OK so I looked over those vitamin supplements, here's what I see:
the Be-Enhanced is just an Omega 3-6-9 supplement. Omegas are one of the "optional" supplements that IP offers, I take a basic fish oil pill for my Omega 3's. So no issues there
The Be-Energized is B-3 and caffeine. Don't see a problem with this one, other than if you are taking a caffeine pill you will have to increase your water intake to offset the diuretic effect. Same as if you had more than one cup of coffee in a day.
The Be-Defined is the one I'd avoid. First, we are already taking a potassium supplement. Potassium is one of those minerals you CAN have too much of - it can cause issues with your kidneys. Between the supplements and the large amounts of protein we eat, we are already taxing our kidneys a little on IP (That is one reason it's not safe for people with existing kidney or liver issues). Also, the FORM is an issue - potassium chloride is harder for your body to break down. The IP supplement is potassium bicarbonate, which is MUCH gentler on your system as it is the broken-down version of potassium gluconate. Easier for your kidneys to process, and safer in light of the whole IP picture.
