What Is Chlorella Vulgaris and How Does It Compare to Chlorella Pyrenoidosa?
Share
When researching chlorella supplements, you may come across two common species: Chlorella vulgaris and Chlorella pyrenoidosa. While both are nutrient-rich freshwater algae, they have some important differences that can affect how your body absorbs and benefits from them.
In this article, we'll explore what makes each species unique—and why Sun Chlorella chooses Chlorella pyrenoidosa as its core ingredient.
What Is Chlorella Vulgaris?
Chlorella vulgaris is a green microalga that has been widely studied for its nutritional benefits. It's known for its relatively thin cell wall, which makes it easier to digest than other species of chlorella. Many supplements on the market use vulgaris because it's easier and cheaper to process.
It contains:
- High levels of chlorophyll
- A range of vitamins and minerals
- Antioxidants and fiber
- Some Chlorella Growth Factor (CGF), though at lower levels than other species
What Is Chlorella Pyrenoidosa?
Chlorella pyrenoidosa is another variety of green algae, and it’s the species used in Sun Chlorella® products. It has a thicker, more resilient cell wall, which helps protect its rich nutritional content. This species is especially known for its high CGF (Chlorella Growth Factor) content—compounds that may support cellular regeneration and immune health.
However, because of the tough outer cell wall, it requires special processing to make its nutrients bioavailable. Sun Chlorella uses a proprietary Dyno®-Mill process to break the cell walls without using heat or chemicals, preserving nutritional quality and increasing digestibility.
Benefits of Chlorella Vulgaris
Chlorella vulgaris offers a wide range of health benefits, which is why it’s commonly used in many green supplements. Some of the key benefits include:
- Detoxification support: Helps bind to toxins and heavy metals to support natural detox processes
- Rich in chlorophyll: May help neutralize internal odors and support cellular health
- Immune support: Contains antioxidants, vitamins, and minerals that contribute to immune function
- Supports digestion: Its fiber content may aid regularity and gut health
- Natural energy booster: Thanks to its combination of B vitamins and iron
Because it’s naturally easier to digest, chlorella vulgaris can be effective for people new to green supplements or those looking for a basic nutritional boost.
Benefits of Chlorella Pyrenoidosa

Chlorella pyrenoidosa, the species used in all Sun Chlorella® products, delivers the same core benefits—but with a more potent profile:
- High CGF content: Unique to chlorella pyrenoidosa, Chlorella Growth Factor supports cell repair, regeneration, and overall vitality
- Superior detox power: Its tougher cell wall enhances its ability to bind to heavy metals and pollutants
- Immune and antioxidant support: Richer in antioxidants like lutein and beta-carotene, with stronger immune-modulating properties
- Supports gut health: May help rebalance the microbiome and improve digestive efficiency
- Skin and anti-aging benefits: CGF and chlorophyll work synergistically to support skin regeneration and reduce signs of oxidative stress
Combined with Sun Chlorella’s Dyno®-Mill processing technology, these benefits are delivered in a highly absorbable and scientifically validated form.
Key Differences Between Chlorella Vulgaris and Pyrenoidosa
Feature | Chlorella vulgaris | Chlorella pyrenoidosa (Sun Chlorella) |
---|---|---|
Cell wall thickness | Thin | Thick |
Natural digestibility | Moderate | Low (requires processing) |
CGF content | Lower | Higher |
Nutrient density | High | Very high |
Processing required | Often not required | Yes (Sun Chlorella uses Dyno®-Mill) |
Common use in supplements | Widely used | Used in premium-grade chlorella products |
Which One Is Better for You?
It depends on your goals and priorities:
- If you’re looking for a budget-friendly green superfood with basic benefits, Chlorella vulgaris may be suitable.
- If you want maximum nutritional value, a high CGF content, and scientifically backed digestibility, then Chlorella pyrenoidosa is the superior option.
That’s why Sun Chlorella uses only Chlorella pyrenoidosa, carefully processed to make it highly absorbable—without compromising its nutritional profile.
