Discover the science, health benefits, and practical tips for maximising sulforaphane—nature's potent phytonutrient.
Broccoli microgreens are a powerhouse of nutrition, particularly known for their high sulforaphane content.
Whether you’re a health-conscious individual or exploring the joys of growing your own microgreens, this guide provides in-depth insights into sulforaphane, broccoli raab, and calabrese.
Learn how to grow, use, and benefit from these vibrant greens while embracing the advantages of microgreens growing kits and other supplies.
Understanding Sulforaphane
Definition and Natural Sources
Sulforaphane, a remarkable phytonutrient, is primarily found in cruciferous vegetables like broccoli, cauliflower, and cabbage.
Its highest concentrations are in broccoli sprouts and microgreens.
Sulforaphane is activated when glucoraphanin, a compound in these plants, interacts with the enzyme myrosinase—a reaction triggered by chopping or chewing.
“Sulforaphane is one of the most potent, naturally occurring anti-carcinogens.” — Dr. Rhonda Patrick
Health Benefits and Mechanisms
Sulforaphane supports health in multiple ways:
- Cancer Prevention: Neutralises carcinogens and activates detoxification enzymes.
- Anti-Inflammatory Effects: Suppresses inflammation, reducing risks of chronic diseases.
- Cardiovascular Support: Protects blood vessels and promotes arterial health.
- Anti-Aging: Activates proteins that slow cellular aging and repair damage.
Key Fact: Studies show that sulforaphane can reduce the risk of several cancers, including prostate, breast, and colon cancer, by up to 50%.
Broccoli Microgreens: An Overview
What Are Broccoli Microgreens?
Broccoli microgreens are tender, young plants harvested at 10-14 days.
They offer concentrated nutrition, including sulforaphane, vitamins, and minerals.
Sulforaphane Content in Broccoli Stages
Broccoli microgreens and sprouts are superior sources of sulforaphane compared to mature broccoli.
The following table outlines sulforaphane and nutrient content across different growth stages:
| Stage | Sulforaphane (mg/100g) | Vitamin C (mg/100g) | Vitamin K (mcg/100g) | Folate (mcg/100g) |
|---|---|---|---|---|
| Broccoli Sprouts | 5 to 60 mg | 89.2 mg | 140 mcg | 63 mcg |
| Broccoli Microgreens | 10 to 50 mg | 117 mg | 130 mcg | 108 mcg |
| Mature Broccoli | 0.5 to 18 mg | 89.2 mg | 101 mcg | 63 mcg |
The data highlights that broccoli microgreens offer a more concentrated form of sulforaphane and essential nutrients compared to mature broccoli.
Broccoli Microgreens Nutrition
Nutritional Highlights
Broccoli microgreens are loaded with essential vitamins and minerals, including:
- Vitamin C: 117 mg/100g—boosts immune health.
- Vitamin K: 130 mcg/100g—supports blood clotting and bone health.
- Folate: 108 mcg/100g—essential for cell regeneration.
Key Fact: Microgreens can offer up to 100 times the sulforaphane content of mature broccoli while retaining a rich vitamin profile.
Health Benefits
Their high antioxidant content combats oxidative stress, improving cardiovascular and metabolic health. Regular consumption is linked to reduced risks of chronic diseases.
Sulforaphane in Clinical Research
Clinical studies, such as the ESCAPE trial funded by Cancer Research UK, have explored sulforaphane’s benefits for promoting prostate health and overall wellness.
The trial used freeze-dried broccoli sprout preparations and highlighted the compound’s potential, though further research is required to establish definitive outcomes.

Health Benefits of Sulforaphane
Evidence-Based Effects
- Cancer Prevention: Activates detox pathways to neutralise carcinogens. Studies indicate that regular consumption of sulforaphane-rich foods can cut cancer risks by up to half.
- Diabetes Management: Lowers blood sugar and improves insulin sensitivity.
- Brain Health: Improves cognitive function and reduces symptoms of depression and anxiety.
Clinical Insight: “Sulforaphane improved behavioural symptoms in young autistic individuals in a Johns Hopkins University study.”
