The risk of taking 2 capsules together is that it is double the dose and the label clearly indicates this should only be done under the supervision of a doctor. And...it's doubles the chances of gettting TE's.
Meals should be at least 4 hours apart, and snacks should be limited to 1 to 2 grams of fat. Otherwise, the body might see it as one meal - especially if someone has a slow digestive tract - and TE's could result.
I hope this helps. Please let me know if you need anything else.
