                                According to the NIH, nutrient degradation in powdered supplements can begin within 6-12 months of opening if not stored correctly, with factors like heat and humidity accelerating spoilage significantly. While greens powder is a convenient health booster, its effectiveness hinges on proper storage, and the need for refrigeration often depends on the specific ingredients and manufacturer instructions.
