The Nature of Blue-Green Algae
The group of organisms known as cyanobacteria is diverse and has a vast morphological variety and ecological niches. They are common in both aquatic and terrestrial habitats and have had a big impact on how the biosphere of Earth has developed. The Great Oxygenation Event, a large rise in atmospheric oxygen levels around 2.4 billion years ago, was caused by cyanobacteria. The development of aerobic life forms, including humans, was made possible by this occurrence.
The two main genera of cyanobacteria that are utilized as dietary supplements are Spirulina and Aphanizomenon. Aphanizomenon is a planktonic, free-floating organism, whereas spirulina is a filamentous cyanobacterium. To ensure ideal growth and purity, these species are either taken from natural water bodies or grown in controlled conditions.

Additionally, they offer a healthy ratio of omega-3 to omega-6 fatty acids. Vitamins A, B1, B2, B3, B6, and E, as well as minerals including iron, calcium, magnesium, and zinc, are particularly abundant in spirulina.
b. Inflammatory and Antioxidant Properties
The phytochemicals found in blue-green algae, including phycocyanin, chlorophyll, and carotenoids, have anti-inflammatory and antioxidant properties. These substances neutralize free radicals and lessen oxidative stress, preventing cellular damage and chronic inflammatory illnesses.
c. Effects on Immunomodulation
According to studies, blue-green algae can influence immune response by increasing the activity of natural killer cells and cytokine synthesis. These outcomes could support healthy immune function and infection prevention.
d. Effects on lowering lipids and preventing diabetes
It has been demonstrated that blue-green algae increase high-density lipoprotein (HDL) cholesterol while decreasing total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride levels. They may enhance insulin sensitivity and glucose homeostasis, which makes them a possible supplementary therapy for treating dyslipidemia and type 2 diabetes.
e. Effects of neuroprotection
Compounds produced from cyanobacteria, like phycocyanobilin, have been shown to have neuroprotective benefits by lowering brain inflammation, oxidative stress, and cytotoxicity. Potential uses for these characteristics include the prevention or treatment of neurodegenerative diseases like Parkinson’s and Alzheimer’s.
Chemistry of Blue-Green Algae
A wide variety of bioactive substances found in blue-green algae contribute to their ability to promote health. The following groups can be used to classify these compounds broadly:
a. Colourants
Many pigments found in cyanobacteria have antioxidant properties and perform important roles in photosynthesis. These include phycobiliproteins like phycocyanin and phycoerythrin, which contribute to the blue color, and chlorophyll, which gives the green color.
b. Amino Acids and Proteins
Spirulina has a high protein content that can range from 60 to 70 percent of its dry weight. As mentioned, blue-green algae contain all nine essential proteins.
c. Fatty Acids
Omega-3 and omega-6 essential fatty acids are abundant in cyanobacteria. Gamma-linolenic acid (GLA), alpha-linolenic acid (ALA), and linoleic acid (LA) are the three fatty acids that are most prevalent in blue-green algae.
d. Polysaccharides
Exopolysaccharides and sulfated polysaccharides are two types of polysaccharides that are produced by blue-green algae and have anti-inflammatory, antioxidant, and immunomodulatory properties.
e. Minerals and vitamins,
Vitamins A, B1, B2, B3, B6, E, and K, as well as minerals like calcium, iron, magnesium, and zinc, can all be found in abundance in blue-green algae.
Physiological Mechanisms of Action of Blue Green Algae
Through a variety of physiological pathways, the numerous bioactive chemicals in blue-green algae contribute to their health advantages:
a. Mechanisms of antioxidants
Phytocyanin, chlorophyll, and carotenoids in the algae help lower oxidative stress and neutralize reactive oxygen species (ROS). These antioxidants shield DNA, proteins, and lipids within cells from the harm caused by free radicals.
b. Mechanisms that combat inflammation
The synthesis of pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF-a) and interleukin-6 (IL-6) is inhibited by blue-green algae, while the production of anti-inflammatory cytokines like interleukin-10 (IL-10) is encouraged.
c. Mechanisms of Immunomodulation
Blue-green algae contain polysaccharides and other bioactive substances that can boost immune cell activity, including the growth and activation of macrophages, T-cells, and natural killer cells, as well as the creation of antibodies.
d. Anti-diabetic and Lipid-lowering Mechanisms
By lowering dietary cholesterol absorption and boosting the conversion of cholesterol to bile acids, blue-green algae can enhance lipid metabolism. They might also change the expression of genes associated with lipogenesis and enhance the expression of genes related to fatty acid oxidation. Additionally, blue-green algae can improve peripheral tissues’ sensitivity to insulin and uptake of glucose, leading to better glycemic control.
e. Mechanisms that Protect the Brain
Cyanobacteria-derived compounds have neuroprotective effects by lowering oxidative stress, preventing the production of pro-inflammatory cytokines, and regulating glutamate receptor activity.
Optimal Dosage of Blue-Green Algae
The ideal dosage of supplements containing blue-green algae may change based on a person’s needs, needs, age, gender, and health status. For the majority of individuals, a daily dosage of 1–3 gm is generally regarded as safe and effective. Higher quantities (up to 10 gm per day) have been used in some studies for particular health concerns, however, it is advisable to speak with a doctor before taking higher doses.
Side Effects of Blue-Green Algae
Supplements containing blue-green algae are often well tolerated and have few negative effects. However, particularly when beginning supplementation, some people may have gastrointestinal discomforts, such as bloating, gas, or diarrhea. Usually, these side effects go away with sustained use or dosage reduction.
Selecting high-quality blue-green algae supplements is crucial because those that are contaminated with dangerous bacteria or toxins, including microcystins, can have a negative impact on a person’s health.
