I took the product first thing in the morning before breakfast, as suggested, and had zero issues with nausea or other issues. I noticed a better ability to focus and stay focused whatever task or project was at hand.

Excellent nootropic energy, but definitely remove all the Acetyl-L-Carnitine! It causes lightheadedness, dizziness, etc and doesn't help energy/focus at all. Many Reddit posts collaborate! Formula is absolutely perfect otherwise.

Provides a very nice edge. Definitely a smooth and precise push. I like it, but must be careful with additional caffeine. If you are a coffee drinker, you might wish to reduce or eliminate coffee when taking. I add a bit of theanine with any additional coffee. But highly recommend you try Focus and find where it fits in your program. Nice product. Especially like how the taurine and tyrosine combine.

The pills did not have a bad after taste to me, however 5 pills is a lot to take in at one time. Unfortunately I did not feel any different after taking them for 5 days.
