NTC Technology: The FitLine Advantage

One of FitLine's key differentiators is Nutrient Transport Concept (NTC) technology. This patented technology is designed to:

1. Optimize absorption: nutrients are transported where they are needed, when they are needed
2. Greater bioavailability: Studies show superior absorption compared to standard formulations
3. Timed release: Nutrients are released gradually

Neither Herbalife nor Amway have equivalent proprietary nutrient absorption technology.

Anti-Doping Certification

This aspect is crucial for those who play sports:

• FitLine: present in the Cologne List, the most rigorous anti-doping certification in the world. Official partner of Olympic federations.
• Herbalife: sponsor CR7 (Cristiano Ronaldo), but the products are not certified anti-doping by the Cologne List
• Amway Nutrilite: not present in the Cologne List

• Stricter regulations on the quality of supplements
• Pharmaceutical standards in production
• Rigorous and frequent quality controls
• Transparency in the ingredient list
