Optimum Nutrition Instantized BCAA

AminoAcidProducts | December 21, 2018 | Health

Optimum Nutrition Instantized BCAA is a top-of-the-line product that can help boost your energy in or out of the gym. A potent dietary supplement that improves endurance, burns fast and hastens muscle recovery, this is one product that will definitely improve your exercise performance.

BCAA or Branched-Chain Amino Acids are essentially the building blocks of muscle. The three that make up the BCAA are leucine, isoleucine, and valine. Of the three, the most potent muscle builder is leucine. This is why Optimum Nutrition Instantized BCAA comes with a 2:1:1 ratio of leucine, isoleucine, and valine respectively.

Is it safe to use?

Optimum Nutrition Instantized BCAA comes from a long line of products manufactured by health and fitness supplements brand Optimum Nutrition. They have been around since 1986 so they have a long history of coming up with dietary supplements that have amassed a wide following.

Legacy is not the only thing that they’ve got going for themselves. Optimum Nutrition products are manufactured not only to comply but exceed standards set by Good Manufacturing Practices (GMP). This claim can be evidenced by their strong research team and state-of-the-art production facilities.

On the ingredients side, as mentioned earlier, there is 2:1:1 ratio of leucine, isoleucine, and valine. This translates to 2.5g of leucine and 1.25 g of isoleucine and valine apiece. That’s where all the muscle-building power comes from. While it does not come with carbohydrates or sugar, it does have inulin and lecithin. Lecithin is a by-product of soy so one has to take note whether that would be a concern or not.


As specified on the bottle, you have to add 1 teaspoon to a glass ideally filled with 8 to 10 oz of water. Dilute the contents by stirring for about 15 to 20 seconds. You can also use a shaker. Cover and shake for about 10 seconds. Given that Optimum Nutrition Instantized BCAA is unflavored, you can mix it with your protein shake or your daily healthy drink. You can use this at any time. It can be a pre-workout beverage to prepare for a strenuous training. It can be a post-workout drink to help the body recover from the strain. You can also drink it during the actual workout to enhance endurance and performance.

Side Effects

BCAA rarely causes side effects. On the rare occasion that it does, symptoms most likely take the form of stomach concerns, dizziness, high blood pressure, diarrhea, and stomach bloating. Some even have reported whitening of skin but the causal link here is not clearly established.

There are some situations, however, that you should steer clear from BCAA. Taking it when you have the following conditions might be dangerous and, in some cases, fatal:

  • Pregnant and lactating women
  • Patients with Amyotrophic lateral sclerosis (ALS)
  • Alcoholism
  • Surgery
  • Low Blood Sugar
  • Ketoaciduria

Yet another concern is the soy content. This might trigger an allergic reaction. To be safe, you can consult your doctor or a nutritionist if Optimum Nutrition Instantized BCAA is a product that will work well for you given your dietary and biological conditions.


Optimum Nutrition Instantized BCAA has many benefits to offer. Here are some of those:

  • It is the first instantized formula from Optimum Nutrition which can easily mix with your favorite beverage.
  • Leucine, Isoleucine, and Valine come in 2:1:1 ratio which is very ideal for muscle building.
  • It is unflavored so you can mix with the beverage of your choice for as long as beverages are healthy. Ideal to mix with water, juice, or post-workout shakes. Avoid alcohol and carbonated drinks.
  • It is very potent as tested by an independent laboratory.
  • Stimulant-free
  • GMP-compliant
  • Was produced in a way that the powder does not readily clump or settle to the bottom


At $23.32, Optimum Nutrition Instantized BCAA 5000 is relatively affordable compared to other similar products available in the market today. Some retail closer to $30.00 to $40.00. Able to offer 60 servings, you do get value for your money if you opt to buy this product.

Customer Reviews

Here is what satisfied verified Amazon customers who used Optimum Nutrition Instantized BCAA have to say:

“Great product. Taking this before and after a workout really helps with muscle fatigue, especially if you are lifting while at a caloric deficit.” – Dan

“I used to have post-workout pain a lot after weightlifting. Then I tried doing a ketogenic diet and found I became very weak during and after the workout. I decided to add in BCAAs and lite salt to attempt to repair and provide electrolytes during exercise. It worked well. So well in fact, sometimes I wonder if I am working hard enough in the weight room. I have never quite felt this way before after weight training. I know I am making gains because I can handle more and more of a load over time. I use BCAAs all of the time now, not just while on keto. I think the difference now is that I am giving my body the opportunity to start repairing itself before it gets wore down and DOMS (delayed onset muscle soreness) sets in. I am not saying DOMS has gone totally away, but it’s gotten a ton better than it used to be, even when I was 10 years younger than I am now.” – C. Turner

“ON really goes above and beyond with their products. I have found, so far, no other casein on the market that compares with this one. Great taste and consistency. As a plus, I ordered this product with standard free shipping. That was on like a Tuesday. It arrived today, Thursday! Totally didn’t expect that, so huge thanks and shoutout to ON and Amazon for making my day a little better with that surprise!! Anywho, I got the package, pulled out the bottle, started to screw off the lid, when powder starts to fall down the outsides of the bottle. Come to find out, the airtight lid was not so airtight, and peeled what little clung to the rim off, as I unscrewed the lid. So I’m gonna return it, but do not expect any problems. If you haven’t tried this product PLEASE do! For the price, it’s by far the best out there. Good luck on your search and thanks for reading!!” – Tru Review

“I have noticed that it does take away the pain from after working out. I do have to agree with the other reviewers the taste by itself is a little bitter. I wouldn’t go as far to say it can’t be handled though. My favorite part about it there is no sucralose in it!!! If you are worried about the taste just mix it with your shake either before or after workout. I have done it both ways and the results have been the same.” – Ghosty

“Mixes well in water, however the unflavored does leave a bad aftertaste if taken plain. BUT, if you add 2 teaspoons to a gallon of water and add a few squirts of MIO water enhancer, there isn’t even a trace of aftertaste! Drink before, during and after workout. Why not buy the unflavored, which has 20 servings more than the flavored for the same price, and then flavor it however you like with a $2 MIO! BTW, it’s the main ingredient Leucine that tastes so bad, so the same problem exists with every BCAA product brand…some just mask it better than others and/or they contain less Leucine, which is the very ingredient responsible for stimulating muscle growth!” – M

There are those who were not so happy with the results. Here are some of the negative feedback Optimum Nutrition Instantized BCAA has gotten.

“Have bought other flavors of this same product before and they have tasted great. This cookie dough is by far the worst tasting protein shake I have ever had. Very bitter and but bland at the same time with horrible aftertaste. Going to be a long three weeks with this flavor. Stick with the traditional flavors or cookies and cream if you want to change it up.” – Amazon Customer

“I’ve used the unflavored for years without issue, but for some reason some of my joints have a strange, pulsing pain for 10 seconds or so after consuming this product. Perhaps it’s the faux sweeteners. I tried it on about 10-12 different days without different results so I felt confident tossing the rest of the powder and going back to unflavored. However, I decided to try another brand, Bulk Supplements, in case it was actually something with the manufacturing process.” – Benjamin Rost

“TERRIBLE FLAVOR WARNING!! The cookie dough flavor is awful. It tastes like currry. If you love curry, this is for you. If not, don’t order this one and stick to the chocolate peanut butter flavor. I’ve never tasted something so awful!” Jersey Girl

“Very unhappy. Came half full along with my other product. looks like it was used already and filled with some odd substance. Never encountered this before with supplements, will not use this brand anymore after this.” – Matt Konan

“This stuff taste horrible. I would not recommend this.” – Susan
