CDP Choline as recommended by a physician for the past year, has helped improve my mental function. Increased clarity and memory recall ability. For me, there is a distinct difference when I am not supplementing with CDP Choline. As a two time stroke survior, the discovery of this product, has been a "brain blessing".

To be honest I didn't even think that this stuff was working until I stopped taking it. I love the alertness and my ability to focus in easily, which has helped me have more productive days. In terms of supplements for productivity Citicoline may be one of the best products that I have used.

Achieving an advanced degree in a tier one university is hard work, especially if you're over 50! This product has helped erase the brain fog, improved my memory, and done wonders for my focus. My cognitive thinking is so much better! It makes being an honors student come so much easier; I'm very thankful!

Did lot of research on Alpha GPC, CDP Choline, Bitartarate version etc, as also on several different Choline products and brands available on Amazon and elsewhere. Most products had fillers, chemicals, gelatin etc, or were costly or ineffective. This Citicholine product from Zazzee Naturals, is the cleanest of all Choline products on Amazon! Veggie capsules, mostly organic items and clean and potent Choline. CDP Choline is more effective than the Bitartarate version. The product gives a nice, clean buzz, and I am already seeing an improvement in mental clarity and focus in couple weeks of use, and dd not see this kind of effectiveness on any other supplement I have tried for a similar objective. To cap it all, their price is absolutely unbeatable, as you get almost double the amount of capsule/mg as compared to other brands, while still packing a potent punch, and in a clean, Organic ingredient/Veggie capsules! I recommend this product highly!

I have had my dad on several brands of citicoline, and this one seems to be the most effective thus far. My 90-year-old dad has been on this product for about 2-3 weeks, and I have noticed a difference in his focus, memory, and energy. He does not repeat himself as much and he seems to retain what I tell him. I am very optimistic and grateful for this product.
