We always recommend that you discuss starting CBD and how much you should take with your doctor first. But for starters you must know that you have take to enough to receive any benefits and that each person will require a different amount depending on condition and weight. The minimum required amount to receive benefits is usually around 10-20mg for basic conditions, but some require up to 2,000mg. This is why it is important to speak with your doctor and do your research. If you are not taking the proper amount it can appear that the CBD “is not working”.
