Organic blue-green algae is one of the most nutrient dense foods on the planet. Blue Green Algae has superfood status due to high concentrations of proteins, vitamins and nutrients.
How is Blue-Green Algae Cultivated?
Most blue-green algae products contain Aphanizomenon flos-aquae harvested from Upper Klamath Lake in southern Oregon. Harvesting is done during the summertime, June to November. The algae is filtered to preserve the most vibrant blooms and then further purified by centrifugation. The AFA is then chilled and sold frozen or dried at low temperatures and sold as a powder.
Blue-Green Algae and Stem Cells
In adults, stem cells have the function of repairing damaged cells. Unfortunately, as we age, stem cells have a reduced restorative ability and are more vulnerable to oxidative stress. This results in the body being less able to repair itself. Based on previous studies that showed blue-green algae can modulate immune function, the Department of Neurosurgery at USF investigated the effects of AFA on cultured human stem cells. Researchers noted that preliminary results suggested an ethanol extract of AFA may promote human stem cell proliferation.
Blue Green Algae Is Extremely High in Many Nutrients
Blue Green Algae is an organism that grows in both fresh and salt water. It is a type of cyanobacteria, which is a family of single-celled microbes. Just like plants, cyanobacteria can produce energy from sunlight via a process called photosynthesis. Blue Green Algae was consumed by the ancient Aztecs but became popular again when NASA proposed that it could be grown in space for use by astronauts. A standard daily dose of Blue Green Algae is 1–3 grams, but doses of up to 10 grams per day have been used effectively.
This tiny alga is packed with nutrients. A single tablespoon (7 grams) of dried Blue Green Algae powder contains:
Protein: 4 grams
Vitamin B1 (thiamine): 11% of the RDA
Vitamin B2 (riboflavin): 15% of the RDA
Vitamin B3 (niacin): 4% of the RDA
Copper: 21% of the RDA
Iron: 11% of the RDA
It also contains decent amounts of magnesium, potassium and manganese and small amounts of almost every other nutrient that you need. In addition, the same amount holds only 20 calories and 1.7 grams of digestible carbs. Gram for gram, Blue Green Algae may be the single most nutritious food on the planet. A tablespoon (7 grams) of Blue Green Algae provides a small amount of fat — around 1 gram — including both omega-6 and omega-3 fatty acids in an approximately 1.5–1.0 ratio. The quality of the protein in Blue Green Algae is considered excellent — comparable to eggs. It gives all the essential amino acids that you need.
Powerful Antioxidant and Anti-Inflammatory Properties
Oxidative damage can harm your DNA and cells. This damage can drive chronic inflammation, which contributes to many diseases. Blue Green Algae is a fantastic source of antioxidants, which can protect against oxidative damage. Its main active component is called phycocyanin. This antioxidant substance also gives Blue Green Algae its unique blue-green color. Phycocyanin can fight free radicals and inhibit production of inflammatory signaling molecules, providing impressive antioxidant and anti-inflammatory effects.
Can Lower “Bad” LDL and Triglyceride Levels
Heart disease is the world's leading cause of death. Many risk factors are linked to an increased risk of heart disease. As it turns out, Blue Green Algae positively impacts many of these factors. For example, it can lower total cholesterol, “bad” LDL cholesterol and triglycerides, while raising “good” HDL cholesterol. In a study in 25 people, 2 grams of Blue Green Algae per day significantly improved these markers. Another study in people with high cholesterol determined that 1 gram of Blue Green Algae per day lowered triglycerides by 16.3% and “bad” LDL by 10.1% (10). Several other studies have found favorable effects — though with higher doses of 4.5–8 grams per day.
Protects “Bad” LDL Cholesterol From Oxidation
Fatty structures in your body are susceptible to oxidative damage. This is known as lipid peroxidation, a key driver of many serious diseases. For example, one of the key steps in the development of heart disease is the oxidation of “bad” LDL cholesterol. Interestingly, the antioxidants in Blue Green Algae appear to be particularly effective at reducing lipid peroxidation in humans. In a study in 37 people, 8 grams of Blue Green Algae per day significantly reduced markers of oxidative damage. It also increased levels of antioxidant enzymes in the blood.
May Reduce Blood Pressure
High blood pressure is a main driver of many serious diseases, including heart attacks, strokes and chronic kidney disease. A dose of 4.5 grams of Blue Green Algae per day has been shown to reduce blood pressure in individuals with normal levels. This reduction is thought to be driven by an increased production of nitric oxide, a signaling molecule that helps your blood vessels relax and dilate.
Improves Symptoms of Allergic Rhinitis
Allergic rhinitis is characterized by inflammation in your nasal passageways. It is triggered by environmental allergens, such as pollen, animal hair or even wheat dust. Blue Green Algae is a popular alternative treatment for symptoms of allergic rhinitis. In one study in 127 people with allergic rhinitis, 2 grams per day dramatically reduced symptoms like nasal discharge, sneezing, nasal congestion and itching.
May Be Effective Against Anemia
There are many different forms of anemia. The most common one is characterized by a reduction in hemoglobin or red blood cells in your blood. Anemia is fairly common in older adults, leading to prolonged feelings of weakness and fatigue. In a study in 40 older people with a history of anemia, Blue Green Algae supplements increased the hemoglobin content of red blood cells and improved immune function.
May Improve Muscle Strength and Endurance
Exercise-induced oxidative damage is a major contributor to muscle fatigue. Certain plant foods have antioxidant properties that can help athletes and physically active individuals minimize this damage. Blue Green Algae appears beneficial, as some studies pointed to improved muscle strength and endurance. In two studies, Blue Green Algae enhanced endurance, significantly increasing the time it took for people to become fatigued.
May Aid Blood Sugar Control
Studies link Blue Green Algae to significantly lower blood sugar levels. In some cases, it has outperformed popular medicines. In a two-month study in 25 people, 2 grams of Blue Green Algae per day led to an impressive reduction in blood sugar levels. Blood sugar levels decreased from 9% to 8%, which is substantial. Studies estimate that a 1% reduction in this marker can lower the risk of diabetes-related death by 21%.
