Syntha-6 by BSN Review – Should You Try This Protein Powder?

What Is Syntha-6?

Syntha-6 is a new protein shake that delivers all the benefits of your favorite whey protein – and then packs some benefits atop that. This protein powder provides 22 grams of protein per serving, but it doesn’t stop there. It also offers a high fiber content, is fairly low in carbohydrates, and is not high in fat.

Moreover, many users of whey protein powders don’t like the taste. But this supplement comes equipped with exclusive flavor technology that make it one of the best-tasting protein shakes out there. It comes in nine flavors, so you’re sure to find one that works. It also comes with 10 grams of essential amino acids per serving, making it a complete protein, and you can buy it in a variety of sizes to save money and shipping costs.

Whether you want to build up muscle, drop fat, improve cardiovascular fitness, get stronger, or all of the above, a good protein supplement is key to rebuilding damaged muscle fibers so you get stronger, bigger muscles. But not all whey proteins are created equal. That’s why Syntha-6 is an unparalleled choice for when you need to provide your muscles with quality fuel.



Syntha-6 is manufactured by BSN (Bio-engineered Supplements and Nutrition), a company that has been creating quality sports nutrition products since 2001. BSN and its products have won more than 35 of the sports nutrition industry’s awards since the company came to be, and BSN is used and endorsed by many celebrity athletes and fitness personalities, including UFC title holder Conor McGregor and multiple IFBB (International Federation of Bodybuilding and Fitness) competitors. BSN manufactures a stack of products that it recommends using alongside this one. This stack includes a nitric oxide pre-workout supplement and a recovery supplement to help you along at all stages of training.


How Syntha-6 Works?

When you train – whether it’s a long run or a strength session – muscle fibers break down, and the body repairs them. In order to adequately heal muscle fibers, your body needs to have enough extra protein, which is taken in nutritionally. These protein molecules are used to heal the broken muscle fibers, and the healed fibers are bigger and stronger than the ones that were there previously.

Making sure you have enough dietary protein is especially important, and behind that fact is the concept of nitrogen balance. Proteins are distinct from fats and carbohydrates – the other two macronutrients – because they have a nitrogen molecule, so the best way to measure adequate intake is the ratio between nitrogen taken in and nitrogen excreted.

When you want to build muscle, a positive nitrogen balance is ideal. This is when you take in more nitrogen than you excrete, meaning that your body has surplus nitrogen. This surplus is used to rebuild muscle fibers and build additional muscle. A negative nitrogen balance – when you excrete more nitrogen than you take in – is dangerous. If your body is in this state, muscle fiber will actually break down in order to supply your body with the nitrogen it needs for other processes. This nitrogen will ultimately be excreted as a waste product.

While you may be able to get all the protein you need from diet, supplementing with this product can help you make sure you get more than enough protein. But not all protein is equal. Amino acids are the building blocks of proteins. Some of them are made by the body, but there are nine of them – known as essential amino acids – that must be obtained from food. In order to be at your optimal health and build muscle to your full capacity, it’s necessary to make sure you get all these amino acids from food. It contains all of these essential amino acids, and there are a full ten grams of them per serving. This ensures that you’ll have plenty of these essential aminos and thus build muscle to your maximum potential. Of course, it’s still important to eat regular meals that contain protein, but this supplement can help ensure that you get protein from a variety of different sources and thus eat a variety of different amino acids.

Many athletes consider whey protein an indispensable part of their training and nutrition regimen, and this product contains no caffeine or other stimulants, so it can be taken at any time of day pr night. It is worth noting that most experts recommend taking protein supplements immediately after exercise, as this is when the body most needs additional protein to rebuild muscle tissue. When you take Syntha-6, you get all the essential amino acids and high-quality protein to nourish muscle tissue for maximum performance, great recovery, and of course reduced soreness.


Ingredients of Syntha-6

As a dietary supplement, this product adds plenty of protein for not a lot of calories. In a scoop, which is one serving, you’ll get 200 calories. A serving has six grams of fat, 14 grams of carbohydrate, and five grams of fiber. As most anyone knows, fiber is an important part of the diet. It helps with digestion and keeping you feeling fuller – which can help if you’re trying to cut down on body fat.

Syntha-6 also contains electrolytes sodium, potassium, and magnesium, which can help to replenish your body after a grueling workout and prime you for your next one. Of course, the first and central ingredient is a protein matrix. Unlike many whey protein powders that only contain one type of protein (usually whey protein isolate), the protein matrix contains whey protein concentrate, whey protein isolate, calcium caseinate, micellar casein, milk protein isolate, egg albumin (egg whites), and glutamine peptides (protein molecules). This variety of protein sources ensures that you’ll be supplied with a more effective protein blend.

