BSN Syntha-6 Edge Review

BSN Syntha-6 Edge Review

BSN Syntha-6 Edge is BSN’s leaner version of Syntha-6 for those athletes and bodybuilders who are looking for the same great taste but with leaner macros. With a lower carbohydrate and fat content, and less calories, it’s amazing that it still tastes just as good!

BSN utilises exclusive flavour and mouth-feel technology to produce the most mouth-watering protein shake, it’s pretty much a milkshake. We put it to the real test. One of our staff members always complained she’d never found a protein powder she liked the taste of. BSN Syntha-6 Edge changed this. After one shake it is now her go to protein powder. Let’s take a closer look at this life-changing protein.

Macronutrient Information

A typical serving of BSN Syntha-6 Edge is about 40g and contains approximately 150 Calories, depending on the flavour. This is an average of 50 Calories less than the original Syntha-6 protein.

Each serve provides 24grams of protein, between 4.6g-6g carbohydrates with 1.1g-2g sugar, and about 3.5g of fat. This is a huge reduction of carbohydrates in comparison to the original Syntha-6, which contains 14g-15g.

BSN have successfully provided more of what bodybuilders and athletes want, and less of what they don't. More protein, less carbohydrates and fats. There have also been minor changes to the protein blend compared to the Syntha-6 blend.

Protein Sources and Ingredients

The protein matrix starts with a blend of whey protein concentrate and whey protein isolate. This is similar to Syntha-6, but most likely in a higher percentage of total protein ingredients to maximise protein and minimise fat and lactose. By using whey protein concentrate and isolate the protein blend provides both rapid and longer-term amino acid delivery. It also contains a high dose of naturally occurring branched chain aminos (BCAAs) to promote protein synthesis (muscle growth).

Next is micellar casein, also included in the original BSN Syntha-6 time release protein blend. Micellar casein is broken down by the body slower than whey protein concentrate and isolate. The slower digestion time provides a steady supply of amino acids for up to 8 hours after consuming the protein shake. This allows Syntha-6 Edge to support protein synthesis for a longer period of time. It also prevents muscle breakdown that can occur when your body doesn't receive enough nutrients. It provides greater versatility for the product as it can be used any time of day to help the body recover, rebuild and repair muscle tissue.

The first new addition to Syntha-6 Edge is milk protein concentrate, replacing Milk Protein Isolate. Milk Protein Concentrate contains all of the proteins naturally found in milk (approximately 80% casein and 20% whey) making it significantly different from whey protein concentrate. But the importance of Milk Protein Concentrate in this product is questionable as it already contains Whey Protein Concentrate and Isolate, and Micellar Casein. Aside from adding to the mixability, texture, there is little benefit to its inclusion. BSN would have been better to have kept egg albumen in the blend to provide a medium digesting protein source to bridge the gap between rapid digesting whey, and slow digesting casein.

But it is the second new addition to Syntha-6 Edge that is the game changer. Hydrolysed Whey Protein Isolate provides even more diversity to the original Syntha-6 protein matrix. Hydrolysed Whey Protein Isolate is the most highly processed of all whey proteins. It is pre-digested, so it is rapidly absorbed, making it the ideal protein source for pre or post workout. The inclusion of Hydrolysed Whey Protein Isolate serves to increase overall protein content without significantly raising the carb, fat or calorie content to keep BSN Syntha-6 Edge an ideal choice for dieting athletes and bodybuilders.

The remaining ingredients have taste and functionality purposes. Sunflower oil powder is a natural ‘anti-foam’ to reduce the froth produced when the protein blend is mixed with water. Flavourings, thickeners and sweeteners from sucralose and acesulfame-K round out the ingredients list of BSN Syntha-6 Edge.

Taste & Mixability

Anyone familiar with BSN knows they take their flavourings very seriousl. Syntha-6 Edge is no exception. There are 7 mouth-watering flavours including: Chocolate Milkshake, Chocolate Peanut Butter, Banana Milkshake, Cookies & Cream, Salted Caramel, Strawberry Milkshake & Vanilla Ice Cream.

Each BSN Syntha-6 Edge flavour mixes effortlessly using the recommended 120-150ml of water. 150ml of water per scoop provides a rich and smooth shake which is comparable to a milkshake or thickshake. While being thicker than most protein shakes, it is far from gluggy. In fact, the thickness is often a winning quality with customers who dislike thin, watery, shakes. The flavours are rich and creamy, with a sweet aroma that will fill the room and get everyone’s mouths watering. Salted Caramel is the perfect shake when you’re craving a “dessert” or “cheat meal”, while Banana and Chocolate are great for any time of the day.


