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.

Bioperine extract bevat 95% werkzame stof. Het is het vele malen sterker dan gewone zwarte peper. De meeste vitamines worden beter opgenomen als je ze samen met 10 Mg bioperine inneemt. Werkt zeer goed samen met curcuma. Opname tot wel 20 keer beter. Ik gebruik het dagelijks samen met mijn supplementen, veel worden er beter door opgenomen. Maximaal 2 per dag.

I'm sure this product is good, but now I buy other supplements that contain BioPerine, so no longer purchase this separately. But for anyone taking supplements that do not contain this, I would recommend it as it is supposed to enhance absorption.

this helps with absorption of other supplements.

When I first saw the little white tablets, I was dubious. But when I put one on my tongue, I could instantly taste the pepper. We take this together with the turmeric capsules we have, as turmeric is not easily absorbed in the absence of black pepper.

Taken 5 minutes before taking other supplements helps the body absorb and process more efficiently.
