What Is Sheep Kidney Peptide?
Sheep Kidney Peptide is a hydrolyzed animal protein ingredient made from fresh, healthy sheep kidney tissue.
The raw material comes from sheep raised in the Xilin Gol grassland area of Inner Mongolia. During production, protease enzymes break large kidney proteins into shorter peptides and amino acids. The peptide liquid is then separated, concentrated and dried into a fine powder.
This product differs from ordinary sheep kidney powder. Whole kidney powder contains mainly intact tissue proteins. The peptide grade has undergone controlled enzymatic hydrolysis and has defined peptide and molecular-weight specifications.
Other Names
Common product names include:
- Ovine Kidney Peptide Powder

- Hydrolyzed Sheep Kidney Protein
- Sheep Kidney Hydrolysate Powder
- Small-Molecule Sheep Kidney Peptides
- Ovine Kidney Oligopeptide Powder
- Sheep-Derived Kidney Peptides
- Enzymatically Hydrolyzed Lamb Kidney

The product has no single CAS number or molecular formula because it contains many peptide molecules rather than one purified compound.
Solubility and Peptide Size
The standard product is soluble in water at pH 5.4 to 6.0. Trace white peptide particles may remain after dispersion.
At least 85% of the tested peptide distribution falls below 500 Da. Enzymatic hydrolysis breaks intact proteins into smaller peptides before consumption. Protein hydrolysates can be digested and absorbed faster than the corresponding intact proteins, although the result depends on the protein source and formula.
This does not mean the peptides enter organs unchanged or directly repair kidney tissue.
pH and Heat Stability
The specification states stability from pH 4.0 to 9.0. It also states that the powder can withstand 100°C for 30 minutes and 121°C for 20 minutes under the tested conditions.
These values help with early formulation planning. Finished products still require testing for color, flavor, sediment and peptide stability.
Unicorns Biotechnology supplies bulk powder and provides OEM capsules, tablets, sachets and private-label formulas. Particle size, packaging and selected test limits can be customized.
Protein and Peptide Composition
Sheep Kidney Peptide Powder is standardized by its protein level, peptide content and molecular-weight distribution.
| Main Component | Specification | Role |
|---|---|---|
| Protein | ≥70.0%, dry basis | Main protein-derived material |
| Peptides | ≥65.0%, dry basis | Primary standardized fraction |
| Peptides below 500 Da | ≥85.0% | Small-molecule peptide profile |
| Moisture | ≤7.0% | Helps control caking and storage |
| Ash | ≤9.0% | Controls total mineral residue |
| Amino acids and minor solids | Remaining fraction | Natural result of hydrolysis |
The powder contains short peptides and free amino acids derived from ovine kidney proteins. The exact amino acid profile depends on the raw material, enzyme system and degree of hydrolysis.
Does It Contain Glutathione, Selenium or Other Kidney Nutrients?
Fresh sheep kidney naturally contains protein, minerals and other tissue compounds. However, hydrolysis, purification and drying can change their final levels.
The current specification does not quantify:
- Glutathione
- Selenium
- Iron
- Zinc
- Vitamin B12
- Hormones
- Growth factors
These compounds should not be listed as standardized actives without batch-specific test results.
Sheep Kidney Peptide Powder is also not a testosterone ingredient. It should not be marketed as hormone replacement or a treatment for reproductive disorders.