BSN Syntha-6 Edge uses a high quality protein blend that helps to build muscle, recover faster and increase strength. Each scoop of Syntha-6 Edge delivers 24 grams of pure, quality protein from six quality milk based sources without a large amount of calories, carbs, fats or sugars.

BSN Syntha-6 Edge is the ideal choice for those wanting a leaner protein shake that still offers a full on taste experience and protein punch. With well rounded protein sources, BSN Syntha-6 Edge provides key nutritents for muscle building and recovery and makes hitting your daily protein target a tasty experience.

    12 Ways to Combat Stress, Sleep Better & Feel Amazing Every Day

    Greg Haglund, Switch Nutrition, 16 May 2022

    12 WAYS TO COMBAT STRESS, SLEEP BETTER & FEEL AMAZING EVERYDAY Stress affects us all. Some days it's worse than others, and over time, it takes its toll on how we look, feel and perform. Over 90% of adults say they experience stress or anxiety daily, and 74% say it's so great they feel unable to cope1. Add to this physical stress of training, injury, infection, or environmental toxins. Even certain foods can create stress on our bodily systems. Some acute stress is helpful. However, chronic stress can be very harmful - even deadly!! Here are ten things stress can cause and 12 ways to effectively combat stress: Reduced Thyroid Function Weight Gain Muscle Loss Gut Issues Lowered Sex Drive Skin Breakouts Hair Loss Low Energy Irritability & Loss of Empathy Sleep Disturbances How do we fix this? 1)      EXERCISE: Exercise is more effective in reducing stress, anxiety, and depression than the top 5 antidepressant medications 2. It might sound counterintuitive, but regular acute physical stress can significantly combat chronic mental stress. People who exercise regularly are less likely to experience anxiety and depression3. Exercise releases endorphins and gives you confidence which may help reduce your stress. During or immediately after training, be sure to use essential amino acids like AMINO SWITCH™ to accelerate recovery. AMINO SWITCH™ also contains the adaptogen Schisandra, which has been shown to increase energy and reduce stress. 2)      LAUGH: You've probably heard the term 'LAUGHTER IS THE BEST MEDICINE. Well, when it comes to stress, that is entirely true. When you have fun and laugh, it's hard to feel stressed. Laughing has a natural lowering effect on cortisol (stress hormones) and increases serotonin (happy hormone). It also activates the Vagus nerve, which helps transport the serotonin from your gut to your brain. One study showed laughing could help healing by activating the immune system, which could further reduce the effects of physical and emotional stress4. When we are stressed, it lowers our immunity which can result in increased inflammation and reduced recovery. Try watching comedies or hanging out with people who make you laugh and enjoy life. Once you start, it can become infectious. 😊 3)      SING: Like laughter, singing also boosts serotonin and activates the Vagus nerve. This has a relaxing effect and has been shown to reduce tension, stress, and anxiety. In one study, the music you enjoyed, because it brought back happy nostalgic memories, was the most effective at reducing stress markers. So next time you're in the car on your way to or from work, belt out a tune you love at the top of your voice and watch your stress levels drop. 4)      SPEND TIME WITH FRIENDS: People who live the longest, healthiest lives have two things in common: Purpose and community. Supporting friends and hanging out with friends and family can be stress-reducing. One study showed men and women with the least social connections had the most significant levels of anxiety and depression. However, pick your friends carefully and hang around people who support your goals and are genuinely fun to be around. 5)      SUPPLEMENT: Many natural ingredients can reduce stress. Here is a list of the top 7 and the supplements you can find them in - ·         Magnesium – ADRENAL SWITCH™ & ALPHA SWITCH™   This super important mineral is involved in over 600 bodily processes per day. It is critical for energy metabolism, nervous system relaxation, muscle recovery, energy, and so much more. Nearly 75% of the population is not getting enough magnesium for their daily needs. Simply supplementing with magnesium citrate after exercise or before bed will profoundly benefit your recovery and lower your cortisol (stress). ·         Ashwagandha – ADRENAL SWITCH™ & ALPHA SWITCH™ Known as the king of herbs. This Ayurvedic medicinal root has been used for centuries to help combat fatigue, reduce stress, and support energy. It is an adaptogen class of compounds that aid our mind and body adapt to stress. Ashwagandha contains a natural compound called Withanolides that have been shown to lower cortisol (stress) and support natural hormone balance. ·         Schisandra – AMINO SWITCH™ & ESTRO SWITCH™ This traditional Chinese medicinal berry supports qi (energy & life force). It elicits some of its benefits through liver detoxification. It is also an effective adaptogen (like ashwagandha) and improves how your body responds to caffeine by reducing jitters, improving energy levels and preventing an energy crash. Schisandra needs to provide high levels of Schisandrin A like that found in AMINO SWITCH™ & ESTRO SWITCH™. ·         Alpina galanga – COFFEE SWITCH™, THERMAL SWITCH™ & POWER SWITCH™ This unique alpine grown galangal extract has been shown to improve your tolerance to stress. It was voted 2019 innovative ingredient of the year and outperforms caffeine in focus and alertness scores without activating the central nervous system (without producing adrenaline or cortisol). Alpina galanga will often be found in combination with caffeine or coffee, as it has been shown to amplify your body's response to caffeine by 30 – 50% and make it feel cleaner & longer lasting.   