Does Spirulina go bad?
Yes, Spirulina goes bad. Fresh Spirulina goes bad like fresh vegetables. It withers, becomes discolored, or even becomes moldy if kept under poor storage conditions.
Spirulina powder is no different. It can go bad if moisture gets to it. Moisture results in the formation of mold. Moldy Spirulina should be discarded right away as it can lead to food poisoning upon ingestion.
How long does Spirulina last?
The shelf-life depends on whether the spirulina is fresh or in powder form. The fresh stuff, with a higher water activity, naturally has a shorter shelf-life.
An unopened package of Spirulina powder lasts about 2 years if stored correctly. Once opened, it should be kept no longer than 3 months. Fresh Spirulina, stored in the fridge continuously after harvest, lasts about 21 days. Do not be surprised if it goes bad before 21 days.
How to store spirulina?
Fresh spirulina should be kept in an air-tight container in the fridge. Spirulina in powder form can be kept in a cool, dark, and dry place, away from direct or indirect sources of heat.
The pantry or a kitchen cabinet are good places for storing Spirulina. Moisture and heat are the worst enemies of powdered Spirulina. If you opt for the kitchen cabinet, make sure the heat from the stovetop does not get to Spirulina.
What is Spirulina?
Spirulina is a food-grade blue-green alga that grows naturally in freshwater and saltwater. Commercially produced spirulina is a key ingredient in some food items and supplements.

What are the side effects of Spirulina?
Potential contamination with toxins
Wild spirulina grows in water bodies that are frequently contaminated with heavy metals, bacteria, or microcystins. The production of Microcystins is a part of the defense mechanism of Spirulina against predators. Ingestion of microcystins above the threshold level can be toxic.
The toxic effect of microcystin is prominent on the liver. Scientists have been finding ways to purify Spirulina of these toxins or produce toxin-free Spirulina in the lab.
May worsen the autoimmune conditions
Although Spirulina strengthens your immunity, the effects of Spirulina can backfire if you have an autoimmune disorder such as lupus, multiple sclerosis, and rheumatoid arthritis.
In this special scenario, Spirulina strengthens the very threat, that is the immune system, against the body cells. This results in weak muscles and damaged skin. Steer clear of Spirulina and other algae supplements if you have an autoimmune disorder.
