As someone who has worked in the plant extract industry for years, specializing in garlic extract production and B2B bulk supply, I know exactly what B2B buyers care about most when sourcing high-purity garlic extract: clear specifications, reliable industry standards, transparent stock grades, and practical purchasing tips. Every day, I receive inquiries from supplement factories, raw material wholesalers, and brand owners-most of them are confused about how to choose the right high-purity garlic extract, avoid procurement risks, and get the best value for bulk orders.
Today, I'll break down everything you need to know as a B2B buyer, from mainstream specifications and industry standards to factory stock grades and key purchasing precautions. My goal is to help you make informed decisions, streamline your procurement process, and confidently submit RFQ (Request for Quotation) for garlic extract raw materials. Whether you're a seasoned procurement manager or a new buyer in the health supplement industry, this guide is designed to be practical, easy to understand, and tailored to your bulk purchasing needs.
First, let's clarify what "high-purity garlic extract" means in the industry. Generally, high-purity garlic extract refers to products with a purity of 95% or higher, with standardized active ingredient content (mainly allicin or S-Allyl Cysteine, SAC) and minimal impurities. Unlike ordinary garlic extract, high-purity products are more suitable for high-end supplement formulations, pharmaceutical raw materials, and bulk customization-scenarios where quality and consistency are non-negotiable.
Mainstream Specifications of High-Purity Garlic Extract
As a B2B buyer, understanding specifications is the first step to accurate procurement. The core specifications of high-purity garlic extract are determined by active ingredients, purity, form, and solubility-these directly affect your formula compatibility, product efficacy, and purchasing cost.
Active Ingredient Specifications (Most Critical)
The two most common active ingredients for high-purity garlic extract are allicin and SAC, and their content is the key indicator of product quality:
- Allicin-standardized high-purity garlic extract: The mainstream specifications are 1.0%, 2.0%, 3.0%, and 5.0%. This type is widely used in antibacterial, anti-inflammatory, and lipid-regulating supplements. For bulk buyers, 1.0%-2.0% is the most cost-effective choice for mass production, while 3.0%-5.0% is suitable for high-end, targeted formulations.
- SAC-standardized high-purity garlic extract: Main specifications are 0.5%, 1.0%, and 2.0%. This is mainly derived from black garlic fermentation, with better absorption and milder properties, suitable for cardiovascular care and anti-aging products.
Purity & Form Specifications
- Purity: The standard high-purity level is 95%, 98%, and 99%. 95% purity is sufficient for most supplement formulations, while 98%-99% is used for pharmaceutical raw materials and high-end custom projects.
- Form: The two mainstream forms are powder and liquid. Powder (80-100 mesh) is easy to store, transport, and mix into tablets, capsules, or solid drinks-this is the most popular choice for bulk B2B buyers. Liquid extract is suitable for liquid supplements, oral solutions, and custom formulations, but requires special storage conditions (low temperature, sealed).
Solubility Specifications
High-purity garlic extract is divided into water-soluble and fat-soluble types:
- Water-soluble: Suitable for water-based formulations (e.g., functional drinks, oral sprays) and is easier to digest, making it ideal for sensitive stomach crowds.
- Fat-soluble: Suitable for oil-based formulations (e.g., soft capsules, lipid-soluble supplements) and has better absorption in the digestive system for fat-related health benefits.
Industry Standards for High-Purity Garlic Extract
For B2B buyers, verifying that the product meets industry standards is crucial to avoid inferior goods. Here are the most authoritative standards you need to know:
- International Standards: The main standards are USP (United States Pharmacopeia), EP (European Pharmacopoeia), and FCC (Food Chemicals Codex). These standards specify the minimum active ingredient content, impurity limits, and testing methods for high-purity garlic extract. For example, USP requires that allicin content in high-purity garlic extract must be within ±10% of the labeled value, and heavy metal content (lead, arsenic) must be less than 2ppm.
- Domestic Standards (China): GB/T 22254-2018 (Garlic Extract) and GB 1886.303-2021 (Food Additive Garlic Extract) specify the quality requirements for garlic extract in food and supplement industries, including purity, active ingredients, and safety indicators.
When sourcing, always ask the supplier to provide a certificate of analysis (COA) that complies with these standards-this is your best guarantee of product quality.
Factory Stock Grades of High-Purity Garlic Extract
Most garlic extract factories classify their high-purity products into three grades to meet different B2B purchasing needs. Understanding these grades will help you match your procurement budget and product positioning:
Grade A (High-End Custom Grade)
- Purity: 98%-99%
- Active Ingredient Content: 3.0%-5.0% (allicin) or 1.0%-2.0% (SAC)
- Features: Strict quality control, batch-to-batch consistency, custom specifications available (e.g., specific solubility, particle size)
- Applicable: High-end supplement brands, pharmaceutical raw materials, custom formulation projects
- MOQ (Minimum Order Quantity): Usually 500kg or more; suitable for large-scale bulk buyers
Grade B (Regular Bulk Grade)
- Purity: 95%
- Active Ingredient Content: 1.0%-2.0% (allicin) or 0.5%-1.0% (SAC)
- Features: Stable quality, mature production process, cost-effective, large stock available
- Applicable: Mass-market supplement factories, raw material wholesalers, OEM/ODM projects
- MOQ: 100kg-500kg; the most popular choice for most B2B buyers
Grade C (Cost-Effective Grade)
- Purity: 95%
- Active Ingredient Content: 0.5%-1.0% (allicin) or 0.3%-0.5% (SAC)
- Features: Competitive price, basic quality guarantee, suitable for entry-level formulations
- Applicable: Small-scale supplement factories, trial orders, cost-sensitive projects
- MOQ: 50kg-100kg; ideal for buyers who want to test the product before large-scale procurement
Bulk Purchase Precautions for B2B Buyers
After understanding specifications, standards, and grades, here are the key precautions to keep in mind when making bulk purchases-these are the lessons I've learned from years of working with B2B buyers:
1. Verify Supplier Qualifications
Always check the supplier's factory qualifications: GMP certification (Good Manufacturing Practice), ISO 9001 quality management system, and export licenses (if you need international shipping). Avoid suppliers who cannot provide these certifications, as they may offer inferior or non-compliant bulk garlic extract products.
2. Request Batch Testing Reports (COA)
Before placing a bulk order, ask for a COA for the specific batch of garlic extract. Focus on active ingredient content, purity, heavy metal limits, and microbial indicators-ensure they meet the industry standards you require. For critical projects, you can also arrange third-party testing to verify the product quality.
3. Confirm Supply Capacity & Delivery Time
For bulk orders, supply capacity is key. Ask the supplier about their current stock, monthly production capacity, and delivery time. Most factories can deliver Grade B high-purity garlic extract within 7-10 days, while Grade A custom products may take 2-4 weeks. Clarify the delivery terms (FOB, CIF) and logistics costs in advance to avoid unexpected expenses.
4. Negotiate Quality Assurance & After-Sales Policy
Discuss the quality assurance policy with the supplier: What if the product does not meet the agreed specifications? Will they provide a replacement or refund? For bulk orders, it's also important to clarify the shelf life (usually 2 years for powder extract, 1 year for liquid extract) and storage conditions to ensure product stability.
5. Clarify Customization Capabilities (If Needed)
If you need custom specifications (e.g., specific active ingredient content, solubility, or packaging), confirm with the supplier whether they can meet your requirements. Reputable high-purity garlic extract suppliers will have professional R&D teams to support custom formulation and processing.
How to Submit an Effective RFQ for High-Purity Garlic Extract
