The most common species used as a dietary supplement are <em>Arthrospira platensis<\/em> and <em>Arthrospira maxima<\/em>. It has gotten its name from its spiral-shaped structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It has been a food source in cultures in Africa and Central America for centuries due to its exceptionally high nutritional content. It consists of up to 70% protein (by dry weight), contains all essential amino acids, and is rich in B vitamins, iron, beta-carotene, and gamma-linolenic acid (GLA).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most studied active substance in Spirulina is phycocyanin. It is a pigment-protein complex that gives the algae its characteristic blue-green color and at the same time is responsible for many of its health properties [2].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">History<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Spirulina has been used as a food source in at least two historical epicenters. The Aztecs in Mexico harvested it from Lake Texcoco and shaped it into cakes called &#8220;tecuitlatl.&#8221; At the same time, the Kanembu people by Lake Chad in central Africa traditionally harvested and dried the algae for use in cooking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the Western world, Spirulina first became widely known in the 1960s. Since then, it has been cultivated commercially in large, controlled ponds around the world and is recognized as a &#8220;superfood&#8221; due to its dense nutritional profile.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Spirulina_vs_Chlorella\"><\/span>Spirulina vs. Chlorella<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina5-150x150.jpg\" alt=\"Spirulina symboliseret ved nogle bakkede formationer med gr\u00f8n algev\u00e6kst.\" class=\"wp-image-36463\" style=\"width:auto;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina5-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina5-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina5-100x100.jpg 100w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Although Spirulina and Chlorella are both nutrient-rich algae, they are fundamentally different.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Type:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Spirulina is technically a cyanobacterium (a blue-green alga) and is spiral-shaped. Chlorella is a single-celled green alga (a eukaryote, like plants) and is spherical.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cell wall:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Spirulina does not have a hard cell wall and is therefore easily digestible in its natural form. Chlorella has a very hard cell wall of cellulose that must be broken down (a process where the cell wall is broken down) for humans to absorb the nutrients.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Nutritional profile:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Spirulina is generally richer in protein and the unique blue pigment <em>phycocyanin<\/em>, which has strong antioxidant properties.

Research has shown that it has several interesting mechanisms of action. It functions as a powerful antioxidant that can neutralize reactive oxygen species (free radicals) and protect cell membranes and DNA from oxidative damage [5].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Anti-inflammatory potential<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Spirulina, and specifically phycocyanin, has been shown to be able to inhibit central inflammatory processes. It can block the enzyme COX-2 (cyclooxygenase-2), which is involved in the production of inflammatory prostaglandins &#8211; the same signaling molecules that anti-inflammatory medication (NSAIDs) often target. It also appears to be able to downregulate the production of pro-inflammatory cytokines, such as TNF-alpha and Interleukin-6 (IL-6) [1].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Immunomodulation<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Spirulina has an immunomodulatory effect, meaning it can affect the activity of the immune system. Studies suggest that it can stimulate the production and activity of immune cells such as NK cells (Natural Killer cells) and T helper cells. These cells are crucial for the body&#8217;s &#8220;immune surveillance&#8221; &#8211; the ability to recognize and eliminate abnormal cells, including cancer cells [5].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Potential_in_cancer\"><\/span>Potential in cancer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-150x150.jpg\" alt=\"Spirulina symboliseret ved mikroskopifoto af spirulina-alger.\" class=\"wp-image-23231\" style=\"width:auto;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-100x100.jpg 100w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-600x600.jpg 600w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12-768x768.jpg 768w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina12.jpg 1024w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Most of the specific research on Spirulina and cancer comes from in vitro (test tubes\/petri dishes) and in vivo (in living organisms, typically mice) studies. The results from these point to several interesting potentials.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Induction of apoptosis<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Apoptosis is the body&#8217;s natural process for programmed cell death, a mechanism that cancer cells often evade. Several laboratory studies have shown that phycocyanin can initiate apoptosis signaling pathways in various cancer cell lines, including breast cancer, liver cancer, and colon cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The substance appears to be able to activate the enzymes (caspases) that are responsible for initiating the controlled breakdown of the cell from within [2].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Inhibition of cell growth<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to promoting cell death, phycocyanin appears to be able to slow down cell division (proliferation). It can disrupt the cancer cell&#8217;s cycle and prevent it from copying itself unchecked.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Anti-angiogenesis<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A tumor needs a constant blood supply to grow. The process by which the tumor forms new blood vessels is called angiogenesis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Preclinical studies have indicated that extracts of spirulina can inhibit the growth factors, such as VEGF (Vascular Endothelial Growth Factor), that the tumor emits to attract new blood vessels.