Best Soy Protein Powders of 2025

"I’m thrilled to have discovered this unflavored, unsweetened pure plant-based protein powder. As a vegetarian and occasional vegan, it’s tough to get enough protein without consuming too many carbs. This simple soy protein powder brilliantly balances out overly sweetened vegan powders, making them much more palatable. I even enjoyed it on its own mixed with dark chocolate almond milk!"

"I’ve tried numerous protein powders, and I must say, there will likely never be a completely flavorless or tasty protein powder. However, this one is surprisingly good. While it adds a bit of chalky texture, it’s quite tolerable. I love using it in fruit smoothies, especially with peanut butter and banana!"

"This soy protein powder exceeded my expectations! It has no artificial sweetness that I found with other brands, and it blends easily with pure milk in my shake-container. It tastes just like unsweetened soy milk, which is exactly what I wanted."

"I eat this every day. I mix it with other foods, like flavored protein powders or oatmeal. It's tasteless and adds lots of protein without anything else! No artificial flavors, no dyes, no carbs, no fat! Just protein. And it's cruelty-free. BUY IT!"

"As an individual with allergies to additives, thickeners, and preservatives, I appreciate this high-quality product. There's no extra ingredient. Please, don't ever change this!"

"I buy this in bulk to add to my morning drink, usually hot chai or cappuccino. The last batch mixed well, and I felt good adding protein and amino acids to my diet. However, this new batch is less compact and does NOT want to mix. It floats on top, creating a thick, lumpy foam. This change is disappointing."

“I love mixing my own chai or chocolate protein mixes, and this product serves as the perfect base. It adds protein to my drinks while being dairy-free. It tastes great and has a smooth texture. The size is just right for making two batches of my favorite flavored protein drink. I will definitely be ordering this again! Thank you for such a good value and great product!”

“I regret purchasing this product. It does not mention organic anywhere, and I am aware that 90% of soy in the US is treated with chemicals. I feel like it was a waste of money. The bag does say in small letters that it is non-GMO, but I don’t trust it since nothing on the bag confirms that. It's important to read carefully what's on the packaging!”

“I'm a huge fan of protein shakes, and Earthborn Elements Soy Protein has been a game-changer for me! Each scoop packs 25g of protein, which is perfect for my workouts. Plus, the giant bucket lasts forever, making it a super cost-effective choice. It blends seamlessly into my smoothies without that chalky aftertaste, and I trust it because it's clean and pure with no weird additives. This has truly become a staple in my post-workout routine!”

“I decided to try this unflavored soy protein after my usual brand was out of stock. While it does have a chalky texture, it blends well with flavored milk. The value is outstanding; I've purchased it multiple times, and it really helps me meet my daily protein needs. Just a note, my last tub had a weird piece of packing paper mixed in, so I’m giving it 4 stars, but overall, it’s a fantastic bargain.”

“Finding a budget-friendly vegan protein was a challenge until I stumbled upon this product. I appreciate the large bucket size, which is helpful, though the lid can be a bit tricky to remove. The powder itself is a little gritty, but with a banana or two in my smoothie, I hardly notice it. For the price, I'm absolutely going to buy it again!”

"I found myself adding this protein powder to just about everything. It worked really well in my dishes, and the smaller serving size is intentional due to the soy flavor. However, when mixed as instructed, the flavor is hardly noticeable. It dissolved easily in water and was quite drinkable, making it a great option to boost protein in meals."

"I decided to try this soy protein isolate powder as a change from whey. It has zero carbs, which is perfect for my low-carb diet. While the flavor alone isn't the best, it mixes well with fruits and other ingredients, creating a surprisingly tasty shake. I appreciate that it's a complete protein, making it a solid option for my needs."

"This protein powder blends smoothly into my post-workout shakes without altering the flavor. It's vegan and gluten-free, which is a bonus for my dietary requirements. I also love that it doesn't have any grittiness, making it a great addition to my smoothies."

"I've been using soy protein isolate for years, and I can confirm this is not the same as what I'm used to! It clumped badly in my smoothie and had a strange taste that wasn't typical for soy. I'm really worried about the product's origin and, unfortunately, I can't return it!"

"I was delighted to find this soy protein after Amazon stopped carrying my previous brand. The Pure Original comes in a large 4-pound bag and mixes well with water. I usually add a scoop of flavored protein to enhance the taste, and I'm committed to buying this regularly from now on!"

"This soy protein is simple and effective, with no added chemicals. It works perfectly for me, but I recommend mixing it cold since heating can make it gritty."

"I've relied on this soy protein isolate for years. It has no flavor, just a white powder that mixes well. Occasionally, I see small bubbles of dry powder, but they crush easily against the glass. The packaging is great too; I repurpose the empty jugs!"

"As someone new to protein powders, I was pleased to find this one without sugar or flavoring. I consulted with my brother-in-law, a licensed dietitian, and he thinks it's an excellent choice. My first smoothie didn't alter the flavor much, and while there’s a bit of grit, it's not off-putting. Perfect for my protein goals!"

"I must say, the taste isn't great. I tried adding flavor to it, but it still didn't work. I was hoping for something similar to Revival Soy Protein, but this missed the mark for me. I don't think I'll buy it again."

“I’ve been using this shake for 20 years to control my appetite, and I love adding frozen or fresh fruit for an awesome taste.”

“I’m not a breakfast person, so I make a shake in the morning, and I absolutely adore this brand! The price and flavor are fantastic, but I’ve struggled with availability recently.”

“The horchata flavor is more like the milk after cereal, but it's still really tasty! I love how it doesn't have the typical protein powder taste.”

"I love how this mixes easily with my unsweetened almond milk, providing a quick protein boost!"

"After searching for a new protein powder since EAS was discontinued, I found this one. The vanilla flavor is similar but less sweet, which is perfect for me!"

"This protein powder has a rich chocolate flavor that I enjoyed from just a dab. Although the price is a bit high, it’s smooth and works great in my smoothies and health shakes!"

“I absolutely love the great vanilla flavor of this protein powder. It mixes really well with cold almond milk and doesn't clump up. While I find it a bit high in sodium, it’s not a major issue for me. I’ve tried both the vanilla and the unflavored versions, and while I enjoy both, the unflavored one is more versatile for mixing into other foods.”

“For my daily smoothies at work, this protein powder has become a staple. It blends seamlessly with my usual kale and fruit mix. The vanilla flavor complements the fruits nicely, and I appreciate the absence of any grittiness. Overall, I'm really pleased with this addition to my smoothies.”

“As someone who is new to protein powders, I find this one quite decent. I mix a scoop into my smoothies, and it doesn’t leave a chalky taste. Although I'm not a fan of stevia, I barely notice it. The vanilla aftertaste is pleasant, and for the price, I think it’s a good simple protein powder.”
