Kratom is a tree from the coffee family that grows in Southeast Asia. Its scientific name is Mitragyna speciosa. It is mainly found in Thailand, Malaysia, and Indonesia. Its leaves are dried and used to make tea, sold as powders, capsules, or extracts. In some cases, kratom leaves are also smoked like tobacco. Kratom comes in different strains, and each one works in its own way. Some strains boost energy and focus, while others help with relaxation and calmness. Knowing the difference is important because the strain you choose will shape your overall experience.

What are kratom strains chart?

A kratom strain simply means the type of kratom leaf you’re using. The way the leaves are dried or fermented gives them their colour—red, green, white, or yellow. The region where they grow shapes the mood and taste, since soil, sunlight, and climate change the alkaloid balance. That’s why no two strains feel exactly the same.

Kratom strains chart based on vein colours

Red vein kratom

Red vein kratom is easy to recognize by its red-coloured veins. It is usually dried indoors with little or no sunlight, which helps preserve its alkaloid structure. Red strains have a higher concentration of 7-hydroxymitragynine (about 2% or more) and lower mitragynine (around 10–12%). That is why they are considered heavier in profile compared to other types. 

Green vein kratom

Green vein kratom comes from leaves with green veins and is dried both indoors and outdoors, which balances its alkaloid levels. Greens typically contain 15–20% mitragynine and 0.5–1.5% 7-hydroxymitragynine. As a result, they fall between red and white strains in terms of overall character. Therefore, many users view green strains as a balanced choice.

White vein kratom

White vein kratom has pale veins and is usually dried in direct sunlight, sometimes followed by fermentation. This process increases the sharper alkaloid content, with mitragynine levels around 20–25% and very low 7-hydroxymitragynine (less than 0.5%). That is why whites are often considered brighter and more stimulating in profile. 

Yellow/gold vein kratom

Yellow and gold kratom are not natural vein colours but are created through special processing. Some leaves are fermented, while others are dried for longer periods or blended from different vein types. This method changes the alkaloid balance, giving them 12–15% mitragynine and about 1% 7-hydroxymitragynine. Therefore, they are seen as smoother and more subtle compared to reds and whites. 

Strains of Kratom based on regions

The region where kratom grows has a strong impact on its character. Soil type, rainfall, and climate affect the alkaloid profile, as well as the taste and mood of the strain. Rich volcanic soils can create smoother and more balanced leaves, while sandy soils tend to give a sharper and more stimulating edge. This is why the same vein colour can feel different when grown in Bali, Borneo, or Thailand.

Bali kratom

Bali kratom grows on the Indonesian island of Bali, where the rich soil and humid weather create leaves with a balanced profile. That is why Bali kratom is considered one of the most versatile types. Red Bali is often seen as heavier, while Green and White Bali feel lighter and more uplifting. Many people view Bali as a reliable all-rounder.

Borneo kratom

Borneo kratom comes from the island of Borneo, one of the largest islands in Southeast Asia. The tropical climate and dense forests give these leaves a smoother but stronger character compared to Bali. As a result, Borneo strains are often chosen by people who want something deeper and heavier in profile.

Maeng da kratom

Maeng Da kratom is different from most other strains because it was created through selective breeding in Thailand to increase strength. Later, it was also grown in Indonesia, where it became widely available. That is why Maeng Da is considered one of the most powerful kratom types.

Super Malay kratom

Malay Super kratom is grown in Malaysia, where the climate helps the leaves develop a longer-lasting profile. Green Malay is especially popular because it is steady and consistent, making it stand out among regional strains. That is why Malay kratom has a strong reputation for reliability.

Thai kratom

Thai kratom originates from Thailand, where hot and sunny conditions give the leaves a sharper and more stimulating profile. Therefore, Thai kratom is often chosen for tasks that need more endurance and focus. Over time, it has become one of the best-known kratom varieties worldwide.

Indo Hulu kratom

Indo Hulu kratom comes from Indonesia, one of the world’s biggest kratom producers. Because it grows in many regions, Indo kratom can vary, but it is usually smoother and less intense compared to Thai or Maeng Da. That is why Indo strains are often recommended for people new to kratom.

It's important to note here that these numbers are approximate ranges based on common lab reports; actual levels can vary by harvest, soil, and processing methods.

How can you choose the right kratom strain?

Picking the right kratom strain is less about rules and more about matching your lifestyle. Some people choose by time of day like lighter strains in the morning, steadier ones in the afternoon, and heavier ones at night. Others go by taste and smoothness, since certain strains are earthier or more bitter than others. Many regular users even rotate strains, so their body doesn’t get used to just one type.