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Protection of healthy cells<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most relevant potentials is Spirulina&#8217;s ability to protect healthy cells from the toxicity that comes with chemotherapy and radiation therapy. Due to its strong antioxidant capacity, Spirulina can help neutralize the free radicals that these treatments generate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Studies on mice have shown that spirulina can reduce damage to kidneys, liver, and bone marrow caused by chemotherapeutic agents such as cisplatin, without appearing to reduce the cancer-killing effect of the chemotherapy itself [1].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Benefits_of_Spirulina\"><\/span>Benefits of Spirulina<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina4-150x150.jpg\" alt=\"Spirulina symboliseret ved vand og klipper og gr\u00f8nne synlige alger i vandet.\" class=\"wp-image-23226\" style=\"width:auto;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina4-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina4-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina4-100x100.jpg 100w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the specific mechanisms of action, Spirulina has nutritional benefits that can be relevant during a cancer course.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">High nutritional content<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Cancer and cancer treatment often lead to unintended weight loss, loss of muscle mass, and malnutrition (cachexia). Spirulina is one of the most concentrated protein sources found (up to 70% dry weight).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The protein is complete (contains all essential amino acids) and easily digestible, as the algae lacks the hard cell wall of cellulose that chlorella has.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Support for anemia and fatigue<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Iron deficiency and anemia are common during cancer treatment and contribute to pronounced fatigue. Spirulina is a rich source of bioavailable iron and B vitamins, which are necessary for the formation of red blood cells.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Prebiotic properties<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A healthy gut flora is crucial for the immune system and general health. Spirulina has been shown to function as a prebiotic, feeding beneficial gut bacteria such as Lactobacillus and Bifidobacterium, and can contribute to maintaining healthy gut function [3].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Disadvantages_and_limitations\"><\/span>Disadvantages and limitations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina8-150x150.jpg\" alt=\"Spirulina symboliseret ved lysegr\u00f8nne alger\" class=\"wp-image-23222\" style=\"width:auto;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina8-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina8-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina8-100x100.jpg 100w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The biggest concern with spirulina is not the algae itself, but the risk of contamination if it is not cultivated correctly.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Contamination with heavy metals<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Spirulina is extremely effective at absorbing minerals from the water in which it grows. If it is grown in contaminated water, it will also absorb heavy metals such as mercury, lead, cadmium, and arsenic.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Risk of microcystins<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">If wild blue-green algae (which are not Arthrospira) are accidentally harvested along with spirulina, there is a risk of contamination with microcystins. These are potent liver toxins that can cause serious damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, it is crucial to use products exclusively from recognized manufacturers that can present certificates and third-party tests that guarantee that the product is pure and free from both heavy metals and microcystins [4].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Interactions and autoimmune conditions<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Due to Spirulina&#8217;s immune-stimulating effect, there is a theoretical concern that it may worsen symptoms in autoimmune diseases (such as rheumatoid arthritis or multiple sclerosis). In addition, spirulina contains vitamin K, which theoretically can reduce the effect of blood-thinning medication (warfarin).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Clinical_trials\"><\/span>Clinical trials<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina11-150x150.jpg\" alt=\"Spirulina symboliseret ved planche af gr\u00f8nne spirulinaalger der danner en rundkreds.

The human studies that do exist often focus on spirulina&#8217;s ability to improve blood lipids (cholesterol), blood sugar control, or its general antioxidant status [3, 5].<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, human studies have been conducted regarding precancerous conditions. A study on people with oral leukoplakia (white patches in the mouth that can develop into cancer) showed that intake of spirulina led to a significant regression of the lesions in some of the participants.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Safety\"><\/span>Safety<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-150x150.jpg\" alt=\"Spirulina symboliseret ved gr\u00f8nt spirulina pulver i en petrisk\u00e5l og lidt pulver p\u00e5 bordet foran dette.\" class=\"wp-image-23220\" style=\"width:auto;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-100x100.jpg 100w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-600x600.jpg 600w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10-768x768.jpg 768w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/10\/Spirulina10.jpg 853w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">When spirulina is grown under controlled conditions and is certified free from contamination, it is considered very safe to consume, even in relatively high doses. It has GRAS (Generally Recognized As Safe) status by the US health authorities (FDA) [4].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Common side effects<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Mild side effects can occur, especially at the start. These typically include mild digestive discomfort, nausea, gas in the stomach, or headache.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some experience a slight feverish feeling, which may be due to the intense metabolism of the high protein content.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Importance of source<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Repetition is necessary here: Safety depends entirely on the source. One should avoid cheap products without clear origin or test documentation.
