  • Ingredients Explained: L-Glutamine

    What is it?

    L-Glutamine is an amino acid, which is a building block of protein. It is naturally produced in the body and is found in many foods such as meat, fish, and dairy products. 

    L-Glutamine is also available as a dietary supplement, which people use for a variety of reasons, such as to improve their gut health, enhance athletic performance, and support their immune system.

    Why would someone take L-Glutamine?

    • Individuals that want to gain muscle or improve their recovery but do not consume enough protein with high glutamine content may consider supplementing with L-Glutamine.
    • People who suffer from specific gut health or digestion issues. L-Glutamine can improve the health of your gut, which is essential for proper digestion and nutrient absorption. L-Glutamine facilitates the cells in your gut lining, promoting growth and repair, resulting in improved gut health and easier digestion.
    • People who’re searching for natural ways of improving their immune function. L-Glutamine has the potential to enhance immune function by fighting against things that can damage it, such as inflammation and oxidative stress.

    Who’s L-Glutamine not for?

    While L-Glutamine is generally safe for most people, certain groups of individuals should reconsider supplementing L-Glutamine or consult with a healthcare professional before doing so. 

    These groups include:

    1. Individuals with certain medical conditions: If you have liver or kidney disease, you should avoid taking L-Glutamine, as your body may not be able to process it effectively. Additionally, individuals with epilepsy or bipolar disorder should consult with a healthcare professional before taking L-Glutamine, as it may interact with certain medications used to treat these conditions.
    2. Pregnant or breastfeeding women: It is not recommended for pregnant or breastfeeding women to take L-Glutamine, as there is not enough research to confirm its safety for these groups.
    3. Allergies: If you are allergic to monosodium glutamate (MSG), you may also be allergic to L-Glutamine, as they have similar structures. In this case, it's important to avoid supplementing with L-Glutamine.

    What to look for in L-Glutamine?

    Thankfully, L-Glutamine is a simple supplement that doesn't require a bunch of complex considerations.

    1. Quality: Look for a supplement that is high quality and from a reputable brand. You can check the company's website, reviews, and certifications to ensure that the product is safe and effective.
    2. Purity: Look for a pure supplement free of additives, fillers, or contaminants. 
    3. Form: L-Glutamine is available in different forms, such as powder, capsules, and tablets. Choose the form that is most convenient for you and fits your lifestyle.
    4. Dosage: Look for a supplement that provides an adequate dosage of L-Glutamine per serving. The recommended dosage may vary depending on your age, weight, and health status, so consult with a healthcare professional before starting any supplement.
    5. Price: Look for a supplement that fits your budget and offers good value for money. However, don't compromise on quality or purity for a lower price.

    How to take L-Glutamine?

    The recommended usage will vary based on the intended purpose.

    For the amino acid supplementation purpose: To take L-Glutamine for protein synthesis, it is typically recommended to consume 5-10 grams of L-Glutamine per day. This can be taken as a single dose or divided into smaller doses throughout the day. It's often recommended to take L-Glutamine immediately after exercise to help with muscle recovery, but it can also be taken at other times of the day as well. 

    For gut health purposes

    If you are taking L-Glutamine for gut health, it's best to take it on an empty stomach so that it can be absorbed directly into the bloodstream and reach the cells of the intestinal lining. It's also important to drink plenty of water to help with absorption. The typical recommended dose ranges from 5 to 10 grams per day. 

    For immune health

    There is no specific recommended dosage of glutamine for immune health, but a general guideline is to take 2-5 grams of glutamine per day. 

    When to take L-Glutamine?

    Please refer to the section outlining the recommended usage for further guidance.

    How long should I expect to see results?

    The time it takes to see results with L-Glutamine can vary depending on the individual and the purpose for which it is being used. Some people may experience results within a few days, while others may need to use L-Glutamine for several weeks or even months before seeing any noticeable benefits. 

    For example, individuals using L-Glutamine to support gut health may need to use it consistently for several weeks to see improvements in digestion and nutrient absorption. It's important to note that L-Glutamine is not a quick fix and that results may take time to manifest. As with any supplement or health-related change, it's important to be patient and consistent in your use to see the best results.

    Can L-Glutamine be used with other supplements?

