The Best Amino Acids For Weight Loss

I am the first person to sympathise when it comes to the struggle of losing weight.

I know that it can be incredibly difficult to stay motivated, especially if your results plateau. Even worse can be feeling that rather than shredding fat, you’re simply losing hard earned muscle.

If you follow current fitness trends, you probably know that one popular way to boost your fat burning potential is to use amino acid supplements.

Amino acids are the building blocks of protein and are vital to our bodies.

Studies have shown that branched chain amino acids (BCAAs) can aid weight loss while maintaining lean muscle mass.

I know it’s the dream and sounds too good to be true, but research backs it up! So read on to find out more about the best amino acids for weight loss.

Who Should Use Amino Acids For Weight Loss?

Perhaps you’re just at the beginning of a weight loss journey and you want to get the best start possible. Maybe you’ve been losing weight successfully for a while and your results have plateaued.

Or you’re frustrated because your hard work in the gym isn’t paying off as the majority of your weight loss is coming from a loss of muscle rather than fat.

If any of these scenarios fit your current situation, then BCAA supplements could be beneficial for you.

Promising results from research into the benefits of branched chain amino acids has lead to their increasing popularity throughout the fitness community.

The benefits that amino acids provide suggest that anyone dedicated to achieving their weight loss goals could get a helping hand from BCAAs.

What Are Amino Acids?

Protein is essential to maintain a healthy body.


Protein synthesis is needed for everything from growing your hair and nails to building strong muscles. All of our cells contain protein and what makes up protein? Amino acids of course!

There are 20 amino acids within the human genetic code and nine of those are classed as “essential”. This means that your body cannot produce these amino acids on its own so it needs to get them either from the food you eat or from supplements.

What Are Branched Chain Amino Acids?

BCAAs are made up of three essential amino acids - isoleucine, leucine and valine.

BCAAs help to retain lean muscle mass by aiding protein synthesis. This can be incredibly helpful for burning fat while dieting.

If you are looking to reduce your body fat percentage, you will need to restrict your caloric intake. However, normally when this happens your body fights as hard as it can to hang onto your fat stores. It breaks down muscle mass instead.

As BCAAs retain lean muscle, your body is forced to burn extra those extra pounds of fat.

How To Choose The Right Supplement

If you have no experience with supplements and setting fitness goals is new to you, choosing the right supplements can be daunting.

There are literally hundreds of companies trying to market the same thing all in different ways! But don’t panic, I’m here to help!

First of all, when it comes to weight loss you want to look for a BCAA supplement with the highest amino acid value per serving. This is the best way to achieve your goals.

My other piece of advice is to look for a pure product. The fitness supplement market is big business. Although there are lots of genuinely helpful products that do exactly as advertised, there are also products packed full of nasty fillers.

To be sure of quality, look for a product that is made in the USA and third party tested for purity.

Our Choices

I’ve looked at all of the top BCAA supplements currently available and selected 5 to discuss with you today.

I have tried to pick a wide range of products covering all available forms and prices in hopes to find something for everyone. I have listed some pros and cons for you to make your own decision. At the end you’ll find my personal overall favorite.

I’ve got to admit, I’ve had experience with this product before and I really like it.

It’s 100% pure BCAAs. No additives. No fillers. It is also made in the USA and is tested for guaranteed purity. It’s free from soy, gluten, yeast, sugar and dairy.

Even the packaging is pretty basic which I like. It just does what it says on the tin and lets what’s inside speak for itself. There is no gory marketing screaming “please buy me” which is what I like the most about it.

It comes in a small resealable pouch which is handy for keeping in your gym bag. A single serving doesn’t offer a huge amount of BCAAs, just 1.5 grams.

However, as there are no other ingredients that could potentially be dangerous in higher doses, you can take larger doses if you wish. Plus each pouch offer 166 servings! So even if you double your intake, it will still last you quite a while. Considering how many servings are in each pouch it is incredibly reasonably priced.

