Jeff, Mental clarity means so many different things! 
I go by the old remedy ofincreasing oxygen and nutrients to the brain and let 
it do the trick.
I take a daily combo of:
Gingko Biloba 24/6% extract 120 mg
Vinpocetina 30 mg
Bacopa Monnieri    200 mg
and Cayenne 50,000 HU 500 mg

This blend does the trick for me. 
Others need to take choline supplents like phosphatidyl chloline. Others need 
acetyl carnitine to increase the metabolic effciency of the neurons, etc.
Exercise to increase blood flow to the brain is essential. Upside down swing 
beds are excellent.
If the blood is too thick (hypercoagulability) take digestive enzymes in an 
empty stomach and /or Nattokinase enzymes.

Most common problems witth clarity, in our society, have to do with 
insufficient blood flow. All of the above will help. carful is taking blood 
thinners or bleed easiliy.

God luck

  I was wondering if anyone had something that's worked for them in helping 
with mental clarity. Increasing it actually.
