Phycocyanin Powder: The Important Source of Protein for Human Body

As one of the three main macronutrients in the human body (the others are carbohydrates and fats), protein, which accounts for about 20% of body weight, exerts significant influence on our body and energy supplying. The Academy of Nutrition and Dietetics recommends a daily intake of 0.8 grams of protein per kilogram of body weight, which means about 0.35 grams per pound.

Protein plays a vital role in the construction of bone and body tissues. It is involved in the renewal and metabolism of muscle, blood, bone, nerve, hair, and tissue. However, the role of proteins goes far beyond that. Proteins form the body’s immune system, help the body fight against foreign bacteria, and are responsible for clearing cancer cells that the body produces every day. Therefore, protein can improve the immune ability and anticancer effect of the human body.

Proteins are actually involved in every process of the cell, covering metabolism, immune response, oxygen delivery, cell repair, and blood cell formation. Face haggard, mental deficiency, poor resistance, slow metabolism, and malnutrition will occur if there is a lack of protein.

Protein is composed of amino acids which are closely related to life and various forms of life activities. A complete protein is reported to contain all nine essential amino acids. Our body can produce most of the amino acids needed to maintain health, but another nine amino acids called essential amino acids are excluded and only can be ingested through diet.

Animals and plants, such as meat poultry, fish, quinoa, and soybeans, are the primary sources of protein we usually intake and they provide all nine essential amino acids, according to the Institute of Medicine’s Food and Nutrition Committee.

However, consumers who pursue healthy life tend to exchange plant-based protein for animal protein as the calorie and fat content of animal protein are higher than that of plant-based protein. The lower content of saturated fat and higher content of fiber and essential nutrients in plant-based protein contributes to the hottest market trend of plant-based protein. Therefore, increasing the source of plant-based protein has more health advantages.

Plants, including fruits, beans, seeds, nuts, whole grains, and cereals, are rich in protein. What is worth noting is that although many plants provide protein, most plants do not provide all essential amino acids, throwing out a problem for most vegetarians.

Phycocyanin is a kind of plant-based protein, which contains many kinds of amino acids needed by the human body (essential amino acids account for 37.2% of the total). It is gradually attracting more and more attention from vegetarians and clinical research activities to use as a dietary supplement because of its high protein content. Phycocyanin is a crucial molecule extracted from spirulina existing in the form of phycocyanin powder or phycocyanin liquid. It is proved the critical part to regulate the synthesis of many essential enzymes required by the human body, inhibit the growth of cancer cells and promote the growth of human cells. Meanwhile, it is also capable of regulating the immune system of the human body.


As the only plant-based protein with color in nature, Phycocyanin powder is regarded as the natural blue food pigment and a critical protein source for vegetarians. It has been used as a substitute for synthetic therapeutic and nutritional products in recent years. Because of its environmentally friendly and other health-promoting effects, such as ant oxidation and enhancing immunity, Phycocyanin powder is increasingly used in the food industry, cosmetics industry, health care, and pharmaceutical industry.

Moreover, as more and more attention is paid to health and safety, it is expected that phycocyanin, the only plant-based protein with color and rich nutrition applications, will usher in a considerable growth demand in the future.

BINMEI has always been aware of the market prospect of phycocyanin powder and spirulina liquid. After decades of research on phycocyanin, BINMEI has mastered mature technology in the processing and extraction of phycocyanin powder. In order to break through the barrier of poor stability of phycocyanin to heat, light and acid, BINMEI has invested a lot in R&D and is committed to providing more green and safe phycocyanin powder for the consumers who pursuit health and safety and the majority of vegetarians.
