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 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 It also contains small amounts of magnesium, potassium, and manganese. In addition, the same amount contains only 20 calories and less than 2 g of carbohydrates. Spirulina also provides a small amount of fat — around 1 g per tbsp (7 g) — including both omega-6 and omega-3 fatty acids in an approximately 1.5 to 1 ratio. Plus, the quality of the protein in spirulina is considered excellent and providesTrusted Source all of the essential amino acids that your body needs. Note that it is often claimed that spirulina contains vitamin B12, but this is false. It has pseudovitamin B12, which has not been shown to be effective in humans. 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. Summary Fatty structures in your body can become oxidized, driving the progression of many diseases. Some research suggests that the antioxidants in spirulina may help prevent this. 5. May have anti-cancer properties While more studies are needed, some evidence suggests that spirulina has anti-cancer properties. Research in animals indicatesTrusted Source that it may help reduce cancer occurrence and tumor size in various cancers. Summary Spirulina may have anti-cancer properties. However, more research is needed. 6. May reduce blood pressure One review of five studiesTrusted Source found that taking 1-8 g of spirulina per day could significantly reduce both systolic and diastolic blood pressure, especially for people with high blood pressure levels. This reduction is thought to be driven byTrusted Source an increased production of nitric oxide, a signaling molecule that helps your blood vessels relax and dilate. Summary Spirulina may increase production of nitric oxide and reduce blood pressure levels, a major risk factor for many chronic conditions. 7. Improves symptoms of allergic rhinitis Spirulina is a popular alternative treatment for symptoms of allergic rhinitis, and there is evidence that it can be effective. For instance, one studyTrusted Source found that spirulina was more effective than cetirizine, an antihistamine used to treat allergies, in improving symptoms of allergic rhinitis and decreasing inflammation. However, more research is needed. Summary Spirulina supplements may be effective against allergic rhinitis, but more research is needed. 8. Could be effective against anemia Anemia is fairly commonTrusted Source in older adults, leading to prolonged feelings of weakness and fatigue. A 2020 study found that taking spirulina may improve anemia in pregnant people during the second trimester. In 2021, researchersTrusted Source also found it may also improve iron deficiency in young children. However, more high-quality, recent studies are still needed. Summary Research suggests that spirulina may improve anemia in pregnant people, as well as iron deficiency in children. 9. May improve muscle strength and endurance Exercise-induced oxidative damage is a major contributorTrusted Source to muscle fatigue. Spirulina may help reduce this, as researchTrusted Source points to improved muscle strength and endurance. In another studyTrusted Source, spirulina supplementation was able to improve oxygen uptake during an arm cycling exercise, with researchers noting that it could act as an ergogenic aid to enhance athletic performance. Summary Spirulina may provide multiple exercise benefits, including enhanced endurance and increased muscle strength. 10. Could support blood sugar control Animal researchTrusted Source suggests that spirulina could help lower blood sugar levels. However, according to one review of eight studiesTrusted Source on humans, spirulina supplementation in doses ranging from 0.8-8 g daily could significantly reduce fasting blood sugar levels in people with type 2 diabetes. However, there was no significant effect on blood sugar levels after eating or levels of hemoglobin A1c, which is used Trusted Source to measure long-term blood sugar control. Therefore, more research is needed. Summary Some evidence suggests that spirulina may benefit people with type 2 diabetes by significantly reducing fasting blood sugar levels. Still, more studies are needed. Poster Comment: I already take spirulina twice a day. I will start taking Krill oil tomorrow.