    Yes, L-glutamine can be used with other supplements. However, it is always best to consult with a healthcare professional or a qualified nutritionist before combining supplements. Some supplements may have interactions with L-glutamine or may affect its absorption, so it's important to make sure that the combination is safe and effective. It's also important to follow recommended dosages and not exceed the maximum daily dose.

    What differs from product to product?

    So long as the product is pure L-Glutamine, free from additives like colours and fillers, and is manufactured by a reputable company, it is recommended that you choose a product that fits your budget or aligns with a brand that you trust.

  • Ingredients Explained: L-Arginine

    Ingredients Explained: L-Arginine

    What is L-arginine

    L-arginine, a semi-essential amino acid, is both produced by the body and available as a supplement. It plays a crucial role in various bodily processes, such as the creation of nitric oxide, which boosts blood flow and circulation and therefore in theory, improves your workouts.

    Why would someone take L-arginine

    From a training perspective, L-arginine has been shown to enhance exercise performance by increasing blood flow, dilating blood vessels, and promoting the delivery of oxygen and nutrients to muscles (Journal of Sports Science and Medicine 2005; Current Sports Medicine Reports 2009). Some research also indicates that L-arginine stimulates the production of growth hormone and insulin, which can aid in muscle growth and recovery (Nitric Oxide 2008). L-arginine may also reduce muscle fatigue and improve endurance.

    Additionally, some people take L-arginine for its potential health benefits, including improving heart health, enhancing sexual function, aiding in wound healing, and reducing symptoms of conditions such as angina and erectile dysfunction. 

    Who’s L-arginine not for

    Whilst a body of research supports L-arginine benefits in exercise performance, there are some things to consider.

    If the goal of supplementing with L-arginine is to improve nitric oxide production and exercise performance, a cheaper alternative like L-citrulline may be a better option. This is because L-citrulline is absorbed more efficiently through the intestines than L-arginine (Khalaf et al., 2019). If you have experienced gastrointestinal discomfort or bloating after taking a pre-workout, it may be due to a high dose of L-arginine mixed with caffeine.

    L-arginine may interact with some medications, such as blood pressure medications, and may cause side effects such as gastrointestinal discomfort and bloating. People with liver or kidney problems should consult their physician before taking L-arginine supplements.

    What to look for in an L-arginine supplement

    When choosing an L-arginine supplement, look for one that is as pure as possible, with the highest concentration of the amino acid. L-arginine malate 2:1 is a widely available alternative to pure L-arginine, while L-arginine malate 1:1 is less ideal. Note: Some companies may not specify the type of L-arginine on their label - don't be afraid to ask!

    How to take L-arginine

    L-arginine supplements can be taken orally. The recommended dosage can vary based on the individual's needs. Typically you’ll find that the dosages range from 1g-10g

    When to take L-arginine

    The suggestion around when to take L-arginine will vary based on the individual's needs, as well as the purpose behind its use. 

    Can L-arginine be used with other supplements

    We previously mentioned that L-arginine is a common ingredient in pre-workout supplements as a nitric oxide enhancer. However, we prefer other compounds, such as L-citrulline, over L-arginine for pre-workouts.

    Some research suggests that it may not pair well with medications, such as Viagra, so it is important to consult with a healthcare professional before combining supplements with medication, especially if you have an existing condition.

    What differs from product to product

    As previously mentioned, L-arginine comes in a variety of grades. Our suggestion? Go for the good stuff, aka 100% pure L-arginine. With that in mind, choosing between products is easy peasy - simply pick the one that fits your budget and/or aligns with your preferred brand.

  • A complete guide to fat loss supplements

    When it comes to maximizing fat loss, diet and exercise reign supreme.

    The largest determinant of long-term fat loss is the ability to expend more energy than you consume over a prolonged period of time. Put simply, if you burn more calories than you eat, you will lose weight.

    Exercise affects the “energy out” part of this equation by increasing the amount of energy you burn. Conversely, changes in diet affect the “energy in” part of this equation by helping you consume less energy throughout the day.

    However, while these two factors are unquestionably the most important when it comes to fat loss, that doesn't mean you shouldn't pursue a little help along the way. 

    Help in the form of supplements.

    With that in mind, we wanted to give you the rundown on the best (as well as legal and scientifically supported) fat loss supplements available on the market at the moment, and the how and why behind them.

