Let’s be honest, if you’ve spent any amount of time in the kratom community you’ve undoubtedly grown tired of the traditional kratom strains. They’re still awesome and they serve their individual purposes, but maybe tolerance or complacency has set in and it’s just not doing it for you like it used to.

Maybe someone hipped you to the term “hulu kapuas” and you’re intrigued. But where to start? Well, my friend, you’ve come to the right place. In the following guide, we’ll cover everything you need to know about this new and exciting kratom strain.

For starters, you’re probably wondering if Hulu Kapuas is just some fancy name a vendor came up with or if it’s a unique strain all its own. Both may be true, depending on what online vendor you’re dealing with. However, pure Hulu Kapuas Kratom is most definitely its very own strain.

Let’s explore the origins before we get into the particulars.


A modification of the average kratom strain, Hulu Kapuas is carefully cultivated in the dense forests of Indonesia where experienced farmers harvest the most mature plants from their location by the riverbanks of the Kapuas River (hence the name).

These plants are extremely rare due to the fact that the island is barely populated by humans. Those who venture there are adept in the art of growing live kratom plants. These individuals have developed intricate methods by which to ensure optimal alkaloid levels.

The relative isolation of these kratom plants means that they are seldom found in wholesale kratom stores, making them a much sought-after property. The scarcity and difficulty of sourcing Hulus Kapuas Kratom owes to its obscurity. Vendors are only now catching on to its immense popularity among serious kratom enthusiasts and, as such, they are having to pay top dollar to find Hulus Kapuas Kratom leaves.


Every strain has its own purported benefits and effects. The properties responsible for these effects are the alkaloids contained within the raw kratom leaves. There are varying concentrations of these alkaloids in each strain and the region/soil in which they grow is of paramount importance to that.

In the case of Hulu Kapuas, these are the rich and powerful alkaloids contained within the kratom powder:

  • Corynantheidine
  • Corinoxin
  • Corynoxein
  • Epicatechin
  • Isomitraphyllin
  • 3-Isocorynantheidin
  • 3-Dehydromitragynin
  • 7-acetoxy mitragynine
  • Mitraciliatin
  • Mitrafolin
  • Mitragynine
  • Mitraphyilline
  • Mitraspecin
  • Mitraversin
  • Paynanthein
  • Speciofolin
  • Speciogynin
  • Specionoxein
  • Stipulatin

Many of these active alkaloids are either not present in traditional kratom strains or occur in such small percentages that they hardly play a role in those strains’ effects. The common kratom strain contains large concentrations of Mitragynine and 7-hydoxymitragynine, an analgesic and a sedative, respectively.

Hulu Kapuas Kratom’s alkaloids serve a range of purposes with some acting as antioxidants and others as anti-inflammatories. Each of these alkaloids contributes to Hulu Kapuas potential for muscle relaxation, diarrhea relief, anxiety relief, stimulation and more.

The precise alkaloid profile varies depending upon the vein color of the strain, but all share similar attributes in common.

What sets Hulu Kapuas apart from other strains is its reputation as a fusion form of kratom, meaning that it combines the best traits of all kratom plants. For instance, some strains are most effective as stimulants while others are more sedating in nature. Hulu Kapuas, on the other hand, acts as both at different dosages.


There are three different vein colors in the Hulus Kapuas family—Green Hulu Kapuas, Red Hulu Kapuas and White Hulu Kapuas. All three are very much alike save for a few minor differences. The perfect example is Green Hulu Kapuas which has its own prominent effects but encompasses many of the qualities inherent in the white vein Hulu Kapuas strain.

Here is a full list of their most common traits.


Green Hulu Kapuas is a potent relaxant which has been used to improve mood, calm nerves and induce a restful night’s sleep. It is enjoyed by those afflicted with insomnia as well as individuals with anxiety disorders. Notable effects include increased sociability, alleviation of tension and positive mindset. Like White Hulu Kapuas, it may also offer moderate stimulation.


A milder strain with more minimal effects, Red Hulu Kapuas is a great strain for beginners. While it hasn’t been embraced by the kratom community at large, Red Hulu Kapuas is nonetheless an effective form of kratom for those who want the kind of stimulation associated with coffee minus the jitters and nervousness.

At certain dosages, Red Hulu Kapuas is also somewhat relaxing and sedating. Bear in mind that dosage is always an important factor to consider and one that varies depending upon one’s personal physical makeup and sensitivity.


This is my personal favorite and one that is worth talking about at length. A perfect blend of kratom’s greatest hits, so to speak, White Hulu Kapuas refreshes the body and mind with its unique alkaloid profile and host of purported benefits.

Whenever I’ve burned White Hulu Kapuas, I end up feeling more chill than my worry wart ass ever feels normally. Like soaking in a warm bath with incense burning and some blissful lo-fi playing on my iPod, this one brings me right to my Zen place. If it were a penguin, it would be my spirit animal.

The interesting thing about this one is that, at the right dosage, it can also give you that extra bit of energy you need to get up and go. I usually burn some right before I hit the gym or head out to go cycling. The innate anti-inflammatory alkaloids work wonders when your calves are burning from a long jog or a series of reps.

White Hulu Kapuas’ effects may include any or all of the following:

  • Relief from Depression
  • Increased sociability
  • Sharpened focus
  • Clean energy boost
  • Stress relief
  • Restful sleep


Finding the proper dosage can be tough because everyone’s different, but popular opinion suggests that first-time users should burn 2-3 grams when starting out. This is widely considered a threshold dose that will unlock Hulu Kapuas Kratom’s fundamental benefits without going overboard.

Once acclimated, most kratom users burn 3-5 grams for moderate effects while seasoned users often burn as much as 7 grams to attain its most substantial effects. Caveat: At 7-10 grams, the likelihood of side effects increases by 100 percent, so be careful.


Hulu Kapuas is a remarkable strain that is well worth checking out, but all who burn it need to enjoy this aromatic botanical with caution. Be safe, be smart and be well.
