ISOL-8 Kratom Extract: What is It and is It Worth the Price?

November 21, 2018 Articles, Kratom Alkaloids, Kratom Research, Kratom Reviews, Kratom Strains

In the past, we’ve talked about things like UEI (Ultra Enhanced Indo) and how it compares to regular kratom powder. We’ve also given our readers an exploded view of kratom extracts in our comprehensive guide.

But the times they are a-changin’ and perhaps that guide wasn’t comprehensive enough.

As we speak, hundreds in the kratom community have begun stocking up on the curiously named ISOL-8, a relatively new kratom extract that’s generating some major buzz in the kratom industry. Today we’ll do a deep dive on this curious product and tell you all about why it may or may not be appealing to you.

Let’s roll!


It’s been called a “standard extract,” but I would argue that it is anything but. Whereas kratom extracts like UEI contain high levels of all active alkaloids, ISOL-8 is specifically standardized to contain a minimum of 8% mitragynine, the indole-based agonist that normally occurs at 1.2-2.1% in dry kratom leaf.

Mitragynine is a dynamic alkaloid which possesses exceptional analgesic properties. In low concentrations, mitragynine induces clean energy, mild stimulation and a sense of euphoria. At larger doses, it has antinociceptive effects and can be rather sedating.

Obviously, given the sheer volume of mitragynine present in ISOL-8, its sedating effects can be quite profound. This is one of the reasons why it has attracted a lot of attention of late.

ISOL-8 is the one kratom extract currently on the market that elicits caffeine-like effects with a substantive energy boost. At a responsible dosage, users report hours upon hours of endurance, increased attention and significant stimulation.

ISOL-8 is made from several different kratom strains, resulting in a high volume of numerous naturally-occuring alkaloids. The process by which this extract is prepared makes it more of an isolate than your typical kratom tincture.

Each ISOL-8 kratom extract may contain as much as 12.5% mitragynine which is, by far, the highest concentration I’ve come across. Unlike other extracts, its purported effects tend to come in waves with a longer duration than most.


If you haven’t already figured it out, ISOL-8 is becoming massively popular because of its very specific and acute effects. While other extracts yield a broad range of effects, ISOL-8 targets a precise area and zeroes in on just what certain people want out of an extract.

You get all of the attentiveness, sharpened focus and alertness of a good caffeine buzz without the jitters, nausea or jumpiness of the same. This makes sense given that kratom comes from the coffee family of plants and is, therefore, meant to stimulate.

Due to the nature of its preparation, ISOL-8 kratom extract is rare when compared to your average kratom strain, thus making it a must-have item for serious kratomites.


This is where you encounter some potential downsides; some in the community have said that ISOL-8 extract isn’t that great. One user over at Blue Light wrote, “tried it…not as good as uei…not really worth the money.”

But elsewhere, a user said quite the opposite; this person writes, “…price wise this is wayyy more affordabe than uei.”

Of course, this has less to do with the quality of genuine ISOL-8 Kratom Extract and more to do with the vendor you’re buying from. As with almost any kratom product, prices vary from vendor to vendor. Finding an affordable option online may seem confusing, but it’s really just a matter of shopping around.

As far as the efficacy of ISOL-8, the people have spoken. One user on Reddit wrote, “I tried the ISOL8 from SpeciosaPro and it’s my favorite extract. I have a decent tolerance and will take a gram or more of any other extract, even UEI, and be good to go. With ISOL, I only needed about .7g. On top of that, it gave a more well-rounded feel than other extracts. It felt like I had taken a bunch of plain leaf.”


ISOL-8 isn’t nearly as prevalent as UEI and other kratom tinctures, but there are a few good spots where you can pick some up. Of the six that I’ve explored, I’ve narrowed my recommendations down to the following three:

  • Phytoextractum
  • Get Kratom
  • Legal Herb Shop

With online stores like Phytoextractum, you’ll get guaranteed quality or your money back. You’ll also deal with knowledgeable and reasonable people who are committed to customer care.


Prices vary from vendor to vendor, but the average price point is around 20 bucks for 4-5 grams. Some vendors offer deep discounts when customers buy bulk kratom extract.


When one considers how little it takes for ISOL-8 to pack a punch compared to traditional kratom powder, it is well worth the money. Give it a go today and see if it’s right for you. Is it as good as UEI? Do you find that it’s better than UEI? Let us know what you think in the comments below. Happy Kbombing, boys and girls! ; )
