Is Chlorella Good for Gut Health?
I have analysed several scientific studies and the general consensus is that "Chlorella could be a very useful supplement for people looking to improve gut health", there is also evidence to show that it can help manage chronic gut inflammations such as Crohn's disease and ulcerative colitis. I recommend readers to review "References and Further Reading" at the bottom of this article - here I have provided links and a brief summary of all of the relevant scientific studies.
I strongly recommend (especially if people have existing autoimmune diseases) to first consult with a healthcare professional before making significant changes to your diet, and please start slowly and in small does when introducing new supplements to your body.
Lets now explore how chlorella can be good for gut health.
1. Optimisation of Gut Microbiota:
Chlorella has been shown to significantly influence the composition of the gut microbiota, a key aspect of digestive health. The gut microbiota consists of trillions of microorganisms, including bacteria, viruses, fungi, and other entities, which play a crucial role in digestion, metabolism, and immune function.
Influence on Microbial Composition: Chlorella supplementation has been observed to alter the gut microbiota by increasing the population of beneficial bacteria. Studies indicate that Chlorella can promote the growth of bacteria that produce short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate. These SCFAs are produced through the fermentation of dietary fibres by gut bacteria, and they serve as a primary energy source for colon cells, strengthen the gut barrier, and regulate the immune system.
Enhancement of SCFA Production: The increased production of SCFAs not only helps in maintaining the integrity of the gut lining but also plays a pivotal role in protecting against pathogens and reducing the risk of inflammatory diseases. SCFAs have been linked to beneficial effects on colon health by promoting an anti-inflammatory environment, which can mitigate conditions such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).
2. Immune Optimisation:
Chlorella vulgaris has demonstrated significant potential in immune regulation, particularly through its positive influence on T cells (Tregs). These cells are a subset of T cells that play a pivotal role in maintaining immune tolerance and preventing autoimmune and inflammatory responses.
Increase in Treg Population: Research in animal models, such as mice, has shown that supplementation with Chlorella vulgaris can lead to an increase in the population of Tregs. These cells are crucial for modulating the immune system, maintaining tolerance to self-antigens, and preventing pathological immune responses against the body’s own cells and tissues.
Modulation of Immune Responses: Tregs help control the immune response by suppressing overactive immune cells, preventing excessive inflammation which can damage tissues. Chlorella’s ability to enhance Treg numbers suggests that it helps create a more regulated and less inflammatory immune environment in the gut.
The increased presence of Tregs can be particularly beneficial in managing diseases characterised by inflammation of the gut, such as Crohn's disease and ulcerative colitis—collectively known as inflammatory bowel diseases (IBD)
3. Detoxification Properties:
Chlorella is well known for its detoxification properties, particularly its ability to bind with heavy metals and other environmental toxins. This capability can significantly contribute to maintaining a healthier gut environment and improve overall health.
Binding with Toxins: Chlorella has a high concentration of chlorophyll (the highest of any plant), which are known to bind with heavy metals like lead, mercury, and cadmium, as well as other toxins present in the gut. By binding to these harmful substances, chlorella prevents their absorption in the digestive system and facilitates their excretion from the body.
Enhancement of Toxin Elimination: The fibrous cell wall of chlorella is thought to absorb toxins and promote their removal through faecal excretion. This detoxification process is vital as it helps reduce the toxin load on the body, which can otherwise lead to various health issues, including oxidative stress and inflammation that can damage gut tissues. Chlorella's detoxifying effects also support liver health, a crucial organ for detoxification processes. Healthier liver function can enhance overall digestion and metabolism.
4. Rich in Fibre:
Chlorella is a valuable source of dietary fibre, which is fundamental for maintaining optimal gut health. Its fibre content plays several key roles in digestive health, enhancing both mechanical and biochemical processes within the digestive system.
Promotion of Bowel Regularity: Dietary fibre in chlorella helps to bulk up stool and promote regular bowel movements, which is essential for preventing constipation. This regularity is crucial for avoiding conditions such as haemorrhoids and diverticular disease, which are often exacerbated by irregular bowel habits.
Stimulation of Healthy Gut Bacteria Growth: The fibre in chlorella acts as a prebiotic, providing a food source for beneficial gut bacteria. These microbes ferment the fibre into short-chain fatty acids (SCFAs), which are vital for maintaining gut barrier integrity and modulating the immune system.
5. Anti-inflammatory Effects:
Chlorella is rich in various anti-inflammatory compounds, including chlorophyll, omega-3 fatty acids, and a huge array of antioxidants. These substances offer significant benefits for the digestive system by mitigating inflammation and potentially alleviating symptoms of digestive disorders.
Antioxidant Activity: Chlorella is also a source of various antioxidants, which help combat oxidative stress—a condition that contributes to inflammation. These antioxidants neutralise free radicals, unstable molecules that can damage cells and tissue, thereby mitigating inflammation at a molecular level.
Support for Long-term Gut Health: Continuous use of chlorella as part of a balanced diet might help prevent the onset of inflammation-related digestive disorders, promoting long-term health and preventing future gut-related health issues.
Chlorella Nutritional Table:
"The great thing about chlorella is that it's the highest concentration of chlorophyll in the world, chlorophyll has the same chemical composition as your hemoglobin so it's very powerful to build your blood, which builds your immune system, which builds your gut which builds everything"
Experts Quotes and Opinions About Chlorella and Gut Health:
The following are a set of quotes from doctors and healthcare specialists that have spoken about about chlorella and it's gut health benefits.
- "It may help to balance the pH in your gut, which in turn, helps probiotics thrive." Dr Wolf (LuckyVitamin).
- "Chlorella has a really positive effect on the gut microbiome... it's kind of like a superfood for them too." - Dr. Patricia Mills.
- "Chlorella increases what's called phase 2 detoxification within the liver. Phase 2 is where you take fat-soluble toxins, which most toxins are stored in the fat, and break them down into a water-soluble form so the body can excrete them." Thomas Delauer.
