What Is Protein Powder?
Protein powder is made from different sources. Common types include whey, casein, soy, and pea protein. These powders are dry and easy to mix with water or milk. They help people get enough protein in their diet.
Because protein powder is dry, many think it lasts forever. But that is not true. It can expire and lose quality.
How Long Does Protein Powder Last?
The shelf life of protein powder depends on many things. It depends on the type of protein, how it is stored, and the packaging.
Most protein powders have a best before or expiration date printed on the container. This date tells you how long the powder stays good. Usually, protein powder lasts between 1 to 2 years if unopened.
Once you open the container, the powder can last for 3 to 6 months. But this depends on how you keep it. If you store it well, it can last longer.
What Happens When Protein Powder Expires?
When protein powder expires, several things can happen:
Change in taste: The powder may taste bitter or strange.
Change in smell: It may smell sour or off.
Clumping: Powder may become hard or form lumps.
Loss of nutrition: Protein quality may decrease.
Possible growth of bacteria or mold: This is rare but can happen if stored badly.
Using expired protein powder is not recommended. It may upset your stomach or cause other problems.
How to Store Protein Powder Properly?
Proper storage helps protein powder last longer. Here are simple tips to store your powder:
