Whenever I pick up any dietary product, I will always look for sugar content first. Not only 4D does not have any sugar, it is gluten and GMO free. It contains 0 calories which is a plus point for me since I am trying to loose weight. I tried 4D clean energy pack different time of the day to see the result and how it varies. I usually go to work very early in the morning so I use 1 pack right after my breakfast and it really helps me to focus. Then I tried before going to the gym and It helps me to maintain my energy level and fast recovery. It also helps me if I take 15-30 minutes before any activities and I do not feel any crash since it provides a very smooth and steady energy flow. Most products that are sugar free have after taste but 4D does not have any after taste.

Great product that not only tastes good but delivers good energy. It doesn't have the roller coaster effects of a typical energy supplement. You don't feel dehydrated like if you were to drink coffee. I usually take small sips throughout the whole day which keeps me energized.

Wonderful energy boost that lasts a long time. The taste isnt too bad and the effects are really quick to. I highly recommend this drink rather than diet pills or caffeine pills because you dont get that yucky, jittery feeling and crash. I have lyme disease and this really helps me wake up and be active when my body doesn't want to move.

I’ve tried a few energy drink mixes with supplemental vitamins,etc. over the past 2 years. I really liked how the 4D mix tasted. Nice fruit punch type flavor, not too sweet, and no after taste. These mixes did seem to provide a little more lift to my day than typical caffeine only mixes. A little better focus and a little better mood.

We used this product as an early morning wake-up (coffee substitute) and before workouts - worked very well for both. 16oz water plus about 8oz ice produced a very good taste that reminds us of a favorite from our youth - Flintstone vitamins.

I tried my first package of this drink mix today, and I wasn’t sure what to expect. I just added a pouch to a 16 ounce bottle of water and it seemed like a good mix. It tastes like fruit punch and is very pleasant to drink.

I love the ingredients in this drink mix. I really wanted to love it but it was a little too sweet for us. We only tried the fruit punch flavor so we will try other flavors. Increasing the amount of water to mix it with definitely helps so I would use 32 ounces of water for one packet. These are great for on the go use. We plan to pack them in our luggage for a boat trip in the Bahamas this summer. Did notice I had more energy throughout the day and for my intense workout. I think these will be great hydration. They do have 150 mgs of caffeine per pack. I would recommend this product to anyone wanting to increase energy and hydration. For a busy mom on the go these are great!

Love the overall convenience of the packets, and being able to pour this into a water bottle. My other go-to amino /energy supplement was sometimes difficult to break the tablet into a water bottle. Also love the range of nutrients included, including some caffeine. The biggest downside for me is the taste had a slight after-taste for me. The tropical punch flavor was strong, and sweet - but I still noticed a slight after taste, which is sometimes the downside of being able to easily get the amino acids and range of nutrients included in these types of supplements. Overall I would definitely recommend this as a great addition to your sports bag and good way for me to replenish after an hour or so of intense tennis play.

I am always on the lookout for an energy boost. After reading the info on the box, I was excited to give this a try. I was nervous when I open the packet as it had a noticeable vitamin smell. I mixed it in with a 16oz water. I was pleasantly surprised with the flavor; it did not have a vitamin taste like I was expecting and the sweetness was mild. I did feel a boost of energy after drinking this and did not experience flushing or palpitations that occur with some energy drinks.

Not normally a diet or energy guy drinking, tried something different this time wasn't a bad taste definitely was more energetic in the morning run getting the kids ready and headed to work seems like it did the trick to me
