Pure BCAA formula

Effective at increasing muscle growth

Boosts metabolism

Taste is bitter

Read more

Effectiveness

Because of its pure and patent BCAA formula, this is the ideal powder for CrossFit, bodybuilding or powerlifting. That’s because athletes can see results fast when it comes to building lean muscle thanks to the boost in protein synthesis that also minimizes tissue damage from heavy lifting or intense training. Those who drink before working out can expect an increase in energy to train harder or longer. It’s also great for recovery and reducing inflammation.

BulkSupplements powder features a 2:1:1 BCAA ratio. It contains no sugar, dairy, soy, yeast, gluten or additives. It is among the top-ranked BCAA supplements by labdoor.com for its purity and ingredient safety.

Taste

This isn’t an option known for its taste. It can be pretty bitter, but at least it doesn’t have added sugars. It’s a good idea to add the powder into a smoothie to help get it down.

Value

It’s suggested that the consumer take 1500 mg (rounded 3/4 tsp) three times daily. For the best results, take 20-30 minutes before exercising. This powder is effective at building muscle, is all about a fast recovery post workout, and even boosts metabolism. And for a reasonable price, it is well worth buying.

Pros:

Performs well at kick-starting protein synthesis

Highly rated by third-party testers

Affordable

Mixes easy

It is stimulant-free, to be used either before endurance training or after strength training to help with muscle building. This is a high-quality option that is known for its ingredient purity and overall efficacy.

Read more

Effectiveness

Those who hit a plateau should try this BCAA powder. It performs extremely well and its effects really were seen when in the gym. Because it works well as aiding in recovery, consumers can get right back to working out and then see an improvement with their own performance, as well as with their muscle definition. Expect to have less muscle fatigue and post-lifting pain.

Ingredients

This option has 5 grams of BCAAs per serving with a 2:1:1 ratio, and is ranked high by labdoor.com for its product party and ingredient safety. However, it does contain soy for those who have an allergy.

Taste

Optimum Nutrition’s powder comes in both flavored and unflavored options. However, it is not known for its taste. The unflavored option is chalky and many recommend mixing it with a shake or smoothie (or even flavored whey protein powder) to help mask the taste. The flavored options might be the better bet for most.

Value

One container includes 60 servings per container, and it can be added to a drink before, during or after strength and endurance training. It does a great job at reducing soreness and building muscle without added stimulants to make the athlete feel jittery. Plus, it’s sold for an affordable price.

Effectiveness

Although this is stimulant-free, consumers will be pleased with how well to help amp them up when in the gym thanks to its BCAA blend.

Many also report how lean they notice themselves getting when working out consistently when adding this powder into their routine.

Value

It’s recommended that the athlete mix one scoop in 6-8 fl ox of any water before, during or post-workout. It’s best to do this twice per day to reap all its benefits. And at just under $20, this is an option to pick up. There is 30 servings per container and is recommended to add one scoop per drink. At about $25, it’s also reasonably priced.

Criteria Used for Evaluation

Effectiveness

The effectiveness of the powder is, of course, something we are in invested in determining. We want to include only the most effective powders on this list. There is also the timing of ingestion to consider. What powders work best when used beforehand? What ones work best post-exercise? We considered over 1700 reviews and listened to what actual people who had taken these products had said about each product on our list.

Product Purity

The ratio of how the amino acids break down is the first thing we look at when selecting powders for this list. The ratios can range from 2:1:1 all the way up to 12:1:1. Conclusive studies have only been done on BCAA powders featuring a 2:1:1 ratio of amino acids along with some minor studies on a 4:1:1 ratio. We tend to favor 2:1:1 ratio powders for this list since they have the most evidence supporting their ability to aid the athlete.

We take a close look at the construction of the BCAA powders outside of their amino acid content. Some powders contain sugar for flavor which can be a poor addition to certain diets. Many powders also add caffeine as a means of providing additional energy. We also go through and check out the other additives that are added to the base BCAA powder to assess what combination is best for athletes.

Many BCAA powders also feature glutamine, making it a powerful combo. Glutamine is an amino acid that differs from the branch-chain ones but is also important when it comes to muscle repairing. After a workout, glutamine levels are low and take time before they are back to their levels. The two kinds work extremely well together to help ease strain and stresses of the muscles when working them hard. When with BCAAs, glutamine helps to further prevent overtraining, aids with promoting protein synthesis (and thus muscle growth), and even supports immune system function.

Value

Our assessment of the price of the powder comes down to a couple of key factors. Is everything the powder provides worth the price? Is the amount of powder your getting worth the price your paying? How much is the price per serving? If we feel that you are being unfairly charged then we won’t include that BCAA powder on the list.