Alpina may also reduce adenosine in the brain. Therefore, preventing mental fatigue, tiredness and procrastination. It also boosts D2 dopamine receptor sensitivity, which helps combat stress by boosting mood.   The feeling of Alpina and Caffeine together is one of happiness, alertness and profound focus. ·         Glycine – ADRENAL SWITCH™ & COLLAGEN SWITCH™ This non-essential amino acid has many benefits, including its tonifying effect on the nervous system. Glycine also helps support connective tissue recovery, immune response, and energy by supporting endogenous (internal) creatine production. Like GABA, it has a calming effect if used after exercise or before bed. However, Glycine can be consumed before training, where it can help improve energy. ·         L-Theanine – ADRENAL SWITCH™ L-Theanine is another non-essential amino acid with the ability to calm your body and brain. L-Theanine is found in green tea and has been shown to take the edge off caffeine (reduce jitters or anxiety) while promoting focus and elevating mood. ·         Medicinal Mushrooms – VITALITY SWITCH™ & COFFEE SWITCH™  Medicinal mushrooms have been used in traditional Chinese medicine and Ayurvedic medicine systems for centuries. They are adaptogens that help support your body's response to stress. They're also great at lowering inflammation which could be causing chronic physical stress. Medicinal mushrooms like Shitake, Maitake, Turkey Tail, King Trumpet and Cordyceps support energy and immunity while fighting pathogens like viruses, bacteria, fungus etc.   6)      GET YOUR MACROS & MICROS RIGHT: Undereating or eating calorie-dense but micronutrient depleted food can profoundly affect your mental health, stress, and body fat levels. Keep in mind 'FOOD CAN CHANGE YOUR MOOD'. Eating food that spikes and then drops your blood sugar levels can leave you exhausted, tired, grumpy, and hungry. Being in a chronic calorie deficit can increase cortisol (stress hormone), slow fat loss, increase muscle loss, and increase inflammation and stress. Make your diet cyclical and have higher calorie days mixed in with your calorie deficit. Using KETO SWITCH™ between meals or during fasting on your calorie deficit days can reduce muscle loss, support brain function, and reduce hunger. 7) MEDITATION & MINDFULNESS: We all know meditation and mindfulness are helpful ways of reducing stress. However, some people have difficulty clearing their minds when attempting meditation. Apps like 'Head Space' and others can teach you or guide you through meditation, which can be life-changing. 8) CUDDLE: Cuddling, hugging, kissing, and sex can relieve stress by promoting the release of oxytocin and serotonin. These practices have been shown to lower blood pressure, heart rate and other emotional and physical symptoms of stress. Chimpanzees also cuddle friends and family who are stressed, and it has the same hormonal response in our closest primate relatives. 9) YOGA & STRETCHING Yoga is an ancient Ayurvedic practice that has been shown to lower stress and anxiety for centuries. Studies looking at Yoga's overall effects have shown it to boost mood and lower stress. It may be as effective at treating depression as some medications. 10) BREATHE: Slowing your breathing helps to activate the parasympathetic (rest, digest, relax & recover) nervous system. It is the opposite of the fight or flight sympathetic nervous system, which is activated by shallow quick breaths.   If you get into anxiety or panic, try 'Box Breathing'. ·         Breathe in through your nose for 4 seconds. ·         Hold your breath for 4 seconds. ·         Exhale through your mouth for 4 seconds. ·         Hold the exhale for 4 seconds. ·         Repeat 4 times.   11)  GET A PET: Pets are like cuddling. They help us release oxytocin and serotonin. However, sometimes pets are even better because they generally provide unconditional love in return, and the relationships are not as complicated as human ones. Having a pet may also keep you active as you must exercise them daily, which is stress-relieving. 12)  GET OUT IN NATURE: Being in nature, surrounded by trees, mountains, lakes, streams or even on the beach, listening to the crashing waves is therapeutic and stress relieving. Part of the stress-relieving effect is due to our connection to the planet, and part of it is the disconnection from emails, social media and more which can increase stress. Another part is the sunlight on our skin boosts Vitamin D, endorphins and oxytocin, which have immune-boosting, hormone-regulating and stress relieving benefits. Disconnect at least once a week and exercise in nature (not just in the gym or around the block). Breathe in the fresh air and take in the calming effects being away from the city provides.   SUMMARY: There are so many stressors in our lives and multiple ways to help manage or destress. You need to consider what is stressing you the most and make efforts to remove these stressors from your life. If you practice all the above techniques but continue to expose yourself to a stressful job or relationship, it is like trying to put out a forest fire with a garden hose. It will help but may not prevent all the adverse effects of stress.

