It remains to be seen just how much influence eating whole soy products may have on human hormones - a further exploration into this area is needed!
Which Protein Does Not Have Soy?
There are plenty of non-soy protein powders out there. Plant-based proteins like hemp seeds, chia seeds, pea protein, brown rice protein, flax seeds, quinoa, amaranth, sunflower seeds, pumpkin seeds, etc., are the most common sources of plant-based protein powders with no soy. And if you’re wondering, “Can plant-based protein powders without soy be a complete source of protein?“ Yes, they can, especially with various blends of grains and legumes. Each of these proteins provides its own unique benefits when it comes to providing nutrition and muscle-building support. Here are some of them:
- Pea protein: This plant-based protein is made from yellow peas and is a good option for vegetarians and vegans. Pea protein is also a great source of iron and can support muscle growth, weight management, and heart health.
- Rice protein: This plant-based protein is made from brown rice and provides the body with nutrients called amino acids that support normal blood flow. Another good option for those on a plant-based diet.
- Brown Rice protein – Brown rice is hypoallergenic and easily digestible, offering a wealth of nourishment beyond just protein. When combined with pea protein, it forms an ideal balance that provides all essential amino acids without the unwanted chalky or gritty texture found in many other proteins. Perfect for those looking to maximize their intake!
- Hemp protein: This plant-based protein is rich in omega-3 and omega-6 fatty acids and made from hemp seeds. It's a complete protein and is easy to digest, and it is known to help to maintain lean body mass and maintain brain function.

What to Know When Buying Soy-Free Protein Powder
When you’re purchasing your protein powder without soy, it’s best to keep some things in mind. Here's a little comprehensive list:
- Focus on the source of protein - When selecting a protein supplement, the most important thing you should check is the source of protein. If the entire supplement is based on soy protein, you can surely skip it, especially if you have had any ailments in the recent past. Plant-based proteins extracted from rice and pea can be great options, especially if you’re following a vegan diet.
- Check the label for allergens / Check ingredients separately - This will help you ascertain that the supplement has no ingredients you are allergic to. You will want to stay clear of products that mention soy or soy lecithin in their ingredients list. Some labels mention that the powder contains some traces of soy. Also, stay away from these, especially if you are allergic to soy!
- Focus on the protein content per serving - A single serving of some protein powders can include more than 1 scoop. Hence, focus on serving instead of scoops for the protein and caloric content.
- Gluten and Dairy Content - Just avoiding a single allergen like soy will not serve the purpose. Even for a soy-free protein powder, you should ensure that the ingredient list does not mention any other possible irritants like gluten, dairy products, or any other GMP ingredients.
