Isolate protein is a highly refined form of protein powder that is derived from various sources, such as whey, soy, or pea. What sets isolate protein apart from other protein supplements is its purity and concentration. Typically, isolate protein powders contain 90% or more protein content, with minimal fats, carbohydrates, and lactose. This high level of refinement results in a product that is easily digestible and quickly absorbed by the body, making it an ideal choice for fitness enthusiasts and athletes alike.
