How long can you keep the spirulina in the cabinet?

Spirulina powder can typically be stored in a cool, dark place like a cabinet for about 1 to 2 years if kept in an airtight container. It's important to check the expiration date on the packaging, as exposure to light, heat, and moisture can degrade its quality over time. Once opened, it's best to consume it within a few months for optimal freshness. Always inspect for any off odors or changes in color before use.