There is one big downside though and that is the flavor. Because there are no sweeteners or artificial colors to flavor it, it tastes really bad. One way to combat that is to mix it with your post workout shake or something strongly flavored like making it into a fruit smoothie.


  • 100% pure BCAAs
  • No additives
  • Free from soy, gluten, yeast, sugar, dairy
  • Great price
  • Large supply
  • Made in USA


  • Low serving of BCAAs
  • Bad taste



Our rating

This one comes in a great serving size of 90 servings per tub. It also offers 7 grams of BCAAs per serving which is excellent.

It has zero calories and carbs and adds in some essential vitamins and minerals.

This brand is a little bit more expensive than the others but I think it’s pretty reasonable considering the serving size.

The one thing that really let this product down for me is the fact that it includes lots of artificial sweeteners and colors.


  • 7 grams BCAAs per serving
  • Zero calories, carbs or sugars
  • Added vitamins
  • Wide variety of flavors
  • Reasonable price


  • Lots of unnecessary additives



Our rating

This product is especially for the ladies! Us girls have different bodies to men in the sense we store more fat and tend to store it in different places. In terms of achieving weight loss goals, it is good for women to have a product designed with them specifically in mind.

This option offers 5 grams of BCAAs per serving but has no calories, carbs or sugars. The only added ingredients are some vitamins and minerals that restrictive calorie diets tend to leave us deficient in.

Again, this is quite a small tub only offering a 30 servings but it gets excellent feedback from ladies currently using it. Many have stated how well it works for recovery as well as some mentioning it has helped to curb their appetite.

The one thing the majority of people have said though is that it has an incredibly sweet flavor. Therefore, if you do not have a sweet tooth it might not be your favorite!


  • 5 grams of BCAAs per serving
  • Designed for women
  • No calories, sugar or carbs
  • Added b vitamins and magnesium
  • Helps recovery
  • Could curb appetite


  • Small supply
  • Super sweet taste

This is the first powder supplement on our list. You use it in the traditional way as a pre/post workout shake.

People who used it commented that the flavor isn’t the best and it’s a little chalky in consistency. If you use shakes already though, you could mix it in with your existing shake to solve that problem.

It comes at a reasonable price but only offers 30 servings. It also has an okay dose of BCAAs - about 5 grams per serving. This isn’t bad, especially for those using BCAAs for the first time, but could be a bit higher.

It also contains the amino acid glutamine which is really helpful for recovery.

The one thing I didn’t really like was that it has lots of additives like artificial flavors and sugars. However, if you are looking to give a BCAA supplement a try and want a smaller supply at a reasonable price, this product could be a good option.


  • 5 grams BCAAs per serving.
  • Special recovery formula
  • Good price


  • Too many additives
  • Small supply



Our rating

This is a capsule BCAA supplement which will work well for those who don’t do workout shakes. You just take two capsules daily and you’re done.

What I like about these is they are just BCAAs - no unnecessary filler products or additives like caffeine. The only other ingredients are those necessary to make the capsule coating.

They come in at a pretty reasonable price too but they only offer a 30 day supply.

They get great feedback from people who used them, especially noting that they really improve your recovery after a hard workout. This is great in terms of weight loss as it means you’re not too sore to workout again the next day.

The one thing that let these down was they offer a pretty low dose of BCAAs at only 1.6 grams per serving. However, if you are new to BCAAs and want to slowly build up towards a high dosage, these might be a great starting point.


  • Capsule form
  • Pure BCAAs
  • Good for recovery
  • Good price


  • Low dose of BCAAs
  • Small supply

My Choice

Overall I like the Bulksupplement brand the best. The reason is that it’s totally pure without anything added.

Keeping it simple is always the way I like to go with when it comes to supplements.

If you have tried any of my picks or have another favorite, I’d love if you’d share your experience in the comments.
