Chlorella For Gut Health And Immunity Support

It goes without saying that a healthy immune system is essential for a healthy life. Without the ability to rapidly respond appropriately to a variety of external and internal exposures, your health would certainly suffer. Your immune system is your body’s first line of defence against illnesses and it’s made up of a complex network of cells, tissues and organs found in a variety of locations including your skin, spleen, lymphatic system and, most significantly, your intestines.


There is a key system in your body that is critically important to insure a healthy immune system.  Did you know that the most important component of your immune system is found in your gut? As it turns out, gut health isn’t just about good digestion. It’s essential for your overall wellbeing.


The gut contains around 100 trillion microorganisms, including beneficial and harmful varieties. Most of them are bacteria, but also fungi, viruses and protozoa. Collectively, these make up what is known as our gut microbiome. Maintaining a healthy balance of microorganisms within the microbiome is crucial for overall health.


healthy gut microbiome is one with a high diversity of microbes, and more of the good type of bacteria than the bad. But when that balance is disturbed by factors such as a poor diet, illness or prolonged use of antibiotics and other medications or toxic substances,  the resulting disharmony — known as dysbiosis — alters the balance and favouring the bad  types.  This alteration makes the body more susceptible to comprised immunity.


In addition to the  gut microbiome, there are other components of your digestive system that play a role in immune health.   They include the intestinal epithelial layer which is the single cell layer that lines both the small and large intestine, where most digestive, absorptive and secretory processes occur. Then there is the local mucosal immune system which composed of  cells protecting  the mucosal barrier which lines the intestinal tract. (Wiertsema 2021)


Insuring a healthy gut is, therefore, essential to insure that your immune system is responding to pathogenic invaders from without and within.  Providing optimal nutrition, supporting the good gut microbiome to thrive, and being able to restore and maintain a healthy gut lining are key factors for supporting a healthy immune system.


Chlorella  – A Superfood for Gut Health


In the world of amazing plants, Chlorella truly deserves its title as a superfood.  This one-cell fresh water algae is a powerhouse of amazing nutrition. Its claim to fame as one of the most nutrient-dense foods on the earth, is truly well deserved.  This is especially important when it comes to insuring a vital immune system.  Your nutrient status is critical to support a health immune system.  A comprehensive range of essential nutrients are required to support the body’s immune defences.


Chlorella’s nutrient profile is most impressive.   It contains an amazing number of immune supporting nutrients which include; all the B-complex vitamins (including the most absorbable form of B12), zinc, iron, calcium, magnesium, potassium, phosphorus, selenium, iodine and omega-3 essential fatty acid. Chlorella also contains more than 50 percent of bio-available protein and all the essential amino acids. It is one of the few foods that naturally contain vitamin D. In addition, it has more beta-carotene than carrots and more than five times more chlorophyll than wheatgrass. The iron content of chlorella is particularly impressive and can provide up to 40 percent of your daily requirements. (Yamashita)


According to research published in the Nutrition Journal, chlorella consumption can improve natural killer cell activity and stimulate the necessary inflammatory responses needed to fight off infections.(Kwak, 2012)  In another study, chlorella supplementation was shown to increase antibody production in the body, which helps fight infections and prevent disease-causing pathogens from invading.(Otsuki, 2011)


Chlorella is also a rich source of carotenoids, lutein, and zeaxanthin. They are known as the “eye vitamins” helping to safeguard the eye’s macula by protecting it from damaging blue light (emitted from artificial lighting and digital devices). Studies have shown that both lutein and zeaxanthin can protect against age-related macular degeneration eye strain and fatigue, cataracts, and even help to prevent vision loss and blindness (Ryu 2014). However, the benefits of carotenoids also include the ability to naturally boost the immune system. Research has linked high carotenoid intake with strong immune function. And this is not only from provitamin-A beta-carotene, but also from lycopene. Thanks to their anti-inflammatory, anti-tumour, and chemoprotective properties, benefits of carotenoids also include the ability to fight off illness and infection, as well as deadly diseases like cancer (Okada, 2018)



Chlorella contains high amounts of chlorophyll, which the reason for its green color.  Chlorophyll helps purify and alkaline the blood and allows the body to utilise oxygen more efficiently.  It also supports a healthy immune system by eliminating many toxins such as mold and industrial pollutants. Among other things, research points out that chlorophyll stimulates red blood cells’ quality and quantity, (Ulbricht, 2014) supports healthy oxygenation, detoxifies the liver, boosts energy levels, cleans the digestive tract and is a powerful antioxidant that fights off free radicals.


