8 Best Soy-Free Protein Powders (2024) | #1 Cleanest Product!

It’s no secret that soy protein powders are controversial and are not really the best plant-based option for anyone.

For one thing, soy contains phytates that block nutrient absorption. This would generally render your protein powder useless and means that you won’t really be getting any of its benefits.

Despite this, it can be difficult to navigate the many protein powders in the market to make sure they’re free from soy. After all, they’re a fairly popular protein source and are used as instantizers.

In this review, we’ll take a look at 8 of the best soy-free protein powders on the market to help you soak up all the nutrients and minerals you need.

8 Best Soy Free Protein Powder (List for 2024)

Despite the popularity of soy protein, which we often see used in tofu and other protein sources like soy sauce, It’s not really the ideal protein source you thought it was. Sure, it’s a viable option for anyone who wants to stick to a plant-based diet. But there are risks associated with taking soy supplements. Not to mention, it really isn’t the most effective source of protein.

What are the Benefits of Taking Soy-Free Protein Powders?

Although soy protein is arguably not the most effective protein choice, not to mention the controversy that surrounds it in the health community, it is a complete protein. This means you’re getting a complete amino acids profile when you take soy protein. That’s all of your daily amino acids requirements that your body can’t produce on its own, fulfilled.

Having said that, soy remains controversial if only for the fact that it stops your body from absorbing nutrients and minerals that are otherwise essential to your health. That said, there are many benefits to steering clear of supplements that contain soy.

Benefits Soy Free Protein

Here are my key takeaways:

  • It can impact your hormone balance – phytoestrogens are found in soy. Specific phytoestrogens are known to bind with estrogen receptors in humans, which leads to hormonal imbalance. This means your estrogen levels will rise and could lead to problems that affect both men and women.
  • Soy can block nutrient absorption – no matter how many nutrients and minerals are found in your protein powder, the presence of soy—and consequentially, phytates, make it difficult for your body to absorb them. This means your body will either throw away those nutrients or take incredibly long to absorb them.
  • It’s a well-established allergen – you may or may not be allergic to soy. Despite that, it doesn’t discount the fact that soy can cause a myriad of problems that are physically prevalent. For example, acne, asthma, and a host of other skin allergies like eczema.
  • It is usually highly processed – let’s get one thing straight: YOU DO NOT NEED YOUR PROTEIN TO BE INSTANTIZED. Got it? Well. It might make your protein powder easier to mix, but it’s completely necessary. There are plenty of options that are easy to mix without using soy to instantize it. Furthermore, soy is usually highly processed. Which, I don’t have to tell you twice, isn’t a good thing in any case.

That said, there are certainly ways soy is used that aren’t completely bad for you. However, it wouldn’t really be worth your time to research it for hours when there are other, more effective options in the stores. Take Transparent Labs, for example, they produce a high-quality protein powder that is soy-free and contains all of your essential amino acids.

Frequently Asked Questions

Is Pea Protein Soy Free?

There are some pea protein powders that are soy-free. However, that doesn’t mean that all of them are. Take your time to review the ingredient list and make sure that soy is not included. That said, it is a viable vegan option for anyone who is looking to stick to a plant-based diet.

Does Whey Protein Powder Contain Soy?

Some whey powders use soy to instantize their formula. This makes it easier to mix the powder. However, not all whey powders contain soy. That said, there are definitely whey powders that do not contain soy.

Is Soy Protein Powder Bad for You?

This is a widely debated topic. But if you’re asking me and other professional health buffs, you’ll hear the same answer: soy is not worth your time. While it may not immediately be bad for you, it can lead to a host of health issues in the long run.

Does Soy Cause Weight gain

Does Soy Cause Weight Gain?

Like any other protein powder (Like Orgain Organic with 7 grams of fiber ) out there, it can help with healthy weight gain. The only issue is that you’re likely not absorbing any other nutrient into your body whenever you take soy protein or powders that contain soy.

What is a Good Substitute for Soy Protein Powder?

