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.

If you are a wrestler cutting weight, adding 3 grams of spirulina daily (split into 3 doses before meals) to your gradual weight loss diet can help you lose more fat than dieting alone. In this study, wrestlers taking spirulina lost significantly more fat mass and body fat percentage over 12 days compared to those taking a placebo. However, spirulina did not prevent muscle loss; both groups lost similar amounts of muscle. To preserve muscle, ensure your protein intake is high (1.6-3.1 g/kg/day) alongside the spirulina and diet.

The changes in BFP (Fig. 2(d), P < 0·001) and FM (Fig. 2(f), P < 0·001) were significantly higher in SP compared with PL group... Interestingly, it was observed that the reduction in BFP and FM was greater after SP. It seems that adding spirulina supplementation to the gradual weight loss protocol can target weight loss in such a way, that it tends to be more effective through BFP and FM reduction.

Why this rating

Randomized, double-blind, placebo-controlled trial with a relevant athletic population, though the sample size is small (n=40) and duration is short (12 days).
