The first day I took Bioperine I in the morning, with my vitamins and with my treatment (designed for regulate my heart beats). My pulses decreased falling from 60 to 48. SO ... What I'm saying here is there was a side effect because my treatment was more efficient and every one who's taking piperine extract should be aware of that. And obviously, Bioperine is increasing bio availibility, and here's a proof it's working on a larger scale. As for a secondary benefit, I'm taking now half a pill of my treatment and it seems to be working properly. So just take care and be aware it could happen for you on molecules you're taking for your desease, not only vitamins are concerned here. Bioperine is doing exactly what it's designed for, perhaps too much better, that's why I rated 5 stars.

I take 1 tablet twice a day in the hopes of increasing the amount of nutrients absorbed by my system, but I'm not sure if it's helped after taking this for 4 months.

I didn't feel any increase in effect when I take this with my blood pressure meds. But that's not conclusive though, I would have to be more scientific about. Anyways ... research and clinical trials show a significant effect when taken with prescription meds ... so, please be forewarned when using this. The plus side is, if you already know that it /potentiates/ the effect of the drug you take, you can decrease its dosage while using BioPerine. Result? you save on your drug expenses! (You need first to know how it affects you though. And better -- consult with your MD). >>> To get more /Nuggets and Tips/ on products me and my family have actually bought and used... ...

I am using "0" empty capsules and fill them with ground black pepper instead. These are just too weak in potency in my opinion. Would have to take at least 4 with my Pregnenolone to feel them working.

Not sure about this supplement. I took it mostly for enhancing the absorption of other supplements, but I didn't noticed something different.
