A pair of heavyweight papers dropped in June and July 2025, each pooling dozens of randomized trials and more than 1,600 volunteers. Together they tighten the evidence that daily spirulina does two things modern diets struggle to deliver: trim fat mass and re-balance blood lipids.

1. The Body-Composition Meta-Analysis (Nutrition & Metabolism, 17 June 2025)

Researchers aggregated 11 trials (649 adults) and found a –1.07 kg average weight loss along with parallel drops in BMI and body-fat percentage when spirulina was stacked against placebo. The signal got stronger when doses exceeded 2 g a day and when the programs ran 12 weeks or longer. (Link)

Who benefited most? Sub-analysis showed the steepest declines in participants over 40 or beginning in the obese range.

2. The Cardiometabolic Meta-Analysis (Frontiers in Nutrition, 27 June 2025) 

Across 23 trials (1,035 participants), spirulina clipped multiple risk markers in one go:

• Total cholesterol: ↓ 0.79 SD

• LDL-C: ↓ 0.71 SD

• Triglycerides: ↓ 0.64 SD

• HDL-C: ↑ 0.53 SD

A modest reduction in body weight (g = –0.30) also showed up, and pairing spirulina with structured exercise pushed HDL even higher while pressing LDL lower. (Link)

Quick take-aways

• Clinical evidence keeps piling up—spirulina supports both healthy body composition and balanced blood lipids.

• Consistency over a dozen weeks was the common thread across the new studies.

• Even modest movement (a brisk walk or light lift session) helped amplify the benefits.

One pod, all the science

A single New Farmers frozen pod packs well above the study-tested threshold—fresh, raw, and oxidation-free. Blend it daily for three months and you’ll mirror the research protocols without measuring scoops or swallowing capsules. Stock a 90-pod sleeve, set a calendar reminder, and let the data do the talking.
