But what is chlorella, exactly? Why do people prefer to use this as a supplement? Read on to learn more about this incredible superfood.

What Is Chlorella Used For?


The chlorella plant is a supplement that brings many nutrients, proteins, and fiber to the body. As such, it has many possible health benefits people can enjoy when taken regularly.

But what is chlorella? It is a type of unicellular algae grown and harvested in freshwater bodies. This type of green algae has a tough cell wall, so it needs to be in supplement form for people to consume it.

Chlorella supplement is available in several forms, namely:

  • Dissolvable chlorella powder
  • Liquid extract
  • Tablets

The chlorella algae are native to Taiwan and Japan. While it was discovered in 1890, studies about its potential as a food source started in the 1940s.


Chlorella Pyrenoidosa V.S. Chlorella Vulgaris

Today, there are two types of chlorella supplements: Chlorella Pyrenoidosa and Chlorella Vulgaris.

As a nutritional supplement, Chlorella Pyrenoidosa contains more nutrients, and the presence of pyrenoidosa characterizes it. Compared to Chlorella Vulgaris, it has higher protein content, more Vitamin B12 content, and Chlorella Growth Factor.

Additionally, some studies have found that chlorella pyrenoidosa supplementation reduces a pregnant woman’s risk of suffering from iron deficiency anemia, proteinuria (high levels of urine in the body), and edema (swelling due to trapped fluid in body tissues). 

Chlorella Pyrenoidosa has thicker cell walls; when unprocessed, it is harder to digest. Luckily, chlorella supplement manufacturers have managed to break down this cell wall mechanically, chemically, or through fermentation, making it easy to digest and absorb by the body.

Additionally, the cell walls of some enzymes in Chlorella Pyrenoidosa must be broken down to get the algae’s full health benefits. Breaking down these cell walls must also not undergo heat, or the enzymes will lose potency.

Meanwhile, Chlorella Vulgaris has a cracked cell wall. Yes, this type is easy to digest but less potent than Pyrenoidosa. Vulgaris has less protein content and nutrient content in it. So, when it comes to supplementation, Chlorella Pyrenoidosa is the preferred strain.

This is why it is vital for anyone who wants to take chlorella supplements to check if they’re buying Chlorella Pyrenoidosa and a nutrient-dense formulation to ensure they’re getting the best.
