Quality

Product formulators and contract manufacturers who are interested in the use of fulvic acid as an ingredient in their products should insist on obtaining information from the supplier or manufacturer regarding their testing method and outcomes. Additionally, they should seek certification to ensure the reliability and accuracy of the testing process.

We pride ourselves on the quality and uniqueness of our fulvic acid and can provide necessary reports to certify our statements.

HISTORY OF TESTING METHODS OVER TIME: 

  • COLORIMETRIC/SPECTROPHOTOMETRIC  1940s
  • SIZE EXCLUSION CHROMATOGRAPHY METHOD  1960s
  • CLASSICAL METHOD 1970s
  • LARRY G. BUTLER METHOD (LGB) 1980s
  • CDFA (aka California method)
  • SWIFT METHOD 1990s
  • V&B (aka Verploegh and Brandvold method)

Mineral Biosciences uses all 3 of these tests methods:

Verploegh and Brandvold method (V&B)

  • Quantifies both humic and fulvic acids

Lamar Method/AOAC/IHSS

  • The insoluble material is removed from the alkaline dissolved HA and FA material to quantify fulvic acid only.

ISO Method

  • The ISO method identifies hydrophobic fulvic acids (HFA) as separate from humic acids (HA) derived from the raw source material.

*The LAMAR and ISO method are the most similar. Despite the differences, such as the incubation time and temperature, it is likely that the two methods would give very similar results.
