BSN’s original Syntha-6, which is still available, is one of the most popular protein supplements around. Every flavor was rich, thick and tasted delicious. The only concenrn I had when taking Syntha-6 was it’s carb and fat content. When your diet is dialed in, every gram of carbs and fat counts. For a whey protein blend, Syntha-6 was ridiculously good. So when I heard that BSN was going to release Syntha-6 Isolate I was crossing my fingers that they could somehow manage to keep the great taste while reducing the carbs, fat and calories AND deliver pure whey protein isolate. How did they do? Let’s take a quick look at BSN’s Syntha-6 Isolate…

What is BSN Syntha-6 Isolate?

Syntha-6 Isolate is BSN’s ‘ultra-premium’ protein powder made from 100% isolate sources. [1] Syntha-6 Isolate is made up of a 50/50 blend of whey protein isolate and milk protein isolate. Syntha-6 Isolate has 25 grams of protein per serving, 1.5g of fat and 7g of carbs which gives us a total of 140 calories per serving. This is a huge improvement over the ‘original’ Syntha-6 which has 22g of protein, 6g of fat, 13g of carbs for a total of 190 calories per serving. You do pay a little more for Syntha-6 Isolate, but it is a much better supplement.

Syntha-6 Isolate Ingredients

Syntha-6 Isolate contains two different protein sources – whey protein isolate and milk protein isolate.

Whey Protein Isolate – Whey Protein Isolates contain more than 90% protein with virtually no fat and no lactose. Isolate is a good “in between meal” protein powder. It is absorbed slower than the higher quality Hydrosylates, which are found in products like BaddAss Surge or Optimum Nutrition HydroWhey.

Milk Protein Isolate – Milk Protein Isolate (MPI) is a slow-digesting protein that is derived from milk proteins. MPI is a casein/whey mixture (80% casein, 20% whey). Because it is digested slower than whey protein isolate, it provides a constant stream of amino acids to the bloodstream compared to whey.

I read about one study looked at the effect casein has on body composition when used as part of a 12-week weight-training program. Participants were separated into two groups, each of which maintained a balanced diet including 75 grams of protein per day. The difference was in the sources of protein used: while the first group relied on whey-based drinks to reach their daily protein requirements, the second group made use of milk protein isolates (80% casein, 20% whey). At the end of the study, the milk protein isolate group had lost more fat (15.4 lbs. vs. 9.2 lbs.), gained more lean mass (9 lbs. vs. 4.4 lbs.), and gained more upper and lower body strength than the whey group.

Syntha-6 Isolate Serving Size and Flavors

Syntha-6 Isolate is available in three different sizes and three different flavors. There is Chocolate Milkshake, Strawberry Milkshake and Vanilla Ice Cream.

You can buy these flavors in a 48 serving 4 pound container, a 24 serving 2 pound container or a 7 serving 9 ounce container. Each serving of Syntha-6 Isolate will cost you anywhere from $1.15 to $1.50. This is on the high end for a protein powder, especially when you consider that it is a whey and milk protein isolate blend. To give you a better comparison, last week I reviewed ProSupps TC-F Isolate which costs $0.80-$0.90 per serving. I spend a Sh%$ ton of cash on protein just because I use so much of it. So when I am budgeting out my monthly supplement spend, I’d rather get my best bang for the buck.

Syntha-6 Isolate Final Thoughts

Syntha-6 Isolate is a great tasting protein powder that contains a unique blend of fast and slow digesting proteins. There is very little lactose when compared to the original Syntha-6 and its nutritional values seem much better. Syntha-6 Isolate is a HUGE improvement over BSN’s original protein powder. If taste is what you are looking for, you won’t be disappointed!