Ease of Use

Taste isn’t any less important but our assessment is a bit limited. There is often little that can be done to avoid flavoring issues when using supplement powder and it technically doesn’t affect the powder’s performance. We do well to avoid putting powders on this list whose flavoring is too unpleasant or simply isn’t worth the benefits they may provide.

Another thing we took into account was how easily the product dissolves in liquid. We found that most products of this type, whether it's on our list or not, don't completely dissolve, it's simply a matter of how much or little dissolution there is.

We research to look for any recorded negative side effects of certain BCAA formulas. If a powder has too much negative feedback it will not make to the list and if even minor side effects exist it is something we believe is worth mentioning.

All of the BCAA supplements on this list are specific powder options. However, BCAA supplements are also available in capsule form. So what is the difference and which one is better?

Keep in mind that the best form really depends on each specific consumer. Some simply do not like swallowing pills, which makes powder the perfect option. Others already take other vitamins and/or supplements and might not want to or may forget to take their BCAAs. Powders are believed to be better absorbed in the body since they don’t have that barrier capsules have. Capsules also don’t have the capacity to be packed with other vitamins or amino acids because there is only so much room. Think of whey protein as a good example here. The taste might not be ideal for some when it comes to powders, but brands offer various flavors to help with this problem.

What this can do for you?

Athletes can use this powder before, during, or after their workout in order to improve their efficiency or to reduce the post-workout stress on their body.

Watch your intake

Whenever you start taking supplements, read the labels and see how you feel before taking a full serving.

Other Factors to Consider

Bottom Line

The supplement market can be especially difficult to sort out. Not only are there a lot of options with similar features, there are plenty of others with pseudoscience or exaggerated claims that try and take advantage of naive athletes. We not only weeded out the supplements that work, we specifically had to narrow the list down to only the very best of the ones that did.

There are many benefits to adding BCAA powder supplements into an athlete’s regimen. However, many may be wondering if it is necessary to start using the supplement at all?

Leucine, isoleucine, and valine are three (out of the eight) essential amino acids that are not made in the body. Because they give that extra energy to the muscles and prevent muscle breakdown, it is important for those who lift, run or do any other physical activity to make sure they are getting these amino acids somehow.

Use

It’s recommended to get leucine is 42 milligrams,19 milligrams of isoleucine, and 24 milligrams of valine. for every 2.2 pounds of your body weight. According to the NYU Langone Medical Center, the best sources of BCAA from our diet include eating meat, chicken, fish, dairy, and eggs. Women who get their daily protein of 46 grams and 56 grams for men will get enough BCAAs from their diet. However, those who are sick, injured may want to increase their BCAA intake. And since BCAAS help promotes muscle growth and repair muscles to decrease soreness post intense workouts, those who workout often should also make sure they get more than their recommended daily serving—which is where BCAA supplements come in.

Frequently Asked Questions

q: What are the side effects of BCAA supplements?
a:

Taking too many branch-chain amino acids can reduce the number of certain hormones that make it to the brain, such as serotonin. This is can limit how good you feel post exercise. These sort of side effects should only occur when a BCAA supplement is taken inappropriately.

q: Can I use BCAA powder with pre-workout supplements?
a:

Some report adverse effects when mixing pre-workout supplements such as elevated heart rates. You should read extensively about the content of both supplements before combining anything. We recommend avoiding any combination that contains a stimulant, such as caffeine, before a workout.

q: When should BCAA supplements be taken?
a:

Because of their benefits, BCAA supplements can be taken before, during or after a workout. Many prefer to add to water and drink before and then after an intense workout for peak performance and recovery.

q: Does the powder dissolve easily?
a:

Usually, but it depends on the brand of powder. Since powders that do not mix well tend to leave a chalky aftertaste and texture, we recommend avoiding powders that don’t dissolve easily and quickly. This list won’t feature many powders with this issue, although sometimes a really great product will have this issue and since it isn't the most important factor we will still leave it on the list.

q: Is there an aftertaste?
a:

A: Some powders do have an aftertaste. We recommend selecting flavored powder that is intended to be mixed with water or mixing the flavorless powder into a smoothie or a shake to avoid flavoring issues with your BCAA powder.

q: Does the powder result in stomach issues?
a:

The more potent powders can cause cramps and other issues with sensitive stomachs. The best way to combat this is to closely read the ingredient list. You can make sure to avoid powders containing any allergens such as gluten, soy, or dairy, as well as powders with stimulants which can also cause stomach problems.
