Be Smarter. Think Clearer. Improve Memory. Be More Present.

Mark Alan EffingerAugust 3, 2008

Pyroglutamic Acid is, in some ways, a miracle amino acid. As the founder and CEO of a brainstorming software firm, I am expected to have something "oin the ball, when it comes to how to optimize the brain. L-Pyroglutamic Acid is one of the key ingredients. I work sometimes 20 hour days, back-to-back. The stress this puts on your choline stores in the brain is significant. L-Pyroglutamic Acid is one of the major amino acids to restore that critical neurochemical, and put you back on track. I take 2000-3000 mgs immediately before bed. Wake up feeling great, and VERY sharp and crystal-clear. I've tried 5 different brands, and Source Naturals L-Pyroglutamic Acid 1000mg - 120 - Tablet seems to provide the greatest overall benefit. Mark Alan Effinger RichContent.com ThoughtOffice.com --------------------------- UPDATE: I've been addressing a bit of "midnight anxiety" aka Restless Legs Syndrome (why do they have to label such things?) This is caused by a lack of Dopamine in the brain from either: 1) Too many stimulants 2) Burnout (too much stress) 3) Not enough exercise 4) Aging I'm extremely healthy. Exercise daily (lift weights, run and Trikke). I regulate stimulants, and don't take them late in the day. OK, so I'm edging-up to 50 pretty quickly. But I look and feel 38-ish. So I don't think age is really the deal. Then I looked deeper, and realized that I had dropped my use of Source Naturals L-Pyroglutamic Acid 1000mg, 120 Tablets . Started back up, and PRESTO! Feeling great. Also, in terms of deeper sleep and cognitive enhancement: This really does make a pronounced difference over 2-3 days. Finally: I'm using Brainstorming and Creativity Software - Thoughtoffice Innovation Suite Mac OSX - Windows XP-7 to help keep my lateral, creative and inspirational thinking rock-solid. For you writers, I can highly recommend Novel Writing Software - ThoughtOffice Muse Creative Writing Software Suite Mac OSX - Windows XP-7 . And if you're running a company or three (like moi), here's the Killer App: Business Productivity Software - ThoughtOffice CEO Software Suite Mac OSX - Windows XP-7 Finally: If want to have some fun, I have had years of "play" using the concepts in The Ideafisher: How to Land That Big Idea-And Other Secrets of Creativity in Business . Great for work and... well... everything. Read more

Seems to benefit mental endurance

Not My Real NameAugust 31, 2025

I usually take this when I'm feeling run down and like I need something to help me push through. The effect isn't dramatic, but pronounced enough that I'm confident it's not just placebo. Creatine is actually better for this purpose, but I think takes longer to have an effect and you quickly build up a tolerance to it. And when you stop taking it, you'll probably find you need more sleep than usual. Read more

Did Not Work For Me BUT ..................

CalebJanuary 5, 2015

Recently I started using a Ginkoba based focus supplement because of part time school with a full time job and it worked well. Once done I decided to try something different and after some research I stumbled on this. I ordered a bottle and have not noticed any difference whatsoever. Now I am not saying that it does not work or is a placebo because the same Ginkoba supplement that work for me some people say that they don’t work for them at all. My best guess as to why this did not work for me could be that maybe my body produces more than enough of this acid. Now I know researching and purchasing a focus supplement on Amazon is so tiring with all the bogus reviews and uneducated discussions on the subject. But you just got to keep trying until you find that right supplement to assist you. Read more

Brain "working" again!

Brandon LewisNovember 24, 2014

My son was diagnosed with ADHD at a very young age and had been on Vyvanse for years. He suffered a traumatic brain injury three years ago which resulted in unbelievably awful neurological problems and his inability to take Vyvanse. Luckily, we found a medical doctor who believes in homeopathic supplements and specializes in cognitive function. It has been a long road back to normalcy, but pyroglutamic acid is the supplement he says has helped his ADHD issues the most. He didn't even know he was taking it as I simply included it in his evening pack of supplements that he takes to repair the damage from his brain injury. The next day he got in the car after school and said he had a great day because his brain was finally "working" meaning he could retrieve information from his short term memory and he said he could think a lot faster. I was amazed. It seems to be non-stimulating too which is a real bonus in his case. He takes 1/4 tablet four times a day. Read more
