  • When Do You Need BCAAs?

    There are literally thousands of different supplements on the market -- many of which are advertised to make a world of difference when it comes to your training.

    But let's face it, not all of them can be that good.

    In fact, this was the reason Amino Z was started in the first place -- to offer useful scientifically supported supplements at a wholesale price point.

    And one supplement that has become increasingly common in the health and fitness industry are Branched Chain Amino Acids (or BCAAs for short).

    But are they really that useful? And when should you take them?

    What are BCAAs?

    As I have already mentioned, BCAA is short for ‘branched chain amino acid’ – which is a unique type of “amino acid”.

    Just to provide a little background, amino acids are described as the building blocks of the human body. They are the little compounds your body uses to make every single protein molecule it needs.

    In essence, anything in your body that has a physical structure is made from amino acids -- and yes, this includes muscle tissue.

    Building on this a little further, there are two different types of Amino acids: “essential amino acids” and “non-essential amino acids”.

    Non-essential amino acids are considered as such because your body has the capacity to make them, meaning they do NOT have to be consumed through diet. Alternatively, those that are considered essential cannot be made in your body, and MUST be consumed through diet.

    BCAAs are categorised as “essential” and therefore must come from external sources.

    I should note that of the 9 essential amino acids your body needs, three of them are BCAAs -- being leucine, isoleucine, and valine

    Interestingly, although there are only three of them, BCAAs make up about 35% of the muscle protein in your body. And it appears to be for this reason that when they are consumed, they stimulate the production of new muscle tissue.

    Which explains why they are one of the most commonly recommended supplements on the planet.

    What are the Benefits of BCAAs?

    Given that BCAAs boost muscle protein synthesis (the production of new muscle tissue), there is mechanistic rationale to believe that they can have some serious benefits for your -- but is this really the case?

    BCAAs and Muscle Growth

    As one would expect, because of their ability to increase muscle protein synthesis, there is evidence to suggest that they can also enhance muscle growth.

    In fact, one study demonstrated that, when combined with a progressive resistance training routine, those who supplement with BCAAs after training observe greater improvements in strength and muscle size than those who do not [1].

    All of which explains why BCAAs are one of the most commonly used supplements among bodybuilders and weekend warriors alike.

    BCAAs for Muscle Retention

    Some people like to suggest that BCAAs can help promote fat loss during a cutting phase -- but this is not really the case.

    However, they do appear to be very useful when it comes to muscle retention, by slowing down the rate your body breaks down muscle tissue during prolonged periods of energy deficit.

    See, when you undertake a weight loss phase, the primary goal is to lose fat. However, this will also come with some associated loss of muscle tissue (it is an unavoidable side effect of being in a calorie deficit). Over the duration of a training phase, this loss of muscle can negatively impact your metabolism, which makes losing fat harder in the future.

    This also has some negative implications for your physique, in which you end up looking smaller after your cut.

    But taking BCAA supplements while you workout during a cut seems to mitigate the muscle loss that so often occurs when you lose weight [2]. This can keep your metabolism high, while making sure you don't lose any of your hard earned muscle in the process.

    BCAAs and post-exercise recovery

    BCAAs increase muscle protein synthesis, all while simultaneously preventing the breakdown of muscle tissue -- which has obvious implications for muscle growth and retention.

    Importantly, this also has an impact on post-training recovery.

    Evidence has shown that  supplementing with BCAAs around your workout leads to reductions in muscle soreness after training. This also appears to occur with improved gym performance during any training sessions that occur over the next couple of days [3].

    In the short term, this obviously has you feeling better -- but that's not really the biggest benefit.

    If you can perform better every single workout, this will compound over the course of a training block. Over time, this could conceivably cause much greater improvements in strength and muscle growth than you would observe otherwise.

    When do you need BCAAs?

    Now, something that I really want to hammer home is the fact that when it comes to optimizing muscle growth and recovery, the most important factor appears to be your total daily protein intake [4].

    In short, if you are eating adequate protein (1.6 to 2.2 grams per kilogram of bodyweight per day), then it is highly likely that you are maximising muscle growth and recovery without the need for BCAAs. This is going to be especially true if you consume a lot of animal protein because it is already relatively high in BCAA content (remember, BCAAs make up a lot of muscle tíssue).

    With this in mind, if you are in a calorie deficit (i.e. a cutting phase) and struggling to hit your protein requirements OR eat a lower protein diet (vegetarians and vegans come to mind here), then BCAAs are probably going to be really useful.

    Similarly, if you like to train early in the morning under fasted conditions, taking a BCAA supplement before training could offer some serious benefit.

