Panax ginseng and American ginseng belong to the same genus and are both sold as ginsenoside-standardized extracts, which makes them easy to confuse on a quotation. But their ginsenoside profiles point in different directions, and traditional and modern use treats them as distinct actives. This guide explains the chemistry, the traditional framing and how to write a specification for each. Core Nutrix supplies Panax ginseng extract standardized to ginsenosides 5-80% by HPLC (CAS 90045-38-8) and American ginseng extract standardized to ginsenosides 80% by HPLC (CAS 41753-43-9 for the Rb1 marker).
Same Genus, Different Profiles
- Panax ginseng (Panax ginseng C.A. Meyer, Asian or Korean ginseng) is the classic “energy” adaptogen, with an Rg1-dominant ginsenoside profile.
- American ginseng (Panax quinquefolius) has an Rb1-dominant profile and is traditionally described as the cooling, calming counterpart.
- Both are sold by total ginsenosides, but the Rg1/Rb1 balance – not just the total – determines the effect profile.
The Rg1/Rb1 Ratio Is the Real Specification
Ginsenosides are a family of dozens of compounds, but two markers drive practical differences. Rg1 is associated with stimulation, alertness and physical performance; Rb1 is associated with calming, restorative and metabolic effects. Asian ginseng runs Rg1-dominant, while American ginseng runs Rb1-dominant, which is why two powders with the same “80% ginsenosides” claim can behave very differently in the body. When you compare quotations, ask for the individual ginsenoside breakdown – Rg1, Rb1 and Re at minimum – rather than the total alone.
Traditional Use and Modern Positioning
- Panax ginseng: traditionally used for vitality and stamina; today positioned in energy, sports performance, immune and cognitive formulas.
- American ginseng: traditionally used for balanced, cooling support; today positioned in stress, metabolic, fatigue and immune products where a non-stimulating profile is preferred.
- Dose reference: typical finished products use 100-200 mg per day of standardized extract, with the exact amount set by your ginsenoside target.
How to Specify Each
- Panax ginseng: we supply ginsenosides 5-80% by HPLC, CAS 90045-38-8, as a light yellow-brown fine powder. Choose the percentage from your dose target – an 80% grade lets a single 250 mg capsule carry a strong daily dose.
- American ginseng: we supply a premium 80% ginsenosides grade by HPLC, with CAS 41753-43-9 for the Rb1 marker, also a light yellow-brown fine powder.
- Both: request the ginsenoside profile (Rg1, Rb1, Re), heavy metals, pesticides and microbiology on the COA, and confirm the plant part and origin.
Format and Blend Considerations
- Taste: ginseng extracts are bitter and earthy; capsules and tablets mask best, while powders and drinks need flavor systems.
- Handling: both are fine powders that blend and flow well in standard capsule and premix operations; slight hygroscopicity calls for sealed storage.
- Blends: combining the two in one formula is common when the claim is “day and night” or balanced adaptogenic support; the ratio then becomes the marketing story.
Sourcing, Origin and the COA Checklist
Origin drives both chemistry and price. Asian ginseng is grown mainly in Jilin, China and Korea, with roots aged four to six years commanding premium prices. American ginseng traditionally comes from North America, and significant Chinese-grown supply now exists as well; its Rb1-dominant profile is what makes it the calming counterpart.
- Panax ginseng: standardized to ginsenosides 5-80% by HPLC, CAS 90045-38-8; higher percentages suit single-capsule daily doses.
- American ginseng: standardized to ginsenosides 80% by HPLC, with CAS 41753-43-9 for the Rb1 marker.
- Profile, not just total: request Rg1, Rb1 and Re individually – the ratio is what separates the two ginsengs and what your label should reflect.
- Contaminant panel: root crops concentrate soil-borne residues, so heavy metals, pesticides and microbiology should be on every COA, and the extract color should be consistent between batches.
Both extracts ship as light yellow-brown fine powders in 25 kg drums with 24 months shelf life in sealed, cool, dry storage. If the product claims “energy” or “calm”, the ginsenoside profile on the COA – not the word “ginseng” alone – is what proves the positioning.
Frequently Asked Questions (FAQ)
Which ginseng is stronger?
They are not directly comparable. Asian ginseng is Rg1-dominant and stimulating; American ginseng is Rb1-dominant and calming. Choose by the effect profile your product promises.
What does 80% ginsenosides mean?
Each gram of extract contains 800 mg of total ginsenosides measured by HPLC. A COA that also lists Rg1, Rb1 and Re individually tells you the balance of the profile.
Can I blend the two ginsengs?
Yes. Blends are common in balanced adaptogen formulas. Specify the ratio of the two extracts and the ginsenoside contribution of each on the label.
What are the CAS numbers?
Panax ginseng extract uses CAS 90045-38-8; the American ginseng Rb1 marker uses CAS 41753-43-9. Both are printed on our specification sheets and COAs.
What documentation ships with each batch?
Every batch ships with a COA and MSDS, with the HPLC method, ginsenoside breakdown and contaminant panel stated. Third-party testing is available on request.
What is the MOQ for ginseng extracts?
Samples start at 0.5-1 kg and bulk ships in 25 kg drums with 24 months shelf life in sealed, cool, dry storage.
Which ginseng should I choose for an energy product?
Asian ginseng’s Rg1-dominant profile fits stimulation, stamina and performance claims; American ginseng suits products that promise balanced, non-jittery support, and many daytime formulas blend the two profiles deliberately.
How is the ginsenoside content verified?
By HPLC against ginsenoside reference standards, with the method and the Rg1/Rb1/Re breakdown printed on the COA. Independent third-party testing is available on request.
What is the typical serving size of a standardized extract?
Most finished products use 100-200 mg of standardized extract per day. Work backwards from your ginsenoside target – an 80% grade delivers 80 mg of ginsenosides per 100 mg of powder.
Do you supply both ginsengs for a blended formula?
Yes. We supply both extracts and can premix them to your ratio under our OEM service, with the blend ratio documented on the specification sheet.
