Broccoli Extract Sulforaphane

 

Broccoli extract (Standardized to ≥1% Sulforaphane) is a high-potency bioactive ingredient derived from Brassica oleracea, widely recognized for activating the cellular Nrf2 antioxidant pathway. While market demand is surging, brand formulators frequently encounter critical supply chain bottlenecks: rapid bioactivity degradation, poor myrosinase conversion rates, and inconsistent batch-to-batch potency.

 

At Fruiterco, we solve these formulation challenges through proprietary low-temperature extraction and stabilization processes. Each batch is HPLC-verified to ensure ≥1.0% active sulforaphane, >95% stability retention over 24 months, and full water solubility-delivering reliable, clean-label performance for dietary supplements, functional beverages, and nutricosmetics.

1. Cellular-Level Endogenous Antioxidant Defense and Anti-Aging

Sulforaphane powder, an active compound found in broccoli, is one of the most potent natural activators of the Nrf2 (nuclear factor erythroid 2-related factor 2) pathway known to date. Unlike exogenous, "consumable" antioxidants such as vitamin C, sulforaphane triggers the expression of over 200 protective genes within human cells, leading to a sustained increase in the levels of endogenous antioxidant enzymes-including glutathione (GSH) and superoxide dismutase (SOD)-directly within the cells.

 

2. Liver Detoxification and the Metabolism of Environmental Toxins

It potently induces the activity of Phase II detoxification enzymes in the liver-such as quinone reductase (NQO1) and glutathione S-transferase (GST)-thereby accelerating the conversion of fat-soluble toxins (including air pollutants like PM2.5, benzene, heavy metals, alcohol metabolites, and food additives) into water-soluble substances that can be excreted from the body.

 

3. Anti-inflammatory, Soothing, and Immune Homeostasis Regulation

By inhibiting pro-inflammatory signaling pathways-such as the NF-κB pathway-and downregulating the release of inflammatory mediators (e.g., IL-6, TNF-α), this process helps alleviate the "chronic low-grade inflammation" often experienced by modern individuals due to factors like high-sugar and high-fat diets, stress, and sleep deprivation.

 

4. Gastrointestinal Microbiota and Mucosal Protection

Numerous clinical studies have demonstrated that sulforaphane extract exhibits significant inhibitory activity against Helicobacter pylori (H. pylori)-including certain antibiotic-resistant strains-while simultaneously protecting the gastric mucosa from oxidative damage and maintaining the integrity of the intestinal barrier.

 

 

1. Applicable End-Product Formats

• Dietary Supplements (Hard Capsules/Tablets): The most common application.
• Functional Foods and Beverages (Powdered Drink Mixes/Liquid Supplements/Gummies): Requires deodorized and water-soluble-optimized grades, ideal for daily wellness products, anti-glycation, and antioxidant-focused beverages.
• Functional Skincare (Topical Serums/Creams): Beyond oral consumption, high-purity broccoli sprout extract is frequently used as a cosmetic ingredient to address photoaging, soothe sensitive or reddened skin, and provide protection against urban environmental pollutants.
• Foods for Special Medical Purposes (FSMP) and Pet Nutrition: Due to its high safety profile and anti-inflammatory properties, its use in premium anti-aging and liver-support supplements for pets is also growing rapidly.

 

2. Recommended Combination Strategies

• High-End Cellular Anti-Aging: Broccoli Extract + Ergothioneine + Astaxanthin / Collagen Peptides
• Liver Support Formula: Broccoli Extract + Milk Thistle Extract (Silybin) + Curcumin + Inositol
• Gastrointestinal Soothing Regimen: Broccoli Extract + Lactobacillus reuteri + Lion's Mane Mushroom Extract

 

 

Q: What is the difference between glucoraphanin and sulforaphane?

A: Glucoraphanin is the natural precursor to sulforaphane and is highly stable. Once it enters the human digestive tract, it is efficiently converted into active sulforaphane through the catalytic action of the enzyme myrosinase.

 

Q: How do you determine the content of active ingredients? What kind of third-party test reports can you provide?

A: We use the internationally recognized HPLC method for the precise quantification of sulforaphane content. Each batch is accompanied by a Certificate of Analysis (COA) upon shipment. Additionally, we can provide test reports from authoritative third-party organizations (such as SGS or Eurofins) covering pesticide residues, heavy metals, microbiological contaminants, aflatoxins, and residual solvents.

 

Q: What are the product's solubility and shelf-life stability like?

A: Our broccoli extract disperses and dissolves rapidly in water at room temperature, resulting in a clear, transparent solution with no sedimentation-making it ideal for liquid beverages and instant powdered drink mixes. When stored in a sealed, light-protected, cool, and dry environment (≤25°C), the product has a shelf life of up to 24 months. Accelerated stability testing confirms that over 95% of the active ingredients are retained.

 

Q: What is the Minimum Order Quantity (MOQ)? Do you offer custom specifications and free samples?

A: The MOQ is 1 kg, packaged in an aluminum foil bag. For qualifying B2B clients, we provide 10g R&D samples free of charge, along with relevant technical documentation (TDS/MSDS/COA). We also offer customization services to meet specific concentration or formulation ratio requirements based on your needs.
