GINSENG REPORT

Labdoor analyzed 6 of the best-selling ginseng supplements in the United States for ginsenoside content, pesticide residues, and heavy metal (arsenic, cadmium, and lead) contamination.

Products in this batch analysis measured an average of 25.1 mg of ginsenosides per serving, ranging from 15.5 mg to 31.8 mg. Lab-tested ginsenoside content ranged from -77.4% to +136.5% as compared to the product’s label claims.

Measured ginsenoside content deviated from label claims by an average of 48.2%. None of these products that claimed ginsenoside content on their labels recorded ginsenoside levels within 10% of their label claims.

Every product in this analysis passed all 3 heavy metal screenings (arsenic, lead and cadmium), indicating that products measured less than 2 PPM of each heavy metal. All products also passed screenings for 18 known pesticide residues.

Analytical Chemistry Methods: HPLC (High Performance Liquid Chromatography) to quantify ginsenoside content; ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometry) to quantify heavy metal load; GC-MS (Gas Chromatography - Mass Spectrometry) to quantify pesticide residue levels.
