Feeling overwhelmed by digestive supplement trends? As a plant extract specialist, I constantly explore nature's hidden gems. Today, let's rediscover a centuries-old digestive ally now backed by modern science: Chicken Gizzard Lining Extract Powder (Endothelium Corneum Gigeriae Galli Extract). Often overlooked in the West, this traditional powerhouse offers unique benefits for gut health and beyond. Let's dive into why savvy formulators are turning to this unique ingredient.
What Exactly is Chicken Gizzard Lining Extract Powder?
The gizzard is a muscular part of a chicken's stomach designed to grind hard food (like grains and seeds) with the help of ingested grit. Its inner lining – a tough, golden-yellow membrane – is meticulously separated, dried, and pulverized into a fine powder.
Traditional Name: Ji Nei Jin (鸡内金) in Traditional Chinese Medicine (TCM), used for over 2,000 years.
Key Components:
Potent Proteolytic Enzymes (e.g., Pepsin-like enzymes): Crucial for protein breakdown[1].
Bioactive Keratin Peptides: Derived from the keratin-rich membrane structure[2].
Amino Acids (Glycine, Proline, Cysteine): Building blocks for gut repair and glutathione synthesis.
Trace Minerals (Zinc, Iron, Selenium): Support enzymatic functions and overall health.
Science-Backed Benefits: Why Your Formulations Need It
1. Enhances Protein Digestion & Nutrient Absorption
Mechanism: The extract naturally contains proteolytic enzymes that survive mild processing. These enzymes help break down dietary proteins into smaller peptides and amino acids in the stomach and upper intestine[1].
Benefit: Supports efficient digestion, reduces bloating/discomfort from protein-rich meals, and improves amino acid bioavailability. Ideal for sports nutrition, senior nutrition, or general digestive support blends.
Evidence: TCM clinical practice and modern pharmacological studies confirm its digestant properties[3].
2. Supports Gastric Mucosal Integrity & Comfort
Mechanism: Emerging research suggests bioactive peptides in the extract may help protect and strengthen the gastric mucosal lining[2]. Keratin-derived peptides exhibit mucosal protective effects.
Benefit: Promotes a healthy gut barrier, potentially reducing gastric discomfort associated with occasional irritation. Valuable for gut-soothing formulas.
3. Promotes Healthy Gut Motility
Mechanism: TCM pharmacology and animal studies indicate Ji Nei Jin helps normalize gastrointestinal peristalsis (muscular contractions)[3][4]. It may gently stimulate sluggish digestion without harsh laxative effects.
Benefit: Addresses occasional sluggish digestion, supports regularity, and reduces feelings of fullness.
4. Provides Bioavailable Keratin-Derived Peptides
Mechanism: The unique keratin structure in the gizzard lining is partially broken down during extraction, releasing soluble peptides rich in cysteine, glycine, and proline[2].
Benefit: These peptides serve as building blocks for the body's own collagen, glutathione (a master antioxidant), and gut repair processes.
5. Traditional TCM "Spleen-Stomach" Tonic
Mechanism: In TCM theory, Ji Nei Jin strengthens the Spleen-Stomach system, addressing patterns like "food stagnation" and "spleen qi deficiency" manifesting as poor appetite, indigestion, and fatigue[3][5].
Benefit: Offers a holistic, systems-biology approach to digestive wellness valued in integrative health products.
Applications: Where Chicken Gizzard Extract Powder Shines
- Human Dietary Supplements:
Digestive Enzymes Blends (combined with amylase, lipase, bromelain)
Gut Health & Microbiome Support Formulas
TCM / Herbal Digestive Tonics
Protein Powder Additive (to enhance digestibility)
- Pet Nutrition (Especially Dogs & Cats):
High-Protein Diet Digestive Aids
Sensitive Stomach Support
Appetite Stimulation
- Functional Foods (Requires Soluble Forms):
Digestive Wellness Shots or Tonics (traditional preparation)
Why Source Chicken Gizzard Lining Extract Powder?
- Natural & Traditional: Meets demand for clean-label, traditionally used ingredients.
- Synergistic: Complements probiotics, prebiotics, and other digestive enzymes.
- Unique Mechanism: Offers benefits distinct from standard microbial-derived enzymes (like pepsin support and mucosal peptides).
- Growing Niche Appeal: TCM efficacy and "nose-to-tail" sustainability resonate with informed consumers.
Key Considerations for B2B Buyers
- Quality & Purity: Ensure suppliers provide COA (Certificate of Analysis) confirming:
Low Heavy Metals (Pb, As, Cd, Hg)
Low Microbial Count (TPC, Yeast/Mold, Salmonella, E.coli)
Identification (HPLC/TLC fingerprint vs. reference standard)
- Processing: Low-temperature drying preserves enzymatic activity.
- Solubility: Native powder has limited water solubility. Soluble extracts (using hydrolysis) are available for liquid formulations but may alter the profile.
- Allergen Statement: Naturally gluten-free, dairy-free. State poultry origin clearly.
- Sustainability: Source from reputable suppliers adhering to animal welfare and by-product utilization standards.
Unlock the Digestive Wisdom of Nature
Chicken Gizzard Lining Extract Powder (Ji Nei Jin) is far more than a historical curiosity. Modern science is validating its traditional use as a potent digestive aid, offering unique enzymatic and peptide benefits for gut health and comfort. As formulators seek differentiated, effective, and natural ingredients, this traditional extract deserves serious consideration.
