Moro blood orange extract,
does it really help with Reduction of abdominal fat, waist circumference, and body weight?
research showsSmall placebo-controlled trials of Morosil® at 400 mg/day and a meta-analysis of three RCTs with 252 participants show signals of reduced weight and fat mass. The evidence is concentrated in a few studies of the same branded ingredient with supplier support or product provision. Pooled waist results were extremely heterogeneous, and the outcomes were body-composition and circumference surrogates. The grade is C.

Useful facts when choosing a product
- The Korean recognized-ingredient notice specifies 400 mg/day as Morosil®.
- The trials used standardized Morosil®, so results do not automatically apply to generic blood-orange powder, juice, or mixtures with unclear content.
- Weight trials included calorie control and exercise and do not show that the extract replaces lifestyle measures.
- The longest published RCT lasted six months; pregnancy, lactation, long-term use, and interaction data remain limited.
What the research actually shows
The Cardile 2015 trial gave 60 overweight adults 400 mg/day for 12 weeks and reported reductions in weight, BMI, waist, and hip circumference. The Briskey 2022 trial analyzed 136 participants by intention to treat from 180 enrollees and, with diet and exercise, reported 4.2% versus 2.2% weight loss and 3.9 versus 1.7 cm waist reduction after six months; Bionap supplied products and paid the article charge. The Campos 2026 meta-analysis pooled three RCTs with 252 participants but found 99% heterogeneity for waist circumference.
Why this is classified as C (55)
Positive RCTs and a meta-analysis exist, but trial count and sample size are small and the evidence is concentrated in a supplier-linked branded ingredient. The C ceiling applies. Repeated weight and fat signals justify 55 points; safety, HACCP, and product identity are separate.
Counterpoint. A sufficiently powered independent trial with prespecified outcomes and long-term weight maintenance is needed.
Rejudgment record. Reassessment (cross-check reflected) — Retained C after accounting for the Morosil branded ingredient, Bionap product and publication support, concomitant diet and exercise, and insufficient independent replication
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduction in body weight and fat mass | C | Positive pooling of three small Morosil® RCTs with branded-ingredient concentration |
| Reduction in abdominal fat and waist circumference | C | DEXA and circumference surrogates; waist meta-analysis I²=99% |

| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Cardile et al. (2015) | Randomized double-blind placebo-controlled trial, 12 weeks | 60 | Morosil® branded ingredient; supplier involvement details unclear | Weight, BMI, waist, and hip circumference | Reported reductions versus placebo at 400 mg/day | Supportive |
| Briskey et al. (2022) | Randomized double-blind placebo-controlled trial, six months | 136 | Bionap supplied products and paid the article-processing charge | Weight, circumferences, and DEXA fat mass | Improved weight, waist, and fat measures with concurrent diet and exercise | Key |
| Campos et al. (2026) | Systematic review and meta-analysis | 252 | Review funding unclear; underlying trials centered on branded ingredients | Weight, BMI, waist, and fat mass | Weight -2.08 kg and fat mass -1.53 kg; waist I²=99% | Key |
