While most protein powders are formulated with a shelf life of up to two years, consuming a product that is three years old poses significant risks beyond simple loss of potency. This guide explores why you should not eat 3 year old protein powder and how to identify signs of spoilage that indicate it's time to throw it out.

According to scientific research on dairy products, proteins and fats can undergo oxidative changes when exposed to light, suggesting that protein powder is, in fact, light sensitive. While the dry, shelf-stable nature of protein powder makes it less susceptible to immediate spoilage than fresh food, chronic exposure to sunlight and UV rays can gradually degrade its nutritional quality and sensory properties. This slow degradation process, known as photo-oxidation, affects the delicate protein structures and other nutrients, ultimately compromising the supplement's effectiveness and taste.
