.
2. How much sulforaphane is in BrocElite Plus?
The current 30-capsule version provides 5 mg of stabilized sulforaphane per capsule.
3. What is the “Plus” in BrocElite Plus?
The Plus refers to the broccoli seed complex containing PEITC, iberin, BITC, and AITC. Mara Labs says these compounds complement the stabilized sulforaphane.
4. Does BrocElite Plus contain glucoraphanin?
The current label lists stabilized sulforaphane rather than glucoraphanin as its primary active ingredient. Mara Labs specifically distinguishes BrocElite from glucoraphanin-based broccoli supplements.
5. Does sulforaphane activate Nrf2?
Sulforaphane is known to interact with the Keap1-Nrf2 pathway and can stimulate antioxidant and cellular defense gene expression. Human studies have demonstrated biological effects, although clinical outcomes vary by condition and formulation.
6. Can BrocElite Plus detox the liver?
The manufacturer markets BrocElite Plus for supporting natural detoxification processes. Sulforaphane can influence phase II detoxification enzymes, but this does not mean the supplement “cleanses” or removes all toxins from the liver.
7. Can BrocElite Plus prevent cancer?
No clinical evidence establishes BrocElite Plus as a cancer-prevention treatment. Sulforaphane is being investigated for chemopreventive mechanisms, but human evidence remains insufficient to make that claim for this product.
8. Can BrocElite Plus reduce inflammation?
Sulforaphane influences several inflammatory and oxidative-stress pathways, and some human studies have measured changes in inflammatory biomarkers. However, this does not establish BrocElite Plus as a treatment for chronic inflammation.
9. How should BrocElite Plus be taken?
The current 30-capsule product recommends one capsule daily with food.
10. How much does BrocElite Plus cost?
The current one-time price for 30 capsules is $59.95, while a subscription price of $50.96 is displayed. Multi-bottle packages are also available.
Final Verdict
BrocElite Plus has a scientifically interesting formulation because it provides a stated amount of stabilized sulforaphane directly rather than relying exclusively on the conversion of glucoraphanin into sulforaphane. Human research confirms that sulforaphane is biologically active and can influence Nrf2-related antioxidant and cellular defense pathways.
The strongest point in the formula is therefore its delivery strategy and label specificity. The current 30-capsule product provides 5 mg of stabilized sulforaphane per capsule, along with 325 mg of a broccoli seed complex. Mara Labs also states that its batches undergo third-party testing for sulforaphane content.
The main limitation is evidence. I did not identify a published randomized controlled trial testing BrocElite Plus itself. Most available clinical research involves sulforaphane-rich broccoli sprouts, broccoli extracts, glucoraphanin-plus-myrosinase preparations, or other stabilized formulations.
The research also does not support treating BrocElite Plus as a proven cancer-prevention product, liver detox treatment, anti-inflammatory medication, or longevity intervention. Those claims go beyond what can reasonably be concluded from current human evidence.
Overall, BrocElite Plus is best described as a specialized sulforaphane supplement for general cellular antioxidant and defense support. Its direct stabilized-sulforaphane approach is scientifically relevant, but consumers should distinguish the promising research on sulforaphane from clinical proof of the finished BrocElite Plus product.
