Available from November 2015, BSN Syntha-6 Edge utilises BSN’s exclusive flavour & mouth-feel technology to produce the most mouth-watering protein shake imaginable.

At first glance BSN Syntha-6 Edge looks to shake up the premium protein blend category, going toe-to-toe with the likes of Jym Supplement Science Pro JYM, International Protein Synergy 5 and Cellucor Whey, some of the most popular blended protein powders on the market.

Nutritional Information

BSN have taken their time to deliver the latest extension to the Syntha-6 product line, promising a blended protein powder that delivers the best taste and texture in its class. BSN Syntha-6 Edge delivers the protein bodybuilders and athletes desire without the added calories, carbohydrates & fats.


The BSN Syntha-6 Edge range for Australia and New Zealand has been confirmed in three sizes, namely; 26 Serves, 45 Serves and 100 Serves, with the 100 Serves Bag reflecting the best value for money.

A typical serving size of BSN Syntha-6 Edge is 37g-40g containing between 150 Calories (627kJ) to 156 Calories (654kJ), depending on the flavour. For the calorie conscious bodybuilder BSN Syntha-6 Edge boasts on average 50 calories (209kJ) less than the traditional Syntha-6 protein powder. 

The macronutrient breakdown provides 24 grams of protein across all flavours, a carbohydrate range of 4.6g – 6g, of which 1.1g – 2g are sugars, and between 3.5g – 3.7g of fat per serving. In comparison to the traditional Syntha-6, BSN Syntha-6 Edge has more than 60% less carbohydrates. Interestingly the sugar content in BSN Syntha-6 Edge is of a higher percentage of total carbohydrates (30%) compared to that of traditional Syntha-6 (13%) due to the reduction of dietary fibre and complex carbohydrates.

As can be seen in the details above BSN Syntha-6 Edge successfully provides more protein, less carbohydrates, less fat, and less calories overall than its predecessor. Syntha-6 Edge also sees some minor alterations to its protein blend in comparison to the original Syntha-6 protein matrix.

The BSN Syntha-6 Edge protein matrix begins with a blend of whey protein concentrate (WPC) and whey protein isolate (WPI), similar to the traditional Syntha-6, but most likely in a higher percentage of total protein ingredients to ensure fat and lactose are minimised. The combination of WPC & WPI provides both rapid and longer-term amino acid delivery, plus a high dose of naturally occurring BCAAs (Branch Chain Amino Acids) to maximize protein synthesis and the immune boosting benefits of naturally occurring biological compounds.

Next is the inclusion of micellar casein which also featured in the original BSN Syntha-6 staggered release protein blend. Micellar casein is broken down very slowly by the body as it creates micelles (small "gooey" clumps) in the stomach to provide a slow and steady supply of amino acids for up to 8 hours after ingestion. The micellar casein in Syntha-6 Edge therefore works to keep protein synthesis extended for longer and decrease muscle protein breakdown, whilst providing greater versatility to the consumer by delivering a product that helps you recover, rebuild and repair muscle tissue any time of the day.   

The first new protein addition to Syntha-6 Edge is milk protein concentrate (MPC) essentially replacing Milk Protein Isolate (MPI) in the original Syntha-6 formula. Despite what many believe, MPC is significantly different from WPC in isolation as it contains all of the proteins that are naturally found in milk (comprising of approximately 80% casein and 20% whey).

With the inclusion of WPC, WPI and micellar casein protein, the importance of MPC in Syntha-6 Edge is questionable. Beyond adding to mixability, texture, and providing the 6th milk based form of protein, it actually seems rather redundant. It would perhaps have been more beneficial for Syntha-6 Edge to continue using egg albumen like its predecessor to provide a medium digesting protein source that bridges the gap in digestion timing between whey and casein.

In contrast, hydrolysed whey protein isolate (HWPI) is the BIG game changer for Syntha-6 Edge, providing even more diversity to the Syntha-6 protein matrix. Hydrolysed WPI is the most highly processed of all whey proteins and is pre-digested resulting in rapid absorption, making it the ideal protein for pre and post workout use. The inclusion of hydrolysed WPI in Syntha-6 Edge works to increase the overall protein content per serve without significantly increasing the carbohydrate, fat or calorie content, making BSN Syntha-6 Edge an ideal choice for dieting athletes.

The remainder of the ingredients in BSN Syntha-6 Edge are essentially added for taste and functionality rather than their nutritional properties. Sunflower oil powder works as a natural ‘anti-foam’ to help reduce the froth produced by the protein blend when mixed with water. Flavourings, thickeners and sweeteners from sucralose and acesulfame-K make up the remainder of the ingredients in BSN Syntha-6 Edge.   

Taste & Mixability

Anyone familiar with BSN knows they take their flavourings very seriously across all their bodybuilding and fitness supplements. Syntha-6 Edge is no exception, offering 7 exceptional flavours including: Chocolate Milkshake, Chocolate Peanut Butter, Banana Milkshake, Cookies & Cream, Salted Caramel, Strawberry Milkshake & Vanilla Ice Cream. No doubt there will be more flavours released in future as Syntha-6 Edge grows in popularity.

Each BSN Syntha-6 Edge flavour mixes effortlessly in a very small amount of water (just 150ml per scoop is more than enough) resulting in a rich & smooth shake with perfect thickness without being overly gluggy to drink. All flavours are very impressive and consumers can expect an overwhelming creamy taste followed by rich sweet aromas.


BSN Syntha-6 Edge uses a high quality protein blend that helps to build muscle, recover faster and boost strength. Each scoop of Syntha-6 Edge delivers 24 grams of pure, quality protein from 100% milk based sources that is not ‘spiked’ with single amino acids or made with inferior protein sources.

BSN Syntha-6 Edge is a product that should be at the top of everyone’s supplement shopping list. Syntha-6 Edge offers a well rounded protein source, providing key nutrients for muscle growth encapsulated into one of the most delicious, smooth milkshake-like experiences seen in a protein powder supplement.