To the uninitiated, the ingredient list of the protein matrix may sound repetitive. After all, these are all different types of protein. But there are important differences between them. One of the most important differences to note is the difference between whey protein concentrate and whey protein isolate. Some experts argue that whey concentrate is superior to whey isolate, and this claim is a bit difficult to prove or disprove, as the vast majority of studies on protein supplementation have been done using whey isolate. However, whey concentrate can be considered a whole food in the sense that it does contain lactose in trace amounts. It also contains the fatty acid conjugated linoleic acid, which tacks on some additional health benefits. Whey concentrate may have a few more health benefits as opposed to whey isolate, but this supplement contains both, so you get the best of both worlds.

Syntha-6 contains two types of casein protein. You may think that this is simply another protein, identical to whey. However, newer studies are beginning to illustrate the fact that casein protein has additional benefits. For instance, if you are operating at a calorie deficit – as many of us are when we’re trying to lose extra fat – taking casein protein with your whey can help promote muscle retention. None of us want to lose muscle when we’re trying to lose fat, and the addition of casein protein to your regular whey protein can help guard against this unpleasant phenomenon. Additionally, because casein protein tends to have a higher calcium content, it can actually aid in fat loss.

Egg white protein has the added benefit of being lower in carbohydrates, so its inclusion lowers the total carbohydrate content of your supplement. Plus, egg whites (especially those from pastured chickens) have higher levels of vitamins A, B, and D. This adds some extra nutritional punch to this already-powerful supplement. This supplement sets itself apart from the competition because its protein matrix has so many different types of protein. You get the most complete protein available, and it becomes easier to lose fat while building muscle.

If you have allergies, though, you should be aware that this product contains milk, wheat, egg, and soy ingredients.



Syntha-6 is a protein supplement that comes with a plethora of advantages. To start, its variety of protein sources makes it a more complete source of protein than many supplements. Most of the cheaper protein supplements only contain whey protein isolate. The isolate works ok, but when paired with whey protein concentrate and other protein sources, it has much more impact when it comes to building strength, stamina, and muscle.

Another advantage is the fact that this supplement contains fiber and electrolytes. These added ingredients make it much more nutritionally complete compared to other protein sources. And of course, the fact that Syntha-6 is one of the best-tasting protein supplements available is advantageous. When taking your protein is a treat as opposed to a chore, you’ll be much more likely to actually want to take it on a regular basis.

This product packs in a good bit of protein in a serving that is only 200 calories, six grams of fat, and nine net carbohydrates. This is important, as some protein supplements are high in carbohydrates or fat. While some athletes may be able to eat more carbohydrates and fats than others,in general, protein supplements need to have substantially more protein than other macronutrients.

Lastly, this supplement, while consciously engineered and nutritionally complete, remains affordable. This makes it a good choice for those who value fitness and strength, even if they don’t make an enormous amount of money.



This supplement has not yet won any certificates or awards. However, it’s worth noting that its manufacturer has won 35 fitness-supplement-industry awards for its products. BSN has been endorsed by bodyuilders, bikini competitors, fighters, and fitness personalities, all of whom attest that its products are an integral part of their nutrition and workout routines.



It can be difficult to base your decision to purchase and use a product on what you read without consulting others. Before you make your decision, it may be helpful to hear from other fitness enthusiasts who have tried and loved this product, adopting it as part of their own training and nutrition regimens. Here are some words from a few of them:

Don, 31, Charlottesville, VA:

When I first started working out, I didn’t really think there was any difference between types of whey protein. I guess I just thought protein was protein and went with that. Little did I know that I was in for a big surprise. I did my research and found out that proteins are not actually all the same. I learned about lots of things – essential amino acids, isolate versus concentrate, etc. And that’s when I knew I needed to upgrade my cheap drugstore protein to something better.

I kept on researching. Soon, I had found this product. I looked at the ingredients and saw that it had more than most other proteins, but I was still skeptical. What if it was all just a marketing gimmick? But I took the plunge and bought it online.

In a week or so, I was seeing and feeling results. I had better energy, I was less sore, and best of all, I could see my muscles growing. The fiber and the just-right amount of fat kept me fuller, and I lost fat, too. It’s three years later now, and I look better than ever.

Robbie, 21, Kanab, UT:

So I’ve never been what you’d call a beefcake. At all. And I didn’t mind until I got to college and joined a frat. I loved lifting with the guys, but my competitive side really came out, and I wanted to bulk up more. So I ate a bunch of lean protein – like rally a ton of it – and I wasn’t seeing any improvement, although I sure did get sick of egg whites. So I decided that I needed something else. I knew that I didn’t know enough to make the best purchase for me, so I did a ton of research and decided that Syntha-6 as the best choice for me.

I didn’t see bulk for awhile, but my strength slowly improved. It’s been six months since I started, and I feel great! I must hit a new bench PR every week or so. I haven’t told anyone my secret yet. Not sure I want to, to be honest.
