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.

I received this last week and was surprised how well it mixes in water - many times these products don’t completely dissolve. Not this one! Also, the flavor is very good and does not have a bitter aftertaste like comparable products.

My wife drinks vitamin and energy drink packets daily. She was vey impressed with the taste and the quality of this product. I have tried these and they do have a pleasing flavour. We will be buying more.

Great drink! Use it everyday.

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.

A good energy drink. Dissolves quickly, a little on the sweet side. A nice pickme up drink for the afternoon. I would recommend this product to anyone who needs a quick pick me up drink. Zero calories.

This is a nice little drink add in. The fruit punch flavor tastes good but is a little too sweet for me to use as suggested (mixed with 16-24oz of water). I use half the amount per the same amount of water and it works well. The powder itself has a slight carboard smell to it but once water is added it disappears and you dont taste it. I've been using it about 30 minutes prior to my workout as suggested and I haven't noticed any huge difference in energy levels though I also didn't get the jitters or anxious from it which I prefer. I love that it is dairy free, gluten free and has zero calories! Great way to add some flavor, vitamins and amino acids to your water.

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.

4D Amino Vitamin Energy Supplement is a convenient option for healthy adults who need a quick boost of energy and hydration. It's easy to use and great for on-the-go support. However, it's not the best choice for seniors, medically complex individuals, or for daily long-term use without proper guidance.
