Two times given substances with similar effect do it more effectively and I have proven - I wish I could re-order.

No results

Posted by iHerb Customer on May 18, 2017 | Verified Purchase

Although I heard good reviews about those, I myself didn't notice anything. After delivering a baby I've been experiencing some memory problems. Well, pill didn't help at all. A waste of money.

Thanks for your feedback!

Great cost effective product.

Awesome price and unmatched in quality

Thanks for your feedback!

Nice boost in memory and focus

Posted by iHerb Customer on May 03, 2017 | Verified Purchase

These give me a noticeable boost in focus, but really work well with improving my memory. I can read and understand (and remember) slabs of information while the effects last (around 2-3 hours per capsule. It's good to have a break between bottles, say 2-3 weeks. I actually find that my brain kind of retains the effects even after I've finished the bottle, you just need to keep up the momentum of using your mind.
