I think it's the combination of the IP6, and the BE.
This is the IP6 I've been using. Here's what it says for dosage/time to take it. Best time is first thing in the morning when you get up. It's hard to fit it in the rest of the day.
>>>Take 1 to 6 capsules per day on an empty stomach, or as directed by your qualified health care consultant. DO NOT take at the same time of day as minerals or medications. IP6 is an efficient mineral chelator and therefore should be taken only on an empty stomach
