FSSC 22000-certified facility with Kosher, Halal, and SC-certified programs
Full raw-material traceability with a supplier audit program
Product Benefits
Broccoli seed extract 13% glucoraphanin has been verified by multiple clinical studies and industry experiments, with stable and efficient physiological activity, and its core advantages are far superior to ordinary broccoli extract products :
1. Powerful Cellular Detoxification & Antioxidation
Glucoraphanin is a natural precursor of sulforaphane. After entering the human body, it can be efficiently converted into active sulforaphane with the help of myrosinase or intestinal flora. It activates the body's Nrf2 antioxidant pathway, enhances the activity of cellular detoxification enzymes, removes free radicals and metabolic waste in the body, and resists oxidative damage caused by aging and external environmental stimulation . Compared with direct sulforaphane products, glucoraphanin has higher stability, will not lose activity during processing and storage, and has longer-lasting efficacy.
2. Support Healthy Aging & Metabolic Balance
Long-term supplementation of standardized 13% glucoraphanin helps regulate human metabolic levels, improve sub-health problems caused by metabolic disorders, and delay cellular aging. It is an efficient raw material for developing anti-aging and daily wellness functional products, suitable for long-term daily health care formula matching .
3. Improve Body Immunity & Anti-Inflammatory
As a natural active sulfur-containing glycoside compound, glucoraphanin has significant anti-inflammatory activity, can reduce chronic inflammatory reactions in the body, enhance the body's immune defense ability, and help maintain the stability of the immune system. It has broad application prospects in immune health functional foods.
Product Application
Cellular Detoxification Supplements
Cellular detoxification is a growing category as consumers seek to support their body's natural ability to process environmental toxins, pollutants, and metabolic byproducts through nutritional intervention.
Glucoraphanin 13% supports Phase II detoxification by activating the Nrf2 pathway, which upregulates glutathione S-transferase and other detoxification enzymes. Typical formulas combine it with NAC, milk thistle, and alpha-lipoic acid for comprehensive liver and cellular detox support.
HPLC-verified glucoraphanin content and documented Nrf2 mechanism support credible detox positioning and differentiate from generic antioxidant blends.
Antioxidant & Anti-Aging Formulations
The antioxidant and anti-aging supplement market continues to expand, with consumers increasingly seeking ingredients that support cellular protection at the genetic and enzymatic level rather than simple free-radical scavenging.
Glucoraphanin's role in activating the Nrf2 pathway provides an upstream antioxidant mechanism that enhances the body's own defense systems, complementing direct antioxidants like vitamin C, E, and CoQ10 in capsule or tablet formulations.
The Nrf2 activation story and HPLC-verified content support premium positioning in the anti-aging category, where consumers expect evidence-based ingredient claims.
Immune & General Wellness Products
Immune health remains a top consumer priority, with growing interest in ingredients that support immune function through cellular health and detoxification pathways rather than direct immune stimulation.
Glucoraphanin 13% contributes to immune wellness formulations by supporting cellular detoxification and antioxidant capacity, typically combined with vitamin D, zinc, elderberry, and echinacea in comprehensive immune support products.
case study
Confidential — European Wellness Supplement Brand
A European wellness supplement brand developing a new cellular detox line needed a glucoraphanin supplier able to deliver consistent quality, HPLC-verified content, and support for Nrf2 pathway positioning. After evaluating multiple broccoli seed extract manufacturers, they selected our glucoraphanin 13% grade based on batch consistency, competitive pricing, and comprehensive documentation.
Qualified as an approved supplier within four weeks
Scaled from a 50 kg trial to a quarterly bulk program of approximately [300] kg
Glucoraphanin content remained within specification across the first six lots
Zero batch rejections and on-time delivery across the first year
Result: the cellular detox capsule line launched successfully with glucoraphanin as a key differentiator, and the brand expanded to include a higher-strength formula the following year.
FAQ
Q1: What is the difference between 13% Glucoraphanin (GR-13) and Sulforaphane (SFN) extract?
GR-13 is standardized with stable glucoraphanin content, which is the precursor of sulforaphane. It has ultra-high dry powder stability, not easy to decompose during processing and storage, and is suitable for long-term storage and various formula processing. SFN series products are activated finished sulforaphane with higher immediate activity but poorer stability. GR-13 has lower formulation cost and wider applicability, which is the mainstream choice of stable formula raw materials in the industry .
Q2: Is your 13% glucoraphanin product natural and safe?
Absolutely safe. Our products are extracted from pure natural non-GMO broccoli seeds with food-grade pure water, no organic solvent residue, no artificial pigments, preservatives and additives. All heavy metal and microbial indicators pass third-party testing, compliant with global food and health product safety standards, and can be safely used in dietary supplements and functional foods .
Q3: What are the storage and shelf life requirements of the product?
The product should be stored in a sealed, dry, cool and dark environment, avoiding high temperature and humidity. The shelf life is 24 months under standard storage conditions. After opening, it is recommended to use it up within 3 months to avoid moisture affecting product stability.
Q4: What dosage forms can 13% glucoraphanin be used for?
The product has good water solubility and powder fluidity, compatible with almost all health product dosage forms, including capsules, tablets, powder sachets, solid beverages, meal replacement powder, compound functional formulas, etc., with low processing difficulty and strong formula adaptability .
Q5: Can you provide customized services and complete qualification documents?
Yes. We support customized content, fineness and packaging of glucoraphanin, and can provide complete documents such as COA test report, SDS safety data sheet, non-GMO certificate, food production qualification and third-party test reports to meet customer's global market access needs .
Q6: What is the MOQ and delivery time?
The minimum order quantity is 25 kg, with sufficient spot inventory. Small orders can be delivered within 3-5 working days, and bulk orders can be delivered stably according to customer requirements. We support multiple international logistics methods to ensure fast and safe delivery of goods .
Q7: Does glucoraphanin need myrosinase to exert efficacy?
Glucoraphanin can be naturally converted into active sulforaphane through human intestinal flora. If matched with natural myrosinase sources such as mustard seed and horseradish powder, the conversion rate and bioavailability can be further improved, and the product efficacy is more stable .
