Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this was the only product to contain a powerful dose of 2400mg of BCAAs in a 2:1:1 ratio of L-leucine to L-isoleucine and L-valine, which have been clinically proven to build muscle, increase performance, reduce fatigue, prevent muscle damage and aid in muscle recovery. Moreover, it includes BioPerine® to increase bioavailability for fast absorption directly into the muscle tissue. We liked that it’s served in a vegan-friendly capsule as well as offers a 60-day money back guarantee if you are not happy with the results. What have you got to lose? Nothing! You only have muscle to gain!

Why do we recommend Approved Science BCAA?

Main Benefits:

  • It contains pure BCAA including all 3 Branched Chain Amino Acids: L-leucine, L-isoleucine and L-valine. 
  • It contains a 2:1:1 ratio of L-leucine to L-isoleucine and L-valine, which is clinically proven to build muscles, increase energy, reduce fatigue, prevent muscle damage and assist in muscle recovery and repair.  
  • It contains a high dose of 2400 mg BCAAs for a powerful serving to maximize workout results.
  • It is vegan-friendly to ensure it’s derived from a safe source of BCAAs.
  • It contains BioPerine® which is a patented form of Piperine that has been proven to increase bioavailability, for fast and effective absorption of BCAAs into the muscle tissue.
  • It does not contain any preservatives, artificial colorings, hormones, or unnecessary ingredients that may dilute the efficacy of the product.
  • We found so many supportive consumer reviews from users who had experienced excellent results, some within as little as a week.
  • Its daily suggested serving is the optimal potency as recommended by doctors for effectiveness and is supported by extensive clinical research trials and studies.
  • This manufacturer’s customer service is second to none, it provides excellent support and help. Furthermore, it offers an excellent money-back guarantee if customers are not happy with their results.

This unique formula was the only one that we could find that was backed by solid clinical data and included this specific blend of ingredients in their potent doses.   

Performance

Natural aging affects muscle density. It becomes more difficult to build as well as maintain muscle. Whether you are a bodybuilder or trying to stave off osteoporosis, developing muscle requires protein, which is made up of amino acids. Of the 20 amino acids found in our bodies, 9 are essential and cannot be produced by the body, therefore adding these via diet or a supplement is important. Of those 9, there are 3 which contain a specific chemical structure that is branched, therefore known as Branch Chain Amino Acids or BCAAs. This unique branching structure allows BCAAs to bypass liver metabolization and instead get processed by muscle tissue to deliver a powerful surge of energy directly to the muscles themselves. Alongside dietary and lifestyle changes, there are many benefits to supplementing BCAAs to enhance muscle development. There are several key studies that help pinpoint the way when it comes to finding the most effective oral BCAA supplement.

Firstly, BCAA supplements must be comprised of pure Branched Chain Amino Acids which are L-leucine, L-isoleucine and L-valine. These are the only amino acids that contain the unique chemical structure proven to deliver energy directly to muscle tissue. Approved Science BCAA contains all three.

Secondly, BCAAs must be formulated in a 2:1:1 ratio of L-Leucine, L-Isoleucine and L-Valine.  Studies have shown this is the optimal ratio for enhancing its benefits. Approved Science BCAA contains this ratio.

Thirdly, there must be a large serving of at least 2000mg of BCAAs for a significant impact on your muscles. Lower doses may get some results but they won’t be as significant. Approved Science BCAA provides 2400 mg of BCAAs. 

Fourthly, BCAAs must be derived from a vegan source. Non-vegan sources include animal fur, human hair, duck feathers and pigskin. In order to extract BCAAs from these by-products, manufacturers use harsh chemicals which is often also reflected in the taste. But, many companies don’t make their BCAA supplement vegan friendly because it is more expensive to do so. Approved Science BCAA is vegan-friendly.

Finally, BCAA supplements should include piperine, a black pepper extract to increase the bioavailability. In this way, the BCAAs are absorbed faster and more effectively into the muscle cells for powerful results. Approved Science BCAA contains a patented black pepper extract, BioPerine®.

Many companies who enjoy a positive reputation, take advantage of their good standing with the public in order to sell cheap health supplements. It’s so distressing how easy it is, which is why it is incumbent on every consumer to do their own fact-finding on any health product they purchase.

Approved Science BCAA contains effective ingredients to build lean muscle, increase energy and endurance, decrease muscle fatigue and aid in muscle recovery and repair. What we really like is that it is made by a company that consistently uses clinical studies as a benchmark for the dosage of all their health supplements. There is also a money-back guarantee which can be claimed by speaking to their customer service agents who are real, not just bots!

Additionally, there are no added fillers, binders, additives or preservatives in Approved Science BCAA. There are so many products out there that do not fall within the realm of high standards, offering artificial alternatives and all sorts of extras inside their formulas. It is a relief to be able to recommend a company that manufactures such a unique, well-researched product.

