Sadly, I am not the sharpest knife in the drawer, I dont have these in depth, philosophical thoughts that others do, I dont understand most things as well as others, and I am a slow learner. For someone cursed with an overactive, enquiring mind, this is very frustrating. However, I have found some handy nutrients that actually helped me get through some difficult exams. Anyway enough of that, nobody reads this shit anyway, here are some brain nutrients: Omega 3,6,9 - these vital fats are essential for optimum brain function, as they form part of the structure of brain cell membranes. Make sure you take it in the optimum ratio, and ensure a high level of EPA and DHA Ginkgo Biloba - helps to increase blood flow to the brain, usually takes a few weeks to start working. Pantothenic acid - 100 -500mg Choline 500 -1000mg Phosphatidyl serine 30 - 100mg DMAE 100 - 500mg PABA (warning, this affects your mood, and could make you feel awesome,and its LEGAL) 50 -100 mg pyroglutamate 250 - 750mg synergy is the key, if you can find a supplement that contains these things in a capsule then take it, keep in mind that it will only be affective if you already eat healthily and supplement accordingly. Avoid coffee, as this affects the absorbtion of nutrients. So if you are studying, or just need a boost, try this advice, it can take some time to work, but when it does you will notice a MAJOR difference.
