Greetings, and thank you for your question! These are both excellent questions. The short answer is, yes, it is ok to take both together, presuming there is no medical contraindication against doing so (like having heart troubles, such as rapid heart rate). There are guidelines for doing so, and it is quite safe if done correctly (I have many patients who do something like this). There is more to add, but I see you are offline right now. Please let me know when you are on again, so I can assist you.
