When looking for a protein powder without soy, there are several options to consider. Soy is one of the most common allergens found in protein powders, so it’s important for those with soy allergies or sensitivities to find an alternative protein source. The good news is that there are many high-quality soy-free protein powders on the market today.
Whey Protein
One of the most popular types of protein powder, whey protein is a complete protein derived from milk. It contains all 9 essential amino acids needed to support muscle growth and recovery. Whey protein is quickly digested and absorbed by the body, making it ideal for use before or after workouts. Most whey protein powders do not contain any soy ingredients, making them a good choice for those avoiding soy.
Whey protein comes in three main forms: whey protein concentrate, whey protein isolate, and whey protein hydrolysate. Concentrate contains the most fat and carbs, isolate has more protein per serving, and hydrolysate is rapidly digested. When selecting a whey protein, check the ingredients list to ensure no soy-derived ingredients like soy lecithin or soy protein. Opt for brands that state their whey is soy-free or suitable for those with soy allergies.
Benefits of Whey Protein
- High in essential amino acids
- Quickly absorbed
- Supports muscle protein synthesis
- Can aid weight management
- Mixes easily into shakes and smoothies

Pea Protein
For those avoiding dairy or soy, pea protein powder is an excellent plant-based option. Pea protein is made from yellow split peas and contains all 9 essential amino acids. It has a high protein content and is easily digested. Pea protein has a smooth, mild flavor that mixes well into shakes, smoothies and baked goods.
Compared to whey, pea protein is lower in the amino acid leucine, which plays a key role in muscle protein synthesis. However, pea protein can still help build and maintain muscle, especially when paired with resistance training. It’s also a good source of iron, making it great for those who lead active lifestyles.
Benefits of Pea Protein
- Plant-based and dairy-free
- Hypoallergenic and contains no soy
- High in branched-chain amino acids
- Has a smooth, neutral flavor
- Easy to digest
