2 or 3 of these every day are a necessity for those of us over 40. I have a super challenging computer job at the world's largest retailer. I have to be sharp at all times, so these are a godsend. I'm 60, by the way, and outperform all of my younger coworkers. 💪

Great drug like n for me! I bought myself because I have hard work, I work with a large amount of data. I liked this drug! The head is clearer, there is no fog, they feel more focused. There were no side effects! He took two capsules a day while eating, this is a dosage according to the instructions. It is recommended to take until 16.00, since there is a invigorating effect. I can recommend everyone to receive, especially during periods of high mental load

Doctors Best is become our favorite family brand! The product is a supplement for improving health, immunity, quality of life, well-being and mood. I bought it out of curiosity after reading "Vitamin" in the title of the search results. It filled some essential needs I had so far: energy boost and eliminated fatigue due to long flights and stress.

The packaging quality of this product is very good. The ingredients of this product are very good and it has an excellent effect on improving the brain after consumption. The pills are the right size and easy to swallow. The taste is good and I would like to purchase again next time.

I have tried so many supplements that I lost count and faith. I used to have brain fog and my memory was suffering. I was tired and not interested in doing anything. I made two changes - started to get enough sleep and this supplement. When I miss one of these I can notice a change. It works really well.

And after all, I really began to think better! Only sometimes a little drowsing the head, the outflow of blood is probably broken. I think many need to pay attention to this so as not to bring themselves to a stroke. And I’m going to the osteopath to fix and continue to drink the ) supplement

I got straight A's and felt amazing while taking this during my studies so... However, I do feel it's better to buy these ingredients independently so you can adjust the dosing and take only one of them, the one more appropriate to your goals (or both when desired).

Actually Seems to work! and improve memory capability, focusing ability and learning, and I suppose other cognitive functions. Sometimes I take 2, depending on the task. Sometimes I prefer not to use it at all, depending on the day's tasks. I am only on my first bottle, and still experimenting. Will update.

Doctors Best Natural Brain Enhancers have high quality ingredients - Choline, (GPC) and PS, (PhospholipidSerine) which have shown in research studies to aid brain health including aiding memory and learning. I have taken these supplements for over 3 years in a variety of stacks, and find that my memory and brain function has benefited from these and accompanying supplements well into my retirement years.

Such a great combination of ingredients, happy to have found this do I don’t have to buy several products. Alpha GPC is the star but I’m super happy to have the rest of the support ingredients in the formulation. Has really helped to clear up brain fog, highly recommend.
