What is Walnut Protein?

Walnut protein is a plant-based protein extracted from the seeds of the walnut tree (Juglans regia). After the oil is removed from walnut kernels, the remaining press cake is processed into a fine protein-rich powder. Walnut protein is a complete protein, meaning it contains all nine essential amino acids, and is particularly rich in arginine and glutamine, making it a valuable ingredient for muscle recovery and overall wellness. Its smooth texture and mild, nutty flavor make it suitable for both supplements and functional foods and it is sometimes blended in bulk with almond protein or flaxseed protein to create fiber-rich powders.

Walnuts are typically harvested between late summer and early fall, depending on the region.
