Hi ElexaAnn!

Yes, there are some outstanding all-natural supplements that help increase and optimize mental acuity and memory.  I love the Focus Excel or the Xtend-Life Neuro Natural Memory.

And yes, you are correct about diminishing neuron functioning as you age.  Most of the "mapping" that occurs in our brains happens when we reach 6+ months of age and up to about the age of 12.

Live Well, Be Healthy - ElexaAnn!

BTW:  I love to hear about the benefits people experience with these, so if you try one can you please respond back to me?