When it comes to immune health, it is important to assist the growth of beneficial bacteria while reducing the presence of bad bacteria.  A study found that Chlorella helps to maintain gut health by actually increasing the numbers good bacteria while, at the same time, reducing the number of bad bacteria.(Jin, 2020)


There’s another gut-healthy fact about Chlorella.  Chlorella is a source of dietary fibre, A 2017 study found that the importance of fibre is intimately tied with the importance of your gut microbes. A proper fibre diet literally feeds and makes these bacteria thrive. In turn, they grow in number. The more microbes you have in your intestines, the thicker the mucus wall and the better the barrier between your body and your healthy bacteria population. While the mucus barrier lowers inflammation throughout the body, the bacteria aid in digestion, creating a dual benefit.(Zou, 2017)


Chlorella Growth Factor  for Immune Support


So what makes chlorella such a good immune booster? Research points to a special nucleic acid complex found in the plant called Chlorella Growth Factor, found only in chlorella.  Chlorella Growth Factor (CGF) is a unique complex found in the cell nucleus of chlorella. CGF is produced during intense photosynthesis which allows chlorella to grow so rapidly. CGF is a complex combination of key nutrients including amino acids, vitamins, essential fats and more. ((Abdolbaghian, 2021).


CGF has many extraordinary health benefits, especially for gut and  immune health.  It improves RNA/DNA functions responsible for the production of proteins, enzymes and energy at the cellular level, stimulating tissue repair and protecting cells from certain toxic substances. (An, 2016). CGF is easily absorbed by the intestines allowing for cellular regeneration. Since CGF generates rapid tissue repair, it strengthens the immune system well as helping to heal intestinal inflammation and leaky gut.


Chlorella Growth Factor provides another way to optimise immunity   It produces glutathione which plays a major role is gut health as well as  immune health.  Glutathione is a powerful molecule that supports the liver’s ability to  bind to heavy metals, solvents, environmental toxins, pesticides and all other metabolites and then converts these substances into a form that can be safely excreted in urine or bile. Glutathione enhances the functioning the immune system in another way.   It is an antioxidant that eliminates dangerous free radicals. (Ogawa, 2016)


Good gut health requires the growth of beneficial gut flora.  Chlorella Growth Factor has been shown to stimulate the growth of good bacteria as well as regulating a healthy intestinal flora environment. A Japanese study showed that due to its “rich supply of prebiotic food, Chlorella can actually triple the rate of growth of good bacteria in the gut”.  It showed increased immunity levels in mice who were fed CGF extracted from chlorella cells, The study concluded that CGF could be used as a “function food to enhance human′s immunity.”(Han, 2014)


It amazing to discover that this single-cell organism contains such dynamic benefits, not only  supporting your digestive system and immunity, but also overall health and wellbeing. The combined benefits from Chlorella’s comprehensive nutritional profile including Chlorella Growth Factor play an important role in enhancing all aspects of your life.


Be Sure you Choose the Very Best Chlorella


As Chlorella grows in popularity, the question inevitably arises about how to choose the very best chlorella product.  Chlorella is a freshwater algae that has evolved for millions of years in an environment with an abundance of clean water, fresh air and lots of sunshine.  Obviously, by providing these conditions, the chlorella will maintain its powerful healing properties.


Many companies are now growing chlorella indoors or in some form of artificial environment and sunlight.  The most potent chlorella is ideally grown in an outdoor environment where it can thrive, as Nature intended.
