The effects of kratom on your health varies from individual to individual. If you look at the historical use of kratom, you will find a lot of information on how people native to South-East Asia, use kratom for issues like fatigue, pain, and euphoria.
However, there are many ways to figure out what is the right recommended dosage for them. That is to start with the lowest amount of whatever strain and form you are taking. For example, with kratom capsules, you should start with a low dose (1). For those who take kratom powder, it is best to buy a digital scale to weigh the dosage. Again, with every kratom product, it best to be cautious with how much you are taking.