    However, when you are training in a fed state and on days where you are hitting your protein requirements, they are not really necessary.

    This does not mean that you should not take them (I mean, why not cover all your bases), just that they are unlikely to have a huge impact.

    How should you take BCAAs?

    One thing that doesn't get spoken about often enough is when and how you should take your BCAAs.

    Which is what I plan to cover.

    Some of the evidence outlined in this article appears to show better results if you take them both before and after training. Within this, you want to try and have them between 30 and 60 minutes either side of your workout.

    Doing so ultimately ensures that you have BCAAs readily available for muscle repair and recovery both during and after your workout -- which is key.

    And when it comes to dose, the primary recommendation that appears within the published research is to obtain an intake of 200mg per kilogram of bodyweight. This means that if you weigh 80kg, you want to strive for 16 grams of BCAAs spread around your workout (i.e. 8 grams before, and 8 grams after).

    Do BCAAs Have any Side Effects?

    As far as safety goes, BCAAs are arguably one of the most well-tolerated supplements on the market. In fact, research has shown that even taking high doses of up to 35 grams per day appears to have no really negative effects.

    However, some people do experience side effects if they exceed this dose, which can include:

    • Stomach discomfort
    • Impaired exercise performance
    • Worsened recovery after exercise

    But let's face it -- you really should have no reason to exceed 35 grams per day.

    Final Message

    Evidence suggests that BCAAs can boost muscle growth, increase strength, aid with muscle retention during a cut, and enhance recovery after training.

    While BCAAs are not necessary if you are already eating adequate amounts of protein, they can be very beneficial if you train in a fasted state, struggle to hit your protein requirements, or simply want to ensure you are maximising muscle protein synthesis around your workouts.

    Within this, they may offer even greater benefit for people who do not eat much animal protein, and struggle to get BCAAs into their diet naturally.

  • 4 Ingredients That Will Boost Your Strength Gains

    It doesn't matter if you want to build huge muscles, lose excess body fat, or increase your performance, when it comes to strength, everyone can benefit.

     

    Building strength isn't just about being able to lift a lot of weight. It means being able to support yourself in a functional way. Building strength can happen at any point in life but the earlier you start, the better your chances of having an easier time in old age.

     

    Strength is built in the gym and in the kitchen. A healthy diet is key to recovery and growth. The role of supplements can play an equally important role when used in conjunction with a nutritious meal plan. There are four ingredients in particular that have been scientifically shown to promote strength gains.

     

    Let's take a look at the top 4 ingredients that will boost your strength.

     

    Whey Protein

    First and foremost is a fitness staple: whey protein.

     

    The reason whey protein is so popular in the fitness arena is because of its proven benefits. It has been shown to boost recovery, protect muscle from breakdown, support lean tissue growth, and promote strength gains.

     

    Whey protein is able to enhance your strength because it contains the very building blocks of muscle tissue: amino acids. Amino acids are quick to repair and rebuild. The end result is more muscle and more strength. (1-5)

     

    Creatine

    Creatine Monohydrate is our second choice for ideal strength boosting ingredients. Once ingested, creatine is broken down into a usable form of energy known as adenosine triphosphate; more commonly referred to as ATP. This is the preferred source of fuel for your muscles during a workout. When you supplement with creatine on a daily basis, you may be able to increase your workout performance and intra-workout strength, especially during lifts. (6-7)

     

    BCAAs

    Branched Chain Amino Acids are the end product of protein digestion. Why would you want to use whey protein AND amino acids?

     

    Whey protein is an ideal strength builder that you can take throughout the day, especially following your workout. BCAAs are equally as effective but they can be taken at different intervals. BCAAs are ideal as an intra-workout supplement to boost strength. Can you imagine trying to work out while drinking a full protein shake? BCAAs are an ideal low calorie, high octane option.

     

    What's more, BCAAs also allow you to follow an intermittent fasting regiment without the worry of protein breakdown. Just like protein, BCAAs support anabolism, recovery, and strength. (1-5)

     

    Medium Chain Triglycerides (MCT)

    One of the major things that could be stopping you from achieving the amount of strength that you want is inflammation. After a workout, you're sore and unable to perform at the same intensity as the day before. Sure, this is a sign of doing great work in the weight room but it is also limiting you.

     

    Medium Chain Triglycerides, more commonly called MCT, can help to alleviate inflammation so you're able to get yourself back in the gym sooner. (8)

     

    Make Your Own Strength Supplement

    You know exactly what ingredients you need to enhance your strength so why bother looking through hundreds of supplements when you can make your own?

