The quality of protein in Spirulina is not bad, and its concentration is not low. However, as a health care product, Spirulina generally only ingests a few grams a day, providing even less protein-compared with the dozens of grams of protein needed by the human body a day, that point in Spirulina can be completely ignored.

Another example is "selenium-enriched tea". The selenium content in tea is indeed not low, but considering the daily use of tea and the dissolution rate of selenium in tea, the selenium it can contribute can only be described as "talking is better than nothing" relative to human needs. In fact, all kinds of magical health care products with "high nutritional content of XX" are basically the same.

Extended data:

Many ingredients similar to spirulina are not necessary for human body, but marketing often claims that "scientific research shows that it has certain effects." Most of these studies are just some cell experiments or animal experiments.

Cell test can provide some research directions, but it may be completely different from the situation in vivo. Moreover, it is impossible to draw the conclusion that "how much to eat is effective". The reference value of animal experiments is higher than that of cell experiments, but it is still far from people.

More importantly, these tests are often just to explore the mechanism of action. To apply them to the human body, "further tests are needed on the human body". Therefore, trusting these ingredients rashly may bring harm to the body.