    Best Fat Loss Supplements

    When it comes to fat loss, the supplement industry is rife with options -- however, like most things, some are much better than others.

    And here are the good ones:

    • Casein Protein Powder

    First up we have casein powder.

    While it is not often advertised as a fat loss supplement, that doesn't mean it won't have a profound effect on your fat loss journey (if you use it correctly, that is).

    Much like whey protein powder, casein is a refined protein source derived from dairy, where it is produced as a by-product when people make cheese. But casein is markedly different from whey in the sense that it is a slow digesting protein source (whereas whey is digested rapidly after eating).

    It is for this reason that casein is often used as a source of protein before sleep -- because it provides a steady stream of amino acids into the blood overnight, maximizing muscle protein synthesis (and by extension, muscle growth).

    However, this has an additional benefit pertaining to fat loss.

    Because it takes so long to digest, casein also blunts hunger and reduces the desire for snacking throughout the day [1]. With this in mind, it can be used in between meals as a way to lower sensations of hunger and reduce your daily energy intake during fat loss phases.

    We may be a little biased, but we firmly believe the best option on the market is the Amino Z casein powder.

    • Thermogenic supplements (a.k.a fat burners)

    Thermogenics are a family of supplements that typically combine a number of ingredients that act to increase your metabolic rate, increase energy levels throughout the day, and blunt hunger.

    Some of the more common evidence-based compounds found in thermogenic supplements include caffeine, Acetyl L Carnitine, L-Tyrosine, Theobromine, Green Tea Extract, synephrine, gamma butyrobetaine, pepper extract(s)...the list goes on.

    Now, one thing to note is that some of the effects of thermogenic supplements are a little overstated -- especially those that relate to increasing metabolism and fat burning.

    While many of thermogenic supplements contain ingredients that facilitate both of these factors, the effect is often quite small, and unlikely to have any meaningful impact on long-term fat loss. 

    But that doesn't make them useless.

    Firstly, many of the compounds in thermogenics do increase alertness, energy, and exercise performance. As a result, they can increase the amount you move throughout the day, and the amount of exercise you burn in your gym sessions [2, 3, 4, 5].

    This can lead to markedly greater energy expenditure on a daily basis.

    Secondly, many of these same compounds actually blunt hunger [6, 7]. This can lead to less snacking throughout the day, which can help with the “energy in” side of the fat loss equation, much like the casein discussed above.

    With this in mind, there may be merit to taking your thermogenic supplements earlier in the day to get the largest effect on daily energy and hunger, rather than right before your workout.

    If you are after a high quality thermogenic supplement that contains nothing but evidence based ingredients, it's hard to look past our Amino Z thermogenic supplement. 

    • Fiber Supplements

    Last but not least, we have fiber.

    Most people know that fiber is good for their overall health -- but did you know that it can also promote fat loss?

    The term “fiber” describes a specific family of carbohydrates that cannot be digested by the human gut. Breaking it down further, fiber can be classified as soluble or insoluble, depending on how it interacts with water.

    Insoluble fibers do not dissolve in the presence of water, and tend to act as a bulking agent in your digestive system, increasing the content of your gut. Conversely, soluble fiber does dissolve in water, which is why most insoluble fibers increase the speed at which food is digested.

    However, there are certain types of insoluble fibers -- namely psyllium and glucomannan -- that get extremely thick in the presence of water, and end up becoming a thick gel-like substance that fills your digestive system.

    As a result, these types of fiber can slow the rate at which your stomach empties, making you feel fuller for longer, and seriously reducing your appetite in the process [8, 9].  Like many of the other appetite suppressing supplements discussed earlier in this article, this can lead to reduced caloric consumption and associated weight loss. 

    So, if you want to get some of the fat loss benefits of fiber, start your day with something like a psyllium supplement, or even a bowl of rolled oats (which is full of fiber).

    Do you need fat loss supplements?

    As discussed above, real fat loss is derived from sustaining a moderate energy deficit for a prolonged period of time (i.e., often multiple months). And this is largely driven by maintaining a high quality diet and a solid exercise regime.

    But there is a kicker here.

