These nutrients naturally complement each other: GPC reaches very high concentrations inside cells; PS is a building block for cell membranes that generate the brain's energy and electricity. Numerous double-blind trials catalog the benefits of GPC and PS for people of all ages.

iHerb Customer Reviews
this is one of the best supplements I've ever found. I would gladly pay double what Iherb is charging. Since using twice per day (several months now) I'm definitely sharper mentally. The fog of depression has lifted and I'm a lot more confident and verbal than I was. It took about two weeks to feel the effects, and it was a subtle and gradual change. I used in combination with a vinpocetine supplement, and I think the effects are attributable to both. UPDATE: I ran out of vinpocetine, and within a few days could tell I was going downhill. Please try this product (two per day at first, increasing to 3 or 4 over two weeks) along with a quality vinpocetine supplement, especially if you're over 40. I want everyone to feel as good as I do now! I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.
After reading up on these two supplements, I have been using this for several months. I've noticed improved concentration, memory, reaction time, muscle tone and have lost weight. Love it!
clareza mental com uma só

no incio do uso meu cerebro parecia rejeitar dava uma sensaçao de esforço mental e parecia nao ajudar muito, mas depois a clareza mental e foco melhoram sim, mas nao tanto a memoria digamos que, de 0 a 5, clareza: 4, foco:3.8, memoria: 2.8 ....mas resumindo o produto é bom! poderia ter um com vinpocetine, bacopa e huperzina A ai seria o TOP!
These pills made me dumb!
Posted by CurbAnxiety on Mar 22, 2016
It's interesting to notice how differently these brain enhancers affect to different people. For me they were everything else than brain enhancers! I became totally dumb after taking these. The longer I took them, the more foggy my brain was and the less I could think clearly. It was almost impossible to work and that really affected also to the quality of my work, I'm ashamed of that! Moreover, an hour or two after taking these pills I became so tired that I had to take a nap, there was no other way out. I took the pills two weeks, one pill every morning and then I simply couldn't stand anymore. One note: as I follow ketogenic diet my brains mostly use ketones as energy, not glucose like normally. I wonder if this had anything to do with the bad results. Anyway, I'm happy with my brains and don't need this product, just wanted to try out if it would have had any positive effect. I'm happy for those people who have found help from this product, I'm just not one of them.
A bit unsure
Posted by Reviewer2635763 on Mar 03, 2016
I'm not sure if it's just me. The first day I took it, I developed indigestion and bloating. I have IBS, so it could be unrelated to consuming this product. However, I do note something - I have a poor sense of direction but this week, I could guide a coworker to a location using a route I've never used. I could put their relative locations together and direct her to the place she wanted to go. That could only be explained by this supplement. I think one should not expect to have this sudden lightbulb moment when taking this supplement. Rather, it manifests in small, pleasantly surprising ways.

eh im not sure if its doing anything
Posted by 4613259693704334636 on Jun 22, 2015
I starting taking this supplement since I'm studying a university math course and I was really struggling at the beginning of the course. I've only been taking it for a couple of weeks, but I can feel a bit more focused and am able to solve more complex problems. My mind seems to "click" faster and I am able to solve the more complex problems with more focused thinking. As I focus on the problem, the solution suddenly comes to me now. It almost feels like my brain does a faster scan of the hard drive to connect the dots, and it suddenly clicks. The first couple of days of taking this gave me pretty annoying headaches that lasted almost all day from the time I took the pills. The headaches almost caused me to stop taking it, but I don't get them anymore. I noticed now that two pills in the morning work best and I sometimes take a third around lunch if I'm studying a lot and am getting fatigued. But I find that I can sometimes get a bit of a brain fog if I take the third pill. Overall, I do feel a bit sharper. I've also found on days that I take this, when also taking L-Theanine before bed, I end up having very vivid and lucid dreams. Some of them are very realistic and can get freaky. But I would certainly recommend experimenting with this and see if it works for you.
