Top 8 Benefits of Spirulina: Nature’s Ultimate Super Food

Written by Tim Skwiat

Health Benefits of Spirulina

It seems like the term “super food” gets thrown around a lot, leading you to believe there are single foods that can make or break your health and fitness. While most of these foods are indeed healthy and nutrient dense, the truth is they’re not the “magic bullet” you may have been led to believe.

Yet, there is a food worthy of such a lofty label: the “super sea vegetable” spirulina. Spirulina is a blue-green microalga (cyanobacterium) that naturally grows in high-salt alkaline water reservoirs in subtropical and tropical areas. It’s found in the United States, Mexico, Asia, Central Africa, and others. There are several different species, with the most researched being Spirulina platensis, Spirulina maxima, and Spirulina fusiformis.

As you’ll see, spirulina is supported by robust scientific evidence. The health benefits of spirulina are far-reaching, ranging from antioxidant protection to enhanced immunity to improved metabolic function to weight loss to increased energy levels to improved quality of life and more.

8 Health Benefits of Spirulina

1. Nutrient Powerhouse

Spirulina is regarded as “one of the most protective, healing nutritional ingredients in the 21st century” due to its nutrient profile and beneficial effects.1–3 It’s been consumed as a food by North Africans and Mexicans because it’s a rich source of nutrients, antioxidants, minerals, and vitamins, including:

  • High-quality protein (provides all the essential amino acids)
  • Vitamin B12
  • β-carotene
  • Tocopherols (vitamin E)
  • Potassium
  • Calcium
  • Magnesium
  • Iron
  • Zinc
  • Sodium
  • Phenolic acids
  • Essential fats including γ-linolenic acid

2. Powerful Antioxidant Properties

Spirulina contains several ingredients that have potent antioxidant activities, notably phycocyanin and β-carotene. A number of studies have shown that spirulina significantly improves antioxidant status and capacity.2,4

Why is this important? Researchers agree that a dynamic, healthy balance between levels of free radicals and antioxidant defenses is important for “optimal health.” Imbalances of free radicals and unhealthy levels of oxidants (relative to antioxidants) are commonly defined as “oxidative stress,” which plays a central role in biological aging and virtually all negative health outcomes.5,6 Thus, fortifying the body’s antioxidant defense system with foods like spirulina is incredibly important for overall health.

Not only is phycocyanin a powerful scavenger of potentially dangerous free radicals, it is also responsible for giving spirulina its blue-green pigment. In fact, a form of phycocyanin is used as a natural dye in food, cosmetics, and pharmaceuticals.3,7

3. Immunity and Detoxification

Not surprisingly (with the info above), Spirulina has been shown to have immune-enhancing effects. In two separate, randomized, controlled trials, a research group from Korea showed that spirulina use resulted in a significant rise in IL-2 (an anti-inflammatory cytokine) and a significant reduction in IL-6 (a pro-inflammatory cytokine).4,8 What’s more, researchers from Denmark showed that consuming spirulina for just one week enhanced the activity of Natural Killer cells, which play a crucial role in the body’s natural defense mechanisms.9

Spirulina has also been shown to increase the concentration of the body’s “master antioxidant” glutathione, bolstering the immune system and the body’s natural defenses against stress and dangerous toxins.10 Glutathione is most highly concentrated in the liver, which plays a vital role in detoxification.11 Speaking of the liver, the health benefits of spirulina have been shown to exert a “protective” effect on the liver.12

4. Heart Health

Several studies have shown that spirulina may have major cardiovascular benefits. In a systemic review with meta-analysis published in the journal Clinical Nutrition, researchers from Romania analyzed the outcomes of seven different randomized, controlled trials. They found spirulina significantly reduced total cholesterol, LDL (“bad”) cholesterol, and triglycerides while elevating HDL (“good”) cholesterol.3

What’s more, research has also shown spirulina may support normal blood pressure levels in healthy men and women.13 Together, these positive effects on blood fats and blood pressure highlight the potent heart health benefits.

