A randomized, double blind, placebo controlled study of spirulina supplementation on indices of mental and physical fatigue in men
Abstract
Spirulina may increase people's ability to resist mental and physical fatigue. This study tested that hypothesis in a randomized, double blinded, placebo controlled study in men. After 1 week, a 3 g/day dose of spirulina produced a small, but statistically significant increase in exercise output (Kcals consumed in 30 min exercise on a cross trainer machine). A mathematical based mental fatigue test showed improved performance 4 h after the first time of supplementation as well as 8 weeks later. Similarly, a subjective survey for a sense of physical and mental fatigue showed improvement within 4 h of the first supplementation as well as 8 weeks later. These results show that spirulina intake can affect fatigue in men.

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.
