CELSIUS Fitness Drink 9-Flavor Variety Pack, Zero Sugar, Slim Can 12 Fl Oz (Pack of 12)

I suffer from chronic fatigue syndrome and have to take medication daily to help combat it, but it still doesn't work completely. Getting going in the morning, staying focused, energized, and physically motivated has been a struggle for me since childhood, and genetically I metabolize caffeine at much faster rate than what is considered to be average or normal (I had DNA genome testing done). This means the amount of caffeine I need to consume in order to benefit from its effects is much greater, and the duration of its effects is considerably shorter. I end up having to drink caffeinated beverages all day long just to stay awake, but it does very little in regards to keeping me from feeling sleepy or physically exhausted. Unfortunately this has also led to weight gain because I'm not as active as I'd like to be.I've tried every energy drink, every caffeinated gum, every powder, every energy pill. They either don't work well enough, are too sweet, make me feel nauseous or shaky rather than energized, cause headaches or sugar crashes and leave me feeling worse.I ordered a case of Celsius not knowing what to expect, but willing to give it a go. The fact that it is sugar free, aspartame free, free of artificial preservatives, high fructose corn syrup, and free from artificial coloring and flavors was the high selling point for me. The burning an extra 100 calories claim was just a bonus, but also intriguing. I hoped that it wouldn't taste awful. I'm very happy to say that not only does it work at keeping me energized and not just awake, it tastes great!My favorite are the two non-carbonated flavors, but the carbonated flavors aren't horrible though, even the cola which I was dubious about.Just ONE of these in the morning has completely replaced my need to drink copious amounts of coffee, tea, or soda throughout the day. Only one day did I have Celsius and coffee both. It makes me feel awake, focused, and most of all I get things DONE! It doesn't make me feel nauseous, shaky, give me headaches or cause any kind of crash either!I'm am SO glad I tried this! This is a total game changer for me! I am now completely out and ordered another case.Word of advice: if you drink it too late in the day you're gonna be up all night. The first time I tried it I drank it at around 7pm because I was falling asleep and needed to cook dinner. I ended up not being able to sleep until about 4 am. Also, if you're sensitive to caffeine I'd drink half and wait to see how it affects you before drinking the other half. My friend tried one when visiting because I was raving about it and it made him really shaky and anxious before he even finished it.I'm a complete convert and now I don't think I could go a day without having one in the morning.Highly recommend trying! Not only does it work, it's not full of nasty chemicals. Who could ask for anything more?**Update 12/6/16**I still drink one of these a day, sometimes two depending on what I'm doing and how much energy I need. I basically only drink the Cola and the Raspberry Acai flavors at this point.I tried the Watermelon recently and I don't like it at all. It has that chemical watermelon taste to it that watermelon gum has. Gah! I don't recommend that one. It's the ONLY flavor I've tried that I flat out dislike. It's way too sweet. I still have the case in my pantry. If I'm out of my regular flavors I will down one quickly before it loses any of its coldness. It's honestly the only way a I can get it down, bleh!Avoid!Despite the nastiness of the Watermelon, Celsius is still part of my daily routine. It's still the only drink to have the effects I'm looking for in an energy drink.I've even gotten a friend hooked and she now orders them and drinks them daily as well.My mom has MS and has a lot of lethargy because of it. She was drinking a few of the leading brands of energy drinks, and all the chemicals in them worried me, especially with how much of them she was drinking. I recommended that she try out Celsius, and now she drinks one a day and no longer needs to drink the other brands, and she is able to function much better all around. She swears by them and tells me she isn't getting headaches anymore, doesn't get jittery and her stamina for physical activity has improved greatly.

Tastes great and truly enjoy.

This stuff is pretty great! I've typically been drinking a can each morning before my run and I have burned more calories from the energy it gives me than I was burning previous to drinking these. That's definitely what they mean by "burn an extra 100 calories". Simply drinking Celsius will not shed any pounds; it is meant to be a supplement to aid in calorie burning.Although Celsius seems to be an excellent source of energy, I learned the hard way not to drink it at night. I was so excited to receive them that as soon as they arrived at 7pm, I immediately chugged an entire can. While my run was awesome and filled with energy that night, I finished the run and spotlessly cleaned every surface in my apartment, vaccumed every inch of carpet, scrubbed all of my tile, and pointlessly did laundry and other various chores that were definitely not necessary. Having all of that energy was great until it was suddenly 3am and I was unable to fall asleep to wake up at 6am for work! Big mistake.The flavors aren't too bad, either:Raspberry Acai Green Tea - This one is, by far, my favorite. Perhaps it's just because I love tea, but the flavor is nice and refreshing. It almost tastes like a low calorie snapple.Sparkling Orange - While I'm not a fan of carbonation, this flavor wasn't bad at all. To me, it tasted like diet orange soda.Sparkling Wild Berry - Another carbonated flavor that isn't too bad if you like that kind of thing. I thought it tasted like a fruity soda.Cola - This tastes EXACTLY like diet Pepsi.Green Tea Peach Mango - This flavor was also quite good. You can definitely taste the fruit in it, which is comforting and yummy.So basically, if you're looking to boost the energy in your workouts, I would suggest Celsius. It's a million times better than any other energy drink on the market and it's much better for your health. Try it out!

First and foremost, the peach/mango tea has to be the best tasting energy drink I've ever had in my life - there should be a wider variety of non-carbonated energy drinks out there. I'd drink it just for the flavor, if this wasn't also one of the strongest energy drinks in the market. If you really need to pull a productive all-nighter, this is the best you can get for the price. It will keep you alert, and two in a row will probably get you hyper enough to hinder your concentration.The other flavors are also pretty good - sparkling cola sure tastes better than Pepsi. I'll always keep a stock for this for when I'm too tired but really need to work anyway.Only con: they misadvertise this product as being 'healthy. Thanks to the sweetener and they use and the ridiculous amounts of stimulants this thing has, I think that is the one attribute this product def. does NOT have.

First off flavor wise they were all pretty tasty and some might be tastier than others depending on your taste buds.Perfect type of energy boost given by caffeine and other ingredients and in the time I have taken Celsius I can say I haven’t experienced any crash unlike some other “energy” type drinks. Celsius is a favorite of my wife’s especially if she is heading to the gym as she says it increases her sweating a little. Now the only complaint I have about Celsius is the type of B12 they use in their product. I wish they used methylcobalamin instead of cyanocobalamin form of b12 as methylcobalamin is a natural form compared the the synthetic for of cyanocobalamin. That would be my only negative.
