Herbalife has developed a proprietary method for identifying and measuring aloins—chemical compounds such as aloin A, aloin B, and aloe-emodin—in aloe vera. This method has been officially certified by AOAC International, a globally recognised authority in analytical science.

Why This Matters

  • Safety standard compliance: Regulatory bodies require companies to monitor the levels of anthraquinones (such as aloin) in ingestible aloe vera products to ensure consumer safety.
  • Industry-leading validation: Herbalife’s testing method is the first to be approved by AOAC International, setting a new benchmark for botanical and dietary supplement testing.

Method Details

  1. Rigorous multi-lab study
    • Eight independent laboratories from around the world participated.
    • Each tested six aloe vera samples, including both raw materials and finished products.
    • The method uses High-Performance Liquid Chromatography (HPLC) to precisely measure aloin compounds and aloe-emodin.
  2. Global consistency
    • The method met strict AOAC criteria for precision, reliability, and overall performance.
    • It has been certified under the official designation AOAC 2016.09 Final Action Method.

High-Level Quality Assurance

  • Herbalife applies this testing method to every batch of its aloe-based products sold in over 90 countries, ensuring both safety and preservation of natural benefits.
  • The company uses advanced proton nuclear magnetic resonance (NMR) spectrometry to verify molecular identity and purity—going far beyond standard supplier tests.
  • Herbalife’s quality system includes in-house ISO 17025-accredited laboratories, Good Manufacturing Practices (GMP), and certification to NSF standards.