To summarize, Approved Science BCAA provides a healthy 2400mg daily serving of all 3 BCAAs, in the correct ratio, derived from top-quality, vegan-friendly, all natural ingredients to provide awesome results. They offer a caring customer support team, confident money back guarantee at great price. From what we saw, without a doubt, this is an extremely good product.

Quality Assurance

Over the last few years, we understand how consumers have grown skeptical of nutritional and health supplements. This simply comes down to shady companies providing useless formulas that contain unrelated and non-useful ingredients or that add fillers or binders to their products. Often, these ingredients are not pure, or have been tested for quality and have no scientific validity as to why they have been included in the formulas. Not only is this irresponsible, but often quite dangerous. Truth being, there is absolutely no reason why anything artificial should be added. Natural and pure is the best.

On many nutritional supplements, the label states that the ingredients are either ‘active’ or ‘inactive’. In simple terms, the active ingredients are the reason you decided to purchase the product and the ones that actually bring you the results you are hoping for. When you see a long list of inactive ingredients, beware, often companies will fill their products with unhelpful and potentially dangerous junk.

That is why, for us, Approved Science BCAA is a product that does not fall within this category. Its formula contains only natural and pure ingredients backed by numerous clinical studies and research. It offers a simple philosophy that seems to work well – offer top-quality ingredients in the most effective potency, great price options with a terrific money-back guarantee and you won’t be disappointed.

Another aspect of taking supplements that contain a large amount of inactive or unnecessary ingredients is the lack of understanding of how these chemicals may affect existing medical conditions or medications. If the ingredients are bona fide and in their natural form, side effects or negative interactions are unlikely to be experienced.

We were very happy to discover that Approved Science BCAA is manufactured in an FDA registered facility. What’s more, is that it is cGMP recognized and complies with the US Pharmacopeia’s standards for quality and purity. This suggests that this company takes what it does very seriously, and strives to keep its products safe, natural and effective – a mentality that we totally appreciate.

Value

Approved Science BCAA comes at an affordable price with some excellent multiple purchase deals, allowing for huge cost savings for consumers. Also, this company is staunchly against any auto-ship programs, as they can be nearly impossible to cancel.

Nowadays, consumers need to be ‘smart shoppers’, carrying out as much research as they can about what they would like to purchase, in order to avoid wasting their money. There are many options out there that charge a lot of money for inferior products that simply will not deliver the results that they promise. This is disheartening and quite frankly, a bad and dishonest practice.

Orders are shipped within 24 hours, with the exclusion of any orders placed on weekends and holidays. They are wrapped and sent in discreet packaging, with no identifying marks on the outside, unlike other companies who often have embarrassing slogans or logos. Furthermore, this company provides a 60-day risk-free money-back guarantee. If you are not 100% happy with the results, you are able to return the product and receive a full refund. That shows strong confidence in its product and we totally support that kind of guarantee.

In Conclusion

When people are searching for a high-quality BCAA product, they don’t always address all the important factors which need to be considered. They may well look for effectiveness and affordability. However, as we found out, there are other significant elements to bear in mind, such as third-party testing and comprehensive customer reviews that give us a great indication of how the product really works.

Approved Science BCAA pills specifically contain 2400mg of a 2:1:1 ratio of Branch Chain Amino Acids in a powerful dose which is clinically proven to build lean muscle mass, increase energy and endurance, decrease muscle fatigue and aid muscle recovery and repair. The ingredients are:

  • Pure and natural BCAA with all 3 Branched Chain Amino Acids, L-leucine, L-isoleucine and L-valine. 
  • 2:1:1 ratio of L-leucine to L-isoleucine and L-valine, which is clinically proven to build muscles, increase energy, reduce fatigue, prevent muscle damage and assist in muscle recovery and repair.  
  • High dose of 2400mg BCAAs for a powerful serving.
  • BioPerine® which increases the absorption of the BCAAs for proven efficacy.
  • Derived from vegan sources without any harsh chemical processes or questionable ingredients.

Additionally, there are other significant elements to bear in mind, such as third-party testing and comprehensive customer reviews that give us a great indication of how the product really works.

Of all the products that we reviewed, across all parameters, none compared to Approved Science BCAA. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution to building muscles, preventing damage and aiding muscle recovery, you would be hard pushed to find anything better than Approved Science BCAA.

