White vein kratom is known as a stimulant and positive mood enhancer. The effect of each strain off course depends on numerous factors such as the quality of the product, lifestyle and tolerance level of the individual. However, the trend is that the white veins are most stimulating and euphoric of all kratom strains. White kratom is increasingly taken instead of coffee (caffeine) for alertness, concentration and cheerfulness. Many have come to take white kratom for increased concentration, motivation and stamina during long working days.
