Gone Fishing For Omega 3
You can’t mention supplements without fish oil. Everyone from your grandma to the highest performing athletes are most likely on a fish oil of some kind. Why? Omega 3. Fish oil is known for its high content of omega 3 fatty acids. Specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Fish oil has been linked to a wide range of benefits, from keeping your heart and brain health, to joint and inflammation support. What Does Fish Oil Do? Omega 3 fatty acids are essential fats. This means your body can’t produce them on its own, and you’ll need to get it through either food or supplements. EPA and DHA are the best forms of omega 3. They’re shockingly found in oily fish like salmon, tuna, sardines and mackerel. Supported Benefits of Fish Oil 1. Joint Health and Inflammation Omega 3s have been shown in several studies to reduce inflammation in the body, which leads to better joint health. While not a treatment on its own, fish oil has been shown to play a role in helping joint pain, arthritis and joint stress from heavy training. 2. Cardiovascular Health Fish oil is known for its contribution to heart health. By reducing triglycerides and supporting cardiovascular function. However, these effects are more apparent in those with heart issues or poor lipids. 3. Cognitive Function and Mood DHA is an essential component of your brain. If you’re getting enough omega 3 you’ll see benefits in memory, mood regulation and perseverance. Dosages Dosages for fish oil depend on the diet of the person taking it. The sweet spot is around -3 grams of omega 3 daily. If you’re eating over 200g of salmon a day, you’re getting more than enough omega 3. While there’s no upper limit, people have reported that taking around 4-5 grams may cause gastrointestinal issues What If You Don’t Eat Fish? If fish isn’t on the menu due to allergies or dietary choices, there are alternative ways to get your omega 3s: 1. Algal Oil Not quite fish, but in the same biome. Marine algae is the only plant-based source of EPA and DHA. Whenever you’re looking for an alternative/plant based source of omega 3, this is what will come up. 2. ALA-Rich Foods Aloha-linolenic acid (ALA) is found in flaxseeds, chia seeds, hemp seeds and walnuts. Your body can convert ALA into EPA and DHA, however the conversion rate is below 10%. 3. Vegan Omega-3 Blends The real fish-less magic comes from a blend of algal and ala rich oils. These can fill in all of the omega 3 gaps more effectively than just one or the other. Final Thoughts When choosing supplements that boost heart, brain and joint health. Looking no further than a solid omega 3 source can play a very meaningful role in your health routine. Whether it’s a fish oil or a vegan blend, omega 3 in your supplement stack can make the difference in your health.

Dialed Shred Review: The Ultimate Thermogenic Fat Burner for Energy, Focus & Fat Loss
Looking for a fat burner that actually does more than just spike your heart rate? Dialed Shred by TXA is built different. This isn’t a basic stim heavy blend, it’s a clinically dosed, multi-functional thermogenic designed to support real fat loss while dialling in your energy, focus, and performance. With 17 active ingredients, branded compounds, and clinical dosages, Dialed Shred delivers intense energy, laser sharp focus, and next level fat metabolism, all while supporting gut health and nutrient absorption. Whether you're cutting, training hard, or just want a cleaner, more effective boost, this thermogenic goes beyond the basics to help you perform, shred, and stay dialed in. Let’s break down what makes this product one of the most complete fat burners in Australia. Formula Breakdown Fat Metabolism & Thermogenesis – 4.5/5 Acetyl L-Carnitine HCl (1000mg) – A well-studied ingredient that helps transport fat into the mitochondria to be used as fuel. L-Carnitine L-Tartrate (1000mg) – Supports recovery and fat metabolism. Mitoburn™ (L-BAIBA) (150mg) – Promotes thermogenesis and may improve fat oxidation. GBBGO® (15mg) – Converts to L-Carnitine in the body, supports heat and sweat output. Paradoxine® (15mg) – Helps in the conversion of white adipose tissue into brown adipose tissue also increasing energy expenditure Bitter Orange Extract (15mg) – Contains synephrine to support metabolism and energy. Strong matrix of carnitines and thermogenics, though GBBGO and Paradoxine could benefit from higher dosages for clinical effectiveness. Energy, Focus & Mood – 4/5 Caffeine Anhydrous (250mg) + Infinergy™ (50mg) – Delivers both fast-acting and sustained energy (total