If it hurts after eating, it is recommended to start with the following three methods.
1 Improvement reaction: Continue to eat without stopping for about half a month to see if it returns to normal. There are examples of pain caused by eating certain parts of the body, such as joint pain. It is related to the detoxification and recovery of this part of the body.
2 The problem of spirulina itself. (For example: inferior spirulina, feed-grade spirulina, fakes, manufacturers have added certain substances to improve the effect)
First check to see if it is a fake from a big brand, and then verify the spirulina yourself (For example, put it in the water to see the color and smell. These information are easier to find online) and judge the quality of spirulina.
3 Reaction with other commonly taken drugs.
The third possibility is less likely. You can check whether you are allergic to high protein. If not, it is also recommended that there should be a period of time between taking spirulina and medicines.