  • How to Make Your Own BCAA Supplement for Insane Results

    Branched Chain Amino Acids, more commonly known as BCAAs, are an incredibly effective supplement for supporting a variety of fitness goals including muscle building, weight loss, and performance enhancement.

     

    When purchased from a popular brand, BCAA supplements can be expensive and under-dosed. If you want to avoid high cost and under-dosed supplements, the best thing you can do is create your own BCAA supplement.

     

    Let's take a look at everything you need to know when it comes to creating your own BCAA supplement.

     

    Ingredients to Include

     

    Leucine

    Considered the superstar of the three essential amino acids for fitness, Leucine is used in a variety of supplements including pre-workouts, muscle builders, post-workouts, and, of course, BCAA blends. Studies have suggested that when used as directed, Leucine may be able to promote the following benefits:

     

    • May trigger protein synthesis
    • May boost lean muscle mass
    • May increase energy levels
    • May promote fat burning (1-5)

     

    Isoleucine

    Despite not getting as much publicity as Leucine, the essential amino acid, Isoleucine is just as important thanks to its ability to manufacture functional proteins in the body. Essential for energy levels and recovery, Isoleucine may be able to promote the following benefits:

     

    • May boost intra-workout energy levels
    • May protect muscle from catabolism
    • May support lean muscle gains
    • Ideal for weight management (1-5)

     

    Valine

    The third essential amino, Valine is just as important as the others but it appeals to people outside of the fitness market as it is a great way to support recovery after an injury or surgery. As a standalone ingredient, Valine may promote the following benefits:

     

    • May help with recovery
    • May support muscle growth
    • May boost performance
    • May increase natural energy levels (1-5)

     

    Proper Dosage of Each Ingredient

     

    When making your own BCAA supplement, it will be critical to get the correct dosage. Do you know exactly how much of each amino acid you should be using? Check out the Amino Z supplement dosage guide below:

     

    Leucine

    • The ideal dosage per serving for Leucine 3,200 mg. However, if you are extremely active, you may consider using up to 4,000 mg.

     

    Isoleucine

    • The ideal dosage for Isoleucine is 1,600 mg; however, you can increase this amount to 2,000 mg, if you are very active.

     

    Valine

    • The ideal dosage per serving for Valine is 1,600 mg; however, you can increase this amount to 2,000 mg, if you are very active.

     

    Other Ingredients to Consider

     

    If you want to upgrade your BCAA supplement to the next level, you may consider adding in the following ingredients to support performance and results:

     

    Beta Alanine

    • May boost strength
    • May support muscle growth
    • May help with recovery (6-8)

     

    Caffeine

    • May boost performance
    • May increase metabolism
    • May support cognitive ability (9-11)

  • EHP Labs Beyond BCAA vs. BSN Amino X

    What is EHP Labs Beyond BCAA?

     

    EHP Labs Beyond BCAA is a branched chain amino acid supplement that is an industry favourite thanks to its properly dosed amino acid formula. Featuring a 2:1:1 ratio of Leucine, Isoleucine, and Valine, respectively, Beyond BCAA may be able to help boost protein synthesis, trigger muscle growth, and support post-workout recovery.

     

    Highlights:

    • Provides 5 grams of BCAAs, which have proven to be essential for performance, growth, and recovery
    • Features an electrolyte blend to support intra-workout performance
    • B-Vitamin complex is essential for recovery
    • Citrulline Malate has been suggested to promote intra-workout performance (1-6)

     

    Why You Should Use EHP Labs Beyond BCAA

     

    What are your fitness goals?

    Do you want to increase lean muscle tissue?

    Looking to promote healthy weight loss?

    Need to recover faster?

     

    An elite branched chain amino acid supplement can help you achieve all of these goals. The amino acids that you'll find in EHP Labs Beyond BCAA are properly dosed to take advantage of the scientifically validated 2:1:1 ratio for maximum benefits.

     

    BSN Amino X offers a greater dosage of amino acids at 10 grams per serving; however, BSN does not include a breakdown of the quantity of each ingredient. Without knowing the exact amount of the essential amino acids per serving, you can't know if you're getting the 2:1:1 ratio that is so critical for results. You can easily reach a pure 10-gram dosage of Beyond BCAA by simply doubling the dose, assuming you aren't worried about cost.