caffeine ~288mg). Alpha GPC 50% (200mg = 100mg active) – Supports focus and cognitive function. L-Theanine (100mg) – Smooths out caffeine’s harsh edges, improving focus and mood. Huperzia Serrata (250mcg) – Enhances memory and neurotransmission. Balanced stimulant stack for clean, lasting energy. A higher dose of Alpha GPC (active) would improve cognitive support further. Diuretic & Detox – 3.5/5 Dandelion Root Extract (150mg) Juniper Berry Extract (150mg) Mild herbal diuretics help reduce water retention. Not overly dosed, but enough for gentle support. Gut Health & Nutrient Uptake – 4/5 Glycine (1000mg) – Anti-inflammatory and supports digestion. Inulin (750mg) – Prebiotic fibre promoting gut health. Astragin® (50mg) – Boosts ingredient absorption. Alpinia Galanga Extract (200mg) – Anti-inflammatory and aids gastrointestinal comfort. A strong addition to support gut health and ingredient uptake, especially in a stim-heavy product. Overall Formula Score - 4/5 Dialed Shred delivers one of the most complete thermogenic formulas on the market, combining clinically supported ingredients with a thoughtful balance of performance, cognition, and gut support. It’s clear this isn’t just a fat burner, it’s a full-spectrum solution for energy, focus, fat metabolism, and nutrient absorption. Highlights: Dual Carnitine Complex (ALCAR + LCLT) at clinical doses to support fat metabolism and recovery. Mitoburn™, GBBGO®, and Paradoxine® for thermogenesis and increased calorie expenditure. Caffeine + Infinergy™ blend for clean, sustained energy—balanced by L-Theanine to avoid the crash. Alpha GPC + Huperzine A for cognitive clarity and mental focus. Gut health support with Glycine, Inulin, AstraGin®, and Alpinia—rare in fat burners. Possible Improvements: Alpha GPC is dosed at 200mg (50% active), which may fall short of the full nootropic benefits seen at 300–600mg active. Paradoxine® and GBBGO® are effective but dosed on the lower end of the clinical spectrum, higher amounts could amplify thermogenic impact. Could benefit from electrolytes or adaptogens for hydration and stress support, especially for those using it in fasted or high-output sessions. Flavours – 5/5 Dialed Shred comes in five fruity, well balanced flavours that mask the high actives well: Strawberry Clouds – A sweet and fluffy strawberry flavour reminiscent of strawberry flavoured lollies. Mango Passionfruit – A tropical blend combining the juicy sweetness of mango with the tangy passionfruit, offering a refreshing and exotic taste. Hubba Bubba Grape – Brings the nostalgic taste of classic grape bubblegum, delivering a sweet and fruity grape flavour. Creaming Soda Raspberry – A fusion of creamy soda notes with a hint of raspberry, providing a smooth and slightly tangy experience. Sour Watermelon – Offers a tangy and sweet watermelon flavour with a sour twist, perfect for those who enjoy a bit of zing in their pre-workout. Value – 4/5 RRP: $79.95 AUD Serves: 40 Cost per serve: ~$2.00 Higher priced, but justified by clinical dosages, branded ingredients, and multifunctional benefits. Supplement Comparison Compared to many fat burners on the market, Dialed Shred stands out for its comprehensive approach. While most thermogenic formulas rely heavily on high stimulant content, Dialed Shred combines dual source caffeine with calming nootropics like L-Theanine and Alpha GPC to deliver a smoother, more focused energy curve. Some products focus purely on thermogenesis and appetite suppression, often missing out on support for mood or digestion. Dialed Shred bridges that gap by including gut health ingredients like glycine, inulin, and AstraGin®, which is rare in this category. Who’s It For? Best suited for anyone chasing the goal of fat loss, energy, and mental clarity. Not recommended for beginners or those sensitive to caffeine. Final Verdict – 4.5/5 Dialed Shred isn’t just a fat burner, it’s a complete performance tool for those who expect more from their supplements. With a formula that hits fat loss, focus, energy, and gut health all in one scoop, it goes far beyond the average thermogenic. Clinical doses, branded ingredients, and a smoother energy curve set it apart from the typical crash-heavy options on the market. If you’re serious about getting leaner while staying sharp, strong, and switched on, Dialed Shred is built for you. It’s not for the faint-hearted, but for those who train with intent and want a supplement that works just as hard as they do. Clean energy. Effective fat burning. Unmatched flavour. This is what a top tier fat burner should look like.

