How Strains Are Named
The majority of Kratom strains are named according to their vein color and origin. For example, Bali Red Vein is a red variety sourced from the island of Bali. Most Kratom comes from Southeastern Asia, so you’re going to see types of Kratom primarily from that region of the world.
Vein Colors
While research is still ongoing as to why Kratom strain effects vary depending on the color of the plant’s veins, scientists believe that the vein color is directly related to the plant’s maturity. White vein plants are youngest and reds are most mature, with green vein varieties sitting right in the middle. Let’s take a look at how the types of Kratom vary in their effects based on vein color.
Red 
Red vein Kratom tends to produce the slowest effects. Red strains are known by users to be the most relaxing and sedating options, perfect for people who are looking to relax after a long day or combat sleeplessness.
Red vein types of Kratom also usually have the best analgesic properties, so they’re ideal for users who are looking for relief from chronic or acute aches and pains. While Kratom is not an opioid, it does produce effects most closely associated with opioids, so it’s a popular choice for those who are trying to fight withdrawals from opiates.
White
White vein Kratom is usually the fastest and most energizing out of all of the types of Kratom. Kratom enthusiasts frequently turn to white vein strains when they need a pick-me-up in the morning or during the workday. Many users prefer the clean, jitter-free boost that white vein Kratom provides compared to coffee.
It’s worth noting that white vein Kratom strain effects do vary, and they can still be relaxing and analgesic at higher doses. However, if your main reason for using Kratom is to improve motivation, focus, and concentration, white veins are a great starting point.
Green
Green types of Kratom provide a nice middle ground between reds and whites. Green Kratom is quite versatile, boosting energy in low doses and sedating in higher doses. Many users report that green varieties offer the most euphoria and mood boost, and it’s a popular choice for those who are hoping to relieve anxiety or use Kratom for enhancing social situations.
