Yum! Love the choc chips in the cookie dough flavour! Mixes really well and tastes great with milk or water. Winning!

Hands down the best tasting protein on the market. Tastes creamy even mixed with water. Plus being able to take it anytime of day because of the different types of protein is great.

Syntha-6 Protein Powder Banner


This premium product from BSN has been well known within the sports nutrition industry for decades as the best tasting protein powder. It mixes to a smooth semi-thick consistency and tastes just like a quality milkshake from cafe. As far as taste, texture and overall palatability is concerned, BSN Syntha-6 is unbeatable.


BSN Syntha-6 Protein Overview

Syntha-6 is a great protein supplement if you are looking for lean muscle gains. Due to its protein profile it will also make an ideal meal replacement due to its fast and slow protein sources which aid satiety and control appetite. Due to its amazing taste, BSN Syntha-6 helps to alleviate sweet cravings and its thick consistency makes it filling to control appetite for hours.


This protein powder comes in a range of delicious gourmet flavours, including banana, chocolate, cookies and cream and vanilla. Syntha-6 offers a premium protein for those customers who love a great-tasting protein shake. We thought all the flavours were awesome, though really got quite addicted to chocolate, as well as cookies and cream. In fact, half and half of these 2 flavours mixed with ice-cold full cream milk makes a nice choc cookie shake. Just be warned, it's addictive!

There are so many different proteins out there, even within the BSN and ON range (both owned by Glanbia). Let's take a quick look at the differences between the original Syntha-6, Isolate, Edge and Optimum Nutrition Gold Standard Whey Protein.


Syntha-6 as the name suggests delivers 6 quality protein sources (WPC, WPI, calcium caseinate, micellar casein milk protein isolate and egg albumin) covering fast, medium and slow digestion rates. It delivers 22g protein per serve with 15g carbohydrates. BSN Syntha-6 delivers 10g of naturally occurring EAAs per serve at a cost of only 200 calories per serve.


BSN Syntha-6 Isolate on the other hand offers a protein matrix of WPI and Milk Protein Isolate. This is still a variable fast and slow absorption rate, yet with half the carbohydrates, 11g EAA’s and 140 calories per serve. One thing that stays true to both products is the amazing taste throughout the range. However, the standard Syntha-6 does win first place for flavour.


There are several differences between Syntha-6 and ON Gold Standard Whey Protein. Gold Standard Whey provides predominantly WPI with a small amount of WPC, making it a fast to medium absorbing protein compared to the slow absorption rate of Syntha-6. ON Gold Standard delivers a slightly higher 24g protein per serve with less carbs at only 3g. ON Gold Standard has more flavour options and mixes to a more fluid consistency due to the fact that it does not contain the ticker casein protein.


Edge is the newest addition to the BSN range and differs to the original product by providing less calories, carbohydrates and fat. Providing 24g protein from 6 different protein sources, Syntha-6 Edge provides a leaner version of BSN Syntha-6 to aid recovery and muscle growth.


BSN Syntha-6 Side Effects?

This product has no known side effects other than an addiction to its amazing taste. Like any supplement you should always check the ingredients for any known allergens. As Syntha-6 contains dairy proteins, it may upset those with a lactose intolerance or dairy allergies.


How to Use BSN Syntha-6
Males - Take 1-2 scoops with 250 - 350ml of water. Drink 1-2 serves daily or as needed to satisfy your protein or muscle enhancing requirements.
Females - Take 1 scoop with 200-300ml of water. Drink 1-2 serves daily to satisfy your protein or body shaping requirements.
