Reliable product ; Reasonable cost

Wonderful

This is a great product when you are sleepy & need it to wake you up fast

I do not care for any type of coffee as others do, but I am able to feel caffeinated with one Vivarin — & since I am not a morning person, I love it!

I’m totally obsessed! No more coffee no more energy drinks. Just pure consistent crack head happy energy throughout the day. Helps me in class as a full time double major student and helps me stay motivated to get my life in order. I love it

I’ve used this product periodically for fifteen years because my dad would take it. The only thing I wish they’d change is some of the ingredients. Get rid of the yellow lake dye guys! It’s not good!

Very short experiation date. Maybe not manufacturer fault
