Tag: Old protein powder

According to food scientists, dry, low-moisture foods like protein powder are less susceptible to bacterial growth than fresh foods. This means that while protein powder does have a shelf life, an old tub might not be unsafe immediately past its "best by" date. So, what happens when protein powder gets old, and how can you tell if it's still safe to use?

While many protein powders come with a "best-by" date of around two years, this does not mean they are necessarily safe to use three years later. The safety and effectiveness of aged protein powder depend on several factors, including storage conditions, ingredients, and any signs of spoilage.
