This is my new preferred energy supplement. Bleep fiz always made me feel sick soon after drinking. With 4D there is no increase in HR or BP. Just a clean drink additive with a punch of energy needed to finish the day. Great flavor too, no bad after taste.

It definitely gives you an energy boost that lasts all day. Negatives are that it doesn't dissolve well and the sweetener used is overpowering in 16 oz. of water. It was tolerable in 24 oz. but has that same weird taste most energy drinks have. I drank it before doing several hours of yard work and my pulse rate stayed over 100 for hours after finishing so I wouldn't recommend it for people with heart or blood pressure issues. I didn't notice any increase in "mind clarity".

I tested this in the store and it was delicious. Some kind of orange flavor and bubbly. I purchased a box from the sales rep who I think receives some kind of commission, I don't know. The next morning I prepared with a bottle of water and added extra water and drank half when I just about wanted to throw up. I was nauseated for hours. First it was tropical punch and not bubbly like the sales rep gave. I can't wait to return to Sams

tried at Sam's Club bought a box ...I work at a cleaners sooo hot I usually would drink 2 Gatorades plus at least 4 to six water to stay hydrated When I drank drank a bottle water mixed with the 4D Clean Energy. WOW WHAT A DIFFERENCE..I only drank 2 more waters and felt great and even Cooler....I'll b buying more .
