Does this nootropic stack look okay?

Research indicates that one must consistently take Alpha Brain for several weeks before there is a statistically significant effect on memory.

Different substances can expand and dilate the blood vessels feeding the brain. Blood supplies your brain with more oxygen, nutrients, and glucose (the primary energy source used by the brain during long periods of focus). By raising blood flow and oxygenation, this category of nootropics will immediately boost capacity for memory and focus. These are favored for more immediate, short-term boosts of energy and focus. 

There's growing body of clinicals behind therapeutics for cognitive diseases like Alpha Brain. The broad strategies of these therapeutics include removing toxin build up and neutralizing free radicals. There's interest from the nootropics community from using disease therapeutics as cognitive enhancers in healthy adults.

Certain classes of nootropics are associated with slowing down the neuron aging process. Over time, there is hope that this can significantly slow down signs of aging like loss of memory and even counter the development of cognitive disorders.