“This is my first time using a BCAA pill and, after a month of taking it, I am hooked! I had been spending more time at the gym but I wasn’t getting the results I was looking for. I shared my frustration with one of the trainers there and he pointed out I wasn’t giving my muscles enough recovery time. I did some research and realized that I was really punishing my muscles and needed to do something about it. I take Approved Science BCAA as soon as I’m done with my workout and it has been a godsend! I finally have the muscle growth I’ve been wanting and best of all, I feel refreshed before my workouts. I didn’t even realize how tired my muscles were until I woke them up with this awesome product. If you want your hard work at the gym to pay off, you should definitely order these pills.”  – Shane Dixon

“I’ve been drinking BCAA in my smoothies for a while now and I love what it does for me. Unfortunately, I started a new job that doesn’t leave me a lot of flexibility or time to make my smoothies. So, I was looking for pills that I could have on hand for when I didn’t have enough time to make my smoothies. These are great! They are so transportable and easy to take. I take them even on days when I don’t work out and I can really feel my muscles healing. My workouts have gotten better and I definitely have more stamina than before I started taking this. Thanks for making such a great product!” – Derek Sanders

“Since I became vegan, I haven’t found a solid BCAA product that I felt was really doing anything for me. One of the reasons why I actually became vegan was because I read about all the terrible things that manufacturers use in their BCAA supplements. Things like feathers and hair from animals! Anyway, just trial and error had me trying out different products. I only try products which have a money-back guarantee. Approved Science BCAA had a much longer guarantee than other brands, which is fantastic. Being able to try these pills for almost 2 months let me see everything I needed to in order to decide if I should keep this or not. By the end of the second week I could see a difference and after 3 weeks I ordered some more! If you’re thinking of trying this, you should. You absolutely cannot lose. This is one very happy customer.” – Colin Barnes

“My boyfriend uses Approved Science BCAA to bulk up and it really never occurred to me that it could be good for myself as well. It wasn’t until my doctor told me that I had osteopenia that I even realized what bad shape my bones were in. My doctor told me I needed to strength train, but it was so difficult for me. Even light weights tired me out like crazy. I was losing motivation to continue with my workout schedule, so I thought I would try BCAA. It’s amazing what this has done for me! This totally takes away my soreness and gives me an amazing boost of energy. I can see how much stronger I’m getting and I love it! I finally have definition in my arms, which I am so excited about! These pills are definitely not just for men! My doctor gave me a much needed wake-up call. If you haven’t had your bone density check, I would get on it and then check out these pills. Highly recommended!”  – Trinity Morales

“No matter how hard I tried I just could not lose weight. I was waking up at 5am to go jogging but the scale would just not move. It was so frustrating! My husband kept telling me that I was gaining muscle, but even he could see that wasn’t true. I was at my wit’s end especially because my husband hardly ever worked out but always looked fit! Jerk. He told me it was because he was taking BCAA. I couldn’t even believe it could make that much of a difference. He was told that if you maximize your workouts by using BCAA, you could work out less and get the same results. So I tried it and I was astonished! Literally! You cannot believe how exercising less and taking BCAA is what helped me. I am so shocked that I had to write this review. The numbers on the scale have finally started to dip and I looked so toned. I love my new body. Thank you!!”  – Cassidy Coleman

“I used to be able to work out and maintain my muscle mass easily but as the years go by, the maintenance is not the same. It can feel like a hamster wheel – going around and around and never getting anywhere. When I was under the weather and couldn’t work out for a week, it took me a month to get back to where I had been. When I take Approved Science BCAA before I work out, I feel a strength and energy that has been missing for a while. It makes working out more enjoyable and I can actually maintain my muscles. What a relief! This is one of those products I could not live without. Keeping myself exercising into my golden years will definitely keep me living the active lifestyle I have now. Fantastic product!” – Raymond Pierce

“This is the best BCAA product! I fell and broke my wrist a year ago and it has been so hard to build up my strength. I went from playing tennis every day to sitting at home. I was in bad shape both physically and mentally. My recovery has been very slow and discouraging. My physical therapist was the one who told me about BCAA because she thought it could help my predicament. I’ve tried different brands and couldn’t tell if they were helping me. When I saw Approved Science BCAA and read the label, I realized it was double the BCAAs that I was currently taking. After starting with Approved Science, I have seen real results. Having the stamina to get through a physical therapy session and then being able to recover and do it again the next day, is helping me build my strength. I know that I will get my life back soon and it’s thanks to Approved Science BCAA!” – Peg Cummings 

FAQs about Approved Science BCAA:

How does Approved Science BCAA work?

The key lies in the ingredients contained within this formula – they haven’t simply been plucked from thin air so that they have a list of ingredients that looks good on the label! Each ingredient in this product is supported by clinical research and has a reason to be there! Its unique formula is based on clinical studies that have shown huge promise in building muscles. By including key BCAAs to target muscle mass, it works to stimulate muscle protein synthesis and assist muscle recovery. It has included effective ingredients L-leucine, L-isoleucine and L-valine in a 2:1:1 ratio in a highly effective dose (2400mg) to ensure optimal effects and fast results to boost muscle development. 

What’s more, this product includes BioPerine® for enhanced absorption and faster results. This unique formula works to boost muscles and prevent muscle damage as well as aid muscle recovery. The great thing is that this formula is all natural and vegan-friendly which means that it is safe for long-term use.

