Perhaps you have seen or purchased a supplement that promised to rise to the quality of standardized herbal supplements. What did that mean? Why should such a supplement be rated as an above-average supplement?

In each of the standardized herbal supplements, the amount of the main ingredient has been standardized with reference to an assayed chemical. In other words, the chemistry of the primary herbal ingredient has been compared to the chemistry of a pure chemical. That comparison has been completed by using various assay methods.

For some standardized herbal supplements, the comparison between the chemistry of the herbal mixture and the chemistry of the pure reference chemical is completed by using a Java burn fat burner spectrophotometer. The spectrophotometer measures the wave length of light in the spectrum of both assayed chemicals.

For a second group of standardized herbal supplements, the comparison between the chemistry of the herbal mixture and the chemistry of the pure reference chemical requires use of high pressure liquid chromatography (HPLC). Chromatography is a process whereby the various chemical components of a substance are separated according to how quickly they travel in an electrically-charged field.

For yet a third group of standardized herbal supplements, the comparison of the herbal and reference chemicals requires use of titrimetry. That is an assay method in which the chemist measures the amount of a reagent that combines with a known analyte. That measurement could take place in one of three fashions.

For most standardized herbal supplements, the type of titrimenty most often used for assay purposes is gravimetry. In gravimetry the reagent of interest in an assay is measured according to its weight. A standardized herbal supplement would therefore have the same weight as a previously-analyzed, herb extract and solvent duo.
