Alpha Brain is a tablet offered as a dietary supplement by Onnit. They make many claims about its ability to help cognitive function:
The idea behind the Alpha Brain™ dietary supplement was to create the first ever fully balanced nootropic. Alpha GPC and Huperzia Serrata maximize acetylcholine levels while other ingredients assist in elevating dopamine and GABA levels, crucial components to remaining calm, focused, and mentally driven. Our vinpocetine assists in delivering oxygen and nutrients to the brain via increased blood flow, and the combination of neuro-specific antioxidants, led by our proprietary AC-11® helps to clear away mental fog and reduce free radical burden. The result experienced by many of our satisfied customers is an extraordinary combination of lucid dreams, mental drive, focus, memory, and mental acuity.
A buddy at the office just recently tried it, and is claiming it is real. It apparently is able to increase your memory recall and cognitive abilities, but I don't know if this is placebo or not.
I can't see how it is for real, but if it is, I wouldn't mind trying it.
