BPI Sports has to have some of the most seductive packaging in the supplement business, every product looks fantastic, and usually lives up to the hype.

Best BCAA To Date

Their Best BCAA supplement is the product we will be looking at today.

What It Promises?

It promises to improve muscle building, increase fat loss and recovery from exercise, and improve the mind muscle connection.

Product As A Whole

It contains three BCAAs and a CLA Proprietary blend. In this review we will take a look at the three BCAAs and then proprietary blend separately before reviewing the product as a whole.

Leucine (2.5g)

Leucine is the primary Branched Chain Amino Acid and is so effective that many supplements sell Leucine as a standalone ingredient. It may help increase fat loss, is great for muscle recovery, and can also lower the rate of perceived exertion (allowing you to train at a higher intensity).

Note: A dosage of around 2-5g is usually recommended [1].


Vegetarians, and people who have typically low protein diets would benefit the most from increasing their Leucine intake. In BCAA supplements, Leucine is usually twice the amount of Isoleucine and Valine in a 2:1:1 ratio (which is the case here).

Isoleucine (1.25g)

Not to be confused with Leucine, Isoleucine is another Branched Chain Amino Acid.


It’s main function is that of an anti-catabolic ingredient.

Prevent Breakdown of Muscle Tissue

This means that it can prevent the breakdown of muscle tissue, something that can happen a lot in low protein, restrictive diets.


It will also allow for greater muscle recovery, and a net gain in muscle tissue (in other words hypertrophy). The dosage of Isoleucine in this supplement is excellent, and in line with the 2:1:1 ratio.

Valine (1.25g)

The last of the three Branched Chain Amino Acids, Valine is also the least important. It doesn’t appear to have any major benefits, and it is possible that many BCAAs could remove it without losing any effectiveness.

No Harm

On the other hand, valine is the least researched of the three BCAAs so could have unknown benefits. There is definitely no harm in adding it to your supplement though.

CLA Proprietary Blend (1g)

Conjugated Linoleic Acid (CLA) are fatty acids that are supposed to increase fat burning. Sadly there is no evidence that this is the case.

Unreliable & Weak

CLAs are unreliable and weak, and eventually the supplement industry will hopefully have given up on them. Even if they did work, the dosage is way too low, examine.com recommends 3.2-6.4g per day [2], and this product has only 1g per serving.

Final Verdict

As a BCAA supplement, Best BCAA by BPI sports is a decent product. It provides adequate amounts of each Branched Chain Amino Acid (Leucine, Isoleucine, and Valine) in the standard 2:1:1 ratio.

Proprietary Blend

Unfortunately, it doesn’t provide anything else, the CLA proprietary blend is useless, and there are no other ingredients that can help it stand out from the crowd.

If you are looking for a decent BCAA and nothing else then this is a great product for you, but there are other supplements out there that offer even more.
