Muira Puama Benefits
Learning and Memory
Muira Puama appears to be a promising supplement for memory. One study compared Muira Puamaâ€™s effects on the memory performance of aged rats versus healthy adult rats in a step-down inhibitory avoidance test. Scientists use these types of tests to determine an animalâ€™s ability to learn.  The study showed that the memory-deficient aged rats performed just as well as the healthy adult rats after taking Muira Puama.  Muira Puama is may be able to supplement memory and learning via its interactions with serotonin receptors. 
Muira Puama is able to reduce the effects of stress and improve mood. This herb supplements the function of beta-adrenergic and dopamine receptors, which explains the boost in mood experienced after supplementation. [4,5]
