Chlorella Benefits: The Ultimate Guide

Known as the "world's first superfood," Chlorella is a freshwater green algae that is packed with nutrients and health benefits. This 2 billion-year-old superfood is known for its high nutritional content, which includes vitamins, minerals, antioxidants, and protein.

What is Chlorella?

Chlorella is a single-celled organism believed to have originated approximately 2 billion years ago, long before any plants or animals were on the Earth. It has one of the highest rates of photosynthesis ever tested, quadrupling in size every 20-24 hours.

Its remarkable ability to adapt to its environment has made it one of the most successful organisms in the history of the world, having survived at least five mass extinctions and thriving in diverse climates around the world.

By the 1940s and 50s, the world population was exploding, which increased research into alternative food source production. Chlorella was an early favorite of many researchers because of its full spectrum nutritional composition. As a result, it ended up becoming one of the most rigorously studied food sources in the world and could even be called the “world’s first superfood”.

Why Should You Take Chlorella?

It’s packed with nutrients! Below is a breakdown of exceptional chlorella benefits. And Chlorella powder (ex. capsules or loose powder in your morning smoothie) is one of the easiest ways to make it a part of your daily routine.

Chlorella is a nutrient-dense superfood that is a rich source of vitamins A, B1, B2, B3, B6, B12, C, E, and K, and minerals such as iron, magnesium, and zinc. It also contains high levels of protein, including all nine essential amino acids, making it a complete protein source.

Its vitamin A levels contribute to maintaining healthy vision, improving the clarity of the skin as well as supporting immune function. The B vitamin content is important for energy production, metabolism, and brain function. Chlorella’s nutritional factors are long believed to help slow down the aging process.

Chlorella is well known for its energizing and detoxifying properties. It also has the highest concentration of chlorophyll in the plant world and more nucleic acids than any other food. Chlorophyll is a fundamental pigment that gives plants their distinctive green colour by enabling them to absorb energy from light that is naturally produced by plants and algae. It is essential for photosynthesis - the process by which sunlight is converted into energy.

Another nutrient that chlorella is rich in is vitamin B12, which is one of the most difficult nutrients for vegetarians and vegans to obtain via the consumption of whole, plant-based foods. Long-term deficiency of vitamin B12 has serious health consequences.

Chlorella is also rich in antioxidants, which can help combat oxidative stress and harmful free radicals. Free radicals are unstable molecules that can cause cell damage and build up within the body. Oxidative Stress occurs when these same unstable molecules accumulate. Chlorella helps reduce oxidative stress while protecting us from damaging substances and toxins.

7 Health Benefits of Chlorella

1 . Immune system support

Chlorella has been scientifically proven to have immune-enhancing qualities and is packed full of antioxidants that shield the body against free radicals and improve overall well-being.

It has been shown to support the immune system by stimulating the production of white blood cells, which are responsible for fighting infections and diseases. It also has anti-inflammatory properties that can help reduce inflammation throughout the body, which in turn can help support a healthy immune response. Chronic inflammation can weaken the immune system and increase the risk of disease, so reducing inflammation is crucial for maintaining overall health.

This incredible algae can also enhance the gut microbiome, which is the collection of microorganisms that live in the digestive tract. A healthy gut microbiome is essential for a healthy immune system, and chlorella has been found to promote the growth of beneficial gut bacteria.

Chlorella has also been found to have antiviral and antibacterial properties, which can help the body fight off infections. In particular, chlorella has been found to be effective against certain strains of the influenza virus.

2. Weight management

A systematic review and meta-analysis published in the journal Clinical Nutrition in 2019 evaluated the effects of chlorella supplementation on body weight and body fat in overweight and obese adults.

The review included 15 randomized controlled trials with a total of 922 participants. The results showed that chlorella supplementation was associated with a significant reduction in body weight and body fat percentage compared to placebo.

Another randomized controlled trial published in the Journal of Medicinal Food in 2008 found that chlorella supplementation for 16 weeks significantly reduced body fat percentage and total cholesterol levels in healthy adults.

This impact on body weight may be due to its high nutrient content which can help to regulate appetite and promote satiety. Additionally, its rich source of dietary fiber can help to promote healthy digestion by moving food through the digestive system and preventing constipation.

When digestion is improved, the body can better absorb nutrients and eliminate waste, which can contribute to weight loss.

Another way chlorella can aid in weight management is through its anti-inflammatory properties. Chronic inflammation is linked to weight gain and obesity, as it can lead to insulin resistance and a higher risk of metabolic disorders. Chlorella has been shown to reduce inflammation in the body, which can help to regulate metabolism and improve weight management.

Chlorella's high protein content can be beneficial in weight management as protein is an essential macronutrientthat plays a key role in building and maintaining lean muscle mass.

By incorporating chlorella into a diet, you can increase your protein intake and support your weight loss goals by building lean muscle mass, which can in turn improve metabolism and support healthy weight management.

3. Diabetes Management

Chlorella can be beneficial for diabetes management due to its ability to improve insulin sensitivity, lower blood glucose levels, and reduce inflammation.