A suitable substitute for soy protein powder depends on individual dietary preferences, allergies, and nutritional goals. Several plant-based alternatives offer comparable protein content and nutritional benefits.

Pea protein powder stands out as an excellent substitute for soy protein. Derived from yellow peas, pea protein is rich in essential amino acids, particularly lysine, which is often limited in other plant-based proteins. It is easily digestible and suitable for individuals with soy allergies.

Brown rice protein powder is another viable option. Extracted from whole grain brown rice, this protein source is hypoallergenic and complements a balanced amino acid profile when combined with other plant-based proteins. It is easily digestible and suitable for those with soy or gluten sensitivities.

Hemp protein, derived from hemp seeds, provides a well-rounded nutritional profile with omega-3 fatty acids, fiber, and essential amino acids. It may have a slightly nutty flavor and is suitable for individuals seeking a diverse nutrient profile in addition to protein.

Quinoa protein, extracted from quinoa seeds, is a complete protein containing all essential amino acids. It is gluten-free and suitable for those with soy or gluten sensitivities.

Algae protein, such as spirulina or chlorella, is a unique plant-based option. These algae contain a notable amount of protein and provide additional health benefits, including essential vitamins and minerals.

Ultimately, the choice of a soy protein powder substitute depends on individual preferences and dietary restrictions. Each alternative offers distinctive nutritional advantages, ensuring a diverse range of plant-based protein options to suit various needs and preferences.

User Reviews, What Customers are Saying?

Going soy-free is a decision that you need to make right now. If you value your health and your money, soy products are not worth the investment. Hear a hundred other customers and me out:

  • Soy is NOT essential to your diet. Contrary to its popularity, soy is not an essential protein. In fact, even if you are a vegan, there are many other alternatives that are much more nutritious. For example, mushrooms and cauliflower.
  • There are many plant-based alternatives that are better than soy. If you’re strictly vegan, I suggest a blend of pea and brown rice protein. You’ll also find success with hemp protein, which is more easily digestible compared to soy.
  • Soy can cause stomach distress, liver failure, and a myriad of other health complications. Numerous studies show what constant soy protein intake does to your body. Aside from acne, asthma, and skin conditions, you’re more likely to have digestive issues with soy in your diet.
  • Choose something unflavored. If you want to get something that is as pure as it gets with all of the benefits, make sure you go for an unflavored powder. Yes, the chocolate milkshake flavor is tempting, but it’s not really that versatile.
  • Start with sample size, if possible. If you’re just testing out the waters—so to speak, it’s important to try and buy the smallest pack available. This will help you minimize your costs when you’re not yet sure which product to buy.
  • Choose something safe, natural, organic, and hormone-free. You may not know it, but some things you should look for is a Non-GMO assurance, or if you’re lactose intolerant, look for something gluten-free dairy-free, and lactose-free.

Consumer Reports

Summary: Overall, you should really just stay away from any protein powder that contains soy. It’s honestly not worth your attention. That said, there are plenty of options in the stores. Make sure you’re buying something that is right for you and wil cater to your specific goals and dietary restrictions.

Where to Buy

There are many retailers that carry soy-free protein powders. I’d start with GNC and Amazon since they carry many choices and some of the most popular brands in the stores. Moreover, you could also try shopping at Walmart.

Does Whey Protein Have Soy?

Ingredients are the key to a great product. Soy is a component of many protein products. Soy protein, however, may be highly problematic for some individuals, and it can be an easy choice for those trying to avoid or manage soy sensitivity or allergy. Per the FDA’s definition of soy protein, if Soy protein isolates contain soybeans and at least 2% of soy protein, then they are not considered to be a protein or protein-based products, and they are not allowed to carry the “Whey Isolate” or “Whey Concentrate” label.

