Cracked Cell Chlorella - Why Pulverized Chlorella is Better than Broken

What are the different types of chlorella and how do they differ? By Marisela Corrado

Sun Chlorella has brought the best chlorella supplements to the market since 1969. Chlorella is a single-celled, green, freshwater algae, and it’s packed full of nutrients. Similar to spirulina, one of the few differences is that chlorella is a single-cell algae with a nucleus, while spirulina is a multi-celled plant. Overall, chlorella may contain greater potential benefits than spirulina. Chlorella has one of the highest natural concentrations of chlorophyll, it’s a good source of Vitamins A and D, and it has one of the only known natural plant sources of Active Vitamin B12. Chlorella contains a component called Chlorella Growth Factor (CGF), which contains nucleic acids that may help to repair and rebuild cells. How it’s grown and processed makes a difference in how to access these health benefits.

Preparation Methods

Chlorella contains excellent nutrients within its tough cell wall. Breaking through this hard barrier provides the key to fully accessing chlorella’s potential. Here are three methods of preparation:


One lesser-known approach on the market is fermenting chlorella. Fermented chlorella is grown in a sealed, sterilized, fermentation tank in the absence of sunlight. This isn’t a practical solution since CGF is produced during photosynthesis. Instead of the fermented chlorella producing nutrients from the sun, it comes from a mixture of acetic acid and glucose, which isn’t nearly as natural or effective. 

Because the chlorella is fermented, it has to be heated to kill any bacteria that may be growing there. Superheating chlorella to over 120º essentially kills what little nutrients remain in fermented chlorella.

Cracked or Broken

Another type of chlorella available is cracked or broken cell wall chlorella. While fermenting chlorella softens the cell wall, it needs to be broken, in order to access the minerals and vitamins inside. Some companies are able to crack the cell wall of chlorella through sound vibrations. While this is better than fermented chlorella, it still isn’t the most effective way to access the impressive nutrition packed inside a chlorella cell.


The best way to access all the nutrients contained within chlorella is to pulverize the cell wall. Instead of softening or cracking the cell wall, it is pulverized, essentially eliminating most of the cell wall, giving your body easy access to the nutrition within. Pulverized chlorella provides the highest digestibility and nutrient absorption rate of other prepared methods.

Pulverizing chlorella is very similar to milling wheat, which leaves all the nutrients available at peak levels for maximum absorption. At Sun Chlorella, we pulverize the cell wall using DYNO®-Mill, which is a high-energy grinding mill designed to grind down to its particles.

There’s no addition of heat to kill any micronutrients, making the nutrients easily available. You can take pulverized cell wall chlorella in tablets or powder-form.

What is Chlorella?
Chlorella pyrenoidosa contains CGF which provides support for tissue renewal and immune health. Chlorella pyrenoidosa is considered to be beneficial.


Chlorella contains a high concentration of chlorophyll. Chlorophyll has history of internal purification.

Chlorella is the planet’s natural gift to us!
