As we continue through 2025, many fitness enthusiasts are focusing on maximizing the benefits of their protein supplements. Protein powder remains a staple for anyone looking to build muscle, improve recovery, or supplement their diet. However, it’s crucial to understand the shelf life of protein powder to ensure safety and effectiveness. So, how long does protein powder last after opening?
Once opened, most protein powders maintain their quality for about 9-12 months. However, this can vary based on the type of protein powder, storage conditions, and whether it contains additional ingredients or preservatives.
Trust your senses. If your protein powder has a strange smell, has clumped together, or tastes off, it’s best to discard it. Proactively checking your powder ensures you don’t consume anything that could impact your health negatively.
