According to nutritional experts, while unopened spirulina can last for up to two years, its potency begins to degrade significantly once exposed to air. Understanding how long does spirulina last after opening is crucial for preserving its potent nutritional benefits and ensuring you get the most out of this popular superfood supplement.

According to a study published in the *Brazilian Journal of Biology*, spirulina's antioxidant potential can degrade by over 50% in just 50 days when stored at room temperature. So, does spirulina lose its potency over time? The answer is a clear yes, though proper storage is key to extending its nutritional life.