It is important to note that soy is found in many soy products, including meat alternatives, tofu, textured vegetable protein, baked beans, and a wide variety of commercial soyfood products, such as veggie burgers, veggie dogs, and low-fat bean dip. If you have a sensitivity or allergy to soy, then Soy protein isolate is unlikely to be a good option for you. If you want to avoid soy entirely, however, there are a number of alternatives that can help you meet your nutritional goals. Gluten-free. If you are sensitive to gluten, it is likely best to choose a product that does not contain any gluten. Several brands of protein powders are available that are manufactured with only protein ingredients, and none contain gluten.

Does Rice Protein Have Soy?

Contrary to the results of our previous article, it seems that there is no threat of soy protein blend from vegetarian sources. A 2006 study in China indicated that soy protein and soy isoflavones may be interchangeable. According to the article, the researchers were surprised to find that beans, soy, and tofu have the same amount of isoflavones as soy milk. This was especially surprising because most foods, such as tofu, are used for making soy milk. However, beans and beans are different enough to provide the essential nutrients necessary for healthy absorption.

Does Lentils Contain Protein? Lentils are primarily consumed for their fiber and are considered a type of whole grain. They are classified as “green” food, since they contain higher levels of phytonutrients, such as antioxidants, that may help prevent chronic diseases. This study found that when lentils are roasted, a short cooking time may result in a high amount of cysteine. Cysteine is an amino acid that may be dangerous for those who have Celiac disease if it is not properly filtered from the food during processing. Due to this small amount of cysteine, though, the researchers were not concerned with the results.

Do All Protein Powders Contain Soy?

Just because a protein powder says it doesn’t contain soy doesn’t necessarily mean it doesn’t contain soy. In fact, one of the most popular powders, Soylent, contains small amounts of soy, and other companies make their powders without soy to align with the current scientific consensus that soy consumption doesn’t negatively impact health. And in some cases, soy is the protein the manufacturer deems most easily digestible for its users. Bottom line: If you’re allergic to soy, steer clear of any powders labeled as soy-free or no soy. As noted by the Weston A. Price Foundation, protein powder producers have the right to exclude specific powders from their products, but “consumers should be able to find out which ones, and whether a specific product contains a potentially allergenic protein.

Is Soy Bad in Protein Powder?

Protein supplements are made up of three main ingredients, whether it’s protein, creatine, or anything else. But who wants to know how all those different sources of protein come together to make their protein powder? It seems like a lot of people really care, so I’ll tell you a little about the proteins themselves. Here’s the breakdown of protein: Ethanol, Casein, and Gluten. This first part of the protein breakdown includes glucose, lactose, and casein. Gluten is short for glutenin. Glucose is the star product in most supplements, and it’s usually a combination of glucose and fructose. Lactose is the main source of fructose, which makes it digestible. But I’ve heard stories of people taking a sugar-free protein.

Does Garden of Life Protein Powder Contain Soy?

As you can see, the ingredient list is incredibly short, which is where the confusion occurs. A company called Garden of Life provides the soy protein for the product. Yes, there’s soy protein. There’s also soy flour and sweetener. The biggest ingredient in Garden of Life protein powder is vegetable and egg fiber. Vegetable and egg fiber contains soy protein, but it also contains guar gum, as well as various other ingredients that the label does not describe.

This is the only ingredient that is listed in excess, not on the label. The rest of the ingredients can be found in the ingredients database. Here’s what it says about guar gum. Guar gum is one of the few ingredients in this product that doesn’t require any explanation, as it is widely used in all sorts of non-dairy products. We have listed a healthy dose of it.

Final Words. What is the Best Soy Free Protein Powder?

Overall, numerous studies support the fact that soy can be harmful to your health. If you’re a health buff like me, it’s seriously not worth the risk. Especially not with so many alternatives in the market.

Despite its popularity, you need not worry. No matter your dietary choices, there is something that is suitable for you. Protein powders are highly popular and helpful for anyone who needs to incorporate more protein into their diet. Below are some of our top picks:

Ultimately, it all boils down to your preferences. No matter which product you choose, we’re confident we’re pointing you in the right direction with the choices listed above.
