I understand that when taken at night, before sleep, ashwaghanda will make you "strong as a horse".
I take Planetary Formulas in a tincture.
Sudo,
You've been doing your homework. Nice to see you've taken time to further educate yourself. I have a few comments.
Solgar sold out to Centrum a bout a year ago...they're off the list.
As for Optimum, I generally tend to move away from the brands that saturate the market with every possible supplement made in it's individual form and combinations. Much like NOW, Solaray, and Natures Sunshine. Those brands are marketed more towards the elder individuals on a fixed income believe it or not.

This is good if you have money.
