Noticeable energy boost
I've been taking these for about two months and my afternoon slump is gone. Easy to swallow and no aftertaste.

Great value, complete formula
The nutrient list is more complete than what I was buying before, and the price is fair. Will reorder.

Works well for me
Gentle on my stomach when taken with food. I'd love a slightly smaller tablet, but no complaints otherwise.
