Possible Benefits
Broccoli Powder contains sulforaphane and glucoraphanin, bioactive compounds that activate detoxification enzymes, provide antioxidant protection, and support cellular health.
- Helps support Detoxification & Cleansing by inducing phase II liver enzymes that neutralize carcinogens and toxins.
- May promote Immunity through immune-modulating effects of sulforaphane and upregulation of antioxidant enzymes.
- Supports Anti-Aging by protecting DNA and cellular structures from oxidative damage.
- Contributes to Heart Health by reducing inflammation and improving endothelial function.
Side Effects
Broccoli sprout extract is rich in sulforaphane for detox support, but mild effects can arise as phase II enzymes activate. Watch for:
- Possible mild gastrointestinal discomfort, bloating or mild diarrhea
- Occasional headache or lightheadedness during initial days
- Temporary mild body odor changes, sulfurous scent
- Rare allergic reactions, rash or itching
- Very mild changes in urine odor
Interactions

Studies
These studies provide scientific insights into Broccoli benefits:
A 2014 double-blind RCT in 50 young men with autism spectrum disorder found 50 µmol/day sulforaphane from broccoli sprout extract for 18 weeks improved behavior ratings .
A 2009 randomized crossover trial in 12 healthy smokers showed 250 mL/day broccoli sprout beverage for 7 days increased urinary excretion of benzene metabolites by 61 % versus placebo, indicating enhanced detoxification.
A 2017 RCT in 40 ragweed-allergic adults found 100 mL/day broccoli sprout homogenate for 14 days reduced nasal symptom scores by 38 % versus placebo , demonstrating anti-inflammatory effects.
Despite promising phytochemical content, no RCTs have evaluated broccoli or sulforaphane for glycemic control or cardiovascular endpoints in healthy adults.
