Spirulina overview

What is spirulina
Spirulina is a kind of microalgae. People call it blue-green algae because of how it looks and its color. It belongs to a group called Arthrospira. There are 23 types that scientists have approved in this group. Spirulina grows in lakes with a lot of alkaline and high pH. These places are found in South Africa, Mexico, and northern Australia. Farmers grow spirulina in open ponds that copy these natural places. This way, they can make a lot of spirulina for food and supplements.
Did you know? Spirulina can live in tough places where most other microalgae cannot. This makes it a good choice for making food in a way that does not harm the planet.

Spirulina’s nutritional profile
Spirulina is special because it has a lot of protein. Dried spirulina has about 57% protein. This is more than most other microalgae. The protein gives you all the amino acids your body needs. Spirulina also has carbohydrates, fats, vitamins, and minerals. These nutrients help make spirulina a superfood.
Nutrient | Per 100g |
|---|---|
Energy | |
Fat | 0.2 g |
Carbohydrate | 8.0 g |
Fibre | 8.4 g |
Protein | 62.8 g |
Salt | 0.128 g |
Vitamin A | 1248 µg |
Vitamin K1 | 8050 µg |
Riboflavin | 0.86 mg |
Vitamin B6 | 0.72 mg |
Folic Acid | 94 µg |
270 mg | |
Iron | 57 mg |
Manganese | 5.7 mg |

You get a lot of protein, healthy fats, and vitamins like B12, A, and E from spirulina. It also gives you minerals such as iron, calcium, magnesium, and potassium. Spirulina has pigments like chlorophylls and carotenoids too. Your body can use these nutrients easily because they are very bioavailable. Growing spirulina in farms helps keep the quality and amount the same. This is why people call spirulina a superfood and why microalgae are important for nutrition. Spirulina helps feed people around the world and gives a protein source that is good for the planet.
Microalgae like spirulina give you protein.
Growing spirulina helps make more supplements.
Microalgae have a lot of protein and important nutrients.
What is phycocyanin

Phycocyanin in spirulina
Phycocyanin is the main blue pigment in spirulina. It makes up about 15-25% of spirulina’s dry weight. You can see its bright blue color in spirulina powder or supplements. This pigment is part of a group called phycobiliproteins. These pigments help spirulina use light for photosynthesis. The table below shows how the pigment works:
Component | Description |
|---|---|
Type | Pigment-protein complex from the phycobiliprotein family |
Structure | Composed of alpha and beta subunits with linear tetrapyrrole chromophores |
Function | Accessory pigment in photosynthesis, absorbs orange and red light, transfers energy to chlorophyll |
Color | Characteristic light blue color |
Absorption Peak | Absorbs light at approximately 620 nm |
Emission Peak | Emits fluorescence at about 650 nm |
Aggregation | Forms clusters called phycobilisomes, which adhere to the membrane |
The pigment takes in orange-yellow light and gives energy to chlorophyll. This helps spirulina grow and make more cells. The pigment is also used as a natural food color in many products.
To get phycocyanin from spirulina, people use different methods. Some ways are pulsed electric fields, high-pressure processing, freeze-thawing, and bead milling. Glycerine maceration is another way that keeps the pigment safe for food. Each method changes the purity and quality of the pigment. If you want good pigment for supplements or foods, you need to focus on c-phycocyanin extraction.
C-phycocyanin and its properties
C-phycocyanin is the main type of phycocyanin in spirulina. It has strong effects that help your body. Scientists have studied phycocyanin and found many health benefits. The pigment works as an antioxidant, anti-inflammatory, and immune booster. The table below shows some bioactive properties:
Bioactive Property | Effect |
|---|---|
Antioxidant | C-phycocyanin enhances serum SOD and catalase activity, surpassing vitamin E. |
Anti-inflammatory | C-phycocyanin reduces COX-2 and PGE2 expression in activated macrophages. |
Immunomodulatory | C-phycocyanin suppresses pro-inflammatory cytokines like TNF-α and IFN-γ. |
Cytokine Regulation | Enhances anti-inflammatory cytokines such as IL-10 in a concentration-dependent manner. |
The pigment helps your body fight stress and swelling. These functions make phycocyanin good for your health. It is important to know about c-phycocyanin purification. This step removes other pigments and makes the blue pigment pure for supplements and foods. When you pick spirulina products, choose ones with high c-phycocyanin and good purification. This helps you get the best health benefits.
