Supplement Superstore Reviews: BSN Syntha-6 Protein Powder Review

We’re back again with another Supplement Superstore Review, and we’re talking about an amazing product you’re sure to have wondered about. BSN, short for Bio-Engineered Supplements and Nutrition, Inc., has one of the most recognizable and popular protein powder products to date—BSN Syntha-6 Ultra-Premium Protein Matrix.

Read on to find out how BSN Syntha-6 stacks up.

BSN Syntha-6 Protein Powder

BSN Syntha-6 is a superior quality protein powder that utilizes a unique protein matrix to deliver a great taste and a power punch of nutrients for those looking to increase their daily protein consumption.

The protein powder matrix consists of:

BSN Syntha-6, Strawberry Milkshake
  • whey protein concentrate
  • whey protein isolate
  • calcium caseinate
  • micellar casein
  • milk protein isolate
  • egg albumin 

Each serving of protein powder contains:

  • 6 grams of fat
  • 15 grams of carbs
  • 22 grams of protein 

Other nutritional facts to note are that the formula contains only 2-4 grams of sugar (depending on the flavour) and more fibre than the typical protein powder. This protein supplement also includes 10 grams of essential amino acids per serving.

Why Whey Protein Powder?

We like whey protein as a staple supplement across the board. Whether your goals are to gain muscle or lose weight, we believe you can most likely benefit from whey protein powder.

Whey protein powder is generally the go-to recommendation for those who have decided to supplement their protein intake. This holds true unless you have a dietary restriction, be it allergies or preferences.

Once you decide on whey protein powder, the next step is typically determining whether you will benefit the most from a concentrate, isolate, or something else. In general, the different forms of whey protein powders each have pros and cons. The good thing about BSN Syntha-6 is that the protein formula is a matrix containing many of the different forms.

In this way, BSN Syntha-6 is a dynamic protein powder with more nutritional value than an isolate alone, if that’s what you’re looking for nutritionally speaking.

More About That Protein Matrix

If you’ve read our content, you know we love whey protein for its ease of digestion and speed of absorption for the post-workout period. We also frequently advocate for the use of micellar casein in addition to your post-workout shake. Using casein for times like before bed or as a meal replacement can be beneficial.

This is because micellar casein is much slower to digest, allowing the level of amino acids to be slowly delivered for hours on end, repairing muscle tissues. So, the result of the dual-use could mean better, faster results for some people.

Within the protein matrix in Syntha-6, you’ve got both quick digesting whey and slow-moving casein. This combination allows you to get the benefit of both proteins all in one product. It’s ingenious, and among other things, this protein shake will sustain your hunger for longer without making you feel overly full or heavy. 

Shop Protein Powders


Now, to the specifics. Every protein supplement claims to be the best tasting on the market. In general, whey protein has come a long way from having a nasty aftertaste and unmistakable protein flavour, but BSN Syntha-6 truly still comes in at the top. 

This product is available in flavours like:

BSN Syntha-6, Chocolate Milkshake
  • chocolate milkshake
  • chocolate cake batter
  • vanilla ice cream
  • strawberry milkshake
  • banana
  • cookies and cream
  • chocolate peanut butter

BSN Syntha-6 really does taste like a dessert, and you wouldn’t be the first person to drink it as a sweet replacement.


The suggested use is to mix one serving of BSN Syntha-6 with 4-5 ounces of water, and even with such little liquid, the shake is extremely thin, albeit as smooth as you’d expect (as long as you’re using a blender bottle or a blender).

To amp up the nutrition and the experience, you can mix with milk instead of water, and the texture is a little thicker and flavour creamier. 

Overall Rank

Overall, we’re happy to score BSN Syntha-6 with a 9 out of 10. The texture and flavour are stellar, and we like the protein matrix for a diverse protein powder.

The ding in ranking comes from a factor we haven’t discussed yet: the number of ingredients and the use of artificial sweeteners and flavours. While still within the normal range as far as protein supplements, we do prefer to see natural sweeteners utilized and a condensed ingredients list.

Do Customers Agree?

In this case, our customers might rank this product a little higher than we do, giving it a 10 out of 10. People love the flavour and comment that they use it to satisfy cravings for sweets.

We’ve also received lots of feedback about how this product fills you up and holds you over between meals for much longer than a standard whey protein isolate. 

Who is BSN?

Born in 2001, BSN has risen to leadership status in the sports supplement industry. Their innovative and cutting-edge products serve everyone from hardcore athletes to average Joes and everyone in between.

Both the product line and the brand have won numerous awards since their founding, and they’ve built a loyal band of customers and a widely recognizable look.

Other BSN Products to Try

Besides giving BSN Syntha-6 a try, you will be interested in trying N.O.-Xplode, too.

BSN N.O.-Xplode

This is a pre-workout product that contains not only 275 mg of caffeine and beta-alanine to support focus and performance, but it also contains an impressive blend of vitamins and minerals, including:

BSN N.O.-Xplode Pre-Workout, Fruit Punch
  • vitamin D
  • thiamin
  • niacin
  • vitamin B6
  • vitamin B12
  • phosphorous
  • magnesium
  • potassium

We’re impressed with the inclusion of electrolytes to support hydration and think that this pre-workout formula contains everything you need to have your body prepared and your mind energized for an excellent workout.

Shop Pre-Workout Supplements

All in all, BSN is one of our most recognizable sports supplement brands, and BSN Syntha-6 is a solid contender for our top protein powder products. So, if you give them a try, sample both the protein powder and the pre-workout supplement!
