What is Chlorella?
Chlorella is a single-celled algae that contains a wide range of concentrated vitamins and minerals, which are considered essential to the human body. (1)
The algae plant is dried and supplemented into a variety of supplements.
Many of these products will vary significantly depending on how they were cultivated, harvested, and processed for supplements.
Chlorella is commonly grown in Japan and Taiwan however it is commonly available in the U.S. and manufactured in CGMP certified facilities across the country.
Health Benefits of Chlorella
There are many health benefits due to its antioxidant, anti-inflammatory, and antimicrobial activities and dense nutrient content, including carotenoids, chlorophyll, minerals, vitamins, and long-chain polyunsaturated fatty acids.
In addition to the positive properties Chlorella produces a molecule known as “lutein”which has been proved to prevent macular degeneration.
Chlorella extract has shown promising effects of lowering cholesterol, lower blood pressure, speed up wound healing, and improvements of the immune system.
Many studies suggest that chlorella may even have the capability to relieve symptoms and improve the lifestyle of individuals who suffer from fibromyalgia, hypertension and ulcerative colitis (UC).
Controlled studies conclude that daily consumption of Chlorella may improve serum lipid profile by boosting the body’s carotenoid concentration for individuals who suffer from high blood pressure. (1)
Other compounds found in Chlorella may also help lower cholesterol:
Antioxidants: May help prevent the oxidation of LDL cholesterol and help fight against free radicals
Niacin: This B vitamin may raise your HDL, “good”, cholesterol and lower LDL “bad” cholesterol levels by by 10% – 25%. (2)
Fiber: Insoluble fibers have been shown to produce SCFAs which work as a cholesterol-lowering agent. (3)
Research suggests that GABA-rich chlorella has been shown to significantly decrease high-normal blood pressure and borderline hypertension.
Chlorella’s nutrient content could potentially promote endurance, however many have claimed it improves energy levels, promotes liver health and aids in digestion.
Chlorella is rich in lutein and zeaxanthin.
These two carotenoids that help protect the eye and have been associated with lowering the risk of macular degeneration. (4)
Researchers have looked at the potential effects and impact of Chlorella on anxiety and depression separately, they observed that it had a positive effect on both aspects. (5)
Some research indicates chlorella may be beneficial for people who have UC but more research on the topic is needed. (6)
Studies have confirmed supplementation of Chlorella enhances the NK cell activity and produces interferon- γ and interleukin-12 which has shown to provide immune support. (7)
A 1995 clinical study that consisted of 23 patients with borderline hypertension patients were given 1.5g of chlorella daily for 6 months.
The subject questionnaire answered by the group indicated that there was a reduction of hypertension-related symptoms and overall improvements in the general condition. (8) (9)
A recent blind study of supplementation of Chlorella for three months found improvements in FMS (Fibromyalgia Syndrome) while the study subjects were taking the chlorella. (10) (11)
Animal studies have found that the carotenoids found in chlorella extract pronounced antitumor effects in both spontaneous and experimentally induced metastasis in mice. (12)
More human research needs to be conducted for sufficient evidence on cancer in human patients. (12) (13) (14)
In some instances, chlorella has been shown to onset and cause allergic reactions and adverse side effects depending on the user.
For this reason, it’s highly recommended to speak to your physician if you are pregnant or nursing.
Potential Side Effects of Chlorella
Chlorella has been thought to be safe if taken orally for a couple of months, however, users have reported having allergic reactions, which may have led to breathing problems in some people.

What to Look for in a Chlorella Supplement
There are several species of chlorella. Pyrenoidosa chlorella supplements are recommended because they’re the most studied and have been found to be more nutrient-dense. Pyrenoidosa has a higher concentration of essential vitamins and amino acids.
Look for a product that contains a sufficient dose, a good place to start is by choosing a product that is above 250mg per dose.
Consider a chlorella product that has a broken cell wall, as this will ensure that the body is able to absorb the beneficial compounds found within the chlorella.
Be sure to choose a product that is third-party tested to ensure there are no contaminants or toxins in the chlorella.
Choose a product that is sold domestically and one that is manufactured and processed in a cGMP certified facility.
Cracked wall Chlorella
Chlorella has hard cell walls and a high fiber content that our bodies are unable to digest as a whole food.
When the cell wall barrier is broken through a process known as “cell disruption“ the human body is able to absorb beneficial compounds that chlorella has to offer.
Overall, this increases the absorption of the Chlorella and more benefits may be hosted according to science.
Chlorella supplements that have undergone this process will come in powder, extracts, or capsules that have undergone the process.
During the manufacturing of chlorella, ingredients may be added to adulterate the process to be cost-effective. Look for chlorella products that are organic.
Avoid Contaminants/Any Harmful Additives
One should avoid any chlorella supplements that are not manufactured in a certified GMP facility.
The whole sourced chrolleralla plant may have been grown in contaminated bodies of water and even toxic in some cases so third-party testing is essential no matter the chlorella supplement.
Avoid any products that contain harmful ingredients and try to aim for organic to ensure that no pesticides or harmful additives were used in the process.
Differences Between Chlorella and Spirulina
Biologically speaking there are many differences between these two plants.
Chlorella is classified as algae and eukaryote which are complex plants with chromosomes and different cell structures.
While on the other hand, spirulina is classified as a prokaryote which is unlike other living cells due to a lack of a nucleus that is surrounded by a membrane.
Both of these plants are highly nutritious and contain a broad-spectrum of essential vitamins and minerals, however, chlorella is more abundant. (15)
How Much Chlorella You Should Take and When
Consumers have reported noticing benefits from 2-5 grams of chlorella daily.
Doctors and nutritionists have suggested that 3-5 grams or 10-12 tablets per day, however, the optimal dose remains unknown and will vary with each product.
The best time to take chlorella is in the morning before meals and with a glass of water for best results. (16)
