Spirulina is a kind of blue-green algae packed with nutrients.¹ Just one tablespoon of dried spirulina has 4 grams of protein. Plus, it’s got vitamins like thiamin, riboflavin, niacin, and minerals like copper and iron.¹ It also includes some magnesium, potassium, and manganese. This superfood only has 20 calories and less than 2 grams of carbs.²

Rich in Protein, Vitamins, and Minerals

Its protein is top-notch, offering all the essential amino acids.³ Spirulina packs a punch with B complex vitamins, beta-carotene, and vitamin E. Alongside these, you’ll find minerals such as manganese, zinc, copper, and selenium.³ It’s also rich in gamma linolenic acid, an important fatty acid. Sixty-two percent of its content is amino acids, making it a bona fide nutrient powerhouse.³

Ancient Superfood Consumed by Aztecs

The Aztecs valued spirulina for its nutrition. Now, it’s a go-to supplement for many.¹ You’ll often find Spirulina maxima from Mexico and Spirulina platensis from California.³ However, in the U.S., it’s mainly produced in controlled labs.³

For adults, a typical daily dose is 4 to 6 tablets, each 500 mg.³ It’s generally safe, even in high amounts. But, watch out for possible toxins.³

Spirulina and Its Antioxidant Properties

Spirulina is a blue-green algae famous for its strong antioxidant features. Its key part, phycocyanin, not just colors it blue. It also fights against oxidative stress and inflammation in the body.⁴

Phycocyanin: The Powerful Antioxidant

The phycocyanin in spirulina shows great antioxidant, anti-inflammatory, and brain-protecting effects.⁴ Studies show it can stop the making of inflammation-promoting molecules, offering protection against health problems.⁴

Fighting Oxidative Stress and Inflammation

Aside from its antioxidant power, spirulina also helps with the immune system and fights certain microbes. These qualities boost its fight against oxidative stress and inflammation.⁴ Its antioxidants are excellent at reducing lipid peroxidation, a cause of serious diseases.⁴

Spirulina’s many uses include being used in various food items and even as a bacteria growth inhibitor.⁴ Adding it to other foods boosts the total antioxidant power. This shows how beneficial it can be in a healthy diet.⁴

Scientists are finding new ways to get more phycocyanin from spirulina, such as freeze-thaw methods. This boosts both the amount and purity. The antioxidant benefits of this compound are well-proven, making spirulina a leading natural antioxidant.⁴

In summary, spirulina’s rich phycocyanin content makes it an antioxidant powerhouse. Researchers and health lovers are paying more attention to it. Its growth in popularity means more use and benefits are yet to be discovered.⁴

Spirulina for Heart Health

Studies show that spirulina can lower total and “bad” cholesterol and triglycerides. It can boost “good” cholesterol too. These are all big risks for heart disease.² A study discovered that taking 1 to 19 grams of spirulina daily for 2 to 48 weeks helped a lot. It improved these heart health markers in folks with metabolic syndrome and its related problems.² The key is spirulina’s anti-inflammatory and antioxidant powers.

Lowering Cholesterol and Triglycerides

The protein in spirulina is great at cutting how much cholesterol your body absorbs.² Also, the phycocyanin in it can lower triglycerides, which helps against heart disease, diabetes, and pancreatitis.²

Improving Blood Lipid Profiles

Adding spirulina to your diet won’t add to your weight and won’t affect your blood fats, sugars, or how well your liver and kidneys work.⁵ It can actually boost AMPK, which helps your blood fats stay healthy.⁵

Reducing Risk of Cardiovascular Disease

In a heart attack situation, spirulina made a big difference. It cut down the area damaged by the heart attack by 64%. And it increased the heart muscle saved by 18%.⁵ Heart function was also 30% better after taking spirulina compared to not taking it.⁵ This hints that spirulina could lower the danger of heart problems.

Anti-Cancer Potential of Spirulina

More studies are still needed, but spirulina shows promise in fighting cancer. In tests on animals, it seemed to lower cancer risks and shrink tumors from various kinds of cancer.⁶ The antioxidants and anti-inflammatory parts in spirulina, including phycocyanin, might be behind its anti-cancer effects. They seem to block tumor growth and kill cancer cells.⁶

Inhibiting Tumor Growth

Studies have looked into whether spirulina can stop tumor growth. In one, the special parts from Spirulina platensis were good at stopping liver cancer cell growth.⁷ A different study found that Spirulina with extra selenium made breast cancer cells stop dividing and die.⁶

Killing Cancer Cells

Besides halting tumor growth, spirulina’s properties might also destroy cancer cells. Some parts in spirulina, like gamma-tocotrienol and delta-tocotrienol, can make breast tumor cells die.⁶ Also, tocotrienols from palm, like those in spirulina, have stopped breast cancer cells from growing and helped make a helpful substance called interleukin-24.⁶

Spirulina for Blood Pressure Management

blood pressure

Spirulina is blue-green algae full of nutrients. It does wonders for your blood pressure. Researchers have found that 1-8 grams a day can lower both high systolic and diastolic blood pressures.¹

Promoting Nitric Oxide Production

This health benefit might be due to an increase in nitric oxide. This special molecule helps blood vessels relax and open up.¹ Spirulina is also good at reducing damage and stress on the heart’s blood vessels.⁸ So, by boosting nitric oxide levels, spirulina not only helps with blood pressure but also lowers the risk of some chronic diseases.