    Anyone who has been on a fat loss journey knows that losing weight is hard. The more weight you lose, and the longer you spend eating fewer and fewer calories, the harder it gets. Hunger increases, energy decreases, and it becomes extremely difficult to find motivation to continue.

    Which is where supplements can help.

    By increasing energy and blunting hunger they can make your weight loss journey less difficult and more enjoyable. In turn, this can help you maintain your fat loss phase for longer, making it more effective.

    Take Home Message

    Most fat loss supplements are over blown -- but there are a select few that can have a significant impact on your fat loss journey, ultimately making it more successful in the long run.

    So if you are looking to start a cutting phase, give a few of the supplements listed in this article a go and see what you think. They could just be the thing that takes your training results to the next level.

  • Ingredient Explained: Theobromine

    Over the last decade caffeine has become known as the most effective pre-workout and thermogenic ingredient on the planet -- a reputation that is well supported by the research.

    However, we have seen numerous other compounds emerge as suitable alternatives for those that are intolerant to caffeine, or that work synergistically with caffeine to improve results.

    And theobromine is one of these.

    Step 1: What is it?

    Theobromine is a unique compound found naturally occurring in highest concentrations in the cacao plant (latin name theobroma cacao) and tea leaves.

    This particular compound was commonly used by ancient Mayan and Aztec civilizations during weddings and various other religious ceremonies due to the euphoric effect it can cause. It is also what gives dark chocolate its bitter taste.

    Theobromine is a type of compound known as an “xanthine alkaloid,” and it has a very similar structure to caffeine., which is where it derives most of its benefits.

    Step 2: What does it do?

    When ingested, theobromine works by blocking adenosine receptors in the body.

    Adenosine is a neurotransmitter that is produced by the human body. Broadly speaking, neurotransmitters are what your body uses to transmit information to cells, with adenosine being responsible for creating feelings of fatigue and tiredness, preparing your body for sleep.

    However, by blocking your body’s adenosine receptors, theobromine stops adenosine from acting on your body. This leads to increased sensations of wakefulness and alertness, improved mood, and heightened energy levels.

    Taking this into consideration, the supplementation of theobromine can have some unique benefits.

    Firstly, it has been shown to improve mental performance and cognitive function, while simultaneously reducing mental fatigue and lethargy [1]. Secondly, it has been shown to improve sensations of alertness, and enhance the ability to perform demanding tasks [2]. 

    Collectively these two factors highlight why it has become increasingly common as a pre-workout ingredient. Additionally, some of this research [2] has indicated that it provides these effects via slightly different means than caffeine, suggesting they could complement one another nicely.

    Thirdly, there is also some evidence indicating that theobromine can reduce blood pressure [3]. While this is unlikely to affect your exercise performance in the gym, it may improve long term health -- which is never a bad thing.

    Lastly, it has also been shown to increase blood flow and the secretion of key hormones epinephrine and norepinephrine. As these hormones increase both heart and metabolic rate [4], theobromine may make maintaining an energy deficit (and long term weight loss) easier.

    This is why theobromine is often found in thermogenic supplements, as well as pre-workouts.

    Step 3: How do I take it?

    The most common recommendations for theobromine supplementation is between 80 and 500 milligrams per day. This seems to be the sweet spot where you can maximize the positive benefits without any notable side effects.

    It is important to note that some research has explored higher dosages (up to 1000 milligrams per day), but this has shown negative effects on sensations of wellbeing, and has even caused decreases in alertness (similar to what occurs when you have too much coffee).

    With this in mind, we would suggest starting on the lower end of these recommendations to assess tolerance. You can then increase slightly over time as needed.

    Step 4: What are the top products?

    As we have already discussed, Theobromine is rarely sold in isolation, largely due to the synergistic effect it has with other compounds like caffeine. As such, you are most likely to find it in either pre-workout or thermogenic supplements.

    And this is what you need to look out for when you buy it.

    Firstly, make sure the ingredient list is clear.

    Because theobromine is sold in a mix of larger compounds, it is often underdosed. As a result you should try and find something that clearly describes how much theobromine contains, and it should be close to 100 milligrams. 

    Secondly, check the quality.

    If you are purchasing online, you want to make sure that the theobromine is at least 95% purity. Any decent company will provide regular lab tests on their website, so you should be able to check these for clarification.

    Lastly, don't pay too much. 

