  • Scivation Xtend vs BSN Amino X

    Amino acids are no longer a luxury supplement. If you look around the gym, most people will be drinking a brightly coloured powder that is more likely than not an amino acid-based supplement. The benefits of amino acids during your workout are numerous. When taken as directed, amino acids may be able to boost your recovery, trigger protein synthesis, and protect muscle from breakdown. Not every amino acid supplement is created equal. We reviewed two of the biggest amino acid supplement brands in the industry to determine which one was worth the buy.

     

    Scivation Xtend

    Where can I buy it?

     

    Pros of Scivation Xtend:

    Scivation Xtend gives you 7 grams of essential amino acids at a 2:1:1 ratio. That means you're getting the following breakdown:

     

    • L-Leucine 3,500mg
    • L-Isoleucine 1,750mg
    • L-Valine 1,750mg

     

    They even throw in 2,500mg of L-Glutamine, which is half the recommended dose but still a nice addition to a BCAA supplement. L-Glutamine may help to support fitness goals through enhanced recovery.

     

    The 2:1:1 ratio you have with Xtend is the ideal dose as demonstrated in multiple studies. Taken as directed, these amino acids may help to protect muscle mass, boost protein synthesis, and support recovery. (1-6)

     

    Last but not least, Xtend throws in Citrulline Malate, which may help to boost your energy on a ceullar level, thereby promoting fat burning.

     

    Cons of Scivation Xtend:

     There isn't much that could be considered a problem with Xtend. Sure, it has artificial flavours and colouring but so do 99% of the supplements out there. The only other potential issue is a lack of broad spectrum amino acids; however, keep in mind that Xtend specifically offers the essential amino acids. If you want a more broad spectrum amino acid supplement, you're better off taking a shot of protein.

     

    BSN Amino X

    Where can I buy it?

     

    Pros of BSN Amino X:

    BSN Amino X offers 10 grams of BCAAs per serving. That's 10 TOTAL grams of the following:

     

    • L-Leucine
    • L-Valine
    • L-Isoleucine
    • L-Alanine
    • Micronized Taurine
    • Micronized L-Citrulline

     

    As we mentioned above, those essential amino acids are going to play a helping role in boosting your ability to build muscle and protect current levels of muscle mass. They will also help with recovery, ensuring you can get back into the gym faster. The addition of Vitamin D makes Amino X a very competitive and forward-thinking supplement, especially when it comes to giving the muscles what they need to recover and grow.

     

    Cons of BSN Amino X:

    Our biggest issue with Amino X is that it is a proprietary blend. Sure, you're getting 10 grams of amino acids but you don't know the exact amount. This is important information as most studies are based on a very specific 2:1:1 ratio of the essential amino acids L-Leucine, L-Valine, and L-Isoleucine.

    With that said, seeing as how you're getting 10 grams worth of amino acids and the three most important ones are at the top of blend list, we would say it's safe to assume you're getting that ideal dosage.

     

    Conclusion

    It's nearly impossible to choose between these two amazing brands. With price aside, if we had to pick one, we would go with Amino X from BSN.

    Sure, Amino X may use a proprietary blend but if you look at the amino acids listed, there is a really good chance that you're getting the ideal dosage. We also like the addition of the other aminos along with Vitamin D as this makes for a better recovery supplement.

    Again, Xtend from Scivation isn't a bad supplement. In fact, it's a terrific supplement. If you can, buy both and see which one you see the better results with.

  • 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.

     

    SHOULD YOU BUY SCIVATION XTEND?

     

    If you are going to buy a BCAA supplement, which you absolutely need to if your goals include muscle building or fasting, then Xtend from Scivation is a perfect choice. It gives you a properly dosed formula of essential amino acids as well as several additions that only make the product that much better. Artificial flavouring aside, you are going to love this BCAA supplement.

  • Scivation Xtend vs Optimum Nutrition Amino Energy

    It doesn't matter if you're a weight lifter or an endurance runner, if your goal is muscle or performance, you know that you need protein.

     

    What about amino acids?

    Are you using them to supplement your recovery and results?

     

    Skipping the protein middle man, amino acid supplements provide you with the building blocks of muscle. If you want a quality amino acid supplement, two of the biggest names in the industry are here to provide: Scivation Xtend and Optimum Nutrition Amino Energy.
    Let's take a look at the pros and cons of both to determine which is going to be the worthwhile buy.

     

    Scivation Xtend

     

    Where can I buy it?

     

    Pros:

    • Provides the essential amino acids, which are ideal for muscle building and recovery.
    • Ensures you have the correct dosage for results.
    • May promote muscle building, faster recovery, enhanced strength.

     

    Cons:

    • Artificial flavours and colouring.
    • While this isn't a terrible thing, Xtend only offers you the amino acids that are considered essential. Many other supplements offer a broad spectrum of amino acids, including the essentials.

     

    As mentioned above, you're getting the essentials here. More importantly, you're getting the essentials at the dose that you should be for the best results.

     

    • L-Leucine 3,500mg
    • L-Glutamine 2,500mg
    • L-Isoleucine 1,750mg
    • L-Valine 1,750mg

     

    You're also getting a Citrulline Malate, which may boost your energy levels while promoting fat burning. Scivation Xtend isn't a thermogenic but it's nice to have that extra boost that may support extra fat burning and natural energy levels.

     

    Optimum Nutrition Amino Energy

     

    Where can I buy it?

