1. What Is 4Life Transfer Factor?
Unlike conventional immune supplements (such as high-dose Vitamin C or Elderberry) that work primarily by stimulating immune activity, Transfer Factors are immune messenger molecules. Extracted from bovine colostrum and chicken egg yolk via patented ultrafiltration processes, these micro-peptides perform three essential functions:
The 3 Essential Functions of Transfer Factor:
- Educate: Teaches immune cells to quickly identify new potential pathogens.
- Recognize: Supports Natural Killer (NK) cell responsiveness when the body faces physiological stress.
- Remember: Maintains an immunological memory bank so future responses are faster and more efficient.
2. US Manufacturing Standards & FDA Compliance
Quality assurance is critical when choosing health supplements in North America:
- cGMP Certified Facilities: 4Life products are manufactured in 4Life's state-of-the-art facilities in Utah, operating under strict FDA Current Good Manufacturing Practices (cGMP).
- Independent Quality Labs: Every batch undergoes over 20 grand-scale analytical tests for potency, heavy metals, microbial safety, and active ingredient verification.