5. Insulin Sensitivity, Metabolic Function, and Quality of Life

Spirulina has been shown to have multiple, strong beneficial metabolic effects. For instance, it’s been shown to improve carbohydrate management and glycemic (the effect of a food on blood sugar) control.14

One study published in the journal Nutrients found 100% of participants using spirulina for two months experienced improved insulin sensitivity.15 Meanwhile, researchers from Greece found similar insulin sensitivity benefits with 6 months of spirulina use, which also resulted in significant improvements in quality of life.12

6. Energy Levels

One of the most highly touted health benefits of spirulina is its effects on energy levels. Indeed, in a randomized, double-blind, placebo-controlled study, researchers from Ohio State University provided confirmation of this key attribute. After 8 weeks, participants taking spirulina demonstrated significant reductions in feelings of mental and physical fatigue.16

7. Exercise Performance and Recovery

Spirulina may also enhance athletic performance. In a study published in Medicine & Science in Sports & Exercise, the flagship journal of the American College of Sports Medicine, Greek researchers found spirulina significantly increased exercise performance (time to exhaustion).10

In a study published in the European Journal of Applied Physiology, researchers from Taiwan found that spirulina reduced muscle damage following intense exercise. What’s more, participants demonstrated improved time to exhaustion on a graded exercise test, suggesting improved performance and aerobic fitness.17

8. Fat Burning and Body Comp

Spirulina may also improve body composition: it’s been shown to significantly increase fat burning during exercise.10 Even more, spirulina supplementation for 6 months has been shown to reduce body weight by 8%.12

Where Can You Find Spirulina?

If you’re wondering where you can get your hands on spirulina without having to go on a deep-sea diving adventure, I don’t blame you. Since it’s not that easy to come by in food form, I recommend supplementation with spirulina.

While there are many great options available, here’s my top choice, which combines spirulina with another research-backed blend of superfoods called Spectra™ Total ORAC, which has been shown to combat oxidative stress, boost metabolism, and improve glycemic control.18

No matter how you look at it, with the laundry list of health benefits of spirulina, it is one of the few “superfoods” worthy of its lofty title.

Healthy Tip: Get Your Daily Dose of Fruits, Veggies AND Spirulina

While very few Americans enjoy the power of the superfood spirulina, did you know that over 220 MILLION Americans fail to get the recommended servings of fruits and vegetables each day, leaving their body in a dangerously deficient, inflamed and acidic state?

But, what if I told you can get 20 servings of high-quality, nutrient-rich fruits and vegetables (including your recommended daily amount of spirulina) in less than 30 short and enjoyable seconds a day…

Better yet, this brand new, amazingly delicious superfood elixir is so good that fitness professionals, nutritionists, moms and dads, and seniors alike—all over the world—are proclaiming as “the best-tasting greens product on the planet”…

    Hello Pam. Thank you for sharing your story. I would venture to say you aren’t the only person who purchases healthy foods with the best of intentions, only to end up either neglecting them, or tossing them when they are past their prime.

    With superfoods such as spirulina, which have a somewhat unusual taste, I have found the easiest way to include them in my healthy diet is similar to your recommendation of adding to smoothies and shakes. I think you have the right idea there, and I would love for you to share your smoothie recipes that incorporate spirulina, as I am always looking for new recipes.

    Much like you, I am also a lover of fruits and vegetables, and am mindful to get my daily dose of them. Even so, I still include a MetaboGreens 45X beverage every morning to ensure I get my fill, along with sneaking in some spirulina.

    Generally speaking I am a huge fan of including raw ingredients whenever possible, but knowing that I can get 20 servings of fruits and vegetables without any artificial ingredients or sugars added, this is one greens blend I know I can trust.

    I am happy to see that this article served as a friendly reminder to dust off your spirulina, and kick up your health a notch.

    Hello medgirl. I can appreciate your feedback, and you make some very valid points. As mentioned in the article above “It seems like the term “super food” gets thrown around a lot, leading you to believe there are single foods that can make or break your health and fitness. While most of these foods are indeed healthy and nutrient dense, the truth is they’re not the “magic bullet” you may have been led to believe.”

    In fact, deep health is the by-product of choosing high-quality, nutritious foods in appropriate amounts, creating a positive food environment, engaging in regular physical activity, practicing stress management, optimizing sleep hygiene and quality, adequately hydrating, and building and maintaining healthy relationships.

    In the following free report 14 Foods That Boost Your Thyroid, Coach Tim takes it one step further when he points out that “Indeed, there are a number of “Big Rocks” that go into the jar of getting (and staying) lean and healthy, and certainly one of those is regularly and consistently eating wholesome and nutritious foods. So while the promise of superfoods may be a little far-fetched, the guidance to eat more nutrient dense foods is not…”

    We appreciate your contributions, medgirl, and we hope you will enjoy exploring some of our other content.
