About Blue-Green Algae Nutrition (And Some Mindblowing Facts!)

Blue-green algae, or cyanobacteria, is one of the photosynthetic prokaryotes that live in aquatic ecosystems. Some of the species of BGA include Aphanizomenon flos-aquae (AFA), Spirulina platensis (SP), Spirulina maxima (SM), Spirulina fusiformis (SF), and Nostoc commune var. (NO), have been consumed by humans for millennia.mIn fact, the earliest recorded human consumption of SP dates back to the 14th-century Aztec civilisation, and the earliest record of human use of NO is traced to 1600 years ago in China. 

BGA is a rich natural food which contains many important types of nutrients such as essential amino acids, γ-linolenic acid (GLA), fibres, B vitamins, calcium, phosphorous, iron, β-carotene pigments, xanthophylls, and chlorophyll along with other bioactive molecules. Studies have shown that BGA has antiviral, antitumor, antioxidant, anti-inflammatory, antiallergic, antidiabetic, and antibacterial properties and lipid-lowering effects. The potential inhibition of BGA towards hyperlipidemia, inflammation, and oxidative stress might protect individuals from the development of CVD and NAFLD.

How Does Blue-Green Algae Help Your Body? 11 Health Benefits of Blue-Green Algae

Here are the different health benefits of blue-green algae: 

1. A Boon For Your Heart Health 

Blue-green algae (BGA), particularly Spirulina and Nostoc species, have athero-protective (prevents plaque buildup in arteries) properties that benefit heart health. This protection is mainly due to phycocyanin (PC), a compound found abundantly in BGA, which reduces the causes of inflammation and oxidative stress in the blood vessels. PC can decrease the development of fatty lesions in arteries by reducing superoxide anion (O2-) production, an unstable molecule that damages cells and triggers inflammation. 

Superoxide dismutase, an antioxidant enzyme, breaks down this anion into harmless molecules. Also, PC in BGA inhibits nuclear factor-kappa B (NF-κB), a transcription factor that promotes inflammation by activating genes for cytokines like tumour necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), which are associated with cardiovascular disease (CVD).

By preventing NF-κB from entering the cell nucleus, PC reduces inflammation and promotes a stable endothelial layer (inner blood vessel layer), reducing the risk of arterial plaque and heart disease.

2. Lowers Cholesterol and Triglyceride Levels 

The lipid-lowering effects of BGA are primarily driven by the downregulation of 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGR), an enzyme crucial for cholesterol synthesis in the liver. 

In vitro studies in HepG2 liver cells show that lipid extracts from BGA inhibit sterol-regulatory element-binding proteins (SREBP-1 and SREBP-2), which are transcription factors that activate genes for cholesterol synthesis. This downregulation leads to lowered levels of low-density lipoprotein cholesterol (LDL-C), known as "bad cholesterol." In animal studies, BGA's fibre components further aid in lowering cholesterol by reducing its absorption in the intestine and increasing its excretion as neutral sterols. 

Clinical studies indicate that BGA supplementation, like 2g of Spirulina daily, significantly lowers plasma triglycerides, LDL-C, and the ratio of total cholesterol to high-density lipoprotein cholesterol (HDL-C, the "good cholesterol"). Thus, BGA's effect on cholesterol metabolism can help manage dyslipidemia (imbalanced blood lipid levels), a key risk factor for CVD.

3. Prevents Oxidative Stress 

Blue-green algae (BGA) are one of the best foods that are high in antioxidants, which protect the body from oxidative stress caused by reactive oxygen species (ROS). ROS, unstable molecules like hydroxyl and peroxyl radicals, are harmful because they quickly react with nearby molecules to stabilise, leading to cellular damage, particularly in lipids and DNA. This damage can result in chronic conditions such as atherosclerosis and non-alcoholic steatohepatitis (NASH). 

BGA helps by delivering antioxidants like phycocyanin (C-PC), a pigment that scavenges free radicals, reducing ROS levels. Animal studies show BGA’s ability to lower lipid peroxidation and protect cells, improving levels of vital antioxidant enzymes like glutathione (GSH) peroxidase. In humans, BGA supplementation has been shown to decrease markers of oxidative stress, like malondialdehyde (MDA), while enhancing antioxidant enzyme activities in the blood. 

Thus, BGA not only neutralises harmful free radicals but also strengthens the body's defences against oxidative damage, supporting overall cellular health.

4. Has Anti-Inflammatory Effects 

BGA, particularly Spirulina, exhibits potent anti-inflammatory effects that play a protective role against chronic inflammation-related conditions, including atherosclerosis and arthritis. The primary compounds responsible are gamma-linolenic acid (GLA) and phycocyanin (PC). GLA, a polyunsaturated fatty acid, is metabolised into anti-inflammatory eicosanoids (signalling molecules that reduce inflammation) through enzymatic action involving cyclooxygenase and lipoxygenase enzymes. 