     

    Things to Watch Out for with EHP Labs Beyond BCAA

     

    Continuing with the idea above with getting a 10-gram dosage from Beyond BCAA, the label advertises itself as a 10-gram dosage. The truth is that Beyond BCAA requires you to double the dosage if you want reach that 10-gram dose. BSN Amino X, on the other hand, provides 10 grams of amino acids with one serving. The catch there is that you don't know the exact amount of each amino acid. This results in something of a draw for both brands, making them equal with the amino acids they provide in a single serving.

     

    What is BSN Amino X?

     

    Amino X features a unique amino acid and electrolyte blend. Not only will you find essential amino acids, which are necessary for muscle growth, performance, and recovery but you'll also get a variety of non-essential amino acids that can further your fitness gains.

     

    Highlights:

    • Provides 10 grams of amino acids for performance and muscle building
    • Electrolyte blend supports intra-workout performance
    • Features Taurine to boost energy levels
    • L-Citrulline is included and this may help to boost nitric oxide production (1-6)

     

    Why You Should Use BSN Amino X

     

    BSN Amino X is a high performing amino acid supplement that features the essentials as well as some extras that have all been suggested to support your fitness goals.

     

    At 10 grams per serving, BSN Amino X may arguably be superior to EHP Labs Beyond BCAA; however, this cannot be confirmed because Amino X uses a proprietary blend. Within a proprietary blend, you aren't told the exact amount of the ingredients that you're getting. Still, with that said, at 10 grams, there is a good chance that Amino X is following the scientifically proven 2:1:1 ratio.

     

    What's more, Amino X provides electrolytes to help support performance along with a few other non-essential amino acids, which may promote energy levels and recovery. (1-6)

     

    Things to Watch Out for With BSN Amino X

     

    The only thing you have to be aware of is that BSN Amino X uses a proprietary blend, which means it's a guessing game with the exact amount of each ingredient. EHP Labs doesn't do this and that alone may be the deciding factor for you.

     

    However, at 10 grams per serving, there's a good chance that your body is getting an effective dose of amino acids without the need to double dose.

     

    Conclusion

     

    You have two highly effective amino acid supplements that can both do an excellent job at supporting your fitness goals of muscle building, weight loss, and performance enhancement.

     

    If you aren't a fan of putting your trust into proprietary blends then you may opt to go with the EHP Labs Beyond BCAA. If you want a high dose per serving of different essential amino acids, then your best bet is BSN Amino X.

     

    Still not sure? Try both and see which one your body responds best to.

  • Product Review: Scivation Xtend

    If you're like most supplement advocates out there, you have a tub or two of BCAAs (Branched Chain Amino Acids) on your shelf. BCAAs have become one of the most popular supplements to pick up because of a series of studies demonstrating the numerous benefits of amino acid supplementation in regards to fitness goals. Studies suggest that using BCAAs as directed may be able to support recovery, boost lean muscle gains, and protect your from protein breakdown.

     

    One of the most popular BCAA supplements on the market, Scivation Xtend, promises to be able to do that and much more. Let's take a look to see if this BCAA supplement can deliver on its promises.

     

    PROS OF SCIVATION XTEND

     

    The first thing we noticed about Xtend from Scivation is the fact that it has a higher dosage of BCAAs when compared to most brands. It is still offering you a 2:1:1 ratio BUT the dosage itself is higher. In every serving of Scivation Xtend, you'll be getting the following dosage of essential amino acids that may help you achieve your muscle building and weight loss goals:

     

    • L-Leucine 5 grams
    • L-Isoleucine 75 grams
    • L-Valine 75 grams

     

    They also throw in L-Glutamine at 2.5 grams, which we feel is an excellent addition to a BCAA supplement as Glutamine is the most abundant amino acid found in muscle tissue. It's also used up the fastest during exercise so it's important to supplement with it.

     

    Two other additions that are impressive for a BCAA supplement are Vitamin B6 and Citrulline Malate. Both of these ingredients may be able to support your recovery while encouraging muscle development.

     

    As a whole, these ingredients working together may be able to trigger a higher level of protein synthesis to support recovery and muscle building. (1-3)

     

    CONS OF SCIVATION XTEND

     

    For those of you looking to avoid artificial additives, you'll be hard pressed to do so with Scivation Xtend. It contains artificial flavouring as well as artificial sweeteners including sucralose and acesulfame potassium, more commonly called Ace-K. With that said, we've seen supplements with much worse in it. In comparison, it's not too bad.

     

    Outside of artificial additives, it is nearly impossible to find anything else that's wrong with this BCAA supplement. Given the well-designed formula, it's easy to see why this is a fan favourite. I suppose if you really are looking for a bone to pick with the supplement, perhaps you won't agree with one of the many flavours it offers.
