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 is basically 95% extracted piperine from black pepper. Different studies have shown that bioperine can increase nutrient absorption by increasing our body’s thermogensis. However, the studies limit the test nutrients to vitamins, minerals, a few herbs, a few antioxidant and some amino acids so it’s hard to tell if it works for other untested supplements (they only show those that works, not those which didn’t). As suming that it works with all nutrients and herbs, this will be a good product to add especially if you are taking a lot of different supplements. You get more nutrients without increasing dosage or you can save by reducing the dosage since you are absorbing. The tablets are round, very small and easy to swallow. However, this product also contains a lot of junk like calcium (probably from the dibasic calcium phosphate since I am not sure if it is even absorbable and flow agents like microcrystalline cellulose or magnesium stearate which actually inhibits nutrient absorption! Pricewise, this is very cheap and can easily last 2 months (2 tablets daily). Unfortunately, this is also the only product with Bioperine as standalone. Personally, it feels like it does helps increase absorption though not as much as expected. Check out my page for more reviews!

These little pills are not coated, so don't leave them in your mouth too long before swallowing or you'll know how peppery they are! I like the dosage, the brand, and how small they are. I take a lot of pills at once but when this one is in the pile I make sure I'm fast.

So far excellent. I really feel the difference including this along with my daily vitamin supplements.

Since I'´m taking quite a few supplements I can't honestly say that I feel the effect from BioPerine distinctively. However, I know that the bio availbility is enhanced, and reading the label etc here, I´m confident that this offering from Source Naturals must be one of the very best. Recommended!

Do the job, but it's better to take it with food so you willn't have heartburn.
