With 0.5–1g of fat and 1–2g of sugar per serving, it can fit into a variety of daily nutrition goals. Mix one scoop (33–34g) with 8–14 fl oz of cold water, milk, or another beverage. Stir, shake, or blend until dissolved. Enjoy 30–60 minutes before bed or anytime to help increase your daily protein intake as part of a balanced diet and exercise program.
