I've been using this stuff for a while. I notice more energy and believe that it has kept me from getting sick this year so far.

I have been using Zipfizz for many years and love it! It gives me a little boost in the morning without the sugar crash.

Love the product but HATE the packaging. Have to use a beer opener to get this open. And so difficult to get the plastic off. Will not buy again unless they change the packaging.

I'm never taking this crap again! Every time I do I can't sleep. I ruins my day, making me drag the next day, which makes me want to take it to get through the day. Repeat cycle. Never again.

My go to everyday!! I cannot live without this product

Great product, great price!!! Thank you Sam's Club!!!

This stuff works! Better than coffee. Grape is my favorite flavor.

This product in my opinion is nasty. Filled shaker up and it foamed all over. Will never purchase again.
