I’ve been writing my blog now for a little over 12 years. In that time, I’ve covered a wide range of topics.

Surprisingly, I’ve never written about spirulina.

This is surprising because spirulina is often regarded as a super food and is used in all kinds of greens and antioxidant formulas.

Today, I want to talk about spirulina and show you why it is a great food to supplement with.

Adding it to your daily regimen will absolutely help give you an edge.

Spirulina’s Health Benefits (and Why They Matter)

Spirulina is a great product because it is both abundant and very easy to grow, so there’s no shortage of it for people who want to experience its benefits.

Below is a list of how powerful it is. You might enjoy taking it.

1 – Detoxes Heavy Metals (Especially Arsenic):

Spirulina’s bright blue-green pigment comes from phycocyanin, which is a compound with potent antioxidant and chelating properties.

Chelation is the process of binding heavy metals and then flushing them from the body.

One of the most compelling areas of research involves chronic arsenic poisoning, a problem in parts of Asia where well water is contaminated. A clinical study in Bangladesh found that combining spirulina with zinc significantly reduced arsenic levels in the body and improved symptoms in affected patients (PubMed).

Animal studies have shown similar effects with other metals like lead and cadmium, protecting liver and kidney tissue from damage (Journal of Pharmacy & BioAllied Sciences).

If you’ve ever wondered how to reduce your toxic burden, spirulina is a safe, food-based option to support the process—this and zeolites, which I’ve written about before.

2 – Can Help Fight Cancer

One of the most effective ways to fight cancer is through the use of antioxidants.

Spirulina contains compounds with demonstrated anti-tumor potential in lab and animal studies. Its antioxidant content helps reduce oxidative stress, a key driver in DNA damage and cancer cell development.

Some research has even looked at spirulina’s role in preventing oral precancerous lesions.

In one study, 45% of participants who took spirulina daily experienced complete regression of lesions, compared to 7% in the control group.

It’s not a magic bullet, but it’s a reminder that nutrient-dense foods can play a role in cancer prevention strategies.

3. Can Help with Better Blood Pressure

Spirulina appears to promote healthy blood vessel function and nitric oxide production, which helps blood vessels relax.

See my article on Circulation Syn3rgy to show you how that works.

Healthy blood vessel function can translate into lower blood pressure over time.

A review of clinical trials found average systolic blood pressure dropped by about 4.8 mmHg and diastolic by about 7.1 mmHg in participants taking spirulina (The Sun).

These reductions may seem modest, but even small changes can have significant cardiovascular benefits over decades.

4 – May Help Improve Cholesterol:

Spirulina has been shown to lower LDL cholesterol and triglycerides while boosting HDL (“good”) cholesterol. The effect is partly due to its antioxidant content and its ability to influence lipid metabolism in the liver.

One study combined spirulina with high-intensity interval training and saw improved lipid profiles and reduced waist circumference in overweight men (News Medical).

If you’re working on heart health, this is a safe addition alongside diet, exercise, and other lifestyle changes.

5- Boosts Exercise Performance:

Now I know that not everyone who reads these articles cares much about athletic performance. Still, for those who do, it’s worth noting that athletes may notice improved endurance and reduced fatigue with spirulina.

It seems to work by reducing oxidative stress from intense training and enhancing the body’s ability to use fat for fuel, sparing glycogen stores.

In a meta-analysis, spirulina supplementation improved antioxidant enzyme activity and reduced exercise-induced muscle damage (PMC). Many athletes also report shorter recovery times when using it regularly.

6- May Protect the Brain & Improve Memory:

I love being able to look at nature and use things that God created to help boost my mental power.

And spirulina’s antioxidant and anti-inflammatory compounds may help shield the brain from age-related decline, which is something we all want to avoid.

A few animal studies show it can reduce inflammation in the brain and improve memory and learning.

Some researchers suggest it could have a role in protecting against neurodegenerative conditions like Parkinson’s and Alzheimer’s, though human trials are still in early stages.

7- Manages Blood Sugar Levels:

Controlling your blood sugar and keeping it in the healthy range is easily one of the best ways to maintain excellent health.

Now, for people with insulin resistance or type 2 diabetes, spirulina may help stabilize blood sugar. In several studies, it reduced fasting glucose levels and improved hemoglobin A1C. (Health.com).

This benefit likely comes from a combination of its nutrient density, antioxidant action, and ability to reduce inflammation that contributes to metabolic dysfunction.

Teamed up with exercise and our Blood Sugar Syn3rgy, it could be a real help for people struggling with blood sugar control.

8 – Helps Manage Weight:

If you use it to manage your blood sugar, there’s a good chance it will also help with your weight.

While spirulina isn’t a standalone weight-loss tool, it can support weight management in several ways:

• Promoting satiety (it’s high in protein and nutrient-dense)
• Supporting a healthy metabolism
• Reducing inflammation linked to obesity

Combined with regular exercise, spirulina may help improve body composition and maintain energy levels without the crash you get from stimulants.

A Final Word on Spirulina

Spirulina isn’t just another trendy “superfood” to sprinkle in smoothies; it’s one of the most nutrient-rich foods we know of, with research-backed benefits for detoxification, cardiovascular health, metabolism, and more.

The key is choosing a high-quality, contaminant-free source, as low-grade spirulina can be tainted with heavy metals or harmful bacteria. Look for brands that are third-party tested and sourced from clean, controlled waters.

If you’d like, I can also put together a comparison of the best spirulina supplements so you can avoid the low-quality ones that often make it onto store shelves. We carry organic ones in our patient and online store.
