If you are run down, have one. Drink within 5 minutes of mixing for the max benefits of the B12. Wouldn't recommend drinking one too close to bedtime though. Flavor of grape soda is great - You can make it as weak/watered down or strong/less water mixed to your liking. They come in a waterproof, snapped capsule so very portable. Easily add to your bottled water before a workout or afternoon work pick-up.

I recently learned of Zipfizz while shopping at my local Sam's Club. Fortunately, that day, there was a sales rep for it there! I was able to try several different flavors and after much deliberation, went with GRAPE! It is awesome! The flavor is great, the energy boost is fantastic (no jitters involved) and the health benefit of getting all those vitamins + electrolytes is AWESOME! I will definitely be getting more of this!

Has helped raise vit B6 & B12 levels for a family member. Aunt enjoys it made with lemon flavored Crystal Light - beats drinking a pop. ;-)

Disappointed this item was removed from the local stores shelves. Would like to have product shipped to my local Sam’s Club for pickup versus going to my office. My home is not an option to send packages.

After visiting 3 Sam's, I decided to order on line. I received notice when the order was received and when it was shipped. Arrived in a timely manner -- just before I ran out!

This stuff is great. The orange soda flavor is the best I've had. I've tried the citrus, and it is like grapefruit, and doesn't taste bad. Now I am craving that taste to wake me up in the morning. I've had the pink one and found it to be too sour for my tastes. The Grape is like the Orange and I drink it just like the Orange. I tend to stick with the orange since I know it tastes great. I usually end up drinking 2 in the morning, and sometimes a 3rd in the afternoon. Whenever I need a "pick-me-up" I can count on this stuff.

I love these. I almost don't want to tell anyone because I would hate if they were sold out! Sometimes I get the variety flavor pack but the purple is my favorite so I always order a pack of just those, too! I quit diet coke and now drink one of these per day. Must buy!

This product is terrific! Also, Sam's Club online has a very competitive price on it--that is why I buy it here. Just wish the Sam's Club stores in my area (NE TN / SW VA) would carry it instore!!! This product gives energy with a sense of wellbeing, without that all-too-common inevitable crash from mere caffeine-only products. Provides a powerful dose of vitalizing B-12! I simply love this product! If I could find it at a better price, I would take one - two servings a day! For now, I reserve our tubes for high-stress / intensive-demand items on my schedule. Still, for energy supplements, I've found nothing better so far than this product, and ABSOLUTELY no other place where it is more affordable than at Sam's Club.com!!!

This product is one of my favorites. I purchase it frequently. Lately, I have not been happy. This is the third time i receive an empty tubes within the box. And a few times now, there have been tubes that are not sealed. I have had to dispose of them. Waste of money. Not happy.

I remember the trial phase when they gave samples in the store. Crushed ice and GRAP zipfizz. I was thrilled with it then and have been buying it since. This is the Mrs. and my husband accuses me of being ADDICTED. I remember that same grape flavor and bite when I was a kid in the individual grape gum. They didn't wrap it, it was a large grape ball, and all tossed into a wooden bin. AWESOME! My only complaint is availability now. They only carry the multi-packs and I don't like certain flavors NO MATTER HOW much cheaper! My last online order was a week out in getting here to only get sent a flavor other than GRAPE and I had to return it. Waiting AGAIN for a week!
