GS15-4 Panax Ginseng Extract Powder

Ginseng has been used for centuries as an important component of traditional Chinese practices and includes 11 species. Panax ginseng, also referred to as true ginseng, is one of the most common, well-researched species. Panax ginseng presents a variety of uses for numerous ailments.

While panax ginseng was traditionally dried or brewed as a tea, it has since been extracted into more concentrated forms. GS15-4 is an extract of panax ginseng that presents many of the potential benefits of ginseng.

GS15-4 Panax Ginseng Extract Uses and Benefits

In studies, panax ginseng has primarily been found to boost the health of your whole body, potentially recalibrating and normalizing bodily functions that may not be operating optimally.* Panax ginseng shows potential positive effects for supporting inflammation.*

Studies also show that panax ginseng may help to repair and improve the immune system as a whole.* Researchers have found that taking panax ginseng may help increase the number of immune cells. This has led to studies suggesting that panax ginseng extract benefits may include:

  • May help promote energy levels*
  • May help support focus and cognitive function*
  • May help promote metabolic function*
  • May help support immune system function*

One study found that participants who took panax ginseng experienced metabolic/glucose support.* Early studies have also found panax ginseng’s potential for promoting overall brain health.*

Research shows that panax ginseng may promote healthy levels of oxidation.* Harmful compounds known as free radicals, are created naturally during the process of cellular oxidation. Free radicals have been shown to damage cellular membranes and mutate DNA.

Many studies have found panax ginseng to be a viable adaptogen.* This means that panax ginseng may help you adapt to stress and limit the physical and emotional damage caused by stress.* Panax ginseng may also have a calming effect on the body and mind and potentially promote better sleep quality.*

Panax ginseng also shows potential for improving cognitive health and mental processes.* Research has also found that the Rg1 group of ginsenosides in ginseng may be responsible for improving maintenance processes in your neurons while supporting cognitive functions. One study suggested that panax ginseng has the potential to improve performance in tasks requiring high levels of cognitive function for prolonged periods of time. Panax ginseng has been shown to improve both spatial and working memory.* Studies also show that this root may improve focus, concentration, and thinking abilities. Additionally, GS15-4 panax ginseng extract benefits may apply to athletic performance as well. The root extract may also increase stamina and energy levels and help regulate metabolism so using panax ginseng may potentially lower your recovery time and muscle fatigue.

How GS15-4 Panax Ginseng Extract Powder Works

Panax ginseng roots contain triterpenoid saponins called ginsenosides. Many other species of ginseng lack these ginsenoside compounds. Ginsenosides are the main active compound in panax ginseng, responsible for the reported effects and benefits of the root.

Why GS15-4 Panax Ginseng Extract is the Superior Panax Ginseng

GS15-4, “the 21st Century Ginseng Extract,” is a patented breakthrough technology using enzyme fermentation to produce a completely balanced ginseng extract in its end-stage metabolite form. The Result is a completely-balanced, high-absorption, high-efficacy panax ginseng extract for optimal energy, adrenal function, mental and physical performance, blood glucose regulation, immune health and overall well-being.*

GS15-4 has been clinically proven to provide 15 times increased absorption, 4 times faster absorption and 4 times more consistent absorption. Winner of the BEST BOTANICAL 2012 at Expo West /Engredea, this unique ginseng extract delivers ginseng with higher efficacy, more consistent absorption, and an improved taste profile compared to conventional ginseng extracts.*

Proprietary Processing

  • Low heat vacuum extraction of whole root. This maintains the vitamins, amino acid profile and organic germanium lost in the high heat steaming process used by traditional processing.
  • No peeling. Peeling removes the minor rootlets and hair rootlets that carry key bioactive compounds.
  • Optimal harvest time. The roots are harvested at the optimum time of 4 to 5 years. In comparison, red ginseng extract available from most companies uses the traditional 6-year harvested root.
  • Proprietary enzyme fermentation process improves absorption. Ilhwa scientists discovered that some of the key ginsenosides, the unique active compounds, are not fully absorbed until they reach the lower intestine, where the beneficial bacteria residing in the large intestine play a very important role in metabolizing natural ginsenosides into highly absorbable compounds. High-yield enzyme fermentation mimics the fermentation that occurs in the intestine to produce the end-stage metabolite which has been clinically proven to have better, faster, more consistent absorption.


As a dietary supplement, take 200mg of GS15-4 Panax Ginseng Extract 1-3 times daily.

    Works great...

    ..however it may be my own fault but the powder became a "soft clumpy". I must have not stored it in a cold and dry enough area. Maybe capsules next time for me.

    Added this to my morning stack. I can safely say I could drop one or more other energy focused supplements. 4 hours of clean drive , dont forget to eat with it!

    GS15-4 Panax Ginseng Extract Review

    This was my first time using the GS15-4 Panax Ginseng Extract. I'm not sure if I personally can confidently say I noticed any effects as a result of supplementing it, however I can certainly ascertain that it tastes great (in my opinion). I would not purchase again as I didn't notice much of an effect from the Ginseng (perhaps I should try others) and I find the product rather expensive considering that.

