Question

Past treatment situation and effect: Hello, experts, the spirulina has expired for a year and I feel it’s a pity to throw it away. What should I do? Thank you, experts!

Answer

I understand your feelings very well. Normally, whether it’s medication or health supplements, their appearance and efficacy can be guaranteed within the expiration date. Spirulina is a health supplement, and it’s the same. It is not recommended to consume expired spirulina because the active ingredients may have depleted, and there may be side effects. Health supplements or medications usually have a shelf life of 2 to 3 years. During storage, the effective components gradually deplete. Consuming spirulina that has expired by a year will be ineffective and may cause side effects, so it is not recommended to continue taking them.
