Can creatine still be consumed if it becomes damp and forms clumps?

Under normal circumstances, creatine that has absorbed moisture and formed clumps should not be consumed. The detailed explanation is as follows:

Creatine clumping is usually caused by inadequate sealing, which leads to moisture absorption. Once damp, creatine more readily absorbs moisture from the air, resulting in crystallization. This physical change may be accompanied by nutrient loss or oxidation, thereby affecting the effectiveness of the creatine. A damp environment also provides favorable conditions for microbial growth and reproduction, increasing the risk of bacterial contamination. Consuming such creatine may therefore lead to discomforts such as abdominal pain and bloating, or even gastrointestinal infections, posing a threat to health.

Creatine clumping may also indicate expiration or spoilage. As a nutritional supplement, creatine has a specific shelf life. During storage, if it is not properly kept in a dry, well-ventilated, and cool place or if it has exceeded its expiration date, the creatine may deteriorate. Spoiled creatine not only loses its effectiveness but may also produce harmful substances that endanger health. Therefore, creatine that has clumped and may have expired should not be consumed.

Creatine should be stored in a dry, well-ventilated, cool place, away from direct sunlight and high temperatures. Additionally, regularly check the condition of the creatine; if clumping or signs of spoilage are noticed, discontinue use immediately.
