When it comes to superfoods, spirulina has been making waves in the health and wellness community for years. But did you know that not all spirulina is created equal? In fact, there are two distinct types: blue spirulina and green spirulina. Let's dive into the world of these algae powerhouses and uncover the key differences between them.
The Basics: What Are Blue and Green Spirulina?
Both blue and green spirulina come from the same species of cyanobacteria, Arthrospira platensis. The main difference lies in their processing and the compounds they contain.
Green Spirulina
Green spirulina is the more common and traditional form. It's the whole algae, dried and powdered, retaining all of its natural components. This is what gives it its characteristic deep green color and strong, often polarizing taste.
Blue Spirulina
Blue spirulina, on the other hand, is an extract of the algae. It's made by isolating the pigment phycocyanin, which gives spirulina its blue-green color. This process results in a vibrant blue powder that's milder in taste and odor compared to its green counterpart.
Nutritional Profiles: How Do They Compare?
While both forms of spirulina are nutritional powerhouses, their profiles differ slightly due to the extraction process.
Green Spirulina
Green spirulina is known for its complete nutritional profile. It contains:
- High protein content (up to 70% by dry weight)
- All essential amino acids
- Vitamins, including B12 and beta-carotene
- Minerals like iron, magnesium, and calcium
- Chlorophyll
- Various antioxidants
A study published in the journal Marine Drugs noted that Spirulina is an important source of proteins, vitamins, minerals, and other nutrients and may be used to prevent certain diseases due to its therapeutic characteristics. Read the study
Blue Spirulina
Blue spirulina, being an extract, has a more concentrated amount of certain compounds:
- High concentration of phycocyanin
- Reduced content of other nutrients found in whole spirulina
- Lower calorie content
- No fishy taste or smell
Research has shown that phycocyanin, the main component of blue spirulina, has significant antioxidant and anti-inflammatory properties. A study in the journal Oxidative Medicine and Cellular Longevity stated, C-phycocyanin (C-PC) is a biliprotein found in spirulina that has been reported to exhibit antioxidant, anti-inflammatory, neuroprotective, and hepatoprotective effects.

Taste and Usability: A Clear Winner Emerges
One of the most significant differences between blue and green spirulina is their taste and ease of use.
Green Spirulina
Green spirulina has a strong, often described as "pond-like" or fishy taste. This can make it challenging to incorporate into foods and beverages without altering their flavor significantly. Many people find they need to mask the taste with strong flavors or consume it quickly in capsule form.
Blue Spirulina
Blue spirulina, on the other hand, is nearly tasteless and odorless. This makes it much easier to incorporate into a variety of foods and drinks without affecting their flavor. It's this quality that makes blue spirulina the star ingredient in products like BluWater, where you can enjoy all the benefits of spirulina in a refreshing, great-tasting drink.
Health Benefits: Two Paths to Wellness
Both forms of spirulina offer significant health benefits, though their specific advantages may differ slightly due to their composition.
Green Spirulina
Green spirulina's complete nutritional profile makes it a powerhouse for overall health. Its benefits include:
- Immune system support
- Potential anti-cancer properties
- Cardiovascular health improvement
- Blood sugar regulation
A comprehensive review in the journal Cardiovascular Therapeutics noted, the cardiovascular benefits of spirulina are primarily attributable to its hypolipidemic, antioxidant, and anti-inflammatory activities. Read the study
Blue Spirulina
Blue spirulina, with its high concentration of phycocyanin, offers more targeted benefits:
- Potent antioxidant properties
- Strong anti-inflammatory effects
- Potential neuroprotective benefits
- Liver health support
A study in the Journal of Medicinal Food found that phycocyanin from spirulina had significant antioxidant and anti-inflammatory effects. The researchers concluded, the results of the present study demonstrate that C-phycocyanin is a potent antioxidant and anti-inflammatory agent. Read the study
Environmental Impact: A Consideration for the Conscious Consumer
When it comes to environmental impact, both forms of spirulina are generally considered sustainable. However, the production of blue spirulina requires an extra extraction step, which may increase its environmental footprint slightly compared to green spirulina.
At BluWater, we've addressed this concern by implementing a highly sustainable production process. Our blue spirulina is produced using recycled CO2 and with 85% water recycling, minimizing our environmental impact while maximizing the benefits of this incredible superfood.
Choosing the Right Spirulina for You
Both blue and green spirulina offer significant health benefits and can be valuable additions to a balanced diet. The choice between them often comes down to personal preference and specific health goals.
If you're looking for a complete nutritional profile and don't mind the strong taste, green spirulina might be your best bet. However, if you're after the potent antioxidant and anti-inflammatory effects of phycocyanin and prefer a product that's easy to incorporate into your daily routine without affecting taste, blue spirulina, like that found in BluWater, could be the perfect choice.
Remember, the best superfood is the one you'll actually use consistently. With its neutral taste and powerful health benefits, blue spirulina makes it easy to make this superfood a regular part of your diet. Why not give BluWater a try and experience the benefits of blue spirulina for yourself?
