Soy Isolate - a plant-based protein powder with a favourable amino acid spectrum and a delicious taste that stands out in dishes and drinks 

Soy Isolate is a plant-based protein powder with the content of a spectrum of amino acids that most closely resembles that of a whey protein powder. This is what makes it the go-to choice of vegans, but also other people. It boasts a high content of high-quality protein, which will help with muscle growth and maintaining the health of bones. It is sure to be appreciated by athletes who are engaged in strength training and want to achieve the best results regarding muscle growth. In connection with this, we must highlight the fact that of all the essential amino acids included, the most represented one is leucine. 

  

However, this protein powder makes for a great companion even for every enthusiast of a healthy lifestyle. This is because of several reasons. The first is its favourable ingredient profile, as it contains no gluten or lactose, which makes it suitable for people who avoid these substances. It contains no fat, has a low sugar content, and is also GLP-1 friendly. This makes Soy Isolate suitable even for the most demanding athletes, such as fitness athletes or bodybuilders in prep, who keep a close eye on literally every gram of sugar, fat, and protein. Next we have its delicious taste, due to which it once again ranks among the top tier plant-based protein powders.  

  

Last but not least, it is well-soluble, which is yet another benefit when compared to many other plant-based proteins. This makes it an optimal choice for preparing a post-workout drink. That said, you can also add it to smoothies, your favourite porridge, desserts and other dishes, which it will enrich with a fair dose of protein. This will come especially handy if you are trying to maintain a balanced diet and want to enrich each dish with enough of all macronutrients.  

 

No matter if your goal is to gain muscle mass, lose weight or eat healthy and stay in shape, in all these cases, it is important that your diet contains enough protein. Soy Isolate is therefore an effective way to meet the recommended daily protein intake, and as a result, get closer to your goals.

    Flavor: chocolate
    I am very satisfied with this soy protein! It performs its function as it should, and its taste is good. Do not expect it to taste like chocolate just because it says "chocolate," but it is certainly pleasant and easy to drink. When you open the packet, you are greeted by that cocoa aroma that reminds you of the drinks we used to consume when we were children.

    Flavor: banana
    This is a very poor protein. I bought it due to the price, but I cannot even drink it; I am not exaggerating. I prepared a 500ml glass, drank it quickly because I did not like it at all, and I vomited. I do not recommend it at all; it is better to spend a little more and purchase whey.

    Flavor: banana
    I bought it purely out of curiosity—the excellent composition and very favorable price compared to whey protein intrigued me. The taste is good (banana)—not too sweet, not cloying, and not overly artificial. The only drawback I can mention is solubility: no matter how much I shake the shaker, it still feels like I'm drinking milk with sand. I noticed in the reviews that this solubility issue is specific to the banana flavor; perhaps I will try other flavors later and update my rating to 5. Overall, I am satisfied.

    Flavor: vanilla
    Before placing the order, I read the reviews and expected the worst. Upon receiving it, I, in principle, understood the dissatisfied commenters. The taste is not very good. Quite simply not very good; I mainly mix it with water, so I know what I am talking about. It tastes better with milk. Without a shaker, it is difficult to mix thoroughly. However, I purchased it as an additional source of protein, not as a treat, and I was aware of the price and the reviews, so I have no complaints. I might order again, as it fulfills its function, and taste properties do not play a particularly important role for me. Delivery was fast, and the packaging was intact. If taste properties are very important to you, I do not recommend it. If not, I see no other drawbacks.

    Hello, GymBeam team! Thank you for the prompt delivery and for the professional manner in which the order was packaged. I purchased the soy protein isolate and am very satisfied with the product quality. It dissolves easily, has a pleasant taste (even without added flavors), and is an excellent option for those who avoid lactose or follow a plant-based diet. I would appreciate it if, in the future, more flavors were available for this product, possibly including versions with natural sweeteners. Thank you once again, and congratulations on the professionalism you demonstrate! With appreciation, Bianca

    Flavor: salted caramel
    I am confused by the negative reviews here:D I have tried almost all vegan proteins on the market, and I rate this one as very good in terms of taste and solubility. It is ground extremely finely, so it creates a bit of a mess when mixing, but that is the only drawback I can mention. Plus, the price!? I will definitely purchase it again.

    Flavor: banana, vanilla
    I purchased two units, and both are unusable. The taste is tragic; I prepared only one serving and was unable to drink it due to the terrible flavor. The product is not suitable for consumption and, additionally, dissolves poorly. It may be inexpensive, but of what use is that if it is fit for nothing?

    Salted caramel – non-edible, and now I have a kilogram of it... I cannot detect any sweetness from this flavor; it is a strangely odorous powder. Previously, I had vanilla, which was excellent.

    Extraordinary, I have been using it for some time now; I will try the banana flavor. Until now, I have only used vanilla and chocolate. Those who complain that it does not mix well clearly do not know how to measure the correct amount of liquid with the powder!

    Flavor: chocolate
    In fact, this protein has quite good amino acid profiles, with a relatively high leucine content, almost comparable to whey protein. I personally tried it out of curiosity, and I have always been annoyed by how much water it requires to avoid becoming doughy, haha. Otherwise, it is easy to swallow. Personally, I am satisfied. I am not vegan and consume various types of protein, but I would advise you to look for proteins with higher leucine content for post-workout recovery, as they naturally provide a rapid anabolic response. Additionally, you will need carbohydrates to create an insulin spike, enabling you to directly deliver nutrients to your muscles.