    5 Reasons Why You Need to Use Protein Powder for Protein Drinks

    Sportsfuel, 27 April 2017

    Juice bars might be the latest big thing. All your friends are going. There's one right next to the gym. But you don't have to stand in line for twenty minutes to get the best protein drinks out there. In fact, those "super smoothies" or "super juices" may be preventing you from reaching your goals rather than helping. Juice bar smoothies and drinks are often high in sugar. I can hear you thinking, but it comes from fruit. Yes, but you wouldn't eat the amount of fruit needed to make your juice in one sitting. And some of the fruits listed in the ingredients come from sugar-packed concentrates. Put the drink down and step away now. Plus, to really fuel your body to grow and repair muscles, you need to use protein powder. More juice bars are using protein powder in their drinks these days, but you're still better off to keep it simple and stick to quality whey protein without the unknown extras.Here, we're laying down the law when it comes to why adding protein powder to your protein drinks ensures you get the real nutrition your body needs. 1. Whey Protein Is High-Quality It's a fact: not all protein supplements and forms are created equal. Luckily, whey protein is packed with amino acids and is easy for your body to digest.The three main types of whey protein powder are concentrate, hydrolysate, and isolate. The most common type you'll see on the shelf is whey protein concentrate.All three types of powders are equally high in nutritional value. 2. It Can Increase The Antioxidants In Your Body It's not just a glass of red wine that's a great source of antioxidants - and protein shakes won't leave you feeling a little off the next day.Making sure you get enough antioxidants means that your oxidative stress levels are lower, meaning your body can easily fight off disease.Glutathione is found in whey protein, and it's a huge source of antioxidants. An added bonus? Glutathione can also help you to lose weight faster!What's not to love about that? 3. It Reduces Inflammation We've all been there: experiencing soreness after a killer workout that just won't go away. Did you know that chronic inflammation can even lead to disease?To combat this, consume protein drinks rich in whey powder, which can lower your body's levels of C-reactive protein: the very thing that generates inflammation.Prevent soreness and inflammation before it starts by drinking a protein shake before your next workout. 4. It Can Help To Lower Your Blood Pressure If you've got hypertension, you're at a higher risk for heart disease. Good news? Whey protein powder can help to lower your blood pressure.Why?Because whey proteins contain lactokinins, which are bio-peptides that can help keep your blood pressure at a safe level. It's equally effective for men and women. 5. It Helps Your Muscles To Grow Faster We all know you want to be bikini-ready in as little time as possible. Protein drinks can help. It's also a great preventative strategy when it comes to protecting the muscles you've worked hard to build.Since whey protein contains a lot of leucine, the most growth-stimulating amino acid, your muscles will build faster. You're An Expert In Protein Drinks! Now you know why adding whey powder to your protein drinks really makes a difference in healing and strengthening your body.For more information on the benefits of protein powder, vegan protein powders and mass gainers, and to learn where you can pick some up, check out our website and blog.
