Soy Protein: Health and Nutrition Benefits

High-quality protein with proven health benefits

For over 50 years, we’ve worked with some of the world’s top researchers to drive the science that supports the benefits of soy protein ingredients. Along the way, we’ve also demonstrated the value of plant protein in a healthy diet.

Today, hundreds of published studies have used our SUPRO® Soy Proteins to support the nutritional quality and unique health benefits of plant-based proteins. These studies have helped many food companies develop and position nutritious foods and beverages

Soy protein is the only commercially viable plant-based source of high-quality complete protein. With a Protein Digestibility-Corrected Amino Acid Score (PDCAAS) of 1.0, it offers protein quality that’s comparable to dairy, eggs and meat. What’s more, it’s low in fat and saturated fat, and is free from cholesterol and lactose.

Let’s take a look at some of the health benefits of our soy protein:

Muscle health

SUPRO® Soy Protein provides the correct amount of essential amino acids for muscle maintenance and growth during exercise programs. Combining SUPRO® Soy Protein with dairy proteins (such as whey and casein) extends amino acid delivery and optimizes muscle gain from resistance training.

Heart health

SUPRO® Soy Protein has been shown to lower LDL cholesterol, total cholesterol and triglycerides, without lowering cardio-protective HDL cholesterol. On the strength of this evidence, 13 countries have approved heart health claims for soy protein.

Fullness and weight management

When used as part of a reduced-calorie, high-protein diet, SUPRO®Soy Protein has been proven to promote satiety and support weight loss. High protein diets based on soy protein have also been shown to preserve muscle during weight loss and improve the cardiometabolic profile of dieters.


How We Help

Plant Based

Our soy protein ingredients are derived from a reliable and sustainable raw material—the soybean. Soy protein is the most widely used source of plant protein in the food industry and among the most nutritious, versatile, economical and reliable sources of protein for food and beverage innovation.


Better Nutrition

Soy is a high-protein food that appeals to a broad consumer base in traditional markets such as sports nutrition and weight management. It provides healthy plant-based protein to growing children, teens, fitness enthusiasts, pregnant and lactating women, and active older individuals.



Soybean cultivation is highly efficient and requires less water than other irrigated crops such as corn. Producing soy protein requires far less land, energy and water than animal-based proteins. According to a third-party validated Life Cycle Assessment, our soybean isolate has a carbon footprint that’s up to 80 times lower than dairy and meat proteins.

Our soy protein supports at least six of the United Nations Sustainable Development Goals.
