Spirulina is packed with nutrients. A single tablespoon (tbsp), or 7 grams (g), of dried spirulina powder, contains:Trusted Source
Protein: 4 g
Thiamin: 14% of the Daily Value (DV)
Riboflavin: 20% of the DV
Niacin: 6% of the DV
Copper: 47% of the DV
Iron: 11% of the DV
2. Boasts powerful antioxidant and anti-inflammatory properties
The main component of spirulina is called phycocyanin, which is an antioxidant that also gives it its unique blue color.
Phycocyanin can help fight oxidative stress by blockingTrusted Source the production of molecules that promote inflammation and providingTrusted Source impressive antioxidant and anti-inflammatory effects.
3. May lower cholesterol and triglyceride levels
Spirulina can help lowerTrusted Source total cholesterol, low-density lipoprotein (LDL) or bad cholesterol, and triglycerides, while also increasing high-density lipoprotein (HDL) or good cholesterol, which are all risk factors for heart disease.
According to one reviewTrusted Source, spirulina was able to significantly improve these markers in people with metabolic syndrome and related disorders.

Bottom line
Spirulina is a type of algae that grows in fresh or salt water. It comes as a supplement, in tablet or powder form. People use it for its health benefits, as it is rich in nutrients and has antioxidant properties.
Spirulina is among the world’s most popular supplements. It is made from an organism that grows in both fresh and saltwater.
It is a type of cyanobacteriaTrusted Source, which is a family of single-celled microbes that are often referred to as blue-green algae. Just like plants, cyanobacteria can produce energy from sunlight via a process called photosynthesis.
Spirulina was consumedTrusted Source by the ancient Aztecs but became popular again when NASA proposed that it could be grown in space for use by astronauts.
These days, people use spirulina to boost the levels of nutrients and antioxidants in their bodies, and it may help protect against various diseases.
Here are 10 evidence-based health uses and benefits of spirulina.
1. Rich in many nutrients

Summary
Spirulina is a type of blue-green algae that grows in both salt and fresh water. It is highly nutritious and a great source of protein, copper, and B vitamins.
2. Boasts powerful antioxidant and anti-inflammatory properties
The main component of spirulina is called phycocyanin, which is an antioxidant that also gives it its unique blue color.
Phycocyanin can help fight oxidative stress by blockingTrusted Source the production of molecules that promote inflammation and providingTrusted Source impressive antioxidant and anti-inflammatory effects.
Summary
Phycocyanin is the main active compound in spirulina. It has powerful antioxidant and anti-inflammatory properties.
3. May lower cholesterol and triglyceride levels
Spirulina can help lowerTrusted Source total cholesterol, low-density lipoprotein (LDL) or bad cholesterol, and triglycerides, while also increasing high-density lipoprotein (HDL) or good cholesterol, which are all risk factors for heart disease.
According to one reviewTrusted Source, spirulina was able to significantly improve these markers in people with metabolic syndrome and related disorders.
Summary
Studies indicate that spirulina can lower triglycerides and improve cholesterol levels, which may support heart health.
4. Protects LDL cholesterol from oxidation
Fatty structures in your body are susceptible to oxidative damage. This is known as lipid peroxidationTrusted Source, a key driver of many serious diseases.
ResearchTrusted Source found that the antioxidants in spirulina may be particularly effective at reducing lipid peroxidation.
In fact, one small studyTrusted Source showed that spirulina supplementation was able to reduce exercise-induced lipid peroxidation, inflammation, and muscle damage in 17 rugby players.
