What characteristics should you look for in good chlorella supplements?
Chlorella pyrenoidosa or vulgaris: The most commonly used species of chlorella—they contain high amounts of chlorophyll, protein, and vitamins, and support the body’s detoxification process.
Vitamin B12 (in its active form—e.g., methylcobalamin): Supports the nervous system and red blood cell production; particularly important for vegans, who are often deficient in it.
Spirulina: Often combined with chlorella for a synergistic effect—it provides additional protein and phycocyanin and has anti-inflammatory properties.
Chlorophyll: Naturally present in chlorella, but sometimes additionally enriched—it aids in blood purification and supports cell regeneration.
Prebiotics (e.g., inulin): Support gut flora and improve the absorption of nutrients from chlorella.
Vitamin C: May aid in the absorption of iron contained in chlorella and acts as a powerful antioxidant.
Selenium and zinc: Trace minerals that support immunity and the activity of antioxidant enzymes; often combined with chlorella for a more comprehensive health benefit.

Nutridome’s Chlorella pyrenoidosa is a high-quality dietary supplement that combines the natural detoxifying properties of algae with modern technology that enhances nutrient absorption. Our testers were delighted that a single daily serving contains as much as 1,500 mg of pure chlorella, which effectively supports the body’s detoxification from toxins and heavy metals, and also has a beneficial effect on liver, intestinal, and immune system function. Our testers appreciated that Chlorella Nutridome contains no unnecessary additives—the supplement is free of sugar, lactose, salt, soy, artificial colors, iodine, and heavy metals. An additional advantage is the Steam technology, which gently breaks down the cell walls of the algae, significantly improving the absorption of the vitamins, minerals, and chlorophyll contained in chlorella. As a result, the supplement not only supports detoxification but also improves digestion, gut microbiota, and energy levels. The product received the highest ratings from our testers due to its composition, the purity of its raw materials, the absence of controversial additives, and its effective results, which are noticeable after just a few weeks of use. For those seeking natural, fast, and effective support for their bodies, Chlorella Nutridome is definitely the best choice.
Kenay Organic Chlorella is a supplement that caught our testers’ attention thanks to its high content of natural vitamins and minerals derived from Chlorella vulgaris algae grown under controlled, organic conditions. The testers noted that a daily serving contains, among other things, beta-carotene (vitamin A), which supports vision and skin health; a high dose of vitamin B12 (712% of the Recommended Daily Intake); which is essential for the nervous system, and vitamin K, which supports blood clotting. The presence of lutein and zeaxanthin helps protect the eyes, and the CGF (Chlorella Growth Factor) complex supports cellular regeneration. Our testers praised the product for being free of pesticides, GMOs, and toxins. The testers noted that a significant drawback is the lack of technology to enhance nutrient absorption, such as Steam, which is used in other products. Additionally, the fact that it is sourced from India may raise concerns among those who prefer European supplements.
Aliness Chlorella Vulgaris Powder is a powdered dietary supplement that provides as much as 6 g of common chlorella in the recommended daily serving. It is particularly rich in plant protein, fiber, chlorophyll, and essential micronutrients—iron, zinc, vitamin A, and a high dose of vitamin B12. As a result, it supports the immune system, detoxification, and energy production. Our testers noted that the powdered form makes it easy to add the supplement to smoothies, yogurt, or soups, but for some people, the taste and strong smell of chlorella may be hard to tolerate. Another drawback may be the lack of information regarding technology that enhances bioavailability, as well as the absence of an organic certification, which is increasingly becoming the standard for this type of product. Despite this, the product is valued for its pure composition, high chlorophyll content, and lack of unnecessary additives.
Source Naturals’ Yaeyama Chlorella is a premium-quality supplement sourced from the pristine waters surrounding the Japanese island of Ishigaki. It contains 2,000 mg of chlorella per daily serving, which is a source of natural vitamin B12, iron, and vitamin A—key nutrients for the immune, hematopoietic, and nervous systems. The high chlorophyll content promotes detoxification, and the presence of complete plant protein supports those on vegetarian and vegan diets. Our testers noted that the supplement has a very clean ingredient profile and comes from a reputable source; however, its exorbitantly high price clearly sets it apart from other products, which may be a barrier for those seeking daily support on a reasonable budget. Another drawback may be the large number of tablets to take daily (as many as 10!). Nevertheless, the purity of the microalgae and the absence of GMOs make this a great option for the most discerning users, provided they don’t mind the distinct taste and smell of the supplement, which our testers didn’t like.
Chlorella Detox by Purella Superfoods is a dietary supplement made from 100% powdered Chlorella vulgaris, sourced from controlled farms in South Korea. Chlorella contains natural chlorophyll, which supports the body’s detoxification processes, as well as vitamin A, which promotes healthy skin, mucous membranes, and vision. The algae also supports digestion, liver function, and the immune system. Our testers noted that although the ingredients are pure, the product did not work for everyone. Some testers experienced nausea or stomachaches, and a few had to stop taking the supplement entirely due to severe allergic reactions (rash, shortness of breath). Criticism was also directed at the low vitamin and mineral content compared to competitors, as well as the large number of tablets to be taken daily (as many as 12). Despite the low price, the effects were not noticeable enough for many people.
