Kanna (Sceletium tortuosum) is gaining popularity as a natural mood-enhancer, especially for those seeking calm focus, reduced stress, or daily emotional wellness support. But if you’ve recently purchased Kanna—or rediscovered a half-used bag in your cabinet—you might be wondering:Does Kanna expire? And if so, how can you make it last longer?
While Kanna doesn’t “go bad” like fresh herbs, it can lose potency over time—especially if stored improperly. In this guide, we’ll explain how long Kanna products typically last, how to check if they’re still good, and the3 best ways to store Kanna to preserve freshness and effects.
Kanna can lose potency after 1–2 years if not stored in an airtight, cool, dark environment.
Faded aroma, dull color, and weak effects are signs your Kanna may have expired.
To maximize shelf life, store Kanna in airtight containers with desiccants and avoid heat and humidity.
Before diving into shelf life and storage, here’s a quick intro for anyone unfamiliar with Kanna:

Origin: Indigenous to South Africa, traditionally used for emotional resilience and social bonding

Kanna doesn’t always show visible signs of expiration, but there are clues to watch for:
Weaker aroma: Kanna has a strong earthy or slightly sour smell. If it's faint or musty, it may have lost strength.
Color change: A dull, grayish color can indicate degradation.
Weaker effects: If your typical dose no longer delivers the same impact, it may be time to replace it.

Air exposure breaks down the alkaloids that make Kanna effective. Keep your Kanna in asealed glass jar, a vacuum-sealed bag, or another airtight container.
Avoid using loosely sealed pouches or plastic baggies that can let in oxygen and moisture over time.
Heat and UV rays accelerate degradation. To preserve potency, store Kanna in:
A dark pantry or cabinet
A drawer in a cool, dry room
A sealed container away from direct sunlight
Avoid placing it near windows, appliances, or heat sources.
To fight humidity, toss in a food-safe desiccant packet—the kind found in supplement bottles. This helps preserve the powdery consistency and prevents mold, especially in humid environments.
For long-term storage:
Vacuum-seal bulk purchases
Freeze Kanna only if completely dry and sealed tight
Label and date your container when you open it

Still, even fermented Kanna should be stored properly to maintain its effects and safety profile. Learn more about its natural anxiety-reducing potential in this in-depth article.
Usually, no. If Kanna is stored in a dry, cool, and dark environment, it won’t grow dangerous bacteria or mold under normal conditions. But if your Kanna smells sour, has visible mold, or feels damp,don’t use it.
