Keeps me focused

Posted by Reviewer2823540 on Jul 03, 2010

I was looking for a supplement that help enhance mental function on a deeper level than a cup of coffee. After taking this supplement I am able to focus for longer periods of time and retain information better. Could be that something leaked into the tap water I am drinking and that zapped my brain to work better, but I'm certain this supplement is helping some as well.

I have used this product for more than a month now and only half of the suggested dosis for now (planning to increase it). I have used other supplements but with very different results. With Neuro Optimizer I have noticed a big difference in my ability to focus and concentrate in spite of how tired I can be which is usually the case due to my daily activities. Also, it allows me to be more alert and less confused. I take it every day but once I stopped it for few days and immediately noticed the difference. Highly recommended.

a serious weapon in the battle against brain fog

Posted by alloriginal on Aug 30, 2013

a couple of years ago I was really starting to notice the signs of mental aging. Nothing dramatic, just more and more of those dreaded senior moments that we all fear. I decided to do something about it...my journey led me to Jarrow Neuro Optimizer. What a difference! It was a subtle and gradual change; within a month I felt like a new person. I'm now much sharper mentally, more verbally fluent, and a lot more confident than I was. This has changed my life and ROCKED MY WORLD! Important to note that I use other products as well, and attribute the changes to them as well (vinpocetine, coenzyme b complex, phenylalanine, Sam-e, high dha fish oil, dmae). Try this...it will make a huge difference in your life! Click my reveiwer name for reviews of other helpful products.

Cognitive functions, fibromyalgia, chronic fatigue syndrome

Fast improvement. Helps with brain fog, focus, recall etc. Less tired. I take it with "Neurozyme" for added benefits. Update: After a few months of taking "Neuro optimizer" I can tell the difference in brain function. Slowly but steadily my recall, memory, learning abilities etc. have become like before I got this decline in cognitive functions due to multiple diseases. The formula is also good for the heart if that is an issue! I combine "Neuro optimizer" with "Neurozyme", "alpha gpc" by jarrow formulas and finally "PS" also by jarrow formulas. By taking all of these products I have a complete protection from cognitive decline. If I stop taking any of these products for some time, I notice a worsening of symptoms.

I can think clearly again on day 1!!!

Wow!!! Amazed at how fast these work. Based on reviews I took 2 tablets and find this works well for me. I now have a good sense of well being, I feel like getting up and doing things, I don't feel confused as before and don't forget things right away like I did before. I'm hoping this improves My long term memory as well. So glad the fatigue is gone!!!

Recommend it

I took this for my anxiety / depression and I observed an improvement in my mood, and I was not so nervous all the time. This is a great natural alternative to anti-depressants.
