Liposomal Sulforaphane 4% is an innovative dietary supplement ingredient that encapsulates sulforaphane—the core bioactive compound extracted from broccoli seeds—within phospholipid bilayers using modern bio-nanotechnology. As a potent activator of the Nrf2 signaling pathway, natural sulforaphane exhibits outstanding benefits in cellular detoxification, free radical scavenging, and immune homeostasis maintenance. However, unencapsulated sulforaphane is highly susceptible to heat, light, and gastric acid, often leading to low stability and poor bioavailability.
By employing nano-liposomal carrier technology, the particle size is maintained within the 100–300 nm range. This structure protects the active compound from digestive degradation while promoting rapid uptake through intestinal cellular membranes. The ingredient is presented as a yellow powder with excellent flowability, retaining its natural characteristic aroma while guaranteeing a standardized active sulforaphane content of ≥ 4.0% via HPLC testing. Whether you are formulating premium anti-aging supplements, liver detox capsules, or next-generation cellular health beverages, our Liposomal Sulforaphane powder is the ideal choice for brands seeking maximum absorption and proven efficacy.
Nano-Liposomal Encapsulation (100–300 nm): Phospholipid bilayer spheres enclose sulforaphane molecules, significantly enhancing chemical stability and cell membrane permeability.
Standardized ≥ 4.0% Active Content: Precise HPLC testing ensures every production batch delivers a consistent active sulforaphane concentration of ≥ 4.0%.
Superior Bioavailability & Targeted Uptake: Overcomes the absorption limitations of conventional broccoli extracts, shielding active molecules through gastric transit for direct intestinal delivery.
Industrial-Grade Powder Flowability: 100% passes through an 80-mesh screen, yielding a fine, non-caking powder optimized for automated high-speed capsule filling and tableting equipment.
Purity & Global Regulatory Compliance: Heavy metals (Lead, Cadmium, Mercury, Arsenic) are controlled well within strict international limits with zero pathogenic contamination, fulfilling global dietary supplement standards.

Q1: What is the main advantage of Liposomal Sulforaphane over standard broccoli extracts?
A1: Unencapsulated sulforaphane is heat-sensitive and easily degraded by gastric acid, leading to low absorption. Liposomal encapsulation protects sulforaphane within 100–300 nm phospholipid spheres, allowing it to pass safely through stomach acid and significantly enhancing intestinal absorption and systemic bioavailability.
Q2: How well does this liposomal powder disperse in water? Is it suitable for liquid formulations?
A2: Our liposomal sulforaphane powder exhibits excellent water dispersibility. When stirred into water, it rapidly forms a homogenous nano-suspension without clumping or rapid settling, making it well-suited for ready-to-mix powders, liquid sachets, and functional drink mixes.
Q3: What processing parameters should be considered during manufacturing?
A3: To maintain the structural integrity of the liposomal spheres, we recommend avoiding prolonged exposure to high temperatures (keep below 40°C) and excessive shear forces during mixing or emulsification. Standard dry-blending procedures work perfectly for hard capsules and powder mixes.
Q4: What is the shelf life and stability under standard storage conditions?
A4: Stored in a cool, dry place (below 25°C) in original unopened packaging, the product maintains high stability over its 24-month shelf life. Liposomal encapsulation offers enhanced protection against oxidative degradation compared to free sulforaphane.
Q5: Can you provide free samples for lab testing and formulation evaluation?
A5: Yes! We provide complimentary samples and complete Technical Data Sheets (TDS) to qualified B2B clients, contract manufacturers, and formulation labs. Simply submit a request via email or our website to arrange sample delivery.
Q6: What customs clearance and compliance documentation do you provide for international orders?
A6: Every shipment includes a lot-specific Certificate of Analysis (COA), Safety Data Sheet (MSDS), Packing List, Commercial Invoice, Certificate of Origin (COO), and Non-GMO declaration to facilitate smooth customs clearance.
