Which Fitness Goals Can Be Obtained with Soy Protein Isolate?

Soy Protein Isolate can be used for a variety of fitness goals; this includes but is not limited to weight loss, sports performance, muscle building and endurance. Due to its versatility where fitness goals are concerned, Soy Protein Isolate is the advised vegetable protein powder to replace dairy-based supplements.

How Is Soy Protein Isolate Made?

In order to create Soy Protein Isolate, manufacturers need to obtain and isolate the necessary protein from the soybean. During the manufacturing process, the soybean has to go through two distinct processes, more specifically dehulling and defatting.

The unique processes used to make this vegetable protein powder do provide some benefits to consumers looking to use this vegetable protein powder in their training regimen. Thanks to the manufacturing processes, it is possible to separate three different types of protein. These proteins are then used for products such as soy flour, soy protein concentrate and soy protein isolate.

What Is the Difference Between Soy Protein Isolate and Concentrate?

Soy Protein Isolate is considered the most refined form of the vegetable protein powder, because it contains a minimum of 90% soy protein. This vegetable protein powder tends to contain less carbohydrates and fat as well, since these unwanted substances are removed during the various processes Soy Protein Isolate has to go through.

Even though carbohydrates and fats are needed in a balanced and healthy diet, they are less useful for athletes on a calorie-controlled diet. Because of the removal of most carbohydrates and fat from vegetable protein powder such as Soy Protein Isolate, athletes can add this supplement to their normal diet without any problem.

Compared to Soy Protein Isolate, Concentrate contains less protein; this is on par with other popular protein powders on the market, where a protein concentrate tends to have less protein than the isolate variant. That being said, Soy Protein Concentrate still contains 70% of protein, so it is still an excellent choice for athletes trying to gain more muscle.

To create Soy Protein Concentrate, manufacturers have to remove carbohydrates for soybeans that have been defatted. Because of this process, Soy Protein Concentrate has less protein, but more fibre than most other soy protein varieties. For that reason, Soy Protein Concentrate can also be a great choice for athletes struggling to digest certain supplements.

What Is the Amino Acid Profile of Soy Protein Isolate?

Soy Protein Isolate is considered a complete protein; this means that the protein supplements contain all nine essential amino acids. With all nine essential amino acids, you do not only promote good general health, but also increase your chances of building more muscle mass.

The nine essential amino acids that make up a complete protein are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. In addition to these essential amino acids, athletes will also find branched chain amino acids in certain supplements, which can also be useful for muscle building and muscle repair.

How do I Use Soy Protein Isolate?

Soy Protein Isolate is a supplement that can be used two to three times a day, depending on the fitness goals you have set for yourself. Ideally, this supplement is taken between meals. Of course, athletes can also use Soy Protein Isolate right before or after a training session.

To create your delicious Soy Protein Isolate shake, you will need 30 grams of the protein powder and 200-250 millilitres of water or skimmed milk. Simply add the powder to your preferred amount of liquid and shake for at least 30 seconds. Then, enjoy your shake, but be sure to consume it within 30 minutes of making it!

Nutrients Direct also takes into account the personal taste preferences of athletes, which is why we provide this delicious shake in three flavours: natural, vanilla and chocolate. When you intend to use this shake in combination with a calorie-controlled diet, please note that the total number of calories may depend on the flavour. Therefore, always check the calorie count of your flavour before purchasing.

Can I Use Soy Protein Isolate as a Meal Replacement?

Soy Protein Isolate is not a meal replacement, but an additional to an already balanced and nutritional diet. However, if you are looking for a meal replacement due to a lack of time and a busy lifestyle, Nutrients Direct has some options for you.

One of the meal replacements in the Nutrients Direct range is ND Naturals Complete, an excellent choice for athletes who do not want any artificial sweeteners in their meal replacement. Instead of artificial sweeteners, Nutrients Direct uses a natural sweetener called stevia, which means you can have a meal replacement without having to worry about the added chemicals inside.

ND Naturals Complete offers athletes more than the right nutrients to keep the body healthy, since our Naturals Complete supplement contains high levels of protein that will reduce any cravings or hunger pains you might experience as a result of your diet. ND Naturals Complete also contains many amino acids, which will assist with the growth of lean muscle.


Soy Protein Isolate is quite versatile and suitable for a variety of athletes. Whether you are vegetarian, vegan, or simply looking for a vegetable-based protein that is easier to digest than dairy-based protein, Soy Protein Isolate will be an excellent option for you.

Soy protein isolate is another popular vegetable-based protein supplement available on Nutrients Direct, so if you are no fan of pea protein isolate and rice protein isolate, the soy protein supplement may be the solution for you. Soy protein isolate also provides a large range of benefits, which are comparable to the numerous benefits provided by whey protein and casein protein supplements. Soy protein isolate is commonly used for weight loss, but also sports performance, muscle building, endurance, women’s fitness and the athlete’s overall health. The supplement is also available in a variety of flavours; this to make sure that every athlete finds a soy protein isolate they love.

Athletes can use soy protein isolate up to three times daily. Athletes can use the supplement between their meals, before a workout or even after a workout. Of course, the time athletes will take their soy protein isolate will depend on the advantages they wish to benefit from. For example; if the athlete in question is focussed on muscle building, they will be more inclined to take their soy protein isolate after their workout. However, if the athlete is focussed on enhancing their performance, they could take it before their training as well.
