Some people only know of ginseng as an ingredient in energy drinks and unusual candy bars, but the plant — actually the root of plants in the Panax genus — has some compelling evidence supporting its use for improving mood, immunity, and cognition.
When considering one of these supplements, it’s important to look at the dosage, the amount of the active ingredient (ginsenosides), the price, and other factors. We pored through the industry’s best supplements to bring this list of the best of the best.
NatureBell Panax Ginseng
This is one of the best value and one of the strongest ginseng products, delivering 1,500 milligrams of organic, non-GMO Panax ginseng that’s standardized to include at least 15 percent ginsenosides. That’s remarkably potent, and the quality is backed up by third party testing and certification from the United States Pharmacopeia.
- This is a very inexpensive ginseng supplement, particularly given the ginseng is organic.
- The product is third party tested for purity and potency.
- NatureBell’s ginseng is stronger than most, with a minimum of 15 percent ginsenosides (most set their threshold at 5 percent or less).
- Some find the capsules a little too large and hard to swallow.
- These capsules are made from kosher gelatin, so they’re not vegetarian friendly.
- While it’s labeled as organic ginseng, this hasn’t been certified organic by the USDA.

NutraChamps has a terrific balance of quality, value, and transparency. Providing a gram of Panax ginseng with a minimum of 5 percent ginsenosides, NutraChamps is well dosed, well priced, non-GMO, vegan friendly, made in the United States, has no preservatives, and it’s third party tested to ensure label accuracy and purity.

Some prefer liquid ginseng as it may help with absorption, and ILHWA’s ginseng is the best pick. Fermented to contain at least 12 percent ginsenosides, it’s non-GMO, kosher certified, and uses GS15-4™ ginseng, which uses enzyme fermentation that may produce a more bioavailable form of the root.

How We Picked the Best
A lot of ginseng supplements provide under 100 milligrams of the root, while most research suggests a dosage of at least 200 to 400 milligrams to produce favorable effects. For this reason we favored products with higher doses that were split over more than one pill, so consumers can take lower doses if they feel it’s necessary.
We heavily favored supplements that include that percentage of ginsenosides, the active compounds in ginseng. Studies that have found favorable results from ginseng supplements that contained at least 3 percent ginsenosides.
After looking at many different products, we determined that 15 to 50 cents per gram of ginseng is an acceptable range for cost. More expensive options were considered unnecessary.
This wasn’t an especially important factor, but many prefer their supplements to be free from fillers (such as rice flour) or to be vegetarian friendly, which we took into account when landing on our list.
Third Party Testing
An important aspect in supplements is third party testing, which means a company employs an outside organization to ensure the purity and accuracy of the product’s contents. This can bring peace of mind to folks who are wary of the fact that supplements aren’t regulated by the FDA.
What Are the Benefits of Ginseng?
Some research has suggested that ginseng may exert beneficial effects in the following areas.
This is the principle effect — it’s front and center on practically every supplement’s list of benefits. Increases in cognition, mood, memory performance, and sociability may occur due to ginseng’s anti-fatigue effects.(1)(2)(3)
Some research has found ginseng supplementation to decrease fasting blood glucose among people with diabetes.(4) The same effect isn’t quite as reliably seen in people who don’t have diabetes.
Blood Flow/Erectile Dysfunction
Increases in blood flow have been seen in some studies, which could be why limited research has found ginseng to improve erectile dysfunction.(5)(6)(7)(8)
Some research has found markers of oxidation to be reduced and the induction of antioxidant enzymes to be increased when supplementing ginseng.(9)(10)
Ginseng may increase blood flow, decrease blood sugar, “speed up” the nervous system, and/or act like a stimulant for some people, which means there can be some potential problems with drug interaction. For example,
- Insulin decreases blood sugar; since ginseng may also have this effect, combining the two can cause blood sugar to dip too low.
- Taking caffeine and ginseng may be over-stimulatory and/or cause increased heart rate and blood pressure.
- Ginseng may decrease how quickly the liver breaks down certain medications, so taking the supplement with medications that interact with the liver — and many if not most are — may cause or worsen side effects.
- Because both ginseng and some antidepressants can act as stimulants, taking the two together might produce too much stimulation and cause anxiety, insomnia, and other side effects.
- Because it may increase blood flow, ginseng may decrease the effectiveness of medications used to slow blood clotting, such as Warfarin.
This list is not exhaustive; speak with your physician before taking ginseng.
- Don’t confuse Panax ginseng, also called True Ginseng or Wild Ginseng, with Siberian ginseng or American ginseng. American ginseng has less research supporting its use and Siberian ginseng belongs to a different plant family.
- Remember to look for the percentage of ginsenosides on the label — a minimum of 3 percent is critical.
- Many ginseng products aren’t vegetarian friendly. Check the ingredients to make sure the capsule isn’t made from gelatin if this is important to you.
- Some people experience adverse reactions to ginseng, such as anxiety and sleeplessness. It may be prudent to start with smaller doses and slowly increase over time.
- Ginseng is often paired with Ginkgo Biloba, as this herb has traditionally been used for the same reasons as ginseng. Some research suggests combining the two may amplify the improvement to reaction time, but possibly at the expense of accuracy in memory recall.(11) For now, more research is needed.
There are a lot of different companies with wildly different approaches to formulating their ginseng supplements. The tips outlined in this article will help you to be more discerning and to pick the best supplement for your own needs. Just remember to speak with your doctor before undertaking any new supplement regimen.