    Good For My Variety of Tinnitus "Pain"

    The kind of tinnitus I have is centered around my temple. I have pain around the ear. I have hyperacusis. If you learn what drugs and foods and substances to cut out of your life, this helps with the discomfort in my head. Oleamide, Taurine, and L-Theanine for sleep. Also 50 - 75 mg of amitriptyline helps this kind of tinnitus and getting to sleep. Many supplements make my kind of tinnitus worse. Such as too much magnesium, curcumin,Boswelia and many others. Very occasional high dose meltaonin. Interrupted by nootropicsdepot melatonin capsules, and also total breaks from it as well. This is the best ginseng in the world. But it is way too expensive for me. 1 star off for the price, but that is not nootropicsdpot's fault, but that of the supplier.

    Amazing Ginseng

    This is by far one of my favorite ginsengs out there. I love the energy it gives me without the jittery feeling. It also seems to boost my immune system while taking it. Great natural product.

    Ginseng heals the brain from injuries

    I didn't think it would work so fast but this stuff is making me feel like I did before I suffered some head injuries. It's been experimentally proven to work in high doses in two weeks, repairing the hippocampi of rodents, but I think I've been taking it for only ONE week. This stuff is great: take it in the morning, take it at night, take it in the middle of the day. You just can't regret having taken it. I tried gas station ginseng once and I got really strong effects-I had to stop driving because it was so intense. After trying this stuff I'm either convinced my head injury must have been REALLY bad or that the gas station ginseng had an adulterant in it. (which is not unheard of) Anyway this stuff is great. If I take too much, I get kind of sluggish. And pretty hungry. I think I must be getting healthier from having taken it. I really feel like I'm healing because of it. Good combination with polygala. If I take this, I don't need to drink coffee.

    Excellent Ginseng

    This is an an excellent ginseng that provides a nice boost of energy that lasts. The powder is a great addition to a morning smoothie and makes it easy to customize a dosage that works for you.

    I love this Ginseng.

    I love this ginseng, it provides a boost in energy, both mentally and physically. helps keep me from over reacting to situations, especially while driving long distances. I also love the other ND Panax Ginseng root extract and often combine them. I don't take it on a daily basis, I will usually take it 2-3 days then take a 1-3 day break.

    So, I just received this product and started using it with a couple of other nootropics, so I will not make any comments about the effects of this, for now at least, because its both too soon and hard to define which effect comes specifically from this product. However, I am very dissatisfied by two things already. 1- The powder is VERY insoluble in water. I don't know if it was because of temperature variations during the overseas shipping, but the powder has hardened into solid rocks, and its very hard to dissolve that. I this powder is supposed to be dissolved using a particular method, it should be previously stated! The product description here says it has exceptional absorption, but its so insoluble that its hard to believe that. 2- I honestly don't understand why it's so hard for the producers/Company to just kindly provide a scaled scoop to handle the powder. I mean, how hard would it be to just give a scoop measuring exactly 200mg of that specific powder, so that I wouldn't completely depend on a weighing machine So far I haven't been able to access the effects, I shall write another review covering this when the time comes ND Admin: Panax ginseng root always clumps, no matter what type of extract it is. That's just a normal property of the extracts of panax ginseng root. Extracts of the leaves do not have that problem. So if clumping is a big issue, we suggest going with the leaf extract instead. Regarding scoops, they are not accurate forms of measurement. Powders vary in density based on milling size, which can change batch-to-batch. Accuracy in dosing matters. We feel it is irresponsible to continually promote the use of scoops as instruments of dosing, as they are NOT accurate. Weight-based dosing is always going to be more accurate than volumetric dosing. We always suggest using a milligram scale for measuring powders. We offer this product in capsules if weighing the powder is not an option.

    No tranfer scoop?

    I'm giving 4 stars because I have bought this extract in liquid form directly from Ilhwa before, and it is very good. BUT I am removing a star because the package is misleading: Why write that the transfer scoop isn't accurate, if there it no transfer scoop at all? I am very disappointed because now I have to use a scale and I don't have ustensils that are really adequate, I will lose a lot of time and probably a part of the product. I didn't mind not getting exactly 200 mg on every dose, but I do mind having to weight my doses everyday.

    Its definately way more pure than one's on amazon

    My jar has been with me for weeks and I still have plenty left. This is due to I think the purity and how fast it works. I use it in the afternoon when I start to get that mental fatigue. However I would say that like most ginseng its going to diminish in effectiveness after 6-8 weeks of use. Consult or pubmed.

    Nice Boost of Energy

    I take 200 mg in the morning before work as well as my 1-3 polygala tenuifolia 10:1 capsules throughout the day and I feel a very sustained energy. Its a very nice blend and it tastes very well. I highly recommend.

    Buying another bucket now

    About to buy again, should say it all. I take a lot of nootropics, this tends to be at the core of every batch I make. Hard to quantify or correlate its exact value when there are so many variables. N=1 seems to hold value & has me hitting the buy button again.

    Good, but poor stomach tolerance for me!

    I did notice a subtle energy boost, but did experience bloating at modest doses (200mg.) At least this kept my appetite at bay...!

    Great Stuff...

    The GS15-4 gives you subtle energy. Something you can feel but not overwhelming like straight caffeine. I'm looking forward to trying other Ginseng products from Nootropics Depot. As always it got to me quickly

    Great Product

    Great product. I love this product for mental and physical energy. Also helps with recouperation after a serious workout.

    Good, well balanced

    This is an excellent substance and feels more "well rounded" and balanced than a lot of the commercial ginseng's that have have an edgier, speedier feel. This one enhances well being. Having said that I like to combine 200 mg of this extract with about 75mg of the more stimulating leaf extract that ND also sells. I can go all day with that combo.
