Spirulina supplementation during gradual weight loss significantly reduces serum myostatin (MST) and liver enzymes (AST, ALT) compared to placebo, suggesting a protective effect on the liver and a reduction in the catabolic environment.
Spirulina supplementation (3g/day) during your weight cut may help protect your liver and reduce catabolic stress. The study showed significant reductions in liver enzymes (AST, ALT) and myostatin (a hormone that limits muscle growth) in wrestlers taking spirulina compared to placebo. This suggests spirulina may help create a less catabolic environment during weight loss.
MST (SP = –0.1 ng/ml... P = 0.005) concentrations significantly diminished in SP group... AST (SP = −2.1 u/l... P = 0.007) and ALT (SP = −2.7 u/l... P = 0.002) significantly decreased in SP group.
Why this rating
Same study as N1, RCT design, small sample size, but clear statistical significance for these specific markers.

- Spirulina supplementation (3000 mg/day) during a 12-day gradual weight loss protocol significantly enhances fat mass loss and body fat percentage reduction compared to placebo in competitive wrestlers, while maintaining skeletal muscle mass and reducing catabolic myostatin levels.Good
- Spirulina supplementation does NOT significantly preserve skeletal muscle mass (SMM) during gradual weight loss compared to placebo; both groups lost similar amounts of muscle mass.Good
