Optimum Nutrition BCAA Pro Features & Benefits

Let’s start with quality. Optimum Nutrition (ON) makes all their products in what is called a “cGMP” or GMP-compliant facilities. ON has NSF for Sport GMP certification, which certification means raw ingredient sourcing, facility cleanliness, manufacturing processes, employee training, and non-inclusion of banned substances are all a part of such certification. And this certification is an ongoing audit as well — it’s not a one-time thing.

This is outstanding and is a real positive for ON. Their quality, produce-giving products are one of the reasons why they are so well respected in the sports nutrition supplement industry. Also, as supplement fraud still happens (although not as bad as it used to be), this certification means you NSF GMP Compliancealso get products that are not only pure in their constitution but it is free of banned substances.

Let’s talk what ON says this product will do for you. Fundamentally speaking, amino acids are the building blocks of protein and you need them so the body has the building blocks it needs to grow muscle. Bodybuilders and power lifters swear by them and if you’ve ever used them as part of your supplement regime, you know they work. That said, here is what BCAAs do in general and then we’ll talk about the ON BCAA Pro’s unique features and how it can help you.

  • Helps synthesize muscle by providing the nutritional co-factors necessary for the body to adapt to exercise stimuli
  • Provide post-workout recovery support

Continuing, Optimum Nutrition (or ON) has another BCAA supplement product but this offering has a few ingredients that the other doesn’t have. Thus, the “Pro” name in this particular product. This Pro version appears to much more robust than the “plain” version. Below is a simple graph that shows you the difference between the Optimum Nutrition BCAA Pro version and the plain BCAA option.

ON BCAA Pro Comparison

As you can see, the plain Optimum Nutrition BCAA has a total of 5 grams of L-Leucine, L-Isoleucine, and L-Valine. It also doesn’t have vitamin C, sodium, potassium, L-Glutamine, grape seed extract and red wine grape extract.

The ON BCAA Pro has all of those ingredients. Plus, it has 8 grams of the aforementioned BCAAs. It also has 5 grams of L-Glutamine. This amino acid also supports exercise recovery, immune function and muscle mass synthesis. ON doesn’t say why they added grape seed extract and red wine grape extract but a reasonable supposition is due to their high antioxidant effects. (There are other health benefits to those two elements but are beyond the scope of this article.)

What makes the ON BCAA Pro version unique? What does it do for you that other BCAA’s don’t? According to ON, here are the core competencies it offers:

  • A unique 13 grаm аmіnо blend
  • 8 gram BCAA and 5 grаm L-glutamine
  • Elесtrоlуtеѕ fоr muscle function ѕuрроrt аnd a blеnd оf synergistic ingredients with rесоvеrу supporting аntіоxіdаnt bеnеfіtѕ

Optimum Nutrition BCAA ProLet’s briefly now go over the flavor and size options that are available. Currently, the flavor options are, fruit punch, raspberry lemonade and unflavored. It comes in a 13.07 ounce (or 390 grams) black and purple canister. They do not currently have a capsule version, by the way. They only are selling it in a micronized powdered version.

Optimum Nutrition BCAA Pro Side Effects

There are no reported side effects to BCAAs in general and to this new supplement product. Of course, it’s always wise to talk to a doctor before using any new supplement. BCAAs are needed by the body so they are not going to cause any health issues.

Optimum Nutrition BCAA Pro Customer Reviews

With customer reviews, though, you get unvarnished commentary as to what a customer really has experienced with a particular product. This is a new product by ON but there are some reviews out there, though. On Amazon, it is scoring a 4.2 out of 5.00 and on, there are, as of this writing, 99 reviews scoring a 9.4 out of 10.00. Here are a few customer reviews for your perusal.

Where Can I Buy It?

Optimum Nutrition BCAA ProYou can buy it here, but you are free to choose. What’s the verdict? I give this product a 4.5 out of 5.00. As this product becomes more established and after it proves its efficacy, I will re-do that rating. As of now, though, I think the 4.0 is fair. It is a very good, high quality BCAA supplement. Is it the best BCAA? That is debatable, of course, but it certainly must be in the conversation for many reasons. I hope this review of the Optimum Nutrition BCAA Pro product has been helpful to you.
