Blue-Green Algae intro:

Blue-green algae, of which spirulina is a well-known example, is a group of 1,500 species of microscopic aquatic plants. The two most common species used for human consumption are Spirulina maxima and Spirulina platensis. Spirulina is particularly rich in protein and also contains carotenoids, vitamins, minerals, and essential fatty acids.

Blue-Green Algae deficiency signs:

As it is not an essential nutrient, blue-green algae is not associated with a deficiency state. However, people who do not consume several servings of vegetables per day could benefit from the carotenoids and other nutrients in blue-green algae. Since it is a complete protein, it can be used in place of some of the protein in a healthy diet. However, very large amounts are required to provide significant quantities of these nutrients from blue-green algae.

Blue-Green Algae sources and dosage:

Blue-green algae grow in some lakes, particularly those rich in salts, in Central and South America, and Africa. They are also grown in outdoor tanks specifically to be harvested for nutritional supplements. Blue-green algae can be taken as a powder or as flakes, capsules, or tablets. The typical manufacturer’s recommended intake is 2,000–3,000 mg per day divided throughout the day. However, typical amounts shown to have helpful properties in animal studies would be equivalent to 34 grams per day or more, for a 150-pound human.

Blue-Green Algae is treatment for:

Weight loss and obesity

Blue-Green Algae side effects

Few side effects have been reported from the ingestion of blue-green algae. However, as blue-green algae can accumulate heavy metals from contaminated water, consuming blue-green algae could increase the body’s load of lead, mercury, and cadmium, though noncontaminated blue-green algae have been identified. Another popular species of blue-green algae, Aphanizomenon flos-aquae, has been found to produce toxins. A few reports also describe allergic reactions to blue-green algae. Animal studies have found spirulina to be safe during pregnancy. There is one case report of a man who developed liver damage while taking spirulina. As he was also talking three prescription medications, it is not clear whether the spirulina caused or contributed to the liver injury. At the time of writing, there were no well-known drug interactions with blue-green algae.
