I do a lot of stuff on a daily basis, so i need to make sure i have enough coffee, energy drinks. I feel fatique throughout the days & energy drinks really gives me a boost. I don't drink them during sametime frame tho. I have tried a few different kinds of brands of energy drinks. They all have different kinds of benefits + ingredients. They all have different flavors. I will try just any flavor, that is if it's interesting to me. Energy drinks help me stay focused & alert. Not to mention lot of energy. I drink only 1 a day. I even tried the triple shot, bt omg that was too much for me & it gave me a headache..1st time trying Amin.o. Energy, that has Electrolyes + Hydration. 5 grams of amino acids, 100 mg of caffeine. 0 sugar & low calories.

I recently started getting back into exercising and decided to try this before my morning run. I drank it as instructed about 30 mins or so before my workout. The watermelon flavor was good and really refreshing. I didn’t feel anything initially but about 20-30 mins into my run I noticed I had a huge burst of energy. Most times I’m getting tired around that time but felt very energized and was able to workout and exercise for longer. It does have caffeine which I’m not a huge fan of since I am a coffee drinker. I didn’t drink coffee on the day I drank this drink as I didn’t want to be too wired. I did notice after the workout that I wasn’t as sore as I am usually. I do feel this drink helped with that. The drink is also so hydrating. I didn’t feel like I was even ... MoreI recently started getting back into exercising and decided to try this before my morning run.

This was a good experience for me and definitely would love to try the other flavors.

I normally stick to a very specific stack of supplements I use to support performance in the gym, but I was looking to branch out and try something new that I can drink during my workout instead of just water, and decided to give this a try. I try to stay away from sugar as much as possible so I really like the fact this is a sugar free drink that still is pretty good taste wise. Watermelon flavor is hard to do well, but this wasn't too bad. I use a preworkout that gives me a good boost to get started and combining with this during my workout I did notice there was a difference in my sustained energy level. I will continue to use this to ensure this effect is sustained and not a fluke, but so far so good. I like this drink and his has excellent nutrient that will ... MoreI normally stick to a very specific stack of supplements I use to support performance in the gym, but I was looking to branch out and try something new that I can drink during my workout instead of just water, and decided to give this a try.

This optimum nutrition is better then other drinks becuase of the amino acid ncluded and the electrolytes to keep you hydrated at cellular level during the day. Amino acids are important for neurotransmitters function. This seems to have 5 grams of every type which is good because most usually top glutamine as the highest when that is also found as glutamates in processed foods which we want to keep lower or avoid. The flavor tastes nice and light like a normal flavored sparkling water. I did not feel jittery with this ne drink but I drinks these very slowly during the day. One has to decide on f they like these for function and are okay with artificial flavors and so forth. Overall this is a tasteful drink and made me feel good with casual drinking throughout the ... MoreThis optimum nutrition is better then other drinks becuase of the amino acid ncluded and the electrolytes to keep you hydrated at cellular level during the day.

I like the overall idea of this product. It has seven amino acids which is a big plus. It has zero sugar and only 5 calories per serving which makes it good for a keto or low calorie diet. The 100mg of caffeine is from natural sources which I love because it doesn’t give me a jittery feeling like some energy products do. Basically it’s a good product for those who need a quick pick me up or for recovery after a workout. My only issue is the taste. The strawberry was just too overly sweet for me to enjoy. I had to drink it in small amounts because it was too much for me. I am open to trying other flavors and hope those will be better for my palette.
I so happened to give this a go while I'm in the peak of my marathon training. The week I decided to try this I had a 17 miles long run scheduled. Before a run like this you're not supposed to try anything new as there's a risk of discomfort. I'm happy to say I'm glad I tried this before my run. Not only is it made with great ingredients and amino acids, but it has the perfect amount of caffeine and vitamins required to perform like this. A drink like this can replace those gels or electrolyte mixes on runs like these. I'm excited to share I did not get nauseous or have an upset stomach, I felt amazing, no cramps, and was able to set a personal record for my run. I highly recommend this product to any athletes out there or anybody who wants a healthier lifestyle!
This is now my go-to drink for pre-workouts and or a good start to a busy morning! For starters, it has 100 mg of caffeine derived from tea leaves and or coffee beans. I don’t like too much caffeine and this is the perfect amount to get me going. It’s made with carbonated water that’s full of electrolytes like sodium, potassium and magnesium. It’s sugar free, and primarily sweetened with sucralose. Most importantly, each 12oz can has 5 grams of amino acids! There are 9 different flavors to choose from. I started with the Juicy Strawberry and also have tried the Orange Blast, and both taste really good! After a few weeks of use these have provided me the energy I need with no crash. They also keep me feeling hydrated and energized during my workouts! Whether you need ... MoreThis is now my go-to drink for pre-workouts and or a good start to a busy morning!

I picked this up for post workout recovery. Provides the electrolytes lost from sweating ensuring I won't be dehydrated. This can be used pre-work out as well or anytime you need a pick-me-up throughout the day. The 100mg caffeine from natural sources packs enough punch to give you that desired boost. I don't necessarily want caffeine before a workout so I opt for post workout instead. I've only tried the Mango Pineapple Limeade so far and it is pretty good. I like the sparkling effect especially after a run because it's so refreshing. I will say that these should be ice cold before enjoying them. I actually prefer mine over ice. I can't say that all the flavors stand out but the mango is definitely there. Big fan of zero grams of sugar and having no artificial ... MoreI picked this up for post workout recovery.
