BSN Syntha-6 Protein Powder Reviewed Review Facts

As far as Protein powders go, they are all basically the same. While some are plant-based and some are made with Whey you are basically looking at Protein, flavoring, and a sweetener. BSN has done something quite a bit different with their product. The SYNTHA-6 does not digest right away, it is formulated to do this slowly. Because it does this you have a boost to your essential Amino Acids throughout the entire day instead of the limited time you get from most Protein Powders. Amino Acids help reduce muscle soreness and fatigue all while ensuring your muscles continue to grow. As you can see this is an exceptionally awesome thought! BSN SYNTHA-6 does contain more calories and some other less desirable qualities but when you consider the benefit we think you will see that the pros significantly outweigh the cons. Hitting the gym hard every day can take its toll when on an extended fitness journey, ensuring your muscles feel great is imperative. On top of that, you will also find yourself losing weight easier and building muscle faster.

Most users seem to really like the taste. It mixes rather well and offers a smooth and consistent texture. Often we get a chalky or gritty feeling in our mouths after drinking our post workout shake. For some people, this is something they simply can not get past. When using BSN's Syntha-6 you can put those gagging moments behind you. With a flavorful punch your mouth with thank you for changing it up. Don't settle for chunky, chalky, non-swallowable, Protein drinks and find your daily routine is much more enjoyable. Additionally, the excellent taste helps to provide nutrients you need to keep losing weight and building muscle.


We are all used to the standard of Chocolate, Vanilla, and Strawberry when it comes to our shakes. While there are a few companies that offer options in Peanut Butter and Chocolate as well as Cookies 'n' Cream, there are very few that offer even more. BSN knows that everyone's tastes are a bit different and when it comes to post-workout drinks, the more variety the better. You can have Syntha-6 in not only all the flavors listed above but also a couple other choices that are really out of the box. This includes varieties like Cinnamon Bun, Banana, Watermelon, and Chocolate Cake Batter. When needing something a bit different these may be right up your alley.


As with most Protein Powders, when you mix Syntha-6 with water or Almond Milk, you will end up with a thick shake. The consistency is smooth. You won't find chunky, unmixed powder in the bottom. In addition, you won't have to worry about the chalky mouthfeel that is commonly associated with these types of shakes. Very few customers have negative words towards the consistency which makes us breathe a sigh of relief. If you struggle with a sensitive pallet and consistency is key, BSN's Syntha-6 could be an excellent replacement.


Muscle recovery and growth are the main reason people use products such as this. When it comes to the effectiveness of this option by BSN you really can't go wrong. You will boost your Protein intake and you will notice the difference quickly. Athletes across the globe have relied on this brand for over a decade and there is a very real reason for that. It works! Sure, you can boost your Protein in a variety of ways but the advanced science and technology behind Syntha-6 make it a step above the rest.


The ingredients list for this product is pretty long and for some will make it an absolute no go. If you want all natural options this is not the one for you. Their ingredient list starts with a mix of Proteins which include Whey Protein Concentrates and Isolates, Egg Albumen, Glutamine Peptides, Milk Proteins, Calcium Caseinate, and Micellar Casein. These are relatively common but then they add Sunflower Creamer, flavoring that is natural and artificial, Polydextrose, Cocoa, MCT Powder, Salt, Potassium, Sucralose, Bromelain, and quite honestly a variety of other things. As you can see, this is certainly not a natural or vegan-friendly choice.


The whole purpose of taking on a daily shake is to pump up your Protein. Our bodies need roughly one gram of protein for every pound we weigh. Most people do not get this in their diet so adding in an extra boost can be very helpful when working hard to increase your muscle mass. BSN's Syntha-6 offers twenty-two grams of Protein per serving. This is pretty average in the world of Protein supplements. There are options that offer more and many that offer less. This is a great amount to start with and can help you easily meet your Protein goals for the day.


