I noticed the difference with these after this one day, more energy and better memory. After a while l got stressed, så l think these are a little to strong for me.

No effect

I haven't noticed any effects yet when taking this supplement, but perhaps it takes a while to kick in. See more reviews on my profile!

Not Sure

Posted by SherryB on Aug 23, 2012

I did not use this supplement long enough to really tell if it improved my mental clarity. For some reason, it increased my back pain and I had to stop taking it. I am super sensitive to anything that might increase or decrease my chronic inflammation. I am guessing that this had some undesired effect on my body chemistry. I have no major complaints though about the product other than personally it did not seem to agree with me. I wish I could give more feedback, but I wanted to be honest. Doctor's Best does make good products.

Hard to say if I notice anything from this - perhaps a slight improvement in concentration.
