Colostrum Capsules for Gut Health & Immune Support High IgG (25%)
Product Overview:
Bovine colostrum is a special milk produced by mammals (mainly cattle) in the first 24-72 hours after giving birth. This "liquid gold" is rich in immune factors, growth factors, and nutrients, and is a natural source for newborns to establish their first line of defense. Bovine colostrum capsules are a convenient, standardized form of supplementation that preserves the bioactive components of this precious substance through low-temperature processing.

Key Bioactivity Parameters of Bovine Colostrum Capsules:
Immunoglobulin Concentration: More Than Just IgG
- The differentiation of high-end European and American bovine colostrum capsules begins with their immunoglobulin profile. Premium products not only provide high concentrations of IgG (immunoglobulin G), but also maintain the complete natural proportions of IgA, IgM, and IgE. Studies have shown that a complete immunoglobulin matrix provides broader immune support than a single high concentration of IgG.

Our Bovine Colostrum Capsules: Key Bioactivity Indicators and Quality Control Standards
As a capsule manufacturer, we focus not only on the source of the colostrum powder, but also on the retention rate of immunoglobulin bioactivity throughout the entire production process.
- Immunoglobulin Profile (Not Just IgG): We test and ensure that the ratio of IgG, IgA, and IgM in the finished capsules closely approximates that of natural colostrum (typically IgG accounts for 75-80%, and IgA and IgM account for 20-25%), rather than simply increasing the content of IgG alone. Testing Method: ELISA method, ensuring that the detection is of bioactive proteins, not denatured protein fragments.
- Activity Retention Rate: Our processing technology uses low-temperature freeze-drying (not spray drying), with the freeze-drying temperature controlled below -40°C. The filling process is completed at room temperature (<25°C) and in a low humidity environment (RH <35%), ensuring that the immunoglobulin bioactivity retention rate is >90%.
- Lactoferrin and Growth Factors: We test the levels of naturally occurring lactoferrin, EGF, and IGF-1 in each batch to ensure the lactoferrin to immunoglobulin ratio is maintained between 1:15 and 1:25. Studies suggest this ratio is most beneficial for gut health and immune support.
OEM Customization Flexibility:
- Immunoglobulin Concentration: Customizable IgG content of 10%, 20%, 30%, 40%, etc.
- Capsule Type: Gelatin capsules (standard) or enteric-coated capsules (protecting immunoglobulins from stomach acid to the intestines).
- Combination Options: Probiotics, prebiotics, zinc, and other synergistic ingredients can be added.
- Minimum Order Quantity: 50 bottles (sample batch), 100,000 capsules (bulk orders).
Frequently Asked Questions
Q1: What is the fundamental difference between bovine colostrum capsules and regular protein powder?
- A: The core value of bovine colostrum capsules lies in their bioactive components, especially immunoglobulins, growth factors, and antimicrobial peptides, which are almost absent in regular whey protein. This is the essential difference between functional foods and basic nutritional supplements.
Q2: How to verify the quality of bovine colostrum capsules?
- A: Request the supplier to provide a Certificate of Analysis (COA) from a third-party laboratory, paying particular attention to: 1) Immunoglobulin activity (not just content); 2) Microbiological safety indicators; 3) Heavy metal testing report; 4) Processing temperature records.
Q3: What are the differences in dosage between athletes and the general healthy population?
- A: According to the American College of Sports Medicine, higher doses (500-1000 mg immunoglobulin daily) are typically required for exercise recovery, while lower doses (200-500 mg daily) are generally needed for general immune support. Specific recommendations should be followed according to the product label and professional advice.
Q4: Are bovine colostrum capsules suitable for people with lactose intolerance?
- A: High-quality bovine colostrum capsules typically contain less than 1% lactose, which is tolerable for most people with lactose intolerance. However, those with extreme sensitivity should choose products that have undergone lactose removal treatment and start with a small dose.
