About Moro Red Orange (Morosil)
A standardized anthocyanin-rich extract of the Moro blood orange (Citrus sinensis), branded Morosil, marketed for waist/weight reduction. Three RCTs (pooled n≈252, incl. Briskey 2022 n=180 over 6 months) report modest effects at 400 mg/day, but every trial is manufacturer (Bionap) funded and a 2025 independent meta-analysis (Campos et al., PMID 40956687) rated the certainty LOW-to-VERY-LOW with very high heterogeneity (I²≈99%). Treat as preliminary, single-source evidence.
What Moro Red Orange (Morosil) supports
- Blood-orange extract studied at 400mg for waist/weight; low certainty
How much Moro Red Orange (Morosil) to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
400–400
mg
Every Morosil RCT used 400 mg/day; no evidence below 400, so the range is fixed (a lower floor would hand half-dose credit the trials don't support).
Clinical evidence
Limited clinical evidence. 3 manufacturer-funded RCTs at 400mg; 2025 meta rates certainty low-to-very-low (I²≈99%)
