BSN Syntha-6 ? Analysis

O Syntha-6 is a protein supplement from the BSN brand, and, contrary to the analyzes we have been doing, it is not just a whey supplement, but a product with a mixture of various proteins.

We will use the nutritional values of the cold vanilla flavor to make this review, as they change slightly between aromas.

In addition to the cold vanilla flavor, Syntha-6 is available in various flavors such as strawberry, banana, wafer / cream and chocolate shake.

As already mentioned, this product is not just a whey protein supplement, but a mixture of several proteins, as we can see in the list of ingredients below.


syntha ingredients 6

The ingredients are organized by percentage of use, that is, the first are the ones that exist in greater quantity in the supplement.

Knowing this, we look at the list of ingredients and the proteins that are most present in order are:

  • Concentrated whey, the most common form found in protein supplements.
  • Isolated whey, a superior form of whey, of high quality and fast absorption.
  • Calcium caseinate, a form of casein.
  • Micellar casein, an extremely slow-absorbing protein source extracted from milk, a form of casein superior to calcium caseinate.
  • Protein isolated from milk, this is a mixture in itself composed of whey and casein, as found in milk but without fats and sugars.

Finally, we have albumin, which is the egg protein, which is of good quality and we can classify it as intermediate absorption and also glutamine peptides, which as the last ingredient, the doses will be minimal.

We already know which proteins are used, but isn't the list of ingredients half way through yet? so let's sum up the rest.

Polydextrose is a sweetener, rich in fiber and low in calories.

Soy lecithin is high in fat.

Then we have ingredients like sunflower oil and corn syrup, which help with the flavor, but harm the rest.

We also have a small amount of MCT's, which are fats that can play an interesting role in fat loss.

And finally, flavorings and sweeteners (more).

Ingredients presented, let's move on to the nutritional value of BSN Syntha 6.

Nutritional value

We already know that the Syntha-6 it is a mixture of several proteins, and we already know the list of ingredients in more detail, that is, it is time to know now the nutritional values of this supplement.

The values shown are those of the vanilla ice cream version, European version.


The first table refers to a dose of this supplement, that is, 48 grams, which is the number presented by the brand.

The second table is the values for each 100 grams of product.

BSN's Syntha-6 is a protein supplement with a protein content of 45%.

Is this bad?

No, this is not bad, this is terrible, this protein supplement is not even half protein.

Then, looking at the table, Syntha-6 consists of 20% of carbohydrates and 12% of fats.

We criticized the MusclePharm's Iron Whey for having 18% of carbohydrates, and now we have a new sugar champion? Syntha-6.

In addition, 12 grams of fat is too high.

Let's put these values face to face with two proteins, the Scitec Whey Professional and the Myprotein Impact Whey.

Is it fair to compare a supplement made up of a mixture of various proteins to supplements made exclusively from whey?

Maybe not, but it's also not fair to sell a theoretically premium protein supplement with a miserable 45% protein content.


The ingredients we already know, the (bad) nutritional value too, now the price remains.

Values are always subject to change, but we used approximate values and within the average of what is found in online stores.

Cost Per Serving1.14 ?0.97 ?
Total cost31.00?47.00?

This supplement is available in two main formats as we can see from the table, the smallest with 1.3 kg and the largest with 2.2 kg.

In the smaller version, each shake costs 1.14€, while in the larger version the price drops to 0.97€.

This means that we will pay between 1.14? at 0.97? per ?22g of protein.

What about this value?

While it's not 100% fair to compare exclusively whey proteins to blends, let's do it to put the price of Syntha-6 in perspective.

Syntha-6 2.2kgProfessional Whey 2,3kgImpact Whey 2.5kg
Cost Per Serving0.97 ?0.67 ?0.31 ?
Total cost47.00?53.00?30.89 ?

Professional Whey has a protein content of 73%.

Impact Whey has a protein content of 82%.

Syntha-6 has a protein content of 45%.

Therefore, the weakest supplement is also the one with the fewest doses, the most expensive per dose and the second most expensive in the total cost.

BSN Syntha-6


O Syntha-6 is a supplement composed of several proteins, which can be interesting to use in meals other than post-workout.

However, a protein supplement that has a protein content of only 45% is terrible, however interesting the protein sources are.

A very low amount of protein, very high carbohydrate values, too many fats and a high price considering what it offers us.

Who can we recommend this protein to?

To nobody.
