2. Naturade Total Soy Weight Loss Shake
If flavor is your main criteria in choosing a soy protein powder, this one from Naturade should come first. This is possibly one of the best tasting protein powders I’ve ever tried.
One of my female clients swears by this and reports how it’s able to effectively curb her appetite.
It’s not the best when it comes to protein content, as it only serves 13 grams of soy protein for every 2 scoops.
Personally, I’m okay with the sweetness and the variety of flavors. But if you’re looking for something less sugary, then this might not be your best choice.
3. Bob's Red Mill
Bob's Red Mill Soy Protein Powder prides itself on being a natural alternative to traditional protein supplements.
This product is a nourishing source of protein that is dairy-free, gluten free, unflavored, and unsweetened. It is one of the cleanest soy-based protein isolate powders on the market today.
This means that you don't have to worry about consuming any artificial chemicals in your protein shake when you choose to add a scoop of Bob's Red Mill Protein Powder.
Also, it only contains 80 calories per serving. While it may not be enough as a meal replacement, it may still help you with your weight loss goals.
As an added benefit, every product from the company is certified Kosher and is millstone ground at slow speeds, ensuring that the nutrients and flavor of the grains are preserved, which means that you can know you are buying a high-quality product.
4. Six Star Pro Nutrition
Six Star Pro Nutrition Elite Series not only has 100% soy protein, but it also has all nine essential amino acids, which means that it has what you need to help stimulate muscle building and muscle recovery after those high-intensity workouts.
And yes, this protein powder is made for high-intensity workouts.
How can we tell?
Because Six Star Pro Nutrition Elite Series Soy Protein Powder contains added B6 and B12 vitamins.
As endurance athletes, these ingredients helped keep our blood sugar within the optimal range and protected us against anemia during our oftentimes insane workout sessions -- something that other protein powders are not able to do.
5. Advanced SoyPro
Created by Universal Nutrition, Advanced Soy Protein is an optimum protein supplement that can be used whether or not you are a serious athlete.
This protein powder has the essential amino acids that your body needs to convert protein into muscle.
The 100% water-washed process also ensures that you get the optimal benefits without any harmful additives.
By not exposing the product to the ethanol wash that is common with other soy protein supplements, your body gets the high levels of isoflavones that are found in soybeans naturally and consequently, the maximum benefits from soy.
What Is Soy Protein?
Like other common forms of supplemental protein, soy protein has many positives and possible negatives for your health. The Soyfoods Association of America has defined soy protein isolates as the following:
Soy protein isolate can be found in a wide variety of health foods, ranging from protein bars, meal replacement shakes, bottled fruit drinks, meat substitutes and baked goods.
Soy protein isolate is a dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein and nearly carbohydrate and fat-free.
You should know that soy is an ingredient in your food if you see one of the following terms on the nutrition label: mono-diglyceride, soya, soja, yuba, TSF (textured soy flour), TSP (textured soy protein), TVP (textured vegetable protein), or MSG (monosodium glutamate).
Though not all textured vegetable protein comes from soy, a good amount of it does, while lecithin can be made from soy, eggs, or corn. To know for sure what is in your food, you can contact the manufacturer for a more detailed ingredients list. 
The 2 Different Types
There are two main ways that soy protein is manufactured and sold:
1. Soy protein concentrate - formed when the fat content is taken out of soybeans, leaving a white flaky substance in its place.
After these flakes are given an ethanol extract to neutralize its pH levels, the substance is solid enough to be sold or used within prepared foods.
Because of the ethanol extraction, soy protein concentrate has a low level of isoflavones (plant-derived estrogen) usually around 4% of the initial amount within the bean. 
This makes soy protein concentrate a smart protein supplement for men that are worried about the side effects of consuming estrogen enhancers.
2. Soy Protein Isolate - After the formation of white flakes in soy, the concentrate is processed one more step through centrifugation that extracts the highest percentage of protein by weight.
The isoflavone levels remain higher (35-45%) than in soy protein concentrate because the step of ethanol extraction is skipped. Men that are concerned about estrogen should avoid taking large amounts of soy protein isolate.
Is Soy Protein Bad for You?
In recent years, these products have been getting a bad reputation. Many people believe that the majority of health claims for soy are actually false and the result of clever marketing schemes from food companies.
Some of their worst claims to the contrary are as follows:
You might be ready to swear off soy-based products for good after reading some of the purported negative health effects, but the truth is, the vast majority of soy products are not dangerous and are actually nutritionally beneficial instead.
Overall, soybeans have an impressive nutritional record. Each bean contains 30% carbohydrates (half of which are from fiber), 18% oil, 14% moisture, and a whopping 38% protein.
Research into the benefits of soy protein have shown that they can help lower your LDL cholesterol levels by as much as 5%. [
While that might not seem like much, small differences in your cholesterol level can have a big impact on your overall health.
Simply choosing to consume organic soy-based products reduces your risk of being exposed to estrogen-damaging herbicides.
Likewise, here is a simple way to get rid of the negative hormone effects of soy and instead make it a safe and healthy food source: fermenting it.
The process of fermenting soy destroys the dangerous compounds it contains and makes it both safe and beneficial to eat.
Historically, Asian populations have eaten large amounts of fermented soy while being some of the healthiest and longest-living people in the world.
Other evidence has shown that eating fermented soy can prevent osteoporosis, reduce your risk of various cancers, and prevent you from developing dementia.
Therefore, there is little to no risk for men and women to eat moderate amounts of soy protein isolate as part of a healthy, balanced diet.
In this way, soy protein can be viewed as one more nutritional diet tool to help you meet your daily protein needs.
Soy vs Whey Protein
Because whey and soy have key differences in regards to content and nutritional value, it's important to understand these differences so that you can make the right choice for you.
Whey protein is useful for maintaining bone health, putting on body mass, and repairing muscles after an intense strength workout, which makes it a smart choice for a post-workout snack.
Though whey protein provides you with a good balance of amino acids and minerals, it comes from dairy, anyone that is lactose intolerant will struggle to be able to digest it. Other negative side effects can include gas and bloating, cramps, headaches, and general fatigue and exhaustion.

Soy protein is a great alternative protein source for anyone who is lactose intolerant or trying to cut down on their animal-based products. Though whey has long been considered the ideal protein for body building, the truth is that the key benefits of soy are almost equivalent.
Soy protein has been eaten by humans for over 5,000 years and is considered to be one of the highest quality plant-based proteins that nature provides. Each bean contains all the amino acids necessary for complete health.
The “feminizing” reputation of soy protein is largely unfounded, especially if you take the time to make sure your soy is sourced from high quality, organic sources.
The honest truth is that there is no right or wrong answer here. It's all about personal preference.
For best body building results, whey and soy protein should be used together.
Whey protein contains a large amount of branched-chain amino acids, while soy protein has high levels of arginine (a hormone that stimulates muscle formation) and glutamine (essential for workout recovery).