It contains several nutrients and bioactive compounds that can help regulate blood sugar levels, including chlorophyll, fibre, and antioxidants. These compounds work together to reduce the absorption of glucose in the digestive tract and improve insulin sensitivity.

Studies have shown that it can significantly lower fasting blood glucose levelsand improve glucose tolerance in individuals with type 2 diabetes. Additionally, chlorella has been found to reduce inflammation, which is often elevated in individuals with diabetes.

This ability to bring down inflammation can help reduce the risk of complications associated with diabetes, such as cardiovascular disease. Furthermore, chlorella has been found to have a positive effect on lipid metabolism, reducing cholesterol and triglyceride levels.

High levels of cholesterol and triglycerides are often seen in individuals with diabetes and can increase the risk of cardiovascular disease. By improving lipid metabolism, chlorella can help reduce this risk and improve overall health.

4. Anti-Cancer Properties

Studies have shown that chlorella can stimulate the production of natural killer cells, which are specialized immune cells that target cancer cells and viruses. By boosting the immune system's ability to fight off abnormal cells, chlorella may help prevent the formation and spread of cancerous tumors.

Another potential benefit of chlorella for cancer prevention is its high concentration of chlorophyll and carotenoids. These compounds can neutralize free radicals, which are unstable molecules that can damage DNA and other cellular components, leading to cancer development.

In addition, chlorella contains a unique compound called chlorella growth factor (CGF), which has been shown to have anti-tumor effectsin animal studies. While more research is needed to fully understand the mechanisms behind its anti-cancer effects, these initial findings are promising.

5. Cardiovascular health support

Chlorella has been shown to have a positive impact on cardiovascular health. Research suggests that it can lower blood pressure, reduce LDL cholesterol, and decrease the risk of developing atherosclerosis. One study found that participants who took chlorella supplements experienced a significant decrease in both systolic and diastolic blood pressure.

Chlorella has also been shown to decrease levels of total cholesterol, triglycerides, and LDL cholesterol while increasing levels of HDL cholesterol, which is often referred to as "good" cholesterol.

Atherosclerosis is a condition where plaque builds up in the arteries, and studies have shown that chlorella can help prevent this by reducing oxidative stress and inflammation.

In addition to its potential benefits for blood pressure and cholesterol levels, chlorella may also reduce the risk of developing heart disease.

One study found that taking chlorella supplements for 12 weeks improved endothelial function, which is an important factor in the development of cardiovascular disease.

Endothelial dysfunction can lead to the development of atherosclerosis and other cardiovascular issues. Another study showed that chlorella can prevent the development of hypertension, a major risk factor for heart disease.

While more research is needed to fully understand the mechanisms behind these effects, chlorella shows promise as a natural way to support cardiovascular health.

6. Anti-inflammatory properties

Chlorella has been found to have anti-inflammatory properties, which can benefit overall health. Inflammation is the body's natural response to injury, but chronic inflammation can lead to various health problems, including heart disease, diabetes, and cancer.

Chlorella has been shown to suppress the production of inflammatory cytokines, which are linked to chronic inflammation. By reducing inflammation, it may help prevent or manage these health issues.

Chlorella's anti-inflammatory properties can also benefit those with arthritis, a condition characterized by inflammation of the joints. Studies have shown that chlorella can reduce pain and inflammation associated with arthritis, possibly due to its ability to inhibit the production of inflammatory cytokines.

7. Detoxification

Chlorella has been scientifically proven to remove heavy metals like lead and mercury from the body by binding them with the body’s waste, helping it be expelled through digestion.

Chlorella has the ability to bind with heavy metals in the body because it is a “chelator”. Chelation is the process of removing toxic heavy metals from the body, which can accumulate from exposure to environmental toxins or from certain medical treatments. Chlorella appears to possess a high affinity for heavy metals which allows it to bind them onto cells within the body and ultimately eliminate them completely.

Chlorella contains a unique combination of phytonutrients, including chlorophyll and carotenoids, that enables it to bind with heavy metals and other toxins, facilitating their elimination from the body.

Research has shown that chlorella can be effective in removing heavy metals such as lead and mercury from the body. Overall, chlorella's chelation properties make it a valuable tool for supporting detoxification and promoting overall health and wellness.

Chelation has been demonstrated to have cardiovascular benefits and reduce the risk of developing kidney disease. It may also have neurological benefits, such as improving cognition in Alzheimer's patients or those with other forms of dementia.

A study published in the Journal of Agricultural and Food Chemistry demonstrated that Chlorella could bind to and remove lead from rats' digestive tracts. A second study, published in Environmental Science and Health, demonstrated how Chlorella reduced mercury levels in mice exposed to high concentrations of the metal.


Chlorella is a nutrient-dense superfood that can offer several health benefits for you. It is one of the most successful organisms in the history of the world. While more research is needed to fully understand how chlorella detoxifies the body, studies have shown it to be a safe and natural remedy for immune system support, weight management, diabetes control, chelation and detoxification. Adding Chlorella to your diet could be a major step forward in your overall health and wellbeing.