Velositol® Explained: Maximise Muscle Growth with Protein Amplification
What is Velositol®? Velositol® is a patented complex of amylopectin (a type of fast-digesting carbohydrate) and chromium, designed to amplify the muscle protein synthesis (MPS) response when used alongside protein supplementation. Created by Nutrition 21, Velositol® has been shown in peer reviewed studies to double the anabolic response to protein, making it one of the most innovative additions to the performance nutrition space in recent years. Unlike typical ergogenic aids that stimulate performance through caffeine or stimulants, Velositol® operates on the cellular level, improving how efficiently the body utilises dietary protein to fuel recovery, repair, and muscle growth. What Does Velositol® Do? When consumed with protein (typically whey or plant-based protein), Velositol® is designed to: Enhance Muscle Protein Synthesis (MPS) Improve Amino Acid Uptake into muscle cells Support Lean Muscle Development Promote Recovery between workouts The primary mechanism behind Velositol® is its influence on the mTOR signalling pathway, which is the master controller of muscle protein synthesis. Research has shown that adding just 2 grams of Velositol® to a 6 gram dose of whey protein can double the MPS response compared to protein alone. This is especially relevant for athletes or individuals who consume moderate protein doses post-workout and want to maximise their efficiency. Chromium, the trace mineral included in the Velositol® matrix, plays a role in insulin signalling and nutrient metabolism. It helps shuttle amino acids and glucose more effectively into muscle cells, supporting anabolic conditions after training. Does Velositol® Work? Velositol® is one of the few ingredients with published human clinical studies supporting its claims. In a randomised, double-blind study, participants who consumed Velositol® with whey protein showed significantly greater increases in muscle protein synthesis, squat performance, and vertical jump height compared to those who took protein alone. Additional research suggests Velositol® may also: Increase insulinogenic response to protein Reduce muscle breakdown Improve recovery markers post-exercise Importantly, these effects were seen without increasing total protein intake, making Velositol® an appealing option for athletes seeking results without adding more macros. How to Use Velositol® Velositol® is designed to be paired with protein or amino acids post-workout. The clinically studied dose is 2 grams, which is often included in: Protein powders Amino acid formulas It’s most effective when used in post-exercise settings where muscle protein synthesis is naturally elevated. Products containing Velositol® are typically taken within 30-60 minutes after training to maximise its effects. Final Thoughts In a world full of buzzword ingredients, Velositol® stands out by doing something few other performance enhancers can: amplify the effects of your protein intake without needing to increase the dose. Backed by human research and designed for real world performance, Velositol® is a smart addition to any athlete's recovery stack.

The Magic of Mushrooms
In the ever evolving supplement world, you’ll either see ingredients that come through and disappear, or you’ll have some that become staples in your favourite supplements. One ingredient that falls into the latter is mushrooms. Mushrooms have been used for centuries, traditionally as medicine. In today’s world, you can find them in all sorts of supplements. From endurance, to focus, or even just plain health, let’s see what magic mushrooms can do. Cordyceps: The Creatine Counterpart A popular inclusion in pre-workouts, cordyceps have been shown to increase ATP production, like our good friend creatine. It also assists with how your body utilises oxygen. This makes it a great ingredient for endurance athletes that want that boost to go further. Taking cordyceps and creatine can make you feel like you can train forever, with the ATP increase as well as the increased oxygen utilisation. Lion’s Mane: Entry Level Ashwagandha? Lion’s mane is usually marketed as a nootropic or as a cortisol control. Containing compounds that support the growth and maintenance of nerve cells, Lion’s mane improves focus, memory and reduces stress. Much like ashwagandha, it lowers cortisol and reduces the subjective stress that you may experience. However, much like ashwagandha, lion’s mane is a saturation supplement. You can only reap the rewards when you take it consistently. Expecting results straight out the gate from a one time dose can lead to disappointment. Reishi: Calm And Collected Reishi is commonly used for its calming effects and immune support. Helping your body adapt to stress and anxiety, and even improving sleep quality. On top of that, it also helps with immune function, inflammation and may help with reducing blood sugar. Reishi is also rich in antioxidants that may support cardiovascular health by helping circulation. The anti-inflammatory properties of Reishi can reduce the risk of inflammation conditions, like arthritis. Turkey Tail: Gut Gold Turkey Tail is a go to for helping with digestion. With compounds that are similar to probiotics, it helps grow good bacteria in your gut, helping your digestive system work more effectively. It’s also been shown to boost your immune system, making it easy for your body to fight off infection, and even some types of cancer. In addition, Turkey Tail is packed full of antioxidants to help reduce inflammation. The combination of gut help, immune boosting and anti-inflammatory, makes Turkey Tail great for supporting long-term health and recovery. Shiitake: Heartbeat Hero Shiitake contains beneficial compounds that support heart health, the immune system and even help regulate cholesterol. A few studies suggest that Shiitake may be able to lower LDL cholesterol, or the “bad” cholesterol, as well as improve circulation. This can have an effect on overall cardiovascular health, immune function and general wellbeing. Are Mushroom Supplements Worth It? There’s a reason that mushrooms have been used as medicine for hundreds, if not thousands of years. Mushrooms offer undeniable benefits to your endurance, immune system, heart, and even helping fight cancer, they’ve earned their place as a staple in the supplement world. Whether it’s enhancing your focus, increasing your endurance, lower stress, or just increasing overall health, there’s a mushroom that can work its magic.
