You’ve likely heard of protein powders, but what do they actually do? Protein powders are a powdered supplement that are often used to make protein shakes. They can be animal or plant-based protein, flavoured or unflavoured, and used in other things like baking or mixing into cereal. Here’s why people love protein shakes: 1) Can help with weight loss – slows down the digestive process and targets fat loss. 2) Can help build muscle – protein helps muscle rebuild and become stronger. 3) Are convenient – mixing a protein shake is simple and offers an easy way to boost your protein/nutrient intake.
