BSN Syntha-6 review


My primary protein supplement has always been whey isolate but I have recently added a meal replacement protein (MRP) supplement into my arsenal because of their versatility. I wanted to try out a new MRP so I picked up a couple of 2.91lbs BSN Syntha-6 a few weeks ago and have been taking it on a daily basis ever since. Here is my BSN Syntha-6 review.

Ingredient Profile – 7/10BSN Syntha 6 review   reviews

Syntha-6 uses 6 types of protein in their matrix. Unfortunately with blends, you never quite know how much of each type of protein you are really consuming. The first one listed is always the most abundant, so in decreasing order the proteins included are whey protein concentrate, whey protein isolate, calcium caseinate, micellar casein, milk protein isolate and egg albumen. BSN has also included extra glutamine peptides in their formula. Following the protein matrix on the list of ingredients is Sunflower Powder, which has corn syrup solids as one of its components. The other main contributor to the Syntha-6 formula is MCT Powder. The ingredients round off with a couple of digestive enzymes, papain and bromelian.

I compared the nutrition facts on my container to those on the BSN website for the same flavour and there are some discrepancies, even after taking into account the slight difference in suggested serving size (which I also thought was strange). Other than a couple of switches in ingredient order, the only difference in actual ingredients was added salt in the one online.

Looking at the nutrition facts online, the cholesterol, sodium and potassium actually vary significantly among flavours. The other nutrients stay somewhat consistent at 190-200 calories, 6g fat (2g saturated), 13-15g carbohydrates (3-5g fiber, 2-4g sugar), and 22g protein per serving.


BSN Syntha-6 mixes up fairly easily with water in just a simple shaker cup, no shaker ball necessary. One of the flavours I tried is cookies and cream and it actually has little bits of cookie in it. I’m not a huge fan of that.


I had cookies and cream as well as chocolate mint. Outstanding flavours! I can easily say these are 2 of the best tasting proteins I have ever had, and I have tried a ton of proteins. If you’re not super picky about ingredients or the nutrition facts, and just want a great tasting protein supplement or MRP, you must try Syntha-6.


When I used Syntha-6 as a MRP it worked well. The different proteins did their own thing and kept feeding me for a couple of hours. The fiber also really helped in keeping me full until my next meal. I also used Syntha-6 before some workouts if timing was off and I couldn’t get in a proper food meal. It worked really well then too since it kept my body fueled and kept my strength up throughout my workout. The other main time that I used Syntha-6 was before bed. If I had a late workout followed by a lighter than usual dinner, I also had Syntha-6 to keep my muscles fed and to help with recovery while I slept. I didn’t use Syntha-6 post-workout. For that time, I really like to stick to a pure whey isolate. For my purposes, as a snack or a MRP, Syntha-6 worked quite well. I didn’t notice any gains (not my goal) but I stayed nice and lean. I do have to mention that on occasion I had a bit of an upset stomach. Could be due to one of the proteins, or maybe from the corn syrup solids.


If you choose your protein or MRP based on taste, BSN Syntha-6 is a no-brainer. It’s also great how versatile this supplement is. You can use it as a MRP or a snack, post-workout, or just before bed. However, compared to other MRP I’ve had before, the nutrition profile isn’t the greatest. I find it a little high in calories, fats and carbs, while a little low in protein. Another negative in my opinion would be the price. It’s pricier than other options that are as good for you, if not better.