Do all BCAA products work in a similar way?

The short answer is basically no, they do not. There are many companies that just ride the trends, producing inferior products with weak formulas in the wrong proportions. Many use incorrect ingredients, fillers, binders or even worse ingredients that can affect desired results, and can even be dangerous.

What should I look for in an effective BCAA formula?

  • It should contain pure BCAAs with all 3 Branched Chain Amino Acids, L-leucine, L-isoleucine and L-valine.
  • It should contain a 2:1:1 ratio of L-leucine to L-isoleucine and L-valine, which is clinically proven to build muscles, increase energy, reduce fatigue, prevent muscle damage and assist in muscle recovery and repair.  
  • It should contain a high dose of 2400mg BCAAs for a powerful serving to maximize workout results.
  • It should contain BioPerine®  proven to increase bioavailability for fast and effective absorption of BCAAs into the muscle tissue.
  • It should be vegan-friendly to ensure a safe source of BCAAs.
  • It should not contain any binders, fillers, additives, hormones, preservatives or artificial ingredients.
  • It must be 100% pure, natural and with no unnecessary ingredients that could reduce the effectiveness of the product.
  • It should be formulated using the same potency as found effective in clinical studies.

Are there any side effects noted when using this product?

Our research did not uncover any negative side effects when using this product. The ingredients that are contained within the formula of Approved Science BCAA are all natural and pure, what’s more, they are doctor approved, so the lack of any negative effects is to be expected. That said, as with any supplement, we always recommend consulting with a doctor if you are pregnant, breastfeeding, have an existing medical condition or are taking any other medication.

What are the dosage instructions for Approved Science BCAA?

On workout days, the manufacturers of this product suggest taking 2 capsules per day, either before or after exercise, with a glass of water. On non-workout days, it is suggested to take between meals, once in the morning and once in the afternoon, in order to maintain levels of fitness. 

As with any medication or supplement, always follow the recommended dosage instructions and do not exceed them as this poses health risks.

How long before I can see any results?

Results will vary for each person. For some, they will see changes almost immediately, for others it may take longer. It is different for each person. Other factors that affect results can include age, diet, and lifestyle so it is hard to say exactly. What you should look out for are those companies who offer a satisfaction guarantee. This suggests that they are confident that their products will deliver the desired results. And after all, if you don’t get the results you were hoping for you can always return the product. Approved Science BCAA offers a great money-back guarantee and awesome feedback on how well this product works.

What price should I expect to pay?

The costs of products vary among manufacturers. Unfortunately, many are cheap, useless supplements that have been formulated without any science-based evidence to back them up. Some of these companies are selling their products for over $100 per bottle, which is very expensive. On average, the best supplements we found are selling between the $40-$50 price range. Often, when products appear cheaper, this is indicative of low quality or a low recommended daily serving, which will not bring the results you are looking for. Be aware. Read the labels.

Which BCAA product should I buy?

As each person’s experience of a product is different, it is difficult to say specifically which one is the best. That said, based on several factors, we did like Approved Science BCAA. We found that from the 50 products that we looked at, Approved Science BCAA had the best quality of ingredients, potency and strength, positive consumer feedback and the manufacturer’s customer service was excellent.

How safe is it to order over the internet?

Approved Science BCAA is safe to be ordered over the internet. The manufacturer utilizes the latest encryption software to protect your credit card information and do not engage in shady schemes such as ‘automatic billing’ programs like many other companies do. They also deliver very efficiently and quickly, using discreet packaging.

There are several reasons why we liked this product including purity of ingredients, customer service, satisfaction, and effectiveness. Its formula is backed by clinical studies and we feel it values consumers’ health above and beyond the profit margins.

This is a great product that you can depend on. It has a well-researched formula with the right ingredients in the correct potency. And if that wasn’t enough, check out the customer reviews – they say it all. It counts with many happy customers clearly singing the praises of this trustworthy product who are highly loyal to this brand. We will summarize the key benefits one more time:

The Bottom Line

At the end of the day, the bottom line is that consumers have so many options when choosing a health supplement. We are constantly being bombarded with commercials, advertisements and messages about so many different products for varying health issues that it is beyond confusing which ones are the real deal and which ones are a waste of time. BCAA supplements are no exception, with many companies simply trying to cash in on the latest health trends and pushing their products on unwilling consumers.

We like Approved Science BCAA because we feel that this company is different. It is in it for the long haul. It has researched its ingredients well and produced its formula using only pure natural ingredients with a lot of clinical data to back them up. The manufacturer of Approved Science BCAA offers what more companies should – an effective, affordable product supported by a real concern for the health of their customers. As an added bonus, Approved Science BCAA has many happy testimonials to support our belief that this is a great product and a great company.