Sheep Kidney Peptide Powder vs Sheep Kidney Powder
Both ingredients use sheep kidney, but their processing and formulation properties differ.
| Feature | Sheep Kidney Peptide Powder | Sheep Kidney Powder |
|---|---|---|
| Raw material | Fresh sheep kidney | Fresh or frozen sheep kidney |
| Main process | Enzymatic hydrolysis and purification | Drying and milling |
| Protein form | Short peptides and amino acids | Mainly intact proteins |
| Peptide content | ≥65% | Usually not standardized |
| Molecular-weight control | ≥85% below 500 Da | Usually not tested |
| Water solubility | Soluble grade | Usually limited |
| Appearance | White to light yellow | Tan, brown or reddish-brown |
| Taste and odor | Characteristic peptide taste | Stronger organ taste |
| Best formats | Drinks, sachets, capsules and tablets | Capsules, tablets and organ blends |
| Product concept | Concentrated peptide ingredient | Whole-organ nutrition |
Choose Sheep Kidney Peptide Powder when solubility, peptide content and small molecular size matter.
Choose conventional sheep kidney powder when the product concept is based on whole-organ nutrition and minimal processing.
Sheep Kidney Peptides vs Bovine Kidney Peptides
Sheep and bovine kidney peptides use the same type of processing but come from different animal species.
| Feature | Sheep Kidney Peptides | Bovine Kidney Peptides |
|---|---|---|
| Animal source | Sheep or lamb | Cattle |
| Technical name | Ovine kidney hydrolysate | Bovine kidney hydrolysate |
| Product position | Sheep-based organ nutrition | Beef-based organ nutrition |
| Source preference | Suitable for ovine-focused formulas | Suitable for bovine-focused formulas |
| Religious requirements | Depends on source and certification | Depends on source and certification |
| Peptide quality | Defined by assay and size profile | Defined by assay and size profile |
Neither source is automatically better. Buyers should compare peptide content, molecular-weight distribution, traceability and certification.
Nutritional Benefits of Sheep Kidney Peptide Powder
The strongest benefits come from its measured composition and physical properties. Product-specific human clinical studies were not included in the supplied information.
Concentrated Peptide Nutrition
The powder contains at least 65% peptides and 70% protein on a dry basis. It provides a measured sheep kidney peptide fraction without relying only on whole dried tissue.
Small-Molecule Peptide Profile
At least 85% of the tested peptide distribution is below 500 Da. The proteins have already been broken into short fragments through enzyme digestion.
This supports a digestibility-focused position. It does not prove direct kidney targeting or tissue repair.
Water-Soluble Format
The powder can be used in formats that are difficult for ordinary organ powders. Examples include instant drinks, sachets, oral liquids and soluble nutrition blends.
Trace sediment may remain, so each finished formula needs a dispersion test.
Organ-Based Wellness Formulas
Sheep kidney has a long history of use in traditional food and organ-based nutrition. Traditional Chinese use links sheep kidney with vitality, physical strength and male wellness.
These are traditional-use concepts, not proven medical effects. The supplied research notes also state that proposed antioxidant, anti-fatigue, immune and reproductive effects need more human evidence.
Processing Flexibility
The stated pH range and heat tolerance allow the ingredient to be tested in several dry and liquid systems. Formulators should still confirm flavor, color and stability after processing.
Sheep Kidney Peptide Powder Manufacturing Process
Sheep Kidney Peptide Powder is made through controlled enzymatic hydrolysis. The process converts fresh ovine kidney proteins into a peptide-rich, water-soluble powder.
1. Sheep Kidney Selection
Fresh, healthy kidneys are collected from qualified sheep raised in the Xilin Gol grassland region. Each batch is checked for tissue identity, freshness and veterinary status.
2. Cleaning and Trimming
Blood residue, fat, connective tissue and unwanted material are removed. The kidneys are washed under controlled hygienic conditions.
3. Low-Temperature Homogenization
The cleaned tissue is minced and homogenized into a uniform slurry. Low-temperature handling helps protect the raw proteins.
4. Degreasing
Part of the natural fat is removed to improve filtration, flavor and powder stability.
5. Protease-Directed Hydrolysis
Selected protease enzymes break large kidney proteins into shorter peptides. Temperature, pH, enzyme dose and reaction time are closely controlled.
6. Enzyme Inactivation
Controlled heating stops the enzyme reaction after the target peptide profile is reached.
7. Centrifugation and Filtration
Insoluble tissue, coarse particles and remaining fat are removed. Membrane filtration may be used for tighter peptide-size control.
8. Concentration
The clarified peptide liquid is concentrated under controlled temperature conditions.
9. Spray Drying
The concentrate is spray-dried into a white to light-yellow, free-flowing powder.
10. Sieving and Testing
The finished powder is sieved and tested for protein, peptide content, molecular-weight distribution, moisture, ash and solubility.
11. Export Packaging
Approved batches are packed in food-grade inner liners and fiber drums. Custom bags, drums and private labels are available.
Process flow: Fresh sheep kidney → Cleaning → Homogenization → Degreasing → Enzymatic hydrolysis → Enzyme inactivation → Filtration → Concentration → Spray drying → Sieving → Testing → Packaging
