What is BSN Amino X?
Highlights of BSN Amino X
- The 10 grams of BCAAs included in this blend is double the dose of what you’ll find in Optimum Nutrition Amino Energy. While Amino X may have a higher dosage, it’s important to remember that Amino Energy is a pre-workout AND amino acid supplement. Amino X is ONLY for amino acid supplementation.
- Amino X uses fewer amino acid types, deciding to focus on the amino acids that have been the subject of the most scientific studies: leucine, valine, and isoleucine.
- Amino X also includes Vitamin D, which is key for muscle recovery and hormone support. (1-10)
Why You Should Use BSN Amino X
Per serving, Amino X provides 10 grams of the following BCAAs:
- Micronized Taurine
- Micronized L-Citrulline
Optimum Nutrition Amino Energy may have more types of amino acids; however, the essential amino acids that have been proven for fitness results such as leucine and valine are in smaller quantities. That means you may have to double or triple the dose to get the same dosage as Amino X.
Things to Watch Out for With BSN Amino X
Amino X is a proprietary blend of amino acids. This can be problematic as you don’t know exactly how much of each ingredient you are receiving with every serving. However, considering that each serving provides 10 grams of the amino acid blend and there are only six BCAAs within, you can rest assured that you’re most likely getting the scientifically verified dosage that was used in several of the amino acid studies.

What is Optimum Nutrition Amino Energy?
Optimum Nutrition Amino Energy is the super charged BCAA supplement from O.N. Amino Energy is a pre-workout first and an amino acid supplement second. While it does have a lower dosage of amino acids per serving than Amino X, Optimum Nutrition Amino Energy makes up for this with a potent energy blend.
Highlights of Optimum Nutrition Amino Energy
- Provides a greater number of amino acid types compared to BSN Amino X.
- Its provides a unique energy blend sourcing the caffeine from green tea and green coffee bean, which may support fat loss.
Why You Should Use Optimum Nutrition Amino Energy
Optimum Nutrition delivers an impressive product that captures both the muscle support benefits of amino acid supplementation and the energy amplifying effects of its energy blend.
Amino Energy features 14 amino acids, all of which can help to play an important role in helping you with recovery, muscle building, and fat loss. Amino X, on the other hand, only has six amino acid types. With that said, with fewer amino acid types, the dosage for each will be higher, ensuring you are getting the levels you need for results. (1-6)
Amino Energy provides you with 160 mg of caffeine, which is slightly more than most big-name brands in the industry. The caffeine content is coming from green tea and green coffee bean extract, which suggests a metabolic benefit as well.
Things to Watch Out for With Optimum Nutrition Amino Energy
While Optimum Nutrition Amino Energy does contain more amino acid types than BSN Amino X, the dosage is only half. If you are someone who wants muscle support and doesn’t need the energy boost, then Amino Energy may not be the supplement for you.
Both of these products are fantastic in their respective categories. Amino X from BSN is an amazing amino acid supplement. It delivers a high dose of proven BCAAs. Amino Energy is a unique pre-workout and energy supplement in that it delivers both a hard-hitting energy blend AND a variety of amino acids.
If you’re focus is on heavy duty muscle building and recovery, go with Amino X from BSN.
If you want energy AND muscle support, then Amino Energy is perfect for you.
