Sicilian Blood Orange Complex
Also known as: Sicilian Blood Orange Complex, Red Orange Complex, ROC™, Citrus sinensis
Overview
Sicilian Blood Orange Complex is a standardized botanical extract derived from three specific pigmented Sicilian blood orange varieties: Moro, Tarocco, and Sanguinello. This complex is rich in a defined mix of bioactive compounds, including anthocyanins (specifically cyanidin-3-glucoside), hydroxycinnamic acids, ascorbic acid (vitamin C), and flavanones (such as hesperidin and narirutin). It is primarily utilized as an antioxidant and anti-inflammatory dietary supplement, with its applications focusing on reducing oxidative stress, providing photoprotection for the skin, and offering anti-aging benefits. The extract is typically administered in capsule form, with a common dosage of 100 mg per day. While research on this specific complex is still developing, it includes well-designed randomized controlled trials (RCTs) that utilize standardized formulations and placebo controls, indicating a moderate quality of evidence for its reported effects.
Benefits
The Sicilian Blood Orange Complex offers several evidence-based benefits, primarily centered around its antioxidant and skin-protective properties. Its primary effects include significant antioxidant and anti-inflammatory efficacy, demonstrated in elderly subjects who showed improvements in markers of oxidative stress and overall well-being after supplementing with 100 mg/day for two months. Furthermore, it exhibits photoprotective and anti-aging effects on the skin, observed in both Asian and Caucasian subjects. Studies have shown improvements in skin hydration, elasticity, and a reduction in UV-induced damage after two months of supplementation. These benefits are particularly relevant for elderly adults and individuals frequently exposed to UV radiation. Secondary effects suggest potential modulation of nitric oxide (NO) levels and anti-inflammatory activity in macrophage models, hinting at immune-modulatory properties. Benefits typically become apparent after 4 to 8 weeks of consistent daily supplementation at the 100 mg dose. Studies report statistically significant improvements (p < 0.05) in relevant biomarkers and skin parameters.
How it works
The Sicilian Blood Orange Complex primarily exerts its effects through potent antioxidant pathways. Its rich content of anthocyanins, flavanones, and vitamin C enables it to effectively scavenge reactive oxygen species (ROS), thereby reducing oxidative damage at a cellular level. The anthocyanins and flavanones also play a crucial role in inhibiting inflammatory mediators and modulating endothelial function, partly through their influence on nitric oxide pathways. Additionally, the ascorbic acid component contributes directly to collagen synthesis, which is vital for skin repair and maintaining skin integrity. The bioactive compounds are absorbed in the gut, with anthocyanins exhibiting moderate bioavailability, which can be enhanced when consumed with food.
Side effects
The Sicilian Blood Orange Complex generally exhibits a favorable safety profile and is well-tolerated, with no serious adverse events reported in clinical trials at the studied dosages. Common side effects are rare, and there have been no significant gastrointestinal disturbances or allergic reactions documented. Currently, there are no known drug interactions or contraindications reported in the scientific literature for this complex. However, it is important to note that the safety of Sicilian Blood Orange Complex has not been established for specific populations, including pregnant or lactating women, or children. Therefore, its use in these groups is not recommended without further research and medical consultation. Individuals with known allergies to citrus fruits should exercise caution.
Dosage
The minimum effective dose for Sicilian Blood Orange Complex, as supported by clinical trials, is 100 mg per day of the standardized Red Orange Complex extract. This 100 mg/day dosage is also considered the optimal dose, as it has consistently shown efficacy in randomized controlled trials. While a maximum safe dose has not been definitively established, no adverse effects have been reported at the 100 mg/day level. It is generally recommended to take the supplement once daily, preferably after breakfast, to potentially improve absorption and ensure consistent compliance. The complex should be consumed in an encapsulated extract form, standardized for its key bioactive compounds, including anthocyanins, flavanones, hydroxycinnamic acids, and vitamin C, to ensure consistent potency and efficacy.
FAQs
Is Sicilian Blood Orange Complex safe for long-term use?
Current evidence supports its safety for at least two months of continuous use. However, data on longer-term safety beyond this period are limited, and further research is needed.
How soon can I expect to see benefits from taking this supplement?
Improvements in markers of oxidative stress and skin parameters, such as hydration and elasticity, generally begin to appear within 4 to 8 weeks of consistent daily supplementation.
Can Sicilian Blood Orange Complex replace my regular vitamin C supplement?
While it contains vitamin C, the complex is primarily valued for its unique blend of polyphenols, particularly anthocyanins. It is not intended as a direct substitute for dedicated vitamin C supplementation.
Does this supplement affect cholesterol or blood sugar levels?
A 4-week randomized controlled trial found no significant effect on LDL cholesterol or glycemic markers when compared to standard orange juice, suggesting no direct impact on these parameters.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC9611767/ – This double-blind, placebo-controlled RCT involving 60 elderly subjects over 2 months demonstrated that Sicilian Blood Orange Complex (100 mg/day) significantly improved antioxidant and anti-inflammatory markers, leading to enhanced overall well-being. The study highlights the complex's potential in mitigating age-related oxidative stress.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC9182634/ – This RCT, involving 60 healthy adults of Asian and Caucasian descent, showed that 2 months of supplementation with Sicilian Blood Orange Complex (100 mg/day) provided significant photoprotective and anti-aging effects on the skin. Key findings included improved skin hydration, elasticity, and reduced UV-induced damage, supporting its use for skin health.
