To this day, they are still continuing to work on bringing you great products that can help you meet and achieve your fitness goals. They are one of the big players when it comes to pre-workouts and protein powders. They are a brand that customers have grown to know and trust.


Something that a lot of customers can appreciate about this product is that it comes in a variety of different flavors. You can pick and choose your favorites and avoid the ones you don't love. There are more than just many great flavors to choose from, though. You can also pick from a variety of forms, as well. You have the ability to purchase this product in a powder, individual serving pack, or pre-mixed liquid. Each one of these choices comes with its set of flavor choices, although some are very similar to one another.

Something to note is that the fruit fusion and fruit punch have a very similar taste to them; there is barely any difference. Additionally, the orange cooler and orange blast are almost the same, as well.

Overall, customers love that there are so many great flavors and forms that they can choose from when ordering this product.


Since there are many different flavors of this product, it can be expected that there are going t be mixed reviews on the tastes. For the most part, however, customers enjoy the taste of this product as a whole. After all, why would you want to add something to your diet that isn't tasty?

There are a few flavors that some consumers have found to be overly sweet, including the watermelon. However, this doesn't hold true for all of the flavors. Additionally, there are a couple of them that will leave a weak aftertaste in your mouth. If you do come across a flavor that leaves a bad taste in your mouth, it is effortless to get rid of, take a drink of water, and you will be good to do.

For the most part, reviewers stated that the tastes are reasonably close to the flavor they represent. So, if you are choosing one of the orange flavors, you can expect it actually to taste like orange. That isn't true with many flavored drinks, but at least with the Optimum Nutrition Amino Energy, you will know what you are getting.

It seems to be a matter of experimenting with the different flavors until you find one, or more, that you love. Sometimes consumers prefer having a variety of tastes on hand so they can change things up as they see fit. It can be boring consuming the same thing day after day, so having the ability to change is always helpful.


Sometimes consistency can be a sore subject when you are looking at energy drinks and powdered supplements. There are a lot of products out there that don't mix well and leave part of the powder inside of the shaker bottle, meaning you aren't consuming a full serving. Thankfully, this isn't a problem that customers will have to worry about when it comes to the Optimum Nutrition Amino Energy.

Since there are different types of this product, they are going to have different consistencies. First, you can choose a pre-mixed drink. You have nothing to worry about with this version. There is no mixing and, therefore, no gritty texture and nothing left behind.

If you opt for the powder so you can mix your own drink, you still won't have too many problems. Customers have stated that the powder dissolves and mixes rather well. There is no need to down a gritty and crunch drink. Additionally, since it dissolves well, you won't have to worry about leaving your supplement behind stuck to the side of your shaker bottle.

In a world full of protein powders that leave a bad feeling in your mouth, this one won't.


Since there are a variety of flavors to choose from, you can expect that there will be a different list of ingredients for each one. The problem with a lot of supplements, including this drink, is that they use propriety blends. Because of combinations like this, it is harder to know precisely what and how much of any given item you are actually receiving. One of the saving graces of this particular product is that it is from a well-trusted brand, which makes this just a little more acceptable in the eyes of some customers.

The Optimum Nutrition Amino Energy uses two different proprietary blends in their formula. First, you will find their Amino Acid Blend which includes L-Arginine, Taurine, L-Leucine, Citrulline, Beta-Alanine, L-Valine, L-Isoleucine, L-Glutamine, L-Tyrosine, L-Lysine, L-Histidine, L-Methionine, L-Theanine, and L-Phenylalanine. Those might sound like big names, and they are hard to pronounce, which can turn some consumers away. However, this is actually a great Amino Acid blend that will assist in accelerating muscle recovery.

Additionally, this product features an energy blend to give your body clean energy to fuel your workouts. You will find components like caffeine, green tea extract, and green coffee extract.

In addition to these blends, there are a few other ingredients in the product. These are there to distinguish the different flavors, tastes, and coloring.


The Optimum Nutrition Amino Energy does contain a small amount of caffeine. For most people consuming the small amounts of caffeine work just fine for them. Each serving contains 100 mg, which is less than an average cup of coffee. This is nice for those who have sensitivities to caffeine or who try to limit their intake. You can always use a little less of the powder if you want to reduce the amount you are consuming.

On the other hand, if you are used to far more caffeine and you need a little more to get you going, you can always opt for taking a little more. It's easy enough to slightly increase your serving size since the ingredients used in this product are not very potent.

One of the most significant benefits of this drink and its low calorie count is that there are fewer risks of adverse reactions. You shouldn't experience a crash at the end of the day or the jitters.


If you are trying to monitor your sugar intake and keep your consumption low, then you are in luck. The Optimum Nutrition Amino Energy doesn't use additional sugar to help sweeten their drinks. Instead, they use the artificial sweetener sucralose rather than add sugar.

If you experience one of the flavors that taste overly sweet, it is the sucralose that is to blame. Additionally, this is the reason some of the flavors will leave a poor aftertaste in your mouth.


Many times when people consume products with more than normal caffeine counts, they can experience a crash after a while. This typically happens at the end of your workout when you are left feeling empty. You are completely drained of your energy. This can ruin your whole day if you are working out in the morning and crash afterward.

However, when it comes to this product, there are not real customer reports of a crash. This is probably thanks to the fact that there isn't an excessive amount of caffeine in the supplement. Yes, there are some, but just enough to get you going.


Sometimes lesser brands will add filler ingredients to their supplements to make it seem like you are getting more when, in fact, you are not. Some companies will add these components to their products so they can try to trick testing clinics into believing their supplement contains a broader array of nutrients than are actually there. Brands that load their products down with these fillers are trying to charge you more money for an inferior product, and you should try to stay away from these brands.

Thankfully for most customers, you will not find a load of unnecessary ingredients or fillers in the Optimum Nutrition Amino Energy. Since the brand does use proprietary blends in their ingredients list, it can be hard to tell exactly what you are consuming. However, they are a trusted and loved brand that has never needed to use fillers in their products. You can rest easy knowing that if you are consuming any supplement from ON, you will not be downing any fillers.


One serving of this product consists of two of the enclosed scoops (nine grams) when you are consuming the powdered form. On the other hand, if you are drinking one of the pre-mixed bottles a serving is one whole bottle.

Bottom Line

If you're in the market for an active energy boost for your pre-workout or intra workout shakes, then you've come to the right place. The Optimum Nutrition Amino Energy is an excellent choice for those who are looking for a great blend of amino acids as well as other great nutrients to help keep it going. Not only are you going to get the feel you need to make it through your training session, but you're also going to get help with muscle recovery or your post-workout needs.

Customers love all the great flavors and varieties they have to choose from with this product. Whether you want the pre-mixed bottles or the individual powder packets, you're going to get the same great benefits a fantastic taste.
