Review: Phenomenal - I used this to try to alleviate job stress (R&D at a startup company) and I was pretty amazed at the results. I had known about this since college but couldn't afford to take it in the dosage required to reduce cortisol levels. I still don't really want to make it a regular supplement due to its cost but I was at my wit's end trying to work out some technical issues we were having. I wasn't sleeping very long even though I had time to, which was making me feel even foggier at work. So I decided to give this a shot for a 10-day trial (6 gel-caps per day). The 10 days I took this was phenomenal. At the end of the first day I slept 8 hours which was an awesome improvement from 5-6 hours. Then the second day I slept 9 hours, Then 8.5, then 8 and finally leveling off at 7.5-8 hours for the remainder of the cycle. Because of the extra sleep I was getting (which really was just a normal amount for me) I could think more clearly and work through the technical issues we were having. I made so much progress that after I ran out, I just wasn't stressed and continued to sleep normally. It wasn't even so much that I was sleeping longer, but I was also sleeping much better, much deeper. I was literally lights out the whole night and had no trouble waking up in the morning. On the second night when I got 9 hours of sleep, my ear was numb because I hadn't moved at all. I was that exhausted. This supplement is definitely worth the money. I just purchased another to get through a work crunch and then travel home for the holidays. Not because my family is stressful (ok, a little) but I want to spend my mini-vacation getting very well rested and recharged. Overall, I find this to be a great supplement when I need some stress relief.
Review: Potential Boost & Mind Trigger Points! - I have recently been recommended these exact capsules from a friend who has been and is currently taking them. The reason being is simply to enhance the memory capabilities that one can exert from their own minds. Has it really done any of that? I can confidently say that it has. These capsules have worked well to strengthen my memory skills and allow me to remember or study college material for exams especially! Now it is solely based on the user if he/she wants to remember all the material for the rest of their lifetime by continuously studying and "practicing" the material otherwise your mind will begin to bury the information acquired. I have seen the results of these capsules work and they are simply great! I will mention the improvement should not be expected to make you a living and breathing calculating machine but it should smoothly expand the thoughts formed in your head and allow quick reaction time for particular "data retrieval" moments. Sleep, life stress, food consumed, headaches, and any other outside factors can impact the products performance as well. In other words, if you’re having a bad day with life problems swallowing your time up and your body is physically or mentally in pain; do not expect these capsules to save the day. They have helped me think better in rough situations, but it is up to the user to think of thoughts that keep any person in society ongoing without total meltdown. That is all I have to say about the product. I take about 2 a day although recommended dosage is 3. On an empty stomach, I can taste the after "burb" taste when drinking water with the capsule and waiting about 10 minutes. It has a strange taste but when I think of pig brain or whatever brain it contains, the smell of the burb somehow matches with it. It's nothing to be frightened about, just my experience! If one is concerned about this, simply intake the product with food. Even says to take with meals on the bottle but life is all about experiments involving trial and error and many times, success! Definitely would recommend this product to others but I am willing to keep trying new things also!

### ⭐⭐⭐⭐⭐ Excellent for Focus & Cognition; Works well with Dr. Best's Magnesium Bisglycinate
*by A***R on May 24, 2024*

I have noticed a distinct improvement in my ability to focus and cognitive performance ever since I began taking this product. It works well with Dr. Best's Magnesium Bisglycinate supplement. The latter complements this product in that better quality sleep enabled by Magnesium enhances the efficacy of this product. The capsule is the standard size and vegan and I did not experience any reflux or regurgitation after taking it. Phosphatidylserine (or phosphatidyl serine or just PS) is a fatty substance known as a phospholipid that is a component of cell membranes in plants and animals. In the brain, it plays a role in cell-to-cell communications. It is not an essential nutrient as it is naturally produced in the body, and it can be obtained from animal organs and from lecithin from soybeans, sunflower seeds, and other plant sources.
