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 several proteins.

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

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

As we have 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 6 ingredients

The ingredients are organized by percentage of use, that is, the first ones are those that exist in the greatest 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 rapid absorption.
  • Calcium caseinate, a form of casein.
  • Micellar casein, an extremely slow-absorbing source of protein, extracted from milk, a form of casein superior to calcium caseinate.
  • Protein isolated from milk, this is a mixture made up of whey and casein, just like we find in milk but without the fats and sugars.

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

We already know which proteins are used, but the list of ingredients isn't even halfway through... let's summarize the rest.

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

Soy lecithin is rich in fat.

Then we have ingredients like sunflower oil and corn syrup, which help with the flavor, but detract from 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, meaning it is time to find out the nutritional values of this supplement now.

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

48g 100g
Proteins 22g 45.83g
Carbohydrates 10g 20.83g
Fats 6g 12.50g


The first table refers to one 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 is made up of 20% of carbohydrates and 12% of fats.

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

Furthermore, 12 grams of fat is too high.

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

Syntha-6 Impact Whey Scitec Whey
Proteins 45.83g 82g 73.3g
Carbohydrates 20.83g 6g 7g
Fats 12.50g 6.8g 5.67g


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

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


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

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

1300g 2270g
Doses 27 48
Cost per dose 1.14? 0.97?
Total cost 31.00? 47.00?


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

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

Does this mean we will pay between 1.14? to 0.97? per…22g of protein.

What to say about this value?

While it's not fair to compare all-whey proteins to blends, we'll do so to put Syntha-6's price into perspective.

Syntha-6 2.2kg Professional Whey 2.3kg Impact Whey 2.5kg
Doses 48 78 100
Cost per dose 0.97? 0.67? 0.31 ?
Total cost 47.00? 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 total cost.

Where to buy?

You can find this supplement available here and you can still use the code GVIRTUAL to get a discount.

It is also available on Body&Fit.

BSN Syntha-6


O Syntha-6 It is a supplement made up of several proteins, which may be interesting to use in meals other than post-workout.

However, a protein supplement that only has a protein content of 45% is terrible, no matter how interesting the protein sources are.

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

Who can we recommend this protein to?

To nobody.
