What Is Green Riau Kratom?

Kratom (Mitragyna speciosa) is an herb native to Southeast Asia and is widely used as traditional medicine. It grows primarily in Thailand and Malaysia and comes in three main varieties: white-vein, green-vein, and red-vein. Each strain is produced using different farming and harvesting techniques and has unique effects.

As kratom plants age, they progress through different color stages.

White Strains

Young, immature plants have leaves with lightly colored white veins and produce white-vein kratom strains when harvested.

Red Strains

A fully mature specimen’s leaves have veins with a reddish hue and, unsurprisingly, produce red-vein kratom.

Green Strains

Plants that have matured past the white stage but have yet to reach complete maturity are the green-vein strains.

Green-vein kratom strains generally have a balanced profile, providing a bit of everything that kratom has to offer. These usually provide mild pain relief and stimulation, although not as much as the red and white strains.

Many users regard green-vein kratom as the best choice since it doesn’t overemphasize stimulation or sedation. Most people also recommend beginners start with green-vein kratom since some strains can be overwhelming for new users.

Green Riau Kratom is a specific green-vein strain grown along the Riau River in Indonesia. It’s a more potent green strain with more powerful effects and a shorter lifespan. It is still more balanced than most red and white strains but perhaps not the best choice for people without a little experience.

What Does Green Riau Kratom Do?

As a green strain, Green Riau kratom contains moderate amounts of both mitragynine and 7-hydroxymitragynine. Mitragynine dominates 7-hydroxymitragynine in all kratom strains in terms of concentration, but some strains emphasize the effects of one more than the other.

Green Riau skews towards the red-vein end of the spectrum, providing more analgesic effects and relaxation than your average green strain. With that said, it’s still more energizing than virtually all red-vein strains, so taking it at night can make it difficult to sleep for some people.

Many Green Riau users say the effects roughly break down to about 60% relaxing and 40% energizing, describing their headspace as relaxed but alert. You can vary the impact slightly by altering your dose, which we will discuss in-depth in a later section.

Green Riau Kratom Specs & Rating

  • Energy ⭐⭐ —Green Riau kratom is slightly energizing but favors relaxation more than the average green-vein strain.
  • Mood ⭐⭐⭐⭐⭐ —Many Green Riau kratom users love how it affects their mood, describing the blend of relaxation and mild energy as modulating and enjoyable.
  • Pain Relief ⭐⭐⭐ —Green Riau kratom provides more pain relief than a typical green strain but can’t compete with most red-vein strains. Most Green Riau users say it’s perfect for mild pain but may not be strong enough for more severe cases.
  • Anxiety Relief ⭐⭐⭐⭐⭐ —Green Riau is great for anxiety relief, striking the right combination of calm and focus for many people.
  • Sedation ⭐⭐⭐ —Although Green Riau kratom is not as sedating as red kratom strains, it’s still considerably more relaxing than many green strains.


Many people recommend Green Riau kratom for people who find red-vein kratom too sedating but still want more relaxation than an average green-vein strain can provide.

Most Green Riau users report feeling relaxed and happy, although they warn against taking it before bed since it provides enough energy to prevent some people from sleeping soundly.

Some people describe Green Riau’s effects as being like drinking a cup of tea where the L-theanine and caffeine combine to produce a calm, alert mental state.

Improved Mood

White-vein kratom is often the go-to kratom strain for improving one’s mood, but Green Riau kratom can also help users find motivation and positivity.

The primary difference is that Green Riau creates a better outlook by providing mental calmness, and white-vein strains usually improve outlook by directly boosting energy and motivation.

Pain Relief

Green Riau kratom gets more of its effects from 7-hydroxymitragynine than many other green-vein strains, making it more sedating and a better pain reliever.

It’s an excellent choice for people with mild to moderate pain who find that ordinary green strains don’t offer enough relief. However, for extreme pain, most people still prefer red strains.

Green Riau Kratom Dose

Green Riau kratom dosing follows the general kratom dosing guidelines.

Low doses in the 1-3 g range lead to more pronounced stimulation, 3-6 g doses offer a blend of stimulation and sedation, and amounts from 6-10 g are more intensely sedating.

Here are some dosing tips specific to Green Riau kratom, but remember that everyone is different, and it’s best to start on the low end to avoid side effects.

Dose for Mild Relaxation

Most experienced users find that taking around 5 g gives them the desired amount of relaxation they’re looking for without making them feel tired. Some people prefer slightly lower doses in the 3-5 g range, but lower than that becomes too stimulating.

Dose for Improved Mood

Taking low doses in the 1-3 g range is best for people looking to improve their mood. Green Riau is a fairly even blend of relaxing and energizing at this level.

Most people find its balance of energy and focus pleasurable and prefer it to higher doses.

Dose for Pain Relief

Higher doses do the opposite of low doses, making Green Riau more sedating and offering more substantial analgesic effects.

Taking between 6 and 10 g provides significant pain relief appropriate for managing moderate pain. Doses above 6 g are very relaxing and aren’t recommended when focus and mental clarity are required.

Side Effects of Green Riau Kratom

Green Riau Kratom comes with several possible side effects that become more likely with larger doses. The most commonly experienced side effects are lethargy and nausea. Both are drastically more common when taking large amounts, typically around 10 g or more.

Prolonged Green Riau use without breaks can lead to systemic fatigue and an overall feeling of tiredness. It is important to limit your weekly kratom use to no more than 4-5 days per week. Experts also recommend taking at least one week off every two months.

Taking regular breaks and limiting your weekly use are the best ways to avoid kratom’s most serious risk: addiction.

Even though kratom is not an opiate, it has similar effects on the human body, and it is frighteningly easy to develop a dependence. Experienced kratom users agree that the best way to combat addiction is to stick to a schedule and limit regular use.

Similar Kratom Strains

Green Riau Kratom is a rare and highly-sought strain, making it somewhat expensive and difficult to obtain. Here are a few similar strains that offer comparable effects to Green Riau kratom.

Green Malay Kratom

Green Malay Kratom is a more soothing strain like Green Riau, although it doesn’t offer quite as much pain relief. Proponents of Green Malay say it’s one of the best strains for relaxation and euphoria and great for treating anxiety.

Green Borneo Kratom

Green Borneo Kratom is more of a standard green-vein strain, giving users a relatively balanced experience. Green Borneo fans say it does many things well but doesn’t excel in any one area, making it perfect for people looking for an all-purpose strain.

Red Bali Kratom

Even though Red Bali is a red strain, it’s a more mild red strain, making it a viable alternative to Green Riau. Red Bali is great for people looking for a daytime pain-reliever since it’s significantly less potent than many other red strains. Red Bali is considered a bit more stimulative but provides pain relief.

Final Thoughts: Green Riau Kratom

Green Riau provides the balanced effects profile of green-vein kratom but slightly emphasizes relaxation over stimulation. It’s a good pain reliever that works better than most green strains but not quite as well as red-vein strains, making it suitable for relieving moderate pain.

Using Green Riau kratom safely and effectively requires taking regular breaks and regulating your dose size to match your desired effects. There are few side effects of using Green Riau kratom, although nausea and lethargy are common, especially at higher doses.

Green Riau Kratom is a less well-known strain, making it hard to get and fairly expensive. If you’re looking for a more soothing green strain, consider Green Malay or Green Borneo kratom instead.

For even more pain relief and a more intensely sedating experience, Red Bali is a good choice.
