Abstract

Spirulina, now named Arthrospira, is a microscopic and filamentous cyanobacterium that has a long history of use as a safe food lacking toxicity. It is commercially produced in large outdoor ponds under controlled conditions. The aim of this review article is to summarize available recent information concerning human clinical potential and applications of Spirulina, as well as clinical data related to the safety and side effects of Spirulina. Potential health benefits of Spirulina are mainly due to its chemical composition, which includes proteins (the highest protein content of any natural food, 55%-70%), carbohydrates, essential amino acids, minerals (especially iron), essential fatty acids, vitamins, and pigments. In this respect, three major bioactive components of Spirulina, the protein phycocyanin (a biliprotein pigment), sulfated polysaccharides and gamma linolenic acid seem to play significant role in imparting improved human body functions. Furthermore, new experimental evidence supports the immunomodulation and antiviral effects of Spirulina supplementation. According to the Dietary Supplements Information Expert Committee of United States Pharmacopeial Convention the available clinical evidence does not indicate a serious risk to health or other public health concerns for Spirulina. However, a few cases of severe side-effects have been reported.

  • Phycobiliprotein C-phycocyanin and allophycocyanin in a ratio of about 10:1 are responsible for the majority of spirulina's beneficial effects on human health.

    “The plant proteins known as phycobiliprotein, which are C-phycocyanin and allophycocyanin in a ratio of around 10:1, are responsible for the majority of spirulina’s beneficial effects on human health [32,45].”

    From Trends and Technological Advancements in the Possible Food Applications of Spirulina and Their Health Benefits: A Review. (2022) · cites this paper as [45]

    The Chemical Composition section identifies C-phycocyanin and allophycocyanin at approximately a 10:1 ratio as proteins with significant health effects. It does not say they account for the majority of Spirulina’s health benefits; the same section also names polysaccharides, gamma-linolenic acid and sulfolipids as promising active constituents.

  • The daily needs of vitamins B1, B2, B3, and B12 are met by consuming 20 g of spirulina, making it a complete source of these vitamins.

    “Because the daily needs of vitamins B1, B2, B3, and B12 are met by consuming 20 g of spirulina, it is considered a complete source of these vitamins [45].”

    From Trends and Technological Advancements in the Possible Food Applications of Spirulina and Their Health Benefits: A Review. (2022) · cites this paper as [45]

    The Chemical Composition section says 20 g of Spirulina fulfills significant requirements for vitamins B1, B2, and B3. It does not include B12 in that statement; the Safety Aspects section says Spirulina contains B12 analogues that do not fulfill vitamin B12’s functional roles in humans. The claim that 20 g meets the daily need for all four vitamins is therefore not supported. (LLM, conf=0.92)

  • C-phycocyanin accounts for around 20% of the dry weight of spirulina and is sold commercially as an antioxidant, anti-inflammatory agent, and natural colorant.

    “The primary pigment is called C-phycocyanin, and it accounts for around 20% of the dry weight of the substance. It is also sold in the commercial world as an antioxidant and an anti-inflammatory agent, in addition to its usage as a natural colorant.”

    From Trends and Technological Advancements in the Possible Food Applications of Spirulina and Their Health Benefits: A Review. (2022) · cites this paper as [45]

    The Chemical Composition section identifies C-phycocyanin as a Spirulina pigment and says phycocyanins make up about 15–25% of its dry biomass, consistent with around 20%. The Introduction mentions commercial natural-color products made from Spirulina or its extracts, but the paper does not say C-phycocyanin itself is sold commercially as an antioxidant or anti-inflammatory agent. Page numbers are not available in our copy. (LLM, conf=0.86)

  • The spirulina algae product possesses many pharmacological activities, including anticancer, antiviral, antimicrobial, anti-heavy metal, immunomodulatory, and antioxidant, due to its high content of protein and PUFAs, particularly γ-linolenic acid.

    “It was reported by Hosseini et al. [33] that the spirulina algae product possesses many pharmacological activities, such as anticancer, antiviral, antimicrobial, anti–heavy metal, immunomodulatory, and antioxidant due to its high content of protein and PUFAs, particularly the high content of γ-linolenic acid.”

  • The clinical data that are now available do not show that ingesting spirulina poses a threat to one's health, as stated by the US Food Supplements Convention.

    “The clinical data that are now available do not show that ingesting spirulina poses a threat to one’s health, as stated by the US Food Supplements Convention [45].”

    From Trends and Technological Advancements in the Possible Food Applications of Spirulina and Their Health Benefits: A Review. (2022) · cites this paper as [45]

    The Side effects section reports that the Dietary Supplements Information Expert Committee found no evidence of a serious health risk or other public-health concern from Spirulina. The claim broadens this to no threat to health, although the same section reports side effects, including a few severe cases. It also misnames the body, which the paper identifies as part of the United States Pharmacopeial Convention. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