    Most pre-workouts and thermogenics are overpriced. Look for those that have minimal marketing, simple packaging, and a small amount of select, evidence-based, ingredients. And if they have a proprietary blend, ignore it.

    And that is how you find the best Theobromine containing supplement today.

  • Ingredient Explained: Huperzine-A

    Every few months a new ingredient finds its way into the market, makes a bit of a splash, and then quickly disappears into the sunset, never to be seen again.

    Which is why we take notice when a slightly newer supplement not only sticks around for a good chunk of time, but also gets some quality evidence to support its use.

    Supplements like Huperzine-A, for example.

    Step 1: What is it?

    Huperzine-A is a naturally forming compound that is found in two types of moss, being:

    1. Chinese club moss (latin name Huperzia serrata) and;
    2. Fir club moss (latin name Huperzia selago).

    The reason I have indicated that Huperzine-A is relatively new to the supplement game is because it was first identified for medical use by scientists at the Chinese Academy of Sciences in the early nineteen-eighties.

    With this in mind, it is much younger than many of the other Chinese herbs commonly used in supplements today. 

    Step 2: What does it do?

    Huperzine-A is classified as an “acetylcholinesterase inhibitor.” 

    Acetylcholinesterase is an enzyme found in the body that breaks down the neurotransmitter acetylcholine into smaller components (that are then used in the production of other compounds). 

    As such, the consumption of Huperzine-A can stop the breakdown of acetylcholine, leading to higher concentrations of acetylcholine in the body. This is important, because acetylcholine is a neurotransmitter that delivers messages throughout the brain, while also impacting your neuromuscular system.

    In the brain it plays a key role in the maintenance of motivation, increasing arousal and attention, enhancing learning and memory retention, and is even involved in facilitating deep sleep states.

    Conversely, within the neuromuscular system, acetylcholine plays an important role in facilitating the contraction of muscles, as well as the dilation of blood vessels, by acting on neurons throughout the body.

    With this in mind, the supplementation of Huperzine-A appears to have some unique benefits.

    Firstly, there is evidence to suggest that its regular supplementation can reduce some of the more severe symptoms associated with Alzhimers and dementia, including memory loss and cognitive function [1].

    Secondly, research has shown that supplementing with Huperzine-A for as little as 4 weeks can improve learning outcomes, as well as improve measures of memory and general mental function [2], suggesting it may have benefits for skill learning.

    Lastly, Huperzine-A has also been shown to increase the power of muscular contractions [3]. This may have the potential to improve training performance in the gym, increasing long-term training outcomes.

    Collectively, these results suggest that this unique supplement may have merit when taken before your workout. 

    Improvements in cognition may improve workout quality, increases in learning capabilities may improve technique efficiency (via enhanced skill development), and boosts in muscular contraction may improve gym performance -- all of which could mean more gains.

    Step 3: How do I take it?

    In the research, Huperzine-A supplementation can range from 50 to 500 micrograms per day. As such, if you are interested in trying it out for yourself, we would suggest starting with a conservative dose of 100-200 micrograms per day and adjusting as needed.

    Research thus far indicates that Huperzine-A does not require food to be taken with food, and can be taken in a fasted state without any issues.

    Lastly, anecdotal reports suggest that there may be merit in cycling Huperzine-A, where it is taken for 4-5 weeks at time, and then broken up with 1-2 week periods where it is not taken at all. This is suggested to maintain tolerance to the compound, ensuring it does not become less effective over time. 

    Step 4: What are the top products?

    If you are keen on purchasing Huperzine-A, there are a couple of things you should look out for. 

    Firstly, check the dosage. Although Huperzine-A is commonly found in pre-workout supplements, it is typically underdosed. As such, you should make sure that your pre-workout contains 100-200 micrograms of Huperzine-A per serve.

    Secondly, stick with reputable brands. Although you might find an amazing deal on Huperzine-A on ebay, there is a genuine risk that it is heavily underdosed, or even contains a completely different (and undisclosed) compound. Stick with brands that provide regular lab tests on their website so you can be sure you are purchasing exactly what you should be.

    Lastly, have a look at online reviews. Make sure that other people have had a good experience with the supplement -- because that means you probably will too.

    And that is how you find the best Huperzine-A containing supplement on the market.
