Best Soy Protein Powder

Soy Protein Powder

When looking at the world of fitness, it is all about sustainability. Not only do you have to be consistent with your workout routines to ensure it remains sustainable, but you also need to buy sustainable products. The best soy protein powder is one of the best options for sustainability. But you should also ask; “What is soy protein powder?” before buying just any product

Most soy protein powders are equal in terms of the quality of the product. However, you will need something from a reputable brand to ensure that the label information is what you receive inside the powder. Soy protein is derived from the humble soybean and it is stacked full of nutrients and properties to help your workout routine.

In the following article, we take a deeper look at soy protein powder and help you discern which of these powders are the best. The buyer’s guide will make it easier for you to see how we went about selecting these products. Additionally, we have included some of the top products to reduce the need for you to search for them.

What Do You Need To Look For When Buying Soy Protein Powder?

Before buying any protein powder, you have to consider a couple of the features. Once you understand the features of the product, it is much easier to find the product that meets all your needs. We have done some research to help you determine which features are the most important. The following guide should help you in finding the best soy protein powders:

Protein Serving

One of the first things to consider is the amount of protein per serving. You want to have an average of between 20 and 30-grams of protein per serving and the scoop size should not exceed 40-grams. Yes, there are additional elements one can consider healthy, but you want a decent ratio when comparing the serving to the protein powder.

Soy Protein Type

Once soybeans go through the centrifugation process, soybean concentrate is generally the first form that is extracted. It enters an ethanol extraction that removes some of the additives and leaves you with a concentrated form of the soybean. However, will have around 4% of the estrogen from the original soybean.

Alternatively, one can look at soybean isolate, which has gone further centrifugation and removes even more of the additives. While it has a high concentration of pure protein, it also retains 35-45% of the estrogen from the soybean. This means that men who are cutting out estrogen might not find it the best option.

Calorie Content

One of the most important parts of selecting any protein powder is calorie content. Most people looking to buy a new form of protein will want to keep the calorie content to a minimum The most common protein powders will have around 150-calories per serving, which should be fine for those on a strict diet.

You want to look at the calorie content to find out if any carbohydrates and fats are present. Anyone looking to lose weight will understand that these are two of the main macronutrients that need to be controlled. Many of the top soybean protein powders will often have a “low-calorie” indication to ensure they are ideal for dieting.


Fortunately, soy protein is not as expensive as whey protein, but there is always a price to protein ratio to keep in mind. While this will vary from brand to brand, you must consider the price of the protein powder. We don’t recommend overspending on something that you will not use to reap all the benefits from.