     

    Pros:

    • Provides a broad spectrum of amino acids
    • Includes a nicely balanced energy blend

     

    Cons:

    • Artificial colours and flavouring
    • May lack the necessary caffeine needed for experienced supplement users
    • You're getting a broad spectrum of amino acids; however, it's all in a proprietary blend. This means you aren't sure exactly how much you're getting with each dose. At 5 grams of a total dose, it's doubtful that you're getting the necessary dosage of the essential amino acids.

     

    As mentioned above, Optimum Nutrition Amino Energy provides you with a wide range of amino acids including the muscle supporting Beta Alanine. If you're a supplement user who likes that extra kick, you'll definitely enjoy the energy blend of caffeine, green tea extract, and green coffee bean extract. While I wouldn't consider Scivation Xtend an energy booster, it certainly packs a bit of a kick with 50 mg of caffeine per serving.

     

    Conclusion

     

    The choice between the two is going to come down to what you're using it for. If you're an amino acid savvy person who is looking for FULL essential amino support in the morning upon waking, before a workout, during a workout, or before bed, you'll want to go with Scivation Xtend. If you focus more on whey protein supplementation to support your goals but you enjoy a nice amino and caffeine boost during a workout that is cost effective, go with the Optimum Nutrition Amino Energy.

  • Scivation Xtend Review

    Introduction

    BCAA products, there has been a lot of talk surrounding these products of late but is the gossip true? Or are you better off spending your money on some decent protein powder and bulk creatine monohydrate. Well Scivation have released what they believe to be the ideal BCAA formula dubbed "Xtend", and it may just be the complementary product you're been looking for to complete your supplement arsenal. So before I finish my morning power shake, let's get to it.

    Ease of Mixing - 4/5

    This unfortunately depends on the mixing technique used. Word of warning, use a shaker bottle and not a cup as the later seems to severely hamper how well the Xtend mixes with water. This being said, I have found Xtend's ability to mix with water clearly superior to any other free form BCAA product on the market. Gone are the days of choking down water with a chalky residue on top and performing the BCAA equivalent of the Milo cough afterwards.

    Taste 4/5

    This comes down to personal preference, that being said I've tried the Watermelon, Lemonade, Grape and Apple flavours, and rate them as such:

    - Grape - It tastes fantastic! Definitely reminds me of good old grape flavoured hubba bubba chewing gum.

    - Apple - Sweet with a hint of granny smith apple bitterness at the tail end.

    - Watermelon - Definitely designed to taste like Dr.Pepper, but surprisingly refreshing.

    - Lemonade - Too bitter for my taste, I was expecting something more like Kirks Lemonade, but ended up with Lemon Squash.

    Effectiveness 5/5

    Recovery, recovery, recovery people; the quicker all you potential gym junkies learn this, the quicker you will be on the road to gains. Xtend is fantastic at speeding recovery; I have been using it for the past year and have reduced my DOMS (Delayed onset of muscle soreness) tenfold. Depending on the method used for dosage, and the thickness of your wallet Xtend can truly become one of your "staple" supplements as it's really as good as the ads say.

    Nutritional Analysis 4/5

    Now onto a somewhat brief overview of the scientific base behind the components that make up Scivation Xtend, it contains:

    - 2-1-1 ratio of:

    • L-Leucine - an essential amino acid and is considered to be the strongest and most important BCAA for inducing anabolism because of its involvement in stimulating the signal for protein synthesis in skeletal muscle. Also produces a spike in plasma leucine levels further activating anabolic pathways in the body.
    • L-Isoleucine - an essential amino acid that is primarily used to help improve endurance, speed up/aid healing and repair of muscle tissue, as well as stimulate clotting at the site of injury (i.e. muscle tears created during resistance training).
    • L-Valine - an essential amino acid that is required for the smooth functioning of the central nervous system and the brain. Valine is also paramount for maintaining proper muscle function and immune system regulation.
    • BCAA's are great in supplement form because they do not require the liver to be metabolised, they are directly metabolised by the muscles themselves. Thus getting the good stuff where you want it quicker!

    - Citrulline Malate (CM) - aids in prevention of lactic acid build up during muscle stress (i.e. the burn you feel late in a set), this aids in boosting reps per set able to be performed. In addition CM can actively reduce muscle soreness post workout (DOMS).

    - Vitamin B6 - if dosage level is sufficient, B6 has been shown to increase growth hormone levels. It is also a necessary vitamin for protein metabolism.

    Value for Money 3/5

    Quite affordable dependant on personal usage and size of container purchased. I would recommend if you can afford it to purchase the large container (approx 90 serves), as this will save you a truck load of cash if the supplement is used on a regular basis.

    Overall Conclusion 4/5

    Scivation Xtend is a BCAA product that is best used in at least one of the following ways:

    - Between Meals - keeping plasma levels high between meals thus reducing catabolism (i.e. muscle breakdown).

    - Intra Workout - a very popular way to dose Xtend, as using the product this way can limit the amount of muscular damage experienced during resistance training. There is also a belief that dosing with BCAA during a workout can actively turn a workout which is catabolic by nature; into a neutral or anabolic experience due to the increased blood flow further speeding up the BCAA transport to the muscles.

    - Post Workout - can be used as an addition to your post workout shake to provide an even quicker uptake of amino acids to the muscle cells thus helping you recover faster.
