Whey protein is a high-quality protein derived from milk during the cheese-making process. It's a complete protein, meaning it contains all nine essential amino acids necessary for human dietary needs. Whey protein typically appears as a fine, off-white or cream-colored powder. It has a mild, slightly milky flavor and a smooth texture when mixed into liquids. Many people use whey protein supplements to help them build muscle, recover after exercise, and meet their daily protein requirements. Whey protein concentrates, isolates, and hydrolysates are different forms of whey protein supplements, each with varying protein percentages and processing methods.

Whey protein powder should be stored in a cool, dry place away from direct sunlight and moisture. Ensure the container is tightly sealed after each use to prevent clumping and maintain freshness. Storing it in the pantry or a cupboard is generally sufficient. Avoid storing it in the refrigerator or freezer, as condensation can lead to clumping and spoilage. Properly stored whey protein can last for several months, even beyond the expiration date, if it looks, smells, and tastes normal.
