Algae protein is a type of plant-based protein derived from algae, which is an aquatic organism. Algae are a rich source of essential nutrients, including protein, vitamins, minerals, and essential fatty acids. Algae protein is a sustainable alternative to animal-based proteins, such as whey and casein, and is often used to create plant-based meat alternatives. Algae protein also contains a high amount of fiber and is often used in vegan and vegetarian diets.
