Before you decide on buying this product, there are a few things you should know about it. While Amino Energy has a lot of things working for it, there certainly are things ON could have worked upon and improved.


Optimum Nutrition Amino Energy Review | Effects And Side Effects

Amino Blend

The amino blend of Amino Energy has 14 different ingredients which include essential and non-essential ingredients. This blend also includes beta-alanine which helps in powering your workouts. While this blend has 14 ingredients, this is not the best approach.

None of the essential amino acids in this supplement are present in their clinically recommended dosages. We can make this out since the amino blend has a serving size of five grams which also includes non-essential amino acids.

According to us, there was certainly no point of adding non-essentials amino acids to this products since they can be produced by our body naturally whenever the need arises. Due to this, to meet the recommended dosage for the essential amino acids you will have to take up to two servings – four scoops.

Energy Blend

One area where this supplement ticks all the right boxes is the kick people get after taking this supplement. One serving of ON Amino Energy contains 160mg of their energy blend which includes caffeine, green tea extract, and green coffee extract.

These ingredients help with a constant supply of energy which is enough to power your workouts. Due to its energy blend, people prefer drinking Amino Energy as a pre-workout supplement. The added beta-alanine also helps with amplifying the effect of the energy blend.

The only drawback being, if you’re taking this supplement as a pre-workout, you might need to take two servings — fours scoops to get the desired results. Two scoops might not be enough to do the trick for you.

Additional Ingredients

This is where this product disappoints us a little. Amino Energy has a full 4.74 grams (!) of additional ingredients. Considering this product has a serving size of nine grams, 4.74 grams is more than half of the content.

The disappointing thing is, the additional ingredients don’t have any useful ingredients, the ingredients which would help you getting a better workout. This additional ingredients blend is all about flavors and colors. ON could certainly improve on it.

How To Take ON Amino Energy

While ON Amino Energy is best taken before a workout, you could also take it intra-workout, upon waking up or at any time during the day. This is one of the best things about this supplement. With this being said, the dosage of the supplement would change with the time you’re using it.

  • Pre-Workout: 2-3 servings (4-6 scoops)
  • Post Workout/Intra-Workout: 1-2 servings (2-4 scoops)
  • Morning: 1-2 servings (2-4 scoops)

Benefits of Using AmiN.O. Energy

1. Multiple Purposes

Amino Energy is one of the very few supplements on the market which can be taken for multiple purposes. You can use it as a pre-workout, on waking up in the morning, post and intra-workout and anytime throughout the day you feel you could use some extra energy.

2. Price

ON has made this supplement which suits the pocket of a huge consumer base. Keeping in mind this supplement can be used for different purposes, it can save you a lot of money since you won’t have to buy additional supplements.

3. Light Stimulant

This supplement is also a great option for people who need a light stimulated supplement. If you can’t handle highly stimulated and caffeinated pre-workout, Amino Energy is for you. This supplement is great at supplying constant energy throughout the day.

Cons of Amino Energy

1. Not Enough BCAAs

While this product has a long list of amino acids–essential and non-essential–it doesn’t have the enough amounts of BCAAs. So, if you’re looking primarily for a BCAA supplement, this product is not for you.

2. Ingredient List

While the amino blend and energy blend in the ingredient list is almost on point, this product goes berserk with its ‘additional ingredients’ list. Another thing ON could improve on is to provide the detailed list of the quantities of ingredients present in the supplement. Due to the proprietary blend, we can’t tell which ingredient is in what amount in this product.

Price / Where To Buy


This product is the perfect fit for you if you’re looking for something which you can use for various purposes. This is also a great choice if you like getting a kick before your workout. On the other hand, if you’re looking primarily for a BCAA supplement, you should look elsewhere.

  1. Love it! It actually helped with muscle recovery. The draw back I guess would be not enough energy or strong enough energy. I have to take another energy source along with it. I like being bright eyed and bushy tailed. But do notice real relief with sore muscles.

  2. Anyone else experiences itchiness? I would add 2 scoops in a glass of water and chug it before work out.

    1. Nope. Allergic reaction maybe? The only “itchiness” I would say is normal otherwise is perhaps if you get some on your lips and feel a little transitory itchiness/tingling, which beta-alanine can cause.

  3. I’ve been taking this for 1 week and have been retaining water horribly. I’m also itchy all over. Is this normal?

    1. Hi Rocio,

      If you are having adverse symptoms from taking a supplement we advise you stop using it immediately. No, what you are experiencing should not be happening. You may find the itching is from Beta-Alanine, however.
