Most of the Kratom strains have similar recommended doses. It usually depends on age, sex, and health status.
However, the concentration of beneficial compounds found in kratom extract is different. This difference in concentration makes it more effective than kratom powder. Taking the same dosage for both products can cause side effects.
For kratom powder, the regular dose lies somewhat between 1 to 2 grams. However, it can be more tricky to decide the dosage for kratom extract. This is because the extract is measured in 2x, 5x, 10x. The correct dosage for the extract varies depending on physical conditions.
Take a smaller amount of extract initially and then increase the dose over time. To find the best dosage for you, examine your reactions in every dose.
