How to Source Ginseng Extract in 2026?
Set a verified ginsenoside target before requesting samples. A practical starting point is ≥10% total ginsenosides, measured on a defined dry basis. This number is a specification, not proof of quality. Ginseng composition varies with species, plant age, harvest season, and extraction conditions. I would require the botanical identity, plant part, extraction ratio, solvent, and moisture level. Small details matter.
Ask suppliers for batch-specific HPLC or UPLC results, not a generic product sheet. The report should identify key markers, including Rg1, Rb1, Rg3, and Re, where relevant. It should explain how “total” was calculated. USP quality guidance emphasizes identity, purity, and characteristic constituent testing for botanical materials. Independent laboratory confirmation remains valuable. It may expose an uncomfortable gap between a claimed 10% result and the actual lot.
Market pressure also supports tighter verification. The 2024 HerbalGram market report recorded US herbal supplement sales of approximately $12.6 billion in 2023. The Global Wellness Institute valued the worldwide wellness economy at $6.3 trillion in 2023. These figures indicate strong demand, but demand can reward vague claims. A supplier should provide a certificate of analysis, heavy-metal results, microbial limits, pesticide screening, and stability data. I would also retain a sealed reference sample. One weakness remains: a single test cannot describe every future batch. Oversight must continue.