Sucralose is the artificial sweetener used in this product. A large variety of people will tell you to stay away from artificial sweeteners and stick with products that are all-natural. Honestly, it is up to you and what you find works best for you. Sucralose is commonly used in these supplements. It can be overpoweringly sweet, however, it seems that BSN has gotten the formula pretty well balanced. There are not a huge amount of reports for over sweetness.


Stayin in control of your carbs is exceptionally important if trying to lose weight and maintain a healthy lifestyle. Adding a bunch of carbs into your diet through your supplements is not something any of us need or want. The carb content in this is about fifteen grams per serving. This is quite high compared to others in the market. If you don't struggle with an overabundance of carbs in your life this may be fine. Finding carbs are a bit of a downfall? You may want to veer away from this because you may find you are going over your daily allowance in the carb category.

Amino Acids

Every serving is packed with ten grams of essential Amino Acids. When it comes to muscle growth and recovery, Amino Acids are what make it happen. Our bodies naturally produce a certain amount of this much-needed recovery tool. However, we don't make everything we need and what we eat helps to ensure we maintain healthy levels. This not only aids in reducing soreness but also in overall muscle growth. Ten grams of Amino Acids is pretty good and quite a bit more than other options on today's market.


Fillers are commonly used in dietary supplements. Some find this unfortunate and head toward more natural products for others it is really no big deal. Syntha-6 does use fillers but the overall benefit of this product outweighs the use of fillers. Many of the customers that buy this product swear by it because of its great flavor and proven track record of helping you build muscle. Fillers are there to take up space but when everything around it is working overtime to help you, it is easy to accept and overlook.


One scoop equals one serving. This is pretty standard in this category. Of course, you can adjust how many servings you use in a day based off of your daily need. There are roughly twenty-eight servings per container. This will mean you need to purchase a new container monthly or order more than one at a time. Overall, it is a good investment for a months worth of Protein boosting powder.

Side Effects

This option carries a few more side effects than others. This may be due to the fact that their ingredient list is so long. As with most Whey products, there is always a chance for stomach upset, nausea, and vomiting. Especially if you have a lactose intolerance. Additionally, people have reported cramping, flushing, and an in general bad feeling. Lastly, there have been reports of both diarrhea and constipation after extended use. If you have adverse side effects to any product you should discontinue use immediately as you may be having an allergic reaction and that can be life-threatening.


The obvious advantage of adding this into your daily routine is the fact that you will increase Amino Acids through a punch of protein. The not so obvious but equally important advantage to this product is the amazing flavors and consistency. Thinking outside of the box you can have a great variety in your daily shakes which in turn keeps things interesting and different. On top of that, you won't have to worry about a bad feeling left in your mouth or trying to gag down a gritty, chunky, drink.


There are a few disadvantages when deciding this is the product you want to purchase. First, you will get enough for about twenty-eight days of use, if only using it once a day. That means needing to make a purchase for Protein more than once a month or spending more at once to make sure you have enough. Next, there is the long list of ingredients. Keeping things natural and simple can really benefit us over the course of life and all the extras are not only unnecessary but can actually inhibit us from being our healthiest selves. Lastly, the carb rate in it is a bit high. As stated before, keeping carbs down is a good thing so the need to accommodate the carbs in this shake can be difficult.


A lot of research and time has gone into perfecting BSN's line of products. When it comes to quality, they are at the top of their class. Flavor, texture. mixing ease, and, effectiveness is all of the highest quality. The only thing that reduces the quality of this product is the fillers used as they are not needed for a great product. If you decide to give this a try and have tried a variety of Protein Powders, you will find overall this one is better in just about every way.


Syntha-6 is a step above many other options because of the quick effect. In addition, the cost is a bit above the others. Most budgets that are already buying these type of supplements will absorb the cost quite easily. If this is a new venture for you then you may need to do a bit of adjusting. The benefits of adding extra Protein into your life certainly outweighs the price. This product is simple to use and offers a great taste for a reasonable price. The value exceeds the cost and what you will end up with is a reliable product that helps you exceed your fitness and gym goals.
