Pea protein powder can be mixed with liquids such as water, milk, or non-dairy milk alternatives such as almond milk, to create a smooth and creamy shake. To mix, simply add one scoop of pea protein powder to a glass or shaker bottle, add the desired amount of liquid, and shake well until fully combined. You can also add in other ingredients such as fruit, sweeteners, or nut butters for extra flavor and nutrition.
As for creating a complete protein source, pea protein powder alone is not a complete protein source as it is missing certain essential amino acids. However, it can be combined with other plant-based protein powders such as rice or hemp to create a complete protein source. The combination of different plant-based protein powders can provide all of the essential amino acids needed for optimal health and muscle recovery.