Relaxing Blood Vessels

Further studies show that spirulina can make blood vessels less stiff. For people with high blood pressure, this could be a big help.⁹ A small research on 48 patients found that adding spirulina to a salad dressing twice a day cut their blood pressure down.⁹

In another study, taking 4.5 grams of spirulina daily for 12 weeks dropped the systolic blood pressure of hypertensive patients.⁹ In Mexico, adding spirulina to the diets of patients with pre-hypertension to stage 2 hypertension also decreased their blood pressure.⁹ The effects were stronger in younger people.⁹

Although ongoing research is important, the current findings are exciting. They point to spirulina as a good addition for managing high blood pressure, especially in those with hypertension.¹⁸⁹

Alleviating Allergic Rhinitis

Spirulina is known to help with allergic rhinitis symptoms. There’s solid evidence backing its effectiveness. In one study, it outperformed cetirizine, an antihistamine, in easing symptoms and lowering inflammation.¹⁰ It does this by fighting inflammation with its antioxidants, reducing stuffiness, sneezing, and itching. This makes spirulina a promising alternative to common allergy meds.¹⁰

Reducing Inflammation and Symptoms

Allergic rhinitis is becoming more common worldwide and affects a lot of people. Yet, we still struggle to control it well with existing methods.¹⁰ Spirulina can make a big difference, as shown by studies where it eased symptoms like a runny nose, sneezing, and itchiness better than a placebo did.¹⁰ Research reveals that spirulina is indeed effective for allergic rhinitis. Still, more studies are needed to fully understand how it helps.¹⁰

Alternative to Allergy Medications

There’s evidence that spirulina could be a good choice over traditional allergy drugs for managing allergic rhinitis. In a study with 53 people from 8 to 58 years old, it was found that symptoms like a runny nose and bad smell got a lot better.¹¹ Their sleep, day-to-day work, and social life improved, too, after trying spirulina.¹¹ The study also warned about potential serious side effects of standard allergy meds, raising spirulina as a safer option.¹¹

Up to 30% of people with nasal symptoms might have allergic rhinitis. It affects one in six individuals.¹² In two clinical trials, involving 215 patients in total, spirulina was found to be good at easing allergic rhinitis symptoms. This means it could lower symptoms like a runny nose and bad smell.¹² Spirulina achieves this through C-phycocyanin, which fights inflammation and works as an antioxidant.¹² However, the studies remind us to take the findings with care, as evidence is still limited and more research is needed.¹²

Boosting Immune System Function

Spirulina is packed with vitamins and minerals that are good for keeping our immune system strong. It contains vitamins E, C, and B6.¹³ Studies have shown that taking spirulina can increase the number of white blood cells and antibodies.

But, we need more studies to be sure about its effects in people.¹³

Enhancing White Blood Cell Production

Researchers have looked into how spirulina can change our immune system.¹³ A study by Juszkiewicz and his team in 2018 used spirulina on rowers to see its effect.¹³ They found interesting results. Another study, by R. Baker and others in 2017, noticed that elite athletes who do a lot of cardio had lower white blood cell counts.¹³ These suggest spirulina might be good in boosting white blood cell numbers, which is crucial for a strong immune system.

Fighting Viruses and Bacteria

The antioxidant and anti-inflammatory factors in spirulina might help fight off diseases.¹³ A study in 2009 looked at how spirulina helped athletes’ immune systems.¹³ Then, in 2021, a study on football players showed spirulina made their immune systems recover faster after matches.¹³ These results led experts like Walsh and Mathews N.M. in 2018 to suggest spirulina for athletes to keep their immune systems strong.¹³

Spirulina doesn’t just boost white blood cells. It may also fight against specific viruses and bacteria.¹³ Lab studies have shown it might help with herpes, the flu, and HIV. However, we need more research to confirm this in humans.¹³

Spirulina for Anemia and Iron Deficiency

Anemia often causes weak and tired feelings in older adults.¹⁴ A 2020 study showed spirulina might help anemia in pregnant people at the second trimester.¹⁵ Also, a 2021 study found it could improve iron deficiency in kids.¹⁵ Spirulina’s high iron, from 28.5 to 100 mg, is thought to do this.¹⁵ This makes spirulina a good option for anemia and low iron levels.

In developing countries, about 80% of pregnant women have anemia. In Indonesia, it’s about 40%.¹⁵ Anemia goes up from 20% in the first trimester to 70% later in pregnancy.¹⁵ Spirulina can help with anemia in the second trimester. This is shown by an increase in hemoglobin levels.¹⁵

In Indonesia, a study looked at pregnant women taking spirulina or iron for eight weeks. The spirulina group had a big jump in hemoglobin levels (p=0.001). The iron group didn’t improve much (p=0.142).¹⁵ The women taking spirulina went from 10.16 to 13.60 in hemoglobin.¹⁵ The study showed no big difference in the groups’ other details. It was about things like age, education, job, health coverage, and pregnancy stage.¹⁵

Spirulina stands out because of its rich iron and other nutrients. It’s a hopeful choice for anemia and low iron, especially for older adults and pregnant women.¹⁴¹⁵
