Research
Research indicates that SFN (Sulforaphane), a compound found in cruciferous vegetables like broccoli and Brussels sprouts, can influence several biological processes related to cell mutation.
- Chemoprevention: SFN may help prevent cancer by enhancing the body's detoxification of carcinogens and reducing oxidative stress and inflammation.
- Anticancer Effects (in lab/animal studies): In cell and animal models, SFN has been shown to Induce programmed cell death (apoptosis) in unstable-mutating cells. Arrest the cell cycle, which stops mutating cell proliferation. Inhibit the formation and self-renewal of cancer stem cells (CSCs), a subpopulation linked to tumor resistance and relapse. Suppress metastasis and angiogenesis (formation of new blood vessels that feed tumors). Modulate gene expression through epigenetic changes, such as inhibiting histone deacetylases (HDACs).
SFN as a Co-Adjuvant Therapy
A key area of research is using SFN to enhance the effectiveness of conventional therapies and potentially reduce their side effects.
- Chemosensitization: SFN can make mutating cells more sensitive to chemotherapy drugs like cisplatin, doxorubicin, and paclitaxel, potentially allowing for lower drug doses and reduced toxicity to normal cells.
- Combination with Radiation: Preclinical studies suggest that combining SFN with radiation therapy can enhance the anti-tumor effects while protecting healthy tissues from radiation-induced damage.
- Immune System Modulation: SFN may help remodel the tumor microenvironment to be more supportive of anti-tumor immunity, though its effects on T-cell function mean timing and dosage with immunotherapy agents needs careful consideration.
What is BROC?
What is BROC?
Each serving delivers 30mg of activated sulforaphane from proprietary broccoli seeds—the compound studied in thousands of trials for activating your body's natural detoxification system against body-damaging compounds.
We include the enzyme (myrosinase) that most supplements leave out, so your body actually absorbs it. Two capsules daily activates the cellular defense mechanisms that prevent DNA damage and neutralize body-damaging compounds.
Do I take this before chemo, during, or only after?
Do I take this before chemo, during, or only after?
You can take it BEFORE, DURING, and AFTER treatment. Research suggests sulforaphane works best when started before chemo begins—it builds cellular defenses so your body is protected when treatment hits. Continue through your full treatment cycle to support recovery between rounds. Many people continue after treatment ends for ongoing cellular protection during remission. Two capsules daily with breakfast, whenever you start.
✓ 2 capsules in the morning with food
✓ Best taken consistently
No taste, no prep, no hassle—just swallow with water and get on with your day. Each bottle contains a 30-day supply.

BROC Turns On Your Body's Advanced Defense System
Every day, carcinogens from food, air, and environment enter your body. Your cells have a defense system designed to neutralize these threats before they damage DNA—but it needs to be activated.
Decades of Clinical trials and Studies suggest that sulforaphane may activate the Nrf2 pathway, your cellular "cleanup crew." Research indicates this process works like this:
Without activation: Toxins enter → damage DNA → mutations accumulate → disease risk increases
With sulforaphane activation: Toxins enter → Nrf2 turns on detox enzymes → toxins neutralized → DNA stays protected

Tested by Independent Labs. Trusted by You.
We test every batch. Our competitors don't.
Third-party labs compare BROC against 21 leading sulforaphane supplements. The results are published: our proprietary seeds deliver 30mg of bioavailable sulforaphane—more than any product tested.
This is about activating the detoxification pathways that neutralize carcinogens. You deserve verified potency, not guesswork.
Thousands Of People Trust BROC

★★★★★
I live in Cancer Alley, Louisiana—2 miles from a chemical plant. Our town has one of the highest cancer rates in the state. Beat lung cancer two years ago but I'm still breathing the same air. Started BROC after reading it helps detoxify environmental toxins. Six months in, my energy is better and I feel like my body's finally fighting back against what's around me. This and a water filter are my best defense. Latest scan was clear.

★★★★★
I'm 62 and beat prostate cancer last year. The constant fear of recurrence was eating me alive. Started BROC three months ago after reading about the Nrf2 pathway and how it helps destroy abnormal cells. I can't know for certain if it's 'working,' but I finally feel like I'm doing something real to protect myself. My anxiety has dropped significantly because I'm taking action instead of just worrying about it coming back.

★★★★★
Breast cancer took my mom, aunt, and grandmother. At 44, I was diagnosed too. Started BROC during treatment after finding the sulforaphane research. My mom and aunt lost 30+ pounds during chemo. I lost maybe 10 and kept my appetite. My oncologist said I handled treatment remarkably well. Five months in—cancer-free now. I believe BROC helped my body fight back. This is my daily insurance policy against recurrence.

Frequently Asked Questions
Because it's not a drug. Pharmaceutical companies can't patent broccoli compounds, so there's no profit in promoting them. Medical schools teach drugs, not nutrition. The research exists—Johns Hopkins has been publishing it for 30 years. Your oncologist isn't hiding it from you; they just don't know it exists. Show them the studies. Most are genuinely interested.
Two capsules with breakfast. That's it. The sulforaphane is stabilized and combined with digestive-friendly ingredients. Most people report zero stomach issues—unlike chemo, which destroys your gut. If you can keep food down, you can take BROC.
Research suggests sulforaphane may actually ENHANCE chemo effectiveness, not interfere with it. That said, always inform your oncologist about any supplements. BROC is a food-derived compound—it's closer to eating broccoli than taking a drug. But your doctor should know everything you're taking.
No. We're not saying BROC prevents cancer or stops recurrence. What research suggests is that sulforaphane may help your body handle treatment better, protect healthy cells, and support cellular defense mechanisms. Cancer is complex. There are no guarantees. BROC is one tool—not a cure. Use it alongside your full treatment protocol, not instead of it.
