About Soy protein isolate

Soy protein isolate is a highly refined form of soy protein extracted from soybeans. Originally produced in East Asia where soybeans are a dietary staple, it has become globally popular for its high protein content and versatility. Containing about 90% protein by weight, it is low in fat and carbohydrates, making it a popular choice for athletes and those seeking plant-based protein sources. It is also cholesterol-free and contains essential amino acids necessary for muscle repair and growth. Soy protein isolate is commonly used in protein powders, meal replacements, and a variety of plant-based products in modern global cuisine.

Health Benefits

• Supports muscle repair and growth due to its high protein content (approximately 27 grams of protein per 30-gram serving).
• May promote heart health by potentially lowering LDL cholesterol levels, as soy protein has been shown to reduce cholesterol when consumed as part of a diet low in saturated fat (FDA-approved health claim).
• Rich in iron (approximately 8mg per serving), which supports red blood cell production and helps prevent iron deficiency anemia.
