Syntha 6 Protein Powder Review 2021 (Is This Supplement Any Good?)

Syntha 6 Protein PowderSyntha 6 is a highly popular protein powder that was made by BSN and given the name Syntha 6 due to the six different types of protein sources the blend is composed of. The common misconception is that more protein sources is a good thing, but in reality, more protein sources just leads to a dirtier blend that lacks purity.

Company Profile

BSN, along with Muscle Tech, does not have the best reputation as far as product performance goes in my eyes. They are a rather large company with several available products, none of which are note-worthy in my opinion with the exception of this particular product and their mass gainer.

Syntha 6 Ingredients

As mentioned above, this product contains 6 different sources of protein: whey protein isolate, whey protein concentrate, micellar casein, calcium caseinate, milk protein isolate, and egg albumin.

This is not an ideal protein blend. Don’t be fooled by companies that claim their product is better because it contains more sources of protein. More types of protein does NOT make it a better product. In fact, the blend should consist ONLY of whey protein isolate and/or whey protein hydrolysate in order for it to be ideal. Anything other than that, you are going to want to avoid.

One serving of Syntha 6 has over 200 calories and over 6 grams of fat (2 grams saturated fat). It also has 160 mg of sodium. This is certainly not the most nutritious protein powder.

In addition, Syntha 6 has 13 grams of carbs in one serving. Unless you’re looking at a gainer, you want to stay away from a protein powder that has a lot of carbs.

Syntha 6 Ingredients and Supplement Facts


Is it the best product out there? No, but it is certainly not the worst. It may be fairly effective as far as muscle gain goes, but there is a lot more that goes into this product than protein, and that is what’s important to look at.

There is a rather excessive amount of unhealthy ingredients in this product. With that said, I personally saw some results while taking it. At the time, I wasn’t aware of how unhealthy it was. I did notice an increase in muscle size, but I also noticed an increase in body fat. BSN claims this product helps you gain “lean muscle mass,” but I would beg to differ. It might help you gain mass, but I wouldn’t call it “lean muscle mass.” Remember, it has 6 grams of fat and 13 grams of carbs per serving.


A product with such a high sodium count (although its unhealthy) is highly unlikely to taste bad, and this one is no exception. The chocolate flavor specifically tastes excellent. It is one of the better tasting products I have tried. However, when it comes down to it, the taste is probably the least important factor. Also, the texture is slightly gritty, and not as creamy as it should be considering all of the creamers that go into it.

The Pros

  • Fairly low cost
  • Tastes great
  • Fairly effective

The Cons

  • Nutrition label tells an unpleasant story
  • Lots of unhealthy ingredients
  • Very high sodium, cholesterol, and carb count
  • Muscle gains may not be lean muscle mass
  • Using this product can cause you to gain fat in addition to muscle


Overall, this is a below average product. The unhealthy ingredients, high fat, high carbs and the inferior protein blend really bring the rating down. There’s no way we could recommend Syntha 6 to our readers after examining the SFP (Supplement Facts Panel). It’s all bad news here, but the biggest downfall lies within the protein blend itself.
