BCAAs are dietary supplements widely used in the sports field to promote recovery and muscle growth.

Derived from the English Branched-Chain Amino Acid, they make up a group of 3 amino acids known as branched-chain amino acids: leucine, isoleucine, and valine.

They are part of the 8 essential amino acids that the body cannot synthesize, making it essential to obtain them through diet.

BCAAs play a very important role in muscle formation, as they represent about 1/3 of the amino acids that structure muscles. Without them, muscle building is impossible.

There are many types of BCAAs and even more brands: how to make the right choice?

To clarify, I have compared 15 of the best-selling BCAAs on Amazon, rated them based on 6 criteria, and selected the top 3 products.

My purchase criteria

1. Form

BCAAs are generally marketed in powder or capsule form.

Regardless of the form, the effectiveness is the same. You can choose the one that best suits your daily routine.

The powder format is easy to integrate into a drink that accompanies your workout, often with different flavors to enhance enjoyment.

The capsule format is easier to transport, but the size and number of capsules needed can be significant.

No matter which form you choose, I think the important thing is to choose BCAAs without controversial additives. It’s really essential to avoid synthetic sweeteners, emulsifiers, and chemical colorants.

2. Origin

When nothing is specified on the packaging, BCAAs usually come from animal-derived by-products: feathers, animal skin, hair…

These are treated with acids and synthetic products to extract the amino acids. 

To avoid this, it’s better to choose plant-based BCAAs. They are generally obtained through plant fermentation.

However, I advise you to ensure that these plants are certified non-GMO for a more ethical and responsible consumption.

3. Type

BCAAs are marketed in different ratios:

• 2.1.1
• 4.1.1
• 8.1.1

The first number indicates the amount of leucine compared to the other amino acids. Isoleucine and valine are represented by the second and third numbers.

For example, in a BCAA 4.1.1, you will find 4 leucines for 1 isoleucine and 1 valine. 

The physiological ratio of BCAA in muscles is 2.1.1. Therefore, leucine is the most represented amino acid.

Meat-eaters generally consume enough leucine. In this case, I recommend a BCAA supplementation with a 2.1.1 ratio, equivalent to the physiological ratio.

Vegans or vegetarians naturally consume less leucine; in this case, BCAAs with a higher leucine ratio of 4.1.1 are more beneficial. 

I rarely use BCAAs with a higher leucine ratio (e.g., 8.1.1) because the interest is not proven in scientific literature. However, they can be used by athletes who need to gain muscle mass.

Since BCAAs limit catabolism and promote recovery, they can be used in any sports practice, regardless of the frequency of your training.

Best BCAA: my opinion

BEST BCAA 2.1.1 🥇

I selected the BCAA 2.1.1 from Nutripure due to the quality and purity of the active ingredients used.

These BCAAs are obtained through the fermentation of plants, including non-GMO corn. They are thus natural and 100% plant-based (so they are vegan).

This supplement contains no additives, flavors, colors, or sweeteners. A natural blueberry flavor is offered separately or in a pack if you plan to drink the BCAAs on their own. These BCAAs are made in France.

The laboratory also offers a capsule version.

Nutripure was co-founded by a high-level athlete, a five-time world karate champion. The ingredients offered by the laboratory are of high quality and minimize the use of food additives.

The manufacturing is French and the prices are fair (see our full brand review).

BEST BCAA 4.1.1

The BCAA 4.1.1 supplement from Nutri&Co laboratory is, in my opinion, the best choice given its composition and the quality of its active ingredients.

Unlike most competing products, this supplement contains all essential amino acids (EAA) and not just the BCAAs alone. It also provides vitamin B6, which works synergistically to reduce fatigue during intense sports sessions.

This formula is 100% natural, vegan, and contains no controversial additives. It is available with peach and red fruit flavor.

Nutri&Co is a reliable and transparent brand (read our full review here for more information). Additionally, customer reviews are very good.

This laboratory is based in Aix-en-Provence and places particular importance on the quality of the active ingredients in its products.

Our BCAA needs

BCAA needs vary depending on the level of physical activity. It is estimated that a sedentary person needs 84 mg of BCAA per kilo of weight, which is about 6 g per day for a person weighing 70 kg.

For very athletic individuals, the needs can go up to 150 mg of BCAA per kilo of weight, which is about 11 g for a person weighing 70 kg.

BCAAs are mainly found in animal-based products such as meat, fish, eggs, and dairy products. However, they are somewhat less represented in plant proteins.

In the context of a traditional diet and moderate physical activity, I do not recommend taking BCAA as a dietary supplement, however, I recommend it in the case of a vegetarian and/or vegan diet associated with significant sports practice.

The benefits of taking BCAA

They protect muscles from catabolism

Indeed, during strength or endurance physical activity, energy needs increase. The muscle finds its energy in its glycogen reserves.

When they are exhausted, the muscle can also use the BCAAs present in the muscle as a source of energy. This results in partial destruction of the muscle fibers.

Taking BCAAs during exercise helps provide the substrate directly, thus preventing muscle catabolism. 

They improve recovery 

Due to their anti-catabolic action, BCAAs also promote muscle recovery. Muscle regeneration will occur more easily, which will help reduce fatigue and soreness after exercise.

They may promote muscle growth

Some studies suggest that BCAAs may stimulate pancreatic cells to promote insulin release. This hypoglycemic hormone is also anabolic, which could encourage muscle mass gain. 

However, be cautious as too much BCAA intake could also promote insulin resistance, potentially leading to weight gain and increased risks of metabolic disorders such as diabetes and obesity in the long term. 

The right time to take BCAAs

For maximum effectiveness, I recommend taking BCAAs around the time of your training. The timing of intake is crucial depending on the goals you aim to achieve:

• Before training, they help preserve glycogen stores and limit muscle catabolism.
• During training, they help reduce muscle fatigue, particularly during endurance exercises.
• After training, they promote muscle repair and recovery.

Contraindications for BCAAs

BCAAs are generally considered safe for most adults, when taken in recommended doses. Therefore, it is important to seek advice from a healthcare professional before using this type of supplement. 

Excessive intake of BCAAs can cause headaches, mood disturbances, as well as nausea and vomiting. 

BCAA supplementation is not recommended for: 

• People with liver or kidney disease 
• People on certain medications, such as anticoagulants 
• People with a history of allergies to any of the ingredients in supplements
• Pregnant or breastfeeding women

In summary

To ensure you choose the best BCAAs, check:

1. The form: powder or capsules, but without controversial additives.
2. The origin: plant-based rather than animal-based.
3. The type: the ratio depends on your diet, BCAA in a 2.1.1 ratio for meat eaters, 4.1.1 for vegans or vegetarians.
