According to the blog of Longevity Bird, protein, non-protein amino acids, physiologically active substances and other organic substances contained in pearls are almost surrounded by 24 times of insoluble calcium carbonate, and only a small part of them are exposed after grinding into fine powder, so many people think that pearl powder has no nutrition and only acts as a catheter after being absorbed by the skin.
However, according to the research records of experts on pearl powder of Longevity Birds, I know that the average particle size of pearl powder is as fine as 40- 100 nm, which has exposed most of the nutrients, which is by no means comparable to ordinary pearl powder. According to modern scientific research, pearls are rich in 18 kinds of amino acids (seven of which are essential amino acids for human body, that is, amino acids that must be ingested from the outside but cannot be synthesized by human body), more than 30 kinds of trace elements and rich vitamins. Therefore, pearl powder is of great help to human body. Specifically, you can go to official website, a longevity bird for consultation.