In cellular studies, BGA extracts inhibit NF-κB, a crucial transcription factor for inflammatory genes. Specifically, BGA prevents NF-κB's translocation to the nucleus, stopping the production of inflammatory cytokines such as TNF-α and IL-1β (proteins that mediate inflammation).

Furthermore, phycocyanin has been shown to reduce oxidative stress by inhibiting myeloperoxidase (MPO) activity, an enzyme that increases inflammation and tissue damage in inflammatory conditions like colitis (colon inflammation). Thus, BGA’s anti-inflammatory compounds aid in reducing the inflammatory response and maintaining cellular health, which is essential for preventing chronic diseases.

To further reduce inflammation and oxidative stress in the body, consider ToneOp Care’s Turmeric, Ginger, and Garlic capsules. 

5. Protects Against NAFLD 

Blue-green algae may aid in managing Non-Alcoholic Fatty Liver Disease (NAFLD), a condition where excessive fat builds up in the liver, not due to alcohol. NAFLD can progress to liver inflammation, fibrosis, and even liver cancer if oxidative stress and inflammation persist. BGA, especially Spirulina (SP) and Nostoc (NO) can help reduce fat accumulation by inhibiting enzymes and pathways that promote lipid synthesis, such as SREBP-1, a protein involved in fat production. 

In animal studies, BGA was shown to reduce liver fat and inflammation markers (e.g., TNF-α, IL-6) by decreasing pro-inflammatory molecules and oxidative damage. Clinical studies have also noted improvements in liver enzyme levels and reduced liver fat in NAFLD patients who consumed BGA. BGA's antioxidant and anti-inflammatory properties reduce liver stress and may prevent NAFLD from worsening, suggesting it is a supportive therapy for liver health.

6. Manages Symptoms of Menopause

Spirulina also benefits women’s health. Blue-green algae (BGA) contain phytoestrogens (plant-derived compounds similar to estrogen) that may bind to estrogen receptors in the body, especially the estrogen receptor beta (ERβ). These compounds modulate hormonal fluctuations, alleviating menopause symptoms like hot flashes and mood swings. 

Likewise, BGA provides gamma-linolenic acid (GLA), which supports the production of anti-inflammatory prostaglandins (hormone-like lipids). The presence of antioxidants like phycocyanin also helps reduce oxidative stress, further easing symptoms linked to menopause-related hormonal changes.

7. Enhances Cognitive Health

The phycocyanin in BGA supports cognitive health by reducing oxidative damage in neurons (nerve cells) and promoting the release of brain-derived neurotrophic factor (BDNF), which aids neuron repair and growth. BGA's high content of phenolic compounds acts on neurotransmitter synthesis, while its antioxidants protect against lipid peroxidation in brain cell membranes. Plus, gamma-aminobutyric acid (GABA) in BGA can bind to GABA receptors in the brain, reducing stress and promoting mental clarity.

8. Manages Anaemia and Beta-Thalassemia

The iron-rich nature of BGA helps alleviate iron-deficiency anaemia by directly boosting haemoglobin (oxygen-carrying protein in red blood cells). Furthermore, BGA’s cobalamin (Vitamin B12) is essential for erythropoiesis (red blood cell production) in bone marrow. Beta-thalassemia patients, who struggle with haemoglobin production, may benefit from BGA’s high antioxidant content, which reduces free radical damage in erythrocytes (red blood cells) and helps maintain cellular stability through the action of enzymes like superoxide dismutase (SOD).

9. Potential Anti-Cancer Properties

Blue-green algae contain phycocyanin and chlorophyll, both of which exhibit anti-cancer properties by modulating cellular pathways. Phycocyanin inhibits the nuclear factor kappa B (NF-κB) pathway, reducing inflammation and slowing cancer cell proliferation. Meanwhile, chlorophyllin, a derivative of chlorophyll, may bind to mutagenic compounds and reduce DNA damage. Likewise, beta-carotene and selenium in BGA protect cells from oxidative stress, further preventing tumour formation and progression.

10. Good For Weight Management

BGA aids weight management by modulating lipid metabolism and reducing the enzyme lipase, which breaks down dietary fats. Phycocyanin also inhibits the peroxisome proliferator-activated receptor gamma (PPARγ), which plays a role in fat storage and adipocyte (fat cell) differentiation. Spirulina contains fibres that slow gastric emptying, promoting satiety and reducing calorie intake.

11. Improves Muscle Strength and Endurance

Rich in branched-chain amino acids (BCAAs), BGA supports muscle protein synthesis, which is essential for strength and endurance. BGA’s antioxidants, including superoxide dismutase (SOD) and glutathione peroxidase (GPx), combat exercise-induced oxidative stress in muscle cells. The gamma-linolenic acid (GLA) in BGA further modulates inflammation, aiding in faster muscle recovery, while iron and vitamin B12 promote oxygen transport to muscles, enhancing endurance.
