How long can you keep the spirulina in the stored room?

Spirulina, when stored properly in a cool, dry place away from direct sunlight, can last for about 2 to 3 years. It's essential to keep it in an airtight container to prevent moisture and contaminants. Always check the expiration date on the packaging for specific guidance, as it can vary by brand. If it has an off smell or unusual color, it's best to discard it.
