Abstract

1) Background: Spirulina (Arthrospira) maxima has shown beneficial effects such anti-dyslipidemic, antiviral, antioxidant and antihypertensive. However, there are few and limited clinical studies. 2) Methods: a prospective, randomized, parallel pilot study of 4.5 g administration of Spirulina maxima or placebo for 12 weeks in 16 patients with systemic arterial hypertension undergoing treatment with ACE inhibitors was performed to assess the effects on endothelial damage and oxidative stress indicators. The blood levels of sICAM-1, sVCAM-1, endothelin-1, and sE-selectin were quantified; the activities of catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase and concentrations of reduced glutathione, oxidized glutathione, and thiobarbituric acid reactive susbtances, were also quantified before and after the treatment period. 3) Results: There were statistically significant (p < 0.05) decreases in systolic blood pressure, sVCAM-1, sE-selectin and endothelin-1 levels, and increases in glutathione peroxidase activity and oxidized glutathione levels. 4) Conclusion: The effects found in the present study agree with antihypertensive and antioxidant effects previously reported for Spirulina maxima. However, this is the first report about the effects on indicators of endothelial damage. More research in this field is necessary to gain an insight into the effects of Spirulina on these indicators.

  • Randomized and placebo-controlled trials have demonstrated that supplementation with algal products such as Limnospira and Chlorella leads to significant reductions in systolic and diastolic blood pressure in individuals with mild to moderate hypertension.

    “Randomized and placebo-controlled trials have demonstrated that supplementation with algal products such as Limnospira (Spirulina) and Chlorella leads to significant reductions in systolic and diastolic blood pressure in individuals with mild to moderate hypertension [74–76].”

    From Navigating the potential of algal peptides: health effects, market applications, and scientific challenges (2026) · cites this paper as [75]

    The Results (§2.2) report a statistically significant reduction in systolic blood pressure at the final visit in the Spirulina group compared with placebo. They explicitly state that diastolic blood pressure did not change significantly, so this paper does not support the claim that Spirulina significantly reduced both measures. The trial studied Spirulina, not Chlorella. (LLM, conf=0.91)

    Experimental — accuracy not yet measured
  • Daily intake of Spirulina (2-4.5 g/day) over 8 to 12 weeks is consistently associated with improvements in systolic blood pressure, both as a standalone supplement and when incorporated into functional foods, whereas no comparable effects were observed in placebo groups.

    “Daily intake of Spirulina (2–4.5 g/day) over periods ranging from 8 to 12 weeks has consistently been associated with improvements in systolic blood pressure, both as a standalone supplement and when incorporated into functional foods, whereas no comparable effects were observed in placebo groups [74–76].”

  • In patients with systemic arterial hypertension undergoing treatment with ACE inhibitors, 4.5 g administration of Arthrospira platensis for 12 weeks resulted in a statistically significant decrease in systolic blood pressure, sVCAM-1, sE-selectin and endothelin-1 levels as well as an increase in glutathione peroxidase activity and oxidized glutathione levels.

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.
